Question

I have a WHERE-clause in my SQL-query, and would like to add an argument depending on if the @Fran variable is set.

If @Fran is NULL, then it shouldn’t filter the results at all. Otherwise, if @Fran is set, then it should add a WHERE clause “AND franid=@Fran”. How could i do that?

Answer 1

SELECT ...
FROM ...
WHERE ...
AND ((@Fran IS NULL) OR (@Fran IS NOT NULL AND franid=@Fran));
