How to ignore a parameter in stored procedure if its value is null

Question

I have a stored procedure in which I have to join 10 tables and use WHERE condition to filter the records based on the parameters passed in the stored procedure

Answer 1

You just need to give the parameters which are being used.

If only value for Var1 needs to be passed.

proc1 @Var1 = Var1Value

If the value for Var6 needs to be passed.

Proc1 @Var6 = Var6Value

Please use case in this like

 where case @var1 when null then 1 else  a.id end =  case @var1 when null then 1 else  @var1 end 

Hope this will help you Thanks
