I need to join three tables. I want all 4 records from tableA and all matching records from tableB and tableC.  I end up with only 1 record.  In the end I only want 4 records and the data that matches.
SELECT   ui.ID, csct.description, csc.contact_type_acronym, csc.active, csc.date_added, ui.LastName + ', ' + ui.FirstName AS contactname, csct.acronym, csct.id as csctid
FROM         dbo.TableA AS csct LEFT OUTER JOIN   dbo.TableB AS csc ON csct.acronym = csc.contact_type_acronym 
LEFT OUTER JOIN dbo.TableC AS ui ON ui.ID = csc.contact_id
WHERE(csc.service_id = 196975) AND (csc.active = 1) AND (csct.ServiceLineID = '5') <-- this gives me the 4 records I need
ORDER BY csctid

Adding items to the where clause that are based on tables that are left joined basically results in an inner join on those columns.

If you move the 2 "csc.service_id = ..." and "csc.active = 1" clauses to the join portion, it should return the desired results.

SELECT   ui.ID, csct.description, csc.contact_type_acronym, csc.active, csc.date_added, ui.LastName + ', ' + ui.FirstName AS contactname, csct.acronym, csct.id as csctid
FROM         dbo.TableA AS csct LEFT OUTER JOIN   dbo.TableB AS csc ON csct.acronym = csc.contact_type_acronym and csc.service_id = 196975 and csc.active = 1
LEFT OUTER JOIN dbo.TableC AS ui ON ui.ID = csc.contact_id
WHERE  (csct.ServiceLineID = '5') <-- this gives me the 4 records I need
ORDER BY csctid

Hi,

Your problem cannot be the joins, the solution should be in the WHERE clause because you reference there

(csc.service_id = 196975) AND (csc.active = 1)

which don't belong to TableA csct ...

Do SELECT * and check manually the values to see it better.


Cheers
