数据库操作(PaintingliteSessionManager)

1.建库

创建PaintingliteSessionManager,通过管理者创建数据库。

- (Boolean)openSqlite:(NSString *)fileName;

- (Boolean)openSqlite:(NSString *)fileName completeHandler:(void(^ __nullable)(NSString *filePath,PaintingliteSessionError *error,Boolean success))completeHandler;

Paintinglite具有良好的处理机制,通过传入数据库名称进行创建数据库,即使数据库后缀不规范,它仍能创建出.db后缀的数据库。

[self.sessionM openSqlite:@"sqlite"];
[self.sessionM openSqlite:@"sqlite02.db"];
[self.sessionM openSqlite:@"sqlite03.image"];
[self.sessionM openSqlite:@"sqlite04.text"];
[self.sessionM openSqlite:@"sqlite05.."];

获得创建数据库的绝对路径。

[self.sessionM openSqlite:@"sqlite" completeHandler:^(NSString * _Nonnull filePath, PaintingliteSessionError * _Nonnull error, Boolean success) {
       if (success) {
           NSLog(@"%@",filePath);
        }
 }];

2.关闭库

- (Boolean)releaseSqlite;

- (Boolean)releaseSqliteCompleteHandler:(void(^)(PaintingliteSessionError *error,Boolean success))completeHandler;

3.创建表

- (Boolean)execTableOptForSQL:(NSString *)sql;
- (Boolean)execTableOptForSQL:(NSString *)sql completeHandler:(void(^ __nullable)(PaintingliteSessionError *error,Boolean success))completeHandler;
- (Boolean)createTableForName:(NSString *)tableName content:(NSString *)content;
- (Boolean)createTableForName:(NSString *)tableName content:(NSString *)content completeHandler:(void(^ __nullable)(PaintingliteSessionError *error,Boolean success))completeHandler;
- (Boolean)createTableForObj:(id)obj createStyle:(PaintingliteDataBaseOptionsCreateStyle)createStyle;
- (Boolean)createTableForObj:(id)obj createStyle:(PaintingliteDataBaseOptionsCreateStyle)createStyle completeHandler:(void(^ __nullable)(PaintingliteSessionError *error,Boolean success))completeHandler;

创建表的三种方式：

SQL创建

[self.sessionM execTableOptForSQL:@"CREATE TABLE IF NOT EXISTS cart(UUID VARCHAR(20) NOT NULL PRIMARY KEY,shoppingName TEXT,shoppingID INT(11))" completeHandler:^(PaintingliteSessionError * _Nonnull error, Boolean success) {
        if (success) {
            NSLog(@"===CREATE TABLE SUCCESS===");
        }
}];

表名创建

[self.sessionM createTableForName:@"student" content:@"name TEXT,age INTEGER"];

对象创建

User *user = [[User alloc] init];
[self.sessionM createTableForObj:user createStyle:PaintingliteDataBaseOptionsUUID];

对象创建可以自动生成主键:

主键	类型
UUID	字符串
ID	数值

4.更新表

- (Boolean)execTableOptForSQL:(NSString *)sql;
- (Boolean)execTableOptForSQL:(NSString *)sql completeHandler:(void(^ __nullable)(PaintingliteSessionError *error,Boolean success))completeHandler;
- (BOOL)alterTableForName:(NSString *__nonnull)oldName newName:(NSString *__nonnull)newName;
- (BOOL)alterTableForName:(NSString *__nonnull)oldName newName:(NSString *__nonnull)newName completeHandler:(void(^ __nullable)(PaintingliteSessionError *error,Boolean success))completeHandler;
- (BOOL)alterTableAddColumnWithTableName:(NSString *)tableName columnName:(NSString *__nonnull)columnName columnType:(NSString *__nonnull)columnType;
- (BOOL)alterTableAddColumnWithTableName:(NSString *)tableName columnName:(NSString *__nonnull)columnName columnType:(NSString *__nonnull)columnType completeHandler:(void(^ __nullable)(PaintingliteSessionError *error,Boolean success))completeHandler;
- (BOOL)alterTableForObj:(id)obj;
- (BOOL)alterTableForObj:(id)obj completeHandler:(void(^ __nullable)(PaintingliteSessionError *error,Boolean success))completeHandler;

更新表三种方式:

SQL更新
表名更新 [ 表名称 | 表字段 ]

[self.sessionM alterTableForName:@"cart" newName:@"carts"];
[self.sessionM alterTableAddColumnWithTableName:@"carts" columnName:@"newColumn" columnType:@"TEXT"];

对象更新
更新User表操作

#import 

NS_ASSUME_NONNULL_BEGIN

@interface User : NSObject

@property (nonatomic,strong)NSString *name;
@property (nonatomic,strong)NSNumber *age;
@property (nonatomic,strong)NSMutableArray *mutableArray;

@end

NS_ASSUME_NONNULL_END

根据表和对象的映射关系,自动根据对象更新表字段。

User *user = [[User alloc] init];
[self.sessionM alterTableForObj:user];

5.删除操作

- (Boolean)execTableOptForSQL:(NSString *)sql;
- (Boolean)execTableOptForSQL:(NSString *)sql completeHandler:(void(^ __nullable)(PaintingliteSessionError *error,Boolean success))completeHandler;
- (Boolean)dropTableForTableName:(NSString *)tableName;
- (Boolean)dropTableForTableName:(NSString *)tableName completeHandler:(void(^)(PaintingliteSessionError *error,Boolean success))completeHandler;
- (Boolean)dropTableForObj:(id)obj;
- (Boolean)dropTableForObj:(id)obj completeHandler:(void(^)(PaintingliteSessionError *error,Boolean success))completeHandler;

删除表的三种方法:

SQL操作
表名删除

[self.sessionM execTableOptForSQL:@"DROP TABLE carts" completeHandler:^(PaintingliteSessionError * _Nonnull error, Boolean success) {
        if (success) {
            NSLog(@"===DROP TABLE SUCCESS===");
        }
}];

对象删除

User *user = [[User alloc] init];
[self.sessionM dropTableForObj:user];

表操作

1.查询

查询可以提供查询结果用数组封装或者采用对象直接封装的特点。

普通查询

一般查询

- (NSMutableArray *)execQuerySQL:(NSString *__nonnull)sql;
- (Boolean)execQuerySQL:(NSString *__nonnull)sql completeHandler:(void(^ __nullable)(PaintingliteSessionError *error,Boolean success,NSMutableArray *resArray))completeHandler;

[self.sessionM execQuerySQL:@"SELECT * FROM student" completeHandler:^(PaintingliteSessionError * _Nonnull error, Boolean success, NSMutableArray * _Nonnull resArray) {
        if (success) {
            for (NSDictionary *dict in resArray) {
                NSLog(@"%@",dict);
            }
        }
}];

2020-06-27 15:35:45.967569+0800 Paintinglite[5805:295051] {
age = 21;
name = CreaterOS;
}
2020-06-27 15:35:45.967760+0800 Paintinglite[5805:295051] {
age = 19;
name = Painting;
}
2020-06-27 15:35:45.967879+0800 Paintinglite[5805:295051] {
age = 21;
name = CreaterOS;
}

封装查询

封装查询可以将查询结果封装到与表字段相对应的对象中。

- (id)execQuerySQL:(NSString *__nonnull)sql obj:(id)obj;
- (Boolean)execQuerySQL:(NSString *__nonnull)sql obj:(id)obj completeHandler:(void(^ __nullable)(PaintingliteSessionError *error,Boolean success,NSMutableArray *resArray,NSMutableArray *resObjList))completeHandler;

Student *stu = [[Student alloc] init];
[self.sessionM execQuerySQL:@"SELECT * FROM student" obj:stu completeHandler:^(PaintingliteSessionError * _Nonnull error, Boolean success, NSMutableArray * _Nonnull resArray, NSMutableArray * _Nonnull resObjList) {
  if (success) {
    for (Student *stu in resObjList) {
      NSLog(@"stu.name = %@ and stu.age = %@",stu.name,stu.age);
    }
  }
}];

2020-06-27 15:39:27.306786+0800 Paintinglite[5892:302879] stu.name = CreaterOS and stu.age = 21
2020-06-27 15:39:27.306961+0800 Paintinglite[5892:302879] stu.name = Painting and stu.age = 19
2020-06-27 15:39:27.307110+0800 Paintinglite[5892:302879] stu.name = CreaterOS and stu.age = 21

条件查询

条件查询语法规则:

下标从0开始

条件参数使用?作占位符

SELECT * FROM user WHERE name = ? and age = ?

- (NSMutableArray *)execPrepareStatementSql;
- (Boolean)execPrepareStatementSqlCompleteHandler:(void(^ __nullable)(PaintingliteSessionError *error,Boolean success,NSMutableArray *resArray))completeHandler;

[self.sessionM execQuerySQLPrepareStatementSql:@"SELECT * FROM student WHERE name = ?"];
[self.sessionM setPrepareStatementPQLParameter:0 paramter:@"CreaterOS"];
NSLog(@"%@",[self.sessionM execPrepareStatementSql]);

2020-06-27 15:44:06.664951+0800 Paintinglite[5984:310580] (
{
age = 21;
name = CreaterOS;
},
{
age = 21;
name = CreaterOS;
}
)

模糊查询

- (NSMutableArray *)execLikeQuerySQLWithTableName:(NSString *__nonnull)tableName field:(NSString *__nonnull)field like:(NSString *__nonnull)like;
- (Boolean)execLikeQuerySQLWithTableName:(NSString *__nonnull)tableName field:(NSString *__nonnull)field like:(NSString *__nonnull)like completeHandler:(void(^)(PaintingliteSessionError *error,Boolean success,NSMutableArray *resArray))completeHandler;

[self.sessionM execLikeQuerySQLWithTableName:@"student" field:@"name" like:@"%t%" completeHandler:^(PaintingliteSessionError * _Nonnull error, Boolean success, NSMutableArray * _Nonnull resArray) {
        if (success) {
            for (NSDictionary *dict in resArray) {
                NSLog(@"%@",dict);
            }
        }
}];

Student *stu = [[Student alloc] init];
[self.sessionM execLikeQuerySQLWithField:@"name" like:@"%t%" obj:stu completeHandler:^(PaintingliteSessionError * _Nonnull error, Boolean success, NSMutableArray * _Nonnull resArray, NSMutableArray * _Nonnull resObjList) {
  if (success) {
    for (NSDictionary *dict in resArray) {
      NSLog(@"%@",dict);
    }
  }
}];

}];

Student *stu = [[Student alloc] init];
[self.sessionM execLimitQuerySQLWithLimitStart:0 limitEnd:1 obj:stu completeHandler:^(PaintingliteSessionError * _Nonnull error, Boolean success, NSMutableArray * _Nonnull resArray, NSMutableArray * _Nonnull resObjList) {
  if (success) {
    for (Student *stu in resObjList) {
      NSLog(@"stu.name = %@ and stu.age = %@",stu.name,stu.age);
    }
  }
}];

2020-06-27 15:51:13.026776+0800 Paintinglite[6117:323796] stu.name = CreaterOS and stu.age = 21

排序查询

- (NSMutableArray *)execOrderByQuerySQLWithTableName:(NSString *__nonnull)tableName orderbyContext:(NSString *__nonnull)orderbyContext orderStyle:(PaintingliteOrderByStyle)orderStyle;
- (Boolean)execOrderByQuerySQLWithTableName:(NSString *__nonnull)tableName orderbyContext:(NSString *__nonnull)orderbyContext orderStyle:(PaintingliteOrderByStyle)orderStyle completeHandler:(void(^)(PaintingliteSessionError *error,Boolean success,NSMutableArray *resArray))completeHandler;

Student *student = [[Student alloc] init];
[self.sessionM execOrderByQuerySQLWithOrderbyContext:@"name" orderStyle:PaintingliteOrderByDESC obj:student completeHandler:^(PaintingliteSessionError * _Nonnull error, Boolean success, NSMutableArray * _Nonnull resArray, NSMutableArray * _Nonnull resObjList) {
  if (success) {
    for (Student *stu in resObjList) {
      NSLog(@"stu.name = %@ and stu.age = %@",stu.name,stu.age);
    }
  }
}];

2020-06-27 15:55:06.714604+0800 Paintinglite[6196:331097] stu.name = Painting and stu.age = 19
2020-06-27 15:55:06.714801+0800 Paintinglite[6196:331097] stu.name = CreaterOS and stu.age = 21
2020-06-27 15:55:06.714962+0800 Paintinglite[6196:331097] stu.name = CreaterOS and stu.age = 21

2.增加数据

- (Boolean)insert:(NSString *__nonnull)sql;
- (Boolean)insert:(NSString *__nonnull)sql completeHandler:(void(^ __nullable)(PaintingliteSessionError *error,Boolean success))completeHandler;
- (Boolean)insertWithObj:(id)obj completeHandler:(void(^ __nullable)(PaintingliteSessionError *error,Boolean success))completeHandler;

SQL插入

[self.sessionM insert:@"INSERT INTO student(name,age) VALUES('CreaterOS',21),('Painting',19)"];

对象插入

#import 

NS_ASSUME_NONNULL_BEGIN

@interface Student : NSObject
@property (nonatomic,strong)NSString *name;
@property (nonatomic,strong)NSNumber *age;
@end

NS_ASSUME_NONNULL_END

Student *stu = [[Student alloc] init];
stu.name = @"ReynBryant";
stu.age = [NSNumber numberWithInteger:21];
[self.sessionM insertWithObj:stu completeHandler:nil];

对于庞大数据量,Paintinglit仍能够表现出良好的效率，通过一次性读入1千6百万条数据只耗时6ms-7ms。

3.更新数据

- (Boolean)update:(NSString *__nonnull)sql;
- (Boolean)update:(NSString *__nonnull)sql completeHandler:(void(^)(PaintingliteSessionError *error,Boolean success))completeHandler;
- (Boolean)updateWithObj:(id)obj condition:(NSString *__nonnull)condition completeHandler:(void(^)(PaintingliteSessionError *error,Boolean success))completeHandler;

SQL更新数据

[self.sessionM update:@"UPDATE student SET name = 'Painting' WHERE name = 'ReynBryant'"];

对象更新

Student *stu = [[Student alloc] init];
stu.name = @"CreaterOS";
[self.sessionM updateWithObj:stu condition:@"age = 21" completeHandler:nil];

增加更新操作,可以通过对象传值方式进行更新
例如：
User *user = [[User alloc] init];
user.name = @"CreaterOS";
user.age = 21;

4.删除数据

- (Boolean)del:(NSString *__nonnull)sql;
- (Boolean)del:(NSString *__nonnull)sql completeHandler:(void(^)(PaintingliteSessionError *error,Boolean success))completeHandler;

PQL语法(PaintingliteSessionManager)

通过PQL语句,Paintinglite可以自动帮您完成SQL语句的书写。

PQL语法规则(大写 | 类名一定要和表关联)
FROM + 类名称 + [条件]

- (id)execPrepareStatementPQL;
- (Boolean)execPrepareStatementPQLWithCompleteHandler:(void(^)(PaintingliteSessionError *error,Boolean success,NSMutableArray *resArray,NSMutableArray* resObjList))completeHandler;

- (void)execQueryPQLPrepareStatementPQL:(NSString *__nonnull)prepareStatementPQL;
- (void)setPrepareStatementPQLParameter:(NSUInteger)index paramter:(NSString *__nonnull)paramter;
- (void)setPrepareStatementPQLParameter:(NSArray *__nonnull)paramter;

- (id)execPQL:(NSString *__nonnull)pql;
- (Boolean)execPQL:(NSString *__nonnull)pql completeHandler:(void(^)(PaintingliteSessionError *error,Boolean success,NSMutableArray *resArray,NSMutableArray* resObjList))completeHandler;

[self.sessionM execPQL:@"FROM Student WHERE name = 'CreaterOS'" completeHandler:^(PaintingliteSessionError * _Nonnull error, Boolean success, NSMutableArray * _Nonnull resArray, NSMutableArray * _Nonnull resObjList) {
        if (success) {
            for (Student *stu in resObjList) {
                NSLog(@"stu.name = %@ and stu.age = %@",stu.name,stu.age);
            }
        }
}];

2020-06-27 16:16:47.145774+0800 Paintinglite[6753:369828] stu.name = CreaterOS and stu.age = 21
2020-06-27 16:16:47.145928+0800 Paintinglite[6753:369828] stu.name = CreaterOS and stu.age = 21

[self.sessionM execPQL:@"FROM Student LIMIT 0,1" completeHandler:^(PaintingliteSessionError * _Nonnull error, Boolean success, NSMutableArray * _Nonnull resArray, NSMutableArray * _Nonnull resObjList) {
        if (success) {
            for (Student *stu in resObjList) {
                NSLog(@"stu.name = %@ and stu.age = %@",stu.name,stu.age);
            }
        }
}];

[self.sessionM execPQL:@"FROM Student WHERE name LIKE '%t%'" completeHandler:^(PaintingliteSessionError * _Nonnull error, Boolean success, NSMutableArray * _Nonnull resArray, NSMutableArray * _Nonnull resObjList) {
        if (success) {
            for (Student *stu in resObjList) {
                NSLog(@"stu.name = %@ and stu.age = %@",stu.name,stu.age);
            }
        }
}];

[self.sessionM execPQL:@"FROM Student ORDER BY name ASC" completeHandler:^(PaintingliteSessionError * _Nonnull error, Boolean success, NSMutableArray * _Nonnull resArray, NSMutableArray * _Nonnull resObjList) {
        if (success) {
            for (Student *stu in resObjList) {
                NSLog(@"stu.name = %@ and stu.age = %@",stu.name,stu.age);
            }
        }
}];

[self.sessionM execQueryPQLPrepareStatementPQL:@"FROM Student WHERE name = ?"];
[self.sessionM setPrepareStatementPQLParameter:@[@"CreaterOS"]];
NSLog(@"%@",[self.sessionM execPrepareStatementPQL]);

2020-06-27 16:26:11.404815+0800 Paintinglite[7025:389268] (

聚合函数(PaintingliteAggregateFunc)

Paintinglite封装Sqlite3聚合函数,自动写入SQL语句就可以得到聚合结果。

Count

[self.aggreageteF count:[self.sessionM getSqlite3] tableName:@"eletest" completeHandler:^(PaintingliteSessionError * _Nonnull sessionerror, Boolean success, NSUInteger count) {
        if (success) {
            NSLog(@"%zd",count);
        }
 }];

[self.aggreageteF max:[self.sessionM getSqlite3] field:@"age" tableName:@"eletest" completeHandler:^(PaintingliteSessionError * _Nonnull sessionerror, Boolean success, double max) {
        if (success) {
            NSLog(@"%.2f",max);
        }
}];

[self.aggreageteF min:[self.sessionM getSqlite3] field:@"age" tableName:@"eletest" completeHandler:^(PaintingliteSessionError * _Nonnull sessionerror, Boolean success, double min) {
        if (success) {
            NSLog(@"%.2f",min);
        }
}];

[self.aggreageteF sum:[self.sessionM getSqlite3] field:@"age" tableName:@"eletest" completeHandler:^(PaintingliteSessionError * _Nonnull sessionerror, Boolean success, double sum) {
        if (success) {
            NSLog(@"%.2f",sum);
        }
}];

[self.aggreageteF avg:[self.sessionM getSqlite3] field:@"age" tableName:@"eletest" completeHandler:^(PaintingliteSessionError * _Nonnull sessionerror, Boolean success, double avg) {
        if (success) {
            NSLog(@"%.2f",avg);
        }
}];

事务(PaintingliteTransaction)

Sqlite3开发默认一条插入语句是一个事务,假设有多个插入语句则会重复开起事务,这对资源消耗是巨大的,Paintinglite提供了开起事务的操作(显示事务)。

+ (void)begainPaintingliteTransaction:(sqlite3 *)ppDb;
+ (void)commit:(sqlite3 *)ppDb;
+ (void)rollback:(sqlite3 *)ppDb;

日常开发结合

@try {
} @catch (NSException *exception) {
} @finally {
}

使用

级联操作(PaintingliteCascadeShowerIUD)

- (Boolean)cascadeInsert:(sqlite3 *)ppDb obj:(id)obj completeHandler:(void (^ __nullable)(PaintingliteSessionError *sessionError,Boolean success,NSMutableArray *resArray))completeHandler;

- (Boolean)cascadeUpdate:(sqlite3 *)ppDb obj:(id)obj condatation:(NSArray * __nonnull)condatation completeHandler:(void (^__nullable)(PaintingliteSessionError *sessionError,Boolean success,NSMutableArray *resArray))completeHandler;

- (Boolean)cascadeDelete:(sqlite3 *)ppDb obj:(id)obj condatation:(NSArray * __nonnull)condatation completeHandler:(void (^__nullable)(PaintingliteSessionError *sessionError,Boolean success,NSMutableArray *resArray))completeHandler;

级联分为三个部分:

插入

级联插入操作,我们需要将两个有关系的表通过可变数组进行连接,例如:
user表和student表有联系,
一个user可以包含多个student

那么,可以在user中设置可变数据保存多个student,然后将user对象交给Paintinglite就可以一次写入多个表的数据。

User *user = [[User alloc] init];
user.name = @"Jay";
user.age = [NSNumber numberWithInteger:40];
user.studentsArray = [NSMutableArray array];

Student *student = [[Student alloc] init];
student.name = @"Hony";
student.age = [NSNumber numberWithInteger:30];

Student *student1 = [[Student alloc] init];
student1.name = @"Jack";
student1.age = [NSNumber numberWithInteger:41];

[user.studentsArray addObject:student];
[user.studentsArray addObject:student1];

[self.cascade cascadeInsert:[self.sessionM getSqlite3] obj:user completeHandler:^(PaintingliteSessionError * _Nonnull sessionError, Boolean success, NSMutableArray * _Nonnull resArray) {
    if (success) {
        NSLog(@"%@",resArray);
    }
}];

更新
作用和级联插入相同,传入user对象,包含student表的集合,将修改条件以数组方式传入,Paintinglite可以自动实现多表的更新。(条件数组对应的多个表的不同条件)

name = 'CreaterOS' 对应user表

name = 'OS...' 对应student表

[self.cascade cascadeUpdate:[self.sessionM getSqlite3] obj:user condatation:@[@"WHERE name = 'CreaterOS'",@"WHERE name = 'OS...'"] completeHandler:^(PaintingliteSessionError * _Nonnull sessionError, Boolean success, NSMutableArray * _Nonnull resArray) {
     if (success) {
            NSLog(@"%@",resArray);
     }
 }];

删除

[self.cascade cascadeDelete:[self.sessionM getSqlite3] obj:user condatation:@[@"name = 'WHY'",@"name = 'YHD...'"] completeHandler:^(PaintingliteSessionError * _Nonnull sessionError, Boolean success, NSMutableArray * _Nonnull resArray) {
       if (success) {
           NSLog(@"%@",resArray);
       }
}];

日志模式(PaintingliteLog)

Paintinglite为开发者提供了日志记录功能,可以记录开发中对sqlite3数据的关键操作,并且标有时间戳,开发者可以通过数据库名称轻松读取日志,也可以根据需要的时间节点或者成功失败的状态选择性的读取日志。方便了软件上线后的调试。

- (void)readLogFile:(NSString *__nonnull)fileName;

- (void)readLogFile:(NSString *)fileName dateTime:(NSDate *__nonnull)dateTime;

- (void)readLogFile:(NSString *)fileName logStatus:(PaintingliteLogStatus)logStatus;

- (void)removeLogFile:(NSString *)fileName;

日志模块更新

通过一级缓存分批写入日志文件,建议开发在AppDelegate中实例化PaintingliteCache,在applicationDidEnterBackground:(UIApplication *)application和applicationWillTerminate:(UIApplication *)application中手动调用日志写入方法,则可以将未达到缓存基点的日志及时写入日志文件。

[self.cache pushCacheToLogFile];

数据库备份(PaintingliteBackUpManager)

数据库迁移是开发人员经常关心的问题,对于sqlite3移植客户端SQL Server MySQL 和 Orcale一直是一个头疼的问题。Paintinglite非常友好的为开发者提供了四种数据库的备份文件,包括从建库到插入数据,Paintinglite为开发者写入了备份文件,开发者只需要上传这些sql文件并运行就可以得到和移动设备完全一样的数据。

PaintingliteBackUpSqlite3,
PaintingliteBackUpMySql,
PaintingliteBackUpSqlServer,
PaintingliteBackUpORCALE

拆分表(PaintingliteSplitTable)

对于过大的数据量的表查询耗时操作是巨大的,Paintinglite测试阶段提供了拆分表的操作,将大表拆分成为多个小表,拆分的数额由开发者自己决定。
Paintinglite首次提供拆分表操作,模块尚在测试,后期版本迭代会重点优化这部分的资源消耗和CPU占用率问题。

/**
  * tableName: 数据库名称 
  * basePoint: 拆分个数 
  */
- (Boolean)splitTable:(sqlite3 *)ppDb tabelName:(NSString *__nonnull)tableName basePoint:(NSUInteger)basePoint;

查询操作

- (NSMutableArray *)selectWithSpliteFile:(sqlite3 *)ppDb tableName:(NSString *__nonnull)tableName basePoint:(NSUInteger)basePoint;

插入操作

- (Boolean)insertWithSpliteFile:(sqlite3 *)ppDb tableName:(NSString *)tableName basePoint:(NSUInteger)basePoint insertSQL:(NSString *)insertSQL;

更新操作

- (Boolean)updateWithSpliteFile:(sqlite3 *)ppDb tableName:(NSString *)tableName basePoint:(NSUInteger)basePoint updateSQL:(NSString *)updateSQL;

删除操作

- (Boolean)deleteWithSpliteFile:(sqlite3 *)ppDb tableName:(NSString *)tableName basePoint:(NSUInteger)basePoint deleteSQL:(NSString *)deleteSQL;

压力测试(PaintinglitePressureOS)

PaintinglitePressureOS系统是一个压力测试系统,它对于数据库读写消耗时间,资源消耗和内存的使用进行了合理性的评估,并支持生成压力测试报告。(默认不生成报告)

Paintinglite可以根据不同设备进行不同的测算内存消耗状态，让开发者更清楚在不同iPhone上设计更为合理的数据库表结构。

XML文件配置规则:

XML映射文件严格遵守DTD规则,其中提供了,,,,,,,等基本标签;
XML映射文件需对应表创建的类进行配置(POJO映射);
XML映射文件格式具有严格要求(v2.0版本对于要求严格);

XML映射文件层级关系

(1) 在进行配置XML映射文件,最外层标签为,mapper标签提供了命名空间namespace;

namespace: 表示当前SQL语句操作对象针对的表名称(这里不强制要求namespace内容,建议同操作表名称相同)

(2) 内部就可以进行数据库SQL操作的配置;

select: 查询标签

id: select绑定的ID
resultType: 结果返回类型,目前支持NSDictionary&&NSMutableDictionary | NSArray && NSMutableArray
parameterType: 传入类型(可变参数不需要配置,凡包含obj方法都必须配置parameterType)
select标签内部可以写入查询SQL语句
?: 需要替代部分采用?即可

select: 省略查询

当需要使用select * from tableName查询,可以省略SQL语句,通过一个?代替需要写入的SQL语句即可

insert: 插入标签

#import 

NS_ASSUME_NONNULL_BEGIN

@interface Eletest : NSObject
@property (nonatomic,strong)NSNumber *age;
@property (nonatomic,copy)NSString *desc;
@property (nonatomic,copy)NSString *name;
@property (nonatomic,strong)NSNumber *tage;
@property (nonatomic,copy)NSString *teacher;
@end

NS_ASSUME_NONNULL_END


INSERT INTO eletest(name,age,desc,tage,teacher) VALUES (#name,#age,#desc,#tage,#teacher);



?

id: insert标签绑定ID
parameterType: 传入参数,这里必须配置,为POJO对象的类名称(注意大小写)

name,#age,#desc,#tage,#teacher: 将插入的值利用“#+类属性名称”构成的组合体进行替代

insert支持省略插入语句,只需要给需要传入的对象设置对应属性值即可
useGeneratedKeys="true" keyProperty="ID": 返回插入的主键值



SELECT LAST_INSERT_ID();

?

也可以配置插入返回值

keyProperty="ID" : 主键值(对应属性值)
order="AFTER": 调用时机,可以配置AFTER&&BEFORE

update标签


UPDATE eletest SET name = #name and tage = #tage WHERE teacher = #teacher and age = #age;

id: update标签绑定ID
parameterType: 传入参数,这里必须配置,为POJO对象的类名称(注意大小写)

name,#age,#tage,#teacher: 将插入的值利用“#+类属性名称”构成的组合体进行替代

update支持省略插入语句,只需要给需要传入的对象设置对应属性值即可

delete标签


DELETE FROM eletest WHERE name = #name and teacher = #teacher and tage = #tage;



?

id: delete标签绑定ID
parameterType: 传入参数,这里必须配置,为POJO对象的类名称(注意大小写)

name,#teacher,#tage: 将插入的值利用“#+类属性名称”构成的组合体进行替代

delete支持省略插入语句,只需要给需要传入的对象设置对应属性值即可

XML映射文件高级使用

&&使用

id,name,age,teacher,tage,desc

通常操作SQL语句会书写select id,name,age,teacher,tage,desc From eletest字段进行查询,在一个XML映射文件中会用到多次字段名称,可以通过将字段名称包裹,在结合应用。

注意: 使用标签中配置refid传入值必须和配置id相同

动态SQL操作标签

PaintingliteXMLSessionManager 常用方法

/**
* 建立SessionManager
* xmlFileName: 每个类对应一个XML文件,传入XML文件名称
*/
+ (instancetype)buildSesssionManger:(NSString *__nonnull)xmlFileName;

/**
* 查询一个
* methodID: XML绑定的Select ID
* condition: 查询条件
*/
- (NSDictionary *)selectOne:(NSString *__nonnull)methodID condition:(id)condition,... NS_REQUIRES_NIL_TERMINATION;

/* 查询多个 */
- (NSArray *)select:(NSString *__nonnull)methodID condition:(id)condition,... NS_REQUIRES_NIL_TERMINATION;

- (NSArray *)select:(NSString *)methodID obj:(id)obj;

/**
* 插入
* methodID: XML绑定的INSERT ID
* obj: 插入的对象
*/
- (Boolean)insert:(NSString *)methodID obj:(id)obj;

/**
* 插入返回主键ID
* methodID: XML绑定的INSERT ID
* obj: 插入的对象
*/
- (sqlite3_int64)insertReturnPrimaryKeyID:(NSString *)methodID obj:(id)obj;

/**
* 更新
* methodID: XML绑定的INSERT ID
* obj: 插入的对象
*/
- (Boolean)update:(NSString *)methodID obj:(id)obj;

/**
* 删除
* methodID: XML绑定的INSERT ID
* obj: 插入的对象
*/
- (Boolean)del:(NSString *)methodID obj:(id)obj;

实例调用

PaintingliteXMLSessionManager *xmlSessionM = [PaintingliteXMLSessionManager buildSesssionManger:[[NSBundle mainBundle] pathForResource:@"user" ofType:@"xml"]];
[xmlSessionM openSqlite:@"sqlite"];

//查询
NSLog(@"%@",[xmlSessionM selectOne:@"eletest.getEleById" condition:[NSNumber numberWithInt:1],[NSNumber numberWithInt:21],nil]);
NSLog(@"%@",[xmlSessionM select:@"eletest.getEleById" condition:[NSNumber numberWithInt:1],[NSNumber numberWithInt:21], nil]);

Eletest *eletest = [[Eletest alloc] init];
eletest.name = @"CreaterOS";
eletest.age = [NSNumber numberWithInteger:21];
eletest.desc = @"CreaterOS";
eletest.teacher = @"CreaterOS";
eletest.tage = [NSNumber numberWithInteger:21];

NSLog(@"%zd",[[xmlSessionM select:@"eletest.getEleByObj" obj:eletest] count]);
NSLog(@"%zd",[[xmlSessionM select:@"eletest.getEleByObjWhere" obj:eletest] count]);

//插入
[xmlSessionM insert:@"eletest.getInsertEletest" obj:eletest];

NSLog(@"%lu",(unsigned long)[xmlSessionM insertReturnPrimaryKeyID:@"eletest.getInsertUserReturnPrimaryKey" obj:eletest]);

//删除
[xmlSessionM del:@"eletest.getDeleteUser" obj:eletest];
[xmlSessionM del:@"eletest.getDeleteEleAuto" obj:eletest];

//更新
[xmlSessionM update:@"eletest.getUpdateEle" obj:eletest];

约束

为了更好的实现操作,符合数据库规范,表名一律小写。
