Help writing t-sql statement checking for a match in tables

I have two table.  Table 1 is called eventInformation and table 2 is called onlineOrder.  What I need to do is this.  I need a list of jobNumbers found in the eventInformation table that have a matching jobNumber in the onlineOrder table.  I wrote this...

SELECT     ei.jobNumber
FROM         eventInformation AS ei INNER JOIN
                      onlineOrder AS oo ON ei.jobNumber = oo.jobNumber AND ei.jobNumber = oo.jobNumber
                      AND ei.arrivalDate BETWEEN '01/01/2011' AND '12/31/2011'   

Open in new window


.. but I don't believe it's working.  Can someone tell me how I can fix my code in order for it to give me the results I'm looking for.

Thanks!

                      onlineOrder AS oo ON ei.jobNumber = oo.jobNumber AND ei.jobNumber = oo.jobNumber
                      AND (ei.arrivalDate >= '01/01/2011' AND ei.arrivalDate <= '12/31/2011')

Tried it... but it gives me the same result.  I'm reading about sub-queries.  Would a subquery work in my case?

You are correct in your subquery thought...
SELECT     ei.jobNumber
FROM         eventInformation AS ei
WHERE ei.jobNumber IN (SELECT jobNumber FROM onlineOrder)
