Question

試圖獲得一個查詢，但似乎並沒有work.It給出這個錯誤：

android.database.sqlite.SQLiteException: no such column: Gravity (code 1): , while compiling: SELECT club_id FROM Club WHERE club_name like Gravity 

這是代碼：

private String getClubCode(String clubName){ 
     open(); 
     Cursor mCursor = myDb.rawQuery("SELECT " + Table.Club.ID + " FROM " + Table.Club.TABLE_NAME + " WHERE " + Table.Club.NAME + " like " + clubName , null); 
     close(); 

     return mCursor.getString(mCursor.getColumnIndex(Table.Club.ID)); 
    } 

Answer 1

投入額外「之前和之後clubName：

Cursor mCursor = myDb.rawQuery("SELECT " + Table.Club.ID + " FROM " + Table.Club.TABLE_NAME + " WHERE " + Table.Club.NAME + " like '"+ clubName + "'" , null);
