ExecuteNonQuery（）不会在C＃和SQL Server数据库中返回受影响的行

Question

I'm using SQL Server 2008 and Visual Studio 2010. The issue happen when using ExecuteNonQuery() command. In most cases, it returns the real number of rows affected, but when I tried to delete a group of records, it returns 0.

When I opened the table in SQL Server Management Studio, I see 33 records were deleted.

This is my code:

sqlQuery = "delete from  priv_  where user_id=" + txt_id.Text;
cmd = new SqlCommand(sqlQuery, con);
MessageBox.Show("rows affected = " + cmd.ExecuteNonQuery());

The message box show

rows affected = 0

When I use the same query in SQL Server Management Studio, it shows

33 rows affected

I have change the ONCOUNT to off, but nothing change.

I was experiencing this problem for few weeks.I had a problem with the login rights that I was using for the database. I was able to run queries but not from my application and it does not throw any error. So I added the 'owner' rights to the login in SQL Server 2014 under

My_server->Security->logins->My_login->Properties->User Mappings->My_database->Select appropriate rights
