Hi Experts,
I am trying to figure out a strange Access/SQL behavior as follows.
I have a query that when displaying only 1 column it gives me one quantity of records and when displaying 2 columns it gives me a different qty.
Query1
SELECT DISTINCT TmpPatBillingCodes.PatientsID, #12/31/2013# AS Expr1
FROM TmpPatBillingCodes
WHERE (((#12/31/2013#) Between [effectivefrom] And [end]));

Open in new window

Query2
SELECT DISTINCT TmpPatBillingCodes.PatientsID, #12/31/2013# AS Expr1, TmpPatBillingCodes.EffectiveFrom
FROM TmpPatBillingCodes
WHERE (((#12/31/2013#) Between [effectivefrom] And [end]));

Open in new window

Can someone help me figure out?

You are using SELECT DISTINCT and if you have following table:
1 2
1 2
1 3

in first query (one column) result will be:
1
in second (two columns):
1 2
1 3

Remove DISTINCT and compare quantity of records
