從sqlite表中刪除一行

Question

我從sqlite表中刪除一行並且行不在刪除我在做錯的地方 請給我建議。

public void deleteBName(String id) 
    { 
// TODO Auto-generated method stub 
     SQLiteDatabase db = this.getWritableDatabase(); 
     db.delete(EmergencyTable, colID + "=" + id, null); 
    } 

Answer 1

也許你EmergencyTable或colID是錯誤的....

Answer 2

試試這個：

//---deletes a particular title--- 
public boolean deleteTitle(String name) 
{ 
    return db.delete(DATABASE_TABLE, KEY_NAME + "=" + name, null) > 0; 
} 

-

public void deleteBName(String id) 
    { 
// TODO Auto-generated method stub 
     SQLiteDatabase db = this.getWritableDatabase(); 
     return db.delete(EmergencyTable, colID + "=" + id, null); 
    }
