Question

Needed to start a new thread to deal with a new issue from old problem.

Original problem is at this link….
complex query join checking that value does not exist

I have two tables, first has

Tb1 = drID, schedDate, rteID

Second has:

Tb2  = drID, FName, LName, Active

tb1 schedDate has a value for 11/12/2012 but returns no records, if I enter 11/01/2012 I get the correct records back, but this date does not exist on any record in tb1.

SELECT drID, Fname, LName
FROM   TB2
WHERE  Active = True 
AND   drID NOT IN (
      SELECT drID
      FROM   Tb1
      WHERE  (drID IS NULL OR drID = '')
      AND  (schedDate = (@targetDate)
      )

Both date fields are dates I have tried casting each individually and both together as in…

AND (CAST(schedDate AS DATE) = CAST(@targetDate AS DATE))

and

AND (CAST(schedDate AS DATETIME) = CAST(@targetDate AS DATETIME))

I am trying to check that no drID exists in tb1 on the date submitted.

Answer 1

This was the correct solution for this question….

WHERE not exists (SELECT drID FROM tb1 ....

Date values where not the issue.

Thanks for all of the feed back.
