Android_SqLite数据库的创建与使用

一:数据库的创建:DBHelper

public class DBHelper extends SQLiteOpenHelper {

    private static final int VERSION = 1;
    private static String DB_NAME = "_name.db";
   
    private String CREATE_TABLE_PERSONS = "create table persons(_id integer primary key,prohibition integer,caseId integer,user_id integer, case_member_id integer,truename text,sex integer,mobile text," +
            "occupation text,birthday text,paper_type integer,paper_num text,employer text,address text,role integer," +
            "relation_member_id integer,type_name text,licence_type text,licence_num text,hxId text)";
   

    public DBHelper(Context context) {
        super(context, SPUtil.getInstance(context).getUserId() + DB_NAME, null, VERSION);
    }

    @Override
    public void onCreate(SQLiteDatabase db) {

        db.execSQL(CREATE_TABLE_PERSONS);
      
    }

    @Override
    public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
      
        db.execSQL("drop table if exists persons");     
       
        db.execSQL(CREATE_TABLE_PERSONS);
       
    }

    public DBHelper instance;

    public void closeDB() {
        super.close();
    }
}

二：建立工具类PersonDao

public class PersonDao {
    private static final String TAG = "PersonDao";
    Context context;
    SQLiteDatabase db;

    public PersonDao(Context context) {
        this.context = context.getApplicationContext();
        //再此自动创建表
        db = new DBHelper(context).getWritableDatabase();
    }

    public void updateOrInsert(Person person, String caseId) {
        ContentValues values = new ContentValues();
        values.put("caseId", caseId);
        values.put("case_member_id", person.getCase_member_id());
        values.put("truename", person.getTruename());
        values.put("sex", person.getSex());
        values.put("mobile", person.getMobile());
        values.put("occupation", person.getOccupation());
        values.put("birthday", person.getBirthday());
        values.put("paper_type", person.getPaper_type());
        values.put("paper_num", person.getPaper_num());
        values.put("employer", person.getEmployer());
        values.put("address", person.getAddress());
        values.put("role", person.getRole());
        values.put("relation_member_id", person.getRelation_member_id());
        values.put("type_name", person.getType_name());
        values.put("licence_type", person.getLicence_type());
        values.put("licence_num", person.getLicence_num());
        values.put("user_id", person.getUser_id());
        values.put("prohibition", person.getProhibition());
        values.put("hxId", person.getHxId());

        int r = db.update("persons", values, "caseId=? and case_member_id=?", new String[]{caseId, person.getCase_member_id() + ""});
        if (r > 0) {
            L.e("person更新成功：" + values);
            db.close();
        } else {
            values.put("prohibition", 1);
            long x = db.insert("persons", null, values);
            if (x > -1) {
                L.e("person插入成功：" + values);

            }
            db.close();
        }
    }

    public Person queryOnePerson(String caseId, String user_id) {
        Person person = null;
        Cursor cursor = db.query("persons", null, "caseId=? and user_id=?", new String[]{caseId, user_id}, null, null, null);
        while (cursor.moveToNext()) {
            person = new Person();
            person.setCase_member_id(cursor.getInt(cursor.getColumnIndex("case_member_id")));

        }
        cursor.close();

    }

    public ArrayList queryPersonByCaseId(String case_id) {//这个地方有bug，这样查询会查询出来很多个person，并且每个person会在不同的案件中有不同的身份

}

四:插入数据库:

 //把原告代理人信息存入数据库
                        Person person = new Person();
                        person.setCase_member_id(accuserAgentBean.getCase_member_id());
                        person.setTruename(accuserAgentBean.getTruename());
                        person.setSex(accuserAgentBean.getSex());
                        person.setMobile(accuserAgentBean.getMobile());
                        person.setOccupation(accuserAgentBean.getOccupation());
                        person.setBirthday(accuserAgentBean.getBirthday().toString());
                        person.setPaper_type(accuserAgentBean.getPaper_type());
                        person.setPaper_num(accuserAgentBean.getPaper_num());
                        person.setEmployer(accuserAgentBean.getEmployer());
                        person.setAddress(accuserAgentBean.getAddress());
                        person.setRole(accuserAgentBean.getRole());
                        person.setRelation_member_id(accuserAgentBean.getRelation_member_id());
                        person.setType_name(accuserAgentBean.getTruename());
                        person.setLicence_type(accuserAgentBean.getLicence_type());
                        person.setLicence_num(accuserAgentBean.getLicence_num());
                        person.setUser_id(accuserAgentBean.getUser_id());
                        person.setHxId(accuserAgentBean.getHx_account());
                        PersonDao personDao = new PersonDao(getActivity());
                        person.setProhibition(0);
                        personDao.updateOrInsert(person, case_id + "");

五:查询数据库:

  //查询表里是否有数据
  final ArrayList persons = personDao.queryPersonsByCaseId(case_id + "");
  if (persons.size() != 0) {
    //有数据
   }
