Question

I’m writing a small application using sqlite.
The debugger says that there is a syntax error.
I’ve tried But I couldn’t find where it is.

12-20 14:13:40.353: E/SQLiteLog(2329): (1) near ",": syntax error

SQLiteDatabase.rawQueryWithFactory(SQLiteDatabase$CursorFactory, String, String[], String, CancellationSignal) line: 1317
SQLiteDatabase.rawQuery(String, String[]) line: 1253
TemporaryDatabase.EntryGiris(int, String, int, int, int, int, int, int, int, int, int) line: 125

Here is the code:

public class TemporaryDatabase {
......

    String entryGirisSQL="SELECT "+C_ID
                        +" FROM harcamalar WHERE "+C_YIL+"="
                        +yilsql+","+C_AY+"="+aysql;
    Cursor  cursor=ourDatabase.rawQuery(entryGirisSQL, null);   
    int index=cursor.getColumnIndex(C_ID);
    if(index>=0)
        ourDatabase.update(DB_TABLE, cv, "c_id="+index, null);
    else ourDatabase.insert(DB_TABLE, null, cv);
  }

}

The problem is with your SQL query.

SELECT "+C_ID+" FROM harcamalar WHERE "+C_YIL+"="+yilsql+","+C_AY+"="+aysql;

SQL does not support commas as part of the WHERE clause. You need to use AND and OR to combine multiple expressions. Based on what you tried, I assume you want both to be satisfied. Therefore you should use AND.
