  HI

  I need a store procedure to filter the records that I return from the DB but i dont want to write a Different sql statement for each condition

  for example if i want to filter by 2 variables I DONT WANT THE SP BODY TO BE:

  if(not var1 is null)

  select...from.. where field1=var1

  if(not var2 is null)

  select...from.. where field2=var2

  instead I want to insert the if else into the where part of the sql, something like:

  select.. from.. if (not is null var1) where field1=var1...

  Is it possible ???

  I Have something that almost work:

  select...from...

  WHERE (Field1= CASE WHEN @Var1 IS NULL  THEN Field1  ELSE @Var1 END) 

  but it dosent work if field1 is null, in this case instead of getting all the records I Get none.
