Any ideans on how or if I can actually use a case statment in this respect:

INNER JOIN dbo.ufnTopEmpIdentification(null,@EDICreateDate) ei on ei.personid = p.personid
AND ei.EmpCatId IN (CASE WHEN @PRCycleTypeCode IN ('NB','SB') THEN ('1') ELSE ('2,3') END )

Throws this error:
Syntax error converting the varchar value '2,3' to a column of data type int.

I did try using integers instead of characters, i.e.
(CASE WHEN @PRCycleTypeCode IN ('NB','SB') THEN (1) ELSE (2,3) END )

The ELSE part can only return 1 value.

[code]INNER JOIN dbo.ufnTopEmpIdentification(null,@EDICreateDate) ei on ei.personid = p.personid
WHERE CASE
WHEN @PRCycleTypeCode IN ('NB','SB') AND ei.EmpCatId IN (1) THEN 1
WHEN @PRCycleTypeCode NOT IN ('NB','SB') AND ei.EmpCatId IN (2, 3) THEN 1
ELSE 0
END = 1[/code]

or use simple if else


IF @PRCycleTypeCode IN ('NB','SB') 
    SELECT.....
    INNER JOIN dbo.ufnTopEmpIdentification(null,@EDICreateDate) ei on ei.personid = p.personid
    AND ei.EmpCatId IN (1)
ELSE 
    SELECT.....
    INNER JOIN dbo.ufnTopEmpIdentification(null,@EDICreateDate) ei on ei.personid = p.personid
    AND ei.EmpCatId IN (2,3)
