java - 从 sqlite 表中删除一行

Question

我正在从 sqlite 表中删除一行，并且在我做错的地方没有删除行，请建议我。

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

Answer 1

尝试这个：

 //---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);
    }

Answer 2

也许您的 EmergencyTable 或 colID 是错误的......
