sqlite-Android SQLite查詢報錯

Android SQLite查詢報錯

在運行查詢語句時，報錯語法錯誤：

inal Cursor c = getContentResolver().query(
Provider.GAME_URI, new String[]{"CASE WHEN " +DBHelper.COLUMN_CRE_USER + " = " + preferences.getInt(LoginScreen.ID, 0) + " THEN (" + DBHelper.COLUMN_CRE_PTS + " AS you AND " + DBHelper.COLUMN_CON_PTS + " AS them) ELSE (" + DBHelper.COLUMN_CON_PTS + " AS you AND " + DBHelper.COLUMN_CRE_PTS + " AS them)"},"turn = ?",
new String[] { preferences.getInt(LoginScreen.ID, 0) + ""}, null);

報的錯：

04-24 19:57:48.345: E/AndroidRuntime(18775): Caused by: android.database.sqlite.SQLiteException: near "AS": syntax error (code 1): , while compiling: SELECT CASE WHEN createduser = 112 THEN (createdplayerpts AS you AND connectedplayerpts AS them) ELSE (connectedplayerpts AS you AND createdplayerpts AS them) FROM game WHERE (turn = ?)

最佳回答：

類似這種SQL語法錯誤可以把你的語句先放到sql工具中執行下，首先確保sql語句本身沒錯，再檢查你的代碼有沒有筆誤，類似缺少逗號，括號不匹配這些。
