Default How to check whether query retuns some rows or not

Hello All Friends,
I am raj from New Delhi,India.
I am Developing a WebSite on ASP.Net Platform.Now I am executing a sqlQuery
"Select uid from tablename where uid='" + txtuid.Text + "'"

I wanna check whether this Query returns result or returns blank.
I can do this with inserting records in DataTable and then counting the rows in DataTable.
But is there any other way of doing this without DataTable or DataSet.
Thanks........raj

What are you going to use to hold the data?

Before you actually run the query you can run another query like:
"Select Count(*) from tablename where uid='" + txtuid.Text + "'"

You can return the count into a variable and check if it is >0.
