Need help pulling data will NULL fields from MS SQL query.
Posted on 2013-01-10
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.

putting the conditions in the where clause effectively turns your outer joins into inner joins
try keeping them in the join clause

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
