Question

I am getting the error in the title when trying to do a simple search from a textbox through an SqlDataSource output to a gridview. If I search for 123 it returns the record with ID 123, as it should. If I search for aaa it returns the error. Anyone have any idea why??? The database looks like so:

id       int           (primary key / identity)
struser  nvarchar(50)

The SQL statement looks like this:

SELECT id, struser 
FROM ticket 
WHERE (id = @id) OR (struser = @struser)

Answer 1

Try

SELECT id, struser 
FROM ticket 
WHERE (CONVERT(VARCHAR,id) = @id ) OR (struser = @struser)
