Hi. 

Thank you for your reply and the link. 

It definitely looks like a step towards solution but I checked the link and can't figure out how to change the query to make it work. 

Should I enter plain SQL replace function in it to replace Char(7) with comma? 

Here's what I have tried: 

UID_PersonHead IN (

    SELECT UID_Person 

    FROM Person

    WHERE

        CompanyMember IN (REPLACE(@CompanyParameter,char(7),','))

        AND PersonnelNumber NOT IN ('XXX', 'TEST')

)

What am I missing?

UID_PersonHead IN (

  SELECT UID_Person 

  FROM Person

  WHERE

    CompanyMember IN (select ParameterValue from dbo.QBM_FCVStringToList(@CompanyParameter,Char(7),0,1)) -- multivalue parameter

    AND PersonnelNumber NOT IN ('XXX', 'TEST')

)

Oh, ok, that did the trick! 

Thank you very much Mr. Markus Weiss-Ehlers, you saved my weekend!! 

PS: If you have any power over documentation providers, please send them this code-snippet, it will save a lot of time for everyone, I suppose. 

Thanks again, you rock! 

Have a nice day.
