Checking for @@ERROR after a SELECT inside a transaction?

Is it normal practice to check for @.@.ERROR after a SELECT statement that retrieves data from a table OR we should only check for @.@.ERROR after a DELETE/INSERT/UPDATE type of statement?The SQL statement is inside a transaction.SELECT statements can return an error. Just do a find on this page for "error".
