Question

How can I make the following sql statement part of the “SET” in my query? I want to pull out a list in a column and have my “SET” run against that. That way my “SET” isn’t just one variable but rather a list to run against. Make sence?

DECLARE @Item as char(32)
declare @result varchar(max);
SET @Item = '034100-3JK'; 

I want to use something like the following to have it query against instead of the 034100-3JK:

select distinct
        a.t_sitm as StartItem
from 
        ttibom010101 as a 
        INNER JOIN ttiitm001101 as b on a.t_sitm = b.t_item 
where 
        b.t_ctyp != 'TOP'
        and b.t_ctyp != 'SUB'

EDITED: Based on asker’s comments

I noticed that you are explicitly writing out the item code (or ID, whatever you want to call it). If you have a static list of codes that cannot be easily retrieved from your database, you can do something like this:

DECLARE @Items TABLE
(
  item varchar(10)
)
INSERT INTO @Items
VALUES ('034007-3CL'),
('next_code'),
('next_next_code')

Alternatively, if that list of codes can be grabbed easily:

DECLARE @Items TABLE
(
  item varchar(10)
)
INSERT INTO @Items
SELECT a.items
FROM mytable AS a
WHERE a.column = condition

Then you can use the variable like a normal table:

select 
   a.t_sitm as StartItem
   ,a.t_mitm
   ,a.t_sitm
   ,b.t_ctyp
   ,a.t_qana
from 
   ttibom010101 as a 
   INNER JOIN ttiitm001101 as b on a.t_sitm = b.t_item 
   INNER JOIN @items as c on a.t_sitm = c.item
where 
   b.t_ctyp != 'TOP'
   and b.t_ctyp != 'SUB'
