Hello,

I am writing a function that uses two table variables. The structures of
both are shown here:

DECLARE @workdates TABLE (
conflict CHAR(1),
workdate SMALLDATETIME
)

DECLARE @existing TABLE (
workdate SMALLDATETIME
)

I need to do an update on the first table:

UPDATE @workdates
SET conflict = 'X'
FROM @existing s
WHERE workdate = s.workdate

I am concerned that the unqualified 'workdate' in the WHERE clause will
give me an ambiguous column reference. Is this SQL statement valid?

Thanks,
Andrew
