任何人都可以帮助我：android.database.sqlite.SQLiteException：靠近“，”：语法错误（代码1）：，

Question

Please solve my problem: This is the code line

Cursor cursor = db.rawQuery("select * from Overhead_Table where IDNO="+incomingrecord[0]+" AND DATE_TIME LIKE "+DTTIME+"%" ,null);

I Also tried:

Cursor cursor = db.rawQuery("select * from Overhead_Table where IDNO=? AND DATE_TIME LIKE ?%" ,new String[] {incomingrecord[0],DTTIME});

and

Cursor cursor = db.rawQuery("select * from Overhead_Table where IDNO=? AND DATE_TIME LIKE ?" ,new String[] {incomingrecord[0],DTTIME+"%"});

But it shows error

android.database.sqlite.SQLiteException: near ",": syntax error (code 1): , while compiling: select * from Overhead_Table where IDNO=6765456765 AND DATE_TIME LIKE 14,01,2021

Answer 1

Always use ? placeholders:

String sql = "SELECT * FROM Overhead_Table WHERE IDNO = ? AND DATE_TIME LIKE ? || '%'";
Cursor cursor = db.rawQuery(sql , new String[] {incomingrecord[0], DTTIME});

I assume that both incomingrecord[0] and DTTIME are strings.
