Timothy writes "Hi,

I have to clean up a table with thousand of records that have erroneous dates. Specifically User entered the date, "2003-10-08" rather than 2004-10-08". What I need to do is upte the year from 2003 to 2004 leaving the month and day the same. Is there a way to accomplish this using the Update command?

All responses are most appreciated.

Thank you.

Timothy"

well initially i would say


Update yourTable
Set wrongDate = '2004-10-08'
From yourTable
Where wrongDate = '2003-10-08'
and wrongDate = wrong


The part in bold should be replaced by something that identitifies that the record is indeed wrong. Are they entries with '2003-10-08' that are correct? Etc....

update tbl
set dte = dateadd(yy,1,dte)
where datepart(yy,dte) = 2003


==========================================
Cursors are useful if you don't know sql.
DTS can be used in a similar way.

No leap year to worry about changing 2003 dates to 2004 - should there have been any records on 29th Feb 2004??
