Question

Having this where clause :

The first and second placeholder ? can have values : 1 || NULL
The third place holder is dynamically added (array)

IF(ISNULL(?),1,xy.id) IN 
     (IF(ISNULL(?),1,(SELECT x.id FROM x WHERE name IN (?))))   

I need this type isnull checking because i want the clause to always return true if data sent is null. Basically if data is null clause will be 1 IN 1 , if its not null find the corespondent ids , but if() function limits me to return only 1 result (not a set) .What options do i have here except dynamically build the whole query in php ?

Answer 1

You can do this in your where clause

WHERE (ISNULL(?) OR xy.id IN (SELECT x.id FROM x WHERE name IN (?)))
