我在android中使用sqlite,我通过传递多个where子句来获取结果,这给了我一个错误。单个 where 子句对我来说很好,问题是多个 where 子句。请向我建议更改或找出我正在做的错误
带有查询的错误消息
ERROR/AndroidRuntime(837): Caused by: android.database.sqlite.SQLiteException:

WHERE r_state = Maharashtra AND r_city = Thane AND r_region = Checknaka
String selection = MySQLiteHelper.STATE + " = Maharashtra"
+" AND " + MySQLiteHelper.CITY + " = Thane"
+" AND " + MySQLiteHelper.REGION + " = Checknaka";
Cursor cursor = database.query(MySQLiteHelper.RETAILER_TABLE,
new String[] {MySQLiteHelper.COLUMN_ID, MySQLiteHelper.SHOP }, selection,
null, null, null, null);
