Android sqlite3命令行操作方法

常用的一些命令解析:

 

 

创建表： create table table_name(filed1Name filed1Property,filed2Name filed2Property);

显示数据库中的表：.table

显示表结构：.schema table_name

删除表: .drop table table_name

退出：.exit

显示表所有内容: .dump table_name

导入数据：将txt文件中的数据到导入到表中, data.txt中每一列用”|”分隔, |两边不要空格,文件末尾不要有空行，例如：1|rainkey|tencent

注意：在android 上面执行的时候将text_name.txt存放到databases所在目录

.import text_name.txt table_name

插入记录：insert into table_name values(‘key’,’value’);

查找记录：select * from table_name;

从第三行开始查询10条记录：select * from table_name limit 3,10;

删除记录：delete from table_name where field1=value;

更新操作：update table_name set name=’rainkey’ where id=1;
