Question

I have a sql query that I run against a sql server database eg.

SELECT * FROM MyTable WHERE Id = 2

This may return a number of records or may return none. If it returns none, I would like to alter my sql query to return a default record, is this possible and if so, how? If records are returned, the default record should not be returned. I cannot update the data so will need to alter the sql query for this.

Answer 1

Another way (you would get an empty initial rowset returned);

SELECT * FROM MyTable WHERE Id = 2
IF (@@ROWCOUNT = 0)
   SELECT ...
