Im trying to use case to vary the value im checking in a where clause but I'm getting the error:

incorrect syntax near the keyword 'CASE'

SQL Server 2005

select * 
from   table
where  ((CASE when adsl_order_id like '95037%'
         then select '000000'+substring(adsl_order_id,6,6)
         ELSE select adsl_order_id
       END)
       not in (select mwebID from tmp_csv_dawis_bruger0105)

You could try

SELECT *
FROM table
WHERE (SELECT CASE WHEN adsl_order_id LIKE '95037%'
              THEN '000000' + SUBSTRING(adsl_order_id, 6, 6)
              ELSE adsl_order_id
              END)
      NOT IN (select mwebID from tmp_csv_dawis_bruger0105)

A correlated subquery is one possibility:

select * 
from mytable
where not exists (
    select * 
    from 
        tmp_csv_dawis_bruger0105
    where 
        mwebID = 
        CASE when mytable.adsl_order_id like '95037%' then '000000' + substring(mytable.adsl_order_id,6,6)
        ELSE mytable.adsl_order_id END
 )

You have one too many opening parentheses before the CASE expression.
