Hi,

I'm trying to use if in mysql query, but can't get it work.

So the case is i want to select rows when siteid is not zero, if it's zero then I need to cancel the where.

I've tried

SELECT * FROM items WHERE IF(siteid > 0,$siteid,0) = $siteid

With this query I got good result when $siteid is not 0, but it returns empty when $siteid = 0, which actually select siteid = 0. What I need is no more where, so it should just returns all.

 

Could anybody help me here?

 

Thanks

You can either change your PHP code to just not include the WHERE clause if $siteid = 0 (better approach) or you could do as follows:

 

$query="SELECT *
FROM items
WHERE $siteid<>0 AND siteid=$siteid";
