[MySQL+PHP] SELECT -> Ignore condition if zero rows?

Posted on 2011-03-04

Hi,

I have this example mysql_query:

mysql_query("SELECT * FROM table WHERE id='$id' AND name NOT IN($names)");

Is there any option in mysql_query to get results even if this returns Zero rows, i.e. run query ignoring that second condition?

I know it's easy to use PHP if() but I'm just curious whether is possible to do it inside one mysql_query.

Thanks for ideas!

you could do this:
mysql_query("SELECT * FROM table WHERE id='$id' AND ( name NOT IN($names) OR NOT EXISTS(  SELECT * FROM table WHERE id='$id' AND ( name NOT IN($names))  ))");
