Hi Pinal,

I am facing an issue with MS SQL 2000 inner joins. Though the systax is runnig fine in 2005 i.e, using “*” for outer joins. But same syntax raising error on 2000

Kindly suggest

Regards
Saubhagya

Hi Pinal,
I have a huge set of data that needs to be ported to another table. i have to port a single record at a time. Iam currently using a cursor to do the same. Can we go for OLE DB Command flow in SSIS? will it have advantage over cursor.
Could you please clarify this?

So when an inner join can be applied only on a primary key column / Foreign column , the Intersect can pull out the exact matching record based on the all the columns of the result set.Is that right?

this is working fine. but if I put

SELECT DISTINCT va.VendorID,va.ModifiedDate, *
FROM Purchasing.VendorContact vc
INNER JOIN Purchasing.VendorAddress va ON vc.VendorID = va.VendorID
AND vc.ModifiedDate = va.ModifiedDate

thn it fetches all the records.

please let me know what to do for this?

Hi Pinal/Dan/gabreil,

I have checked it and the problem came due to not fully installed SQL SERVER 2005.

So Thanks for your suggestion.

Thanks,

Jeetesh garg-

Check your compatablilty level. If you are running SQL Server 2005 in level 70 or 80, you could have similar behavior to what you are describing.

Hi Pinal,

Thanks for the post, now I think I prefer to Intersect/Except command, i feel comfortable with them than inner join.

Thanks,
Lekan

Jeetesh,

Your script works fine for me as well. Pinal has already posted screenshots for this example in post above.

I think you are not using SQL Server 2k5.
