I have a team group parameter in my SSMS stored procedure. The team group parameter has 4 values. So far this is what I've coded:

SQL

Declare
 @Param1 int = 1
,@Param2 varchar(4) = '1169'
,@TeamGroup varchar(150) = 'RCBE,RLEG,RPEN,RSPC'

-- Code below supports multi-select in report

if OBJECT_ID('Tempdb..#TeamGroups','U') is not null
   drop table #TeamGroups
CREATE TABLE #TeamGroups
(TeamGroupKey varchar(100))
INSERT INTO #TeamGroups
SELECT value FROM HEA.Parselist(@TeamGroup,',')

I later join my #Teamgroups table to my main query. My question then: is it possible to use a case statement when I create my Temp table, so that I can include a select all or exclude all value? Or should I approach this differently?

What I have tried:

I've researched MSDN parameters as well as how to modify them.

There are many ways to do it; however, one easy way would be to do something like this:

SQL

SELECT value FROM HEA.Parselist(@TeamGroup, ',')
UNION 
SELECT team
FROM TeamGroups
WHERE @TeamGroup = 'All'

That would union in all your teams if @TeamGroup was a keyword of "All"
