What columns are "actually" pulled by the SQL?

In the SQL query, you can assign aliases to column names. This is probably the easiest method. I totally forget how to do this, but I'm sure google can help you out with it.

Giving a column an alias in the SQL statement is as simple:
SELECT user_id AS User FROM table_name

This will cause your dataset to populated with the data from user_id but the column will be called User in the dataset. You can do this for as many columns as you need in your SQL.

thanks guys, but do you think there's no other way to do it?

There's definetely other ways to do it. The solution proposed is the simplest, most elegant way I can think of.

You can always just enter whatever you want in the datagrid rows after the data is loaded. Don't remember off the top of my head how - I suspect theres a collection of cells (or a collection of rows with a collection of cells) that you could use to set the cell values. This would probably take a lot more effort than using the SQL method though....

datagridview1.column(0).headertext = "StudentID";
datagridview1.column(1).headertext = "Last Name";
