我添加了2個新列到我的SQL lite數據庫中,但我得到一個SQL錯誤,因爲其中一個新列沒有被創建。我讀過類似錯誤的其他線程,並進行雙重檢查以確保我的拼寫正確。Android數據庫SQLite異常「表沒有列命名」錯誤
這個問題似乎在我的onCreate,因爲這是程序崩潰的地方,但我似乎無法弄清楚。我添加了Player_Number和Team列,但是Player_Number並沒有被創建,而是一個團隊。
這裏是我的代碼將對DBAdapter:
public class PlayerDbAdapter {
private static final String DATABASE_CREATE = "CREATE TABLE Players (_id integer primary key autoincrement, Player_Name text not null, Player_Position text not null, Player_Number text not null, Team text not null);";
private static final String DATABASE_NAME = "Score";
private static final String DATABASE_TABLE = "Players";
private static final int DATABASE_VERSION = 3;
public static final String KEY_BODY = "Player_Name";
public static final String KEY_ROWID = "_id";
public static final String KEY_TITLE = "Player_Position";
public static final String KEY_NUMBER = "Player_Number";
public static final String KEY_TEAM = "Team";
private static final String TAG = "PlayerDbAdapter";
private final Context mCtx;
private SQLiteDatabase mDb;
private DatabaseHelper mDbHelper;
public PlayerDbAdapter(Context paramContext)
{
this.mCtx = paramContext;
}
public void close()
{
this.mDbHelper.close();
}
public long createPlayers(String playerName, String playerPosition, String playerNumber, String team)
{
ContentValues localContentValues = new ContentValues();
localContentValues.put(KEY_BODY, playerName);
localContentValues.put(KEY_TITLE, playerPosition);
localContentValues.put(KEY_NUMBER, playerNumber);
localContentValues.put(KEY_TEAM, team);
try{
return this.mDb.insert("Players", null, localContentValues);
} catch (Exception e) {
Log.e("Juma", e.getMessage());
}
return 0;
}
logcat的

您創建查詢是錯誤的,你倒排表和表名 – njzk2
你有一個語法錯誤,如njzk2指出,使用:'CREATE TABLE玩家......'你也應該用你的靜態變量,比如'DATABASE_TABLE',以幫助防止錯別字。 – Sam
