Question

SQL Server 2005.

I have 2 lists:

1. (‘a’, ‘b’, ‘c’, ‘d’)

2. (‘d’, ‘e’, ‘f’, ‘g’)

I need to make a WHERE clause with these 2 inside a dynamic SQL string, something like:

 select *
 from tbl
 where ... afewconditionshere ...
      AND anyitemfrom[('a', 'b', 'c', 'd')] is inside [('d', 'e', 'f', 'g')]

it looks kinda weird, but I get this data from a 3rd party, cannot make too big changes

the lists would always have < 20 items inside

UPDATE

a,b,c,d,e,f,g are like security things not related to the table in any way, the idea is that if you have this anyitemfrom[(‘a’, ‘b’, ‘c’, ‘d’)] is inside [(‘d’, ‘e’, ‘f’, ‘g’)] then you are able to view the records returned, otherwise no records should be returned

yes this condition should basically return true or false

Answer 1

i figured it out

i used something like :

 CREATE TABLE #t (UserName VARCHAR(50))

 DECLARE @sql VARCHAR(MAX)
 SELECT @sql = 'INSERT INTO #t SELECT ''' + REPLACE(@UserList, ',', ''' UNION SELECT ''') + ''''
 PRINT (@sql)
 EXEC (@sql)

 SELECT * FROM #t

 IF OBJECT_ID('tempdb..#t') IS NOT NULL BEGIN DROP TABLE #t END

for both lists
then I was able to join them, and use the join’s recordcount
