非常簡單的sqlite查詢「沒有這樣的列」

Question

這應該是一個非常簡單的任務，但我一直堅持一個小時。

我試圖在源碼瀏覽器此查詢，其WORKING：

SELECT name FROM msUser WHERE username='admin' AND password='admin' 

但是，當我在Java代碼中試過，它不是工作呢：

querySelect = "SELECT name FROM " + TABLE_NAME + " WHERE username = " + username + " AND password = " + password; 

這是什麼日誌貓說：

01-19 14:21:02.279: E/AndroidRuntime(3117): android.database.sqlite.SQLiteException: no such column: admin: , while compiling: SELECT name FROM msUser WHERE username = admin AND password = admin 

請幫助我，謝謝：d

Answer 1

試試這個：

querySelect = "SELECT name FROM " + TABLE_NAME + " WHERE username = '" + username + "' AND password = '" + password +"'";
