Hello,
    I have a query which pulls contact data from accounts that a salesman has and also includes sales and profit data from the prior year. This works fine, except if the account had no activity in 2012 (or no entry for 2012 in the arcsales table) then it doesn't pull any data for that account. I need it to pull the contact info regardless if there is Sales and Profit info. I've been told I need to check for null fields for T3.YTDTotSales and
  T3.YTDPubProfit but I am ubsure how to do this.

SELECT
  T.CustAcct,
  T.CustomerName,
T.Address1,
T.Address2,
  T.City,
  T.State,
  T.Zip,T3.YTDTotSales,
  T3.YTDPubProfit
  T1.FirstName As SalesContactFirstName,
  T1.LastName As SalesContactLastName,
T1.EmailAddress,
  T2.SmanCode As SmanCode,

FROM arcusts T
  Left Outer Join arcconts T1 On T.SalesContactID = T1.CustContactID
  Left Outer Join arsmen T2 On T.SmanID = T2.SmanID
  Left Outer Join arcsales T3 On T.CustID = T3.CustID
WHERE T3.FiscalYear=2012
and T2.SmanCode='Salesman1'

putting the conditions in the where clause effectively turns your outer joins into inner joins

try keeping them in the join clause


SELECT
  T.CustAcct,
  T.CustomerName,
T.Address1,
T.Address2,
  T.City,
  T.State,
  T.Zip,T3.YTDTotSales,
  T3.YTDPubProfit
  T1.FirstName As SalesContactFirstName,
  T1.LastName As SalesContactLastName,
T1.EmailAddress,
  T2.SmanCode As SmanCode,

FROM arcusts T
  Left Outer Join arcconts T1 On T.SalesContactID = T1.CustContactID
  Left Outer Join arsmen T2 On T.SmanID = T2.SmanID
  Left Outer Join arcsales T3 On T.CustID = T3.CustID
                           and T3.FiscalYear=2012
                           and T2.SmanCode='Salesman1'

what do you mean by "check for null values"

if you find them, what do you want to do?
you can use  

     and some_column is null    

in the where clause or join conditions if you want to look for nulls
or something like

     isnull(t.custacct,' null account')  as custacct,  

to replace nulls with a value in the select
