    Posted: 21 September 2004 at 4:11pm
I am using MS Access Database. "Followdate" is a DATE field in this database. I want to search records where the date is less than any specified date.

Followdate=request.form("date")

sql = "select * from followquery where followdate<='" & followdate & "' "

I am getting this error

Microsoft JET Database Engine error '80040e07'
Data type mismatch in criteria expression.

Can body correct my Query.

Instead of quotation marks you use hash's (#) I think

I'm not an access guru but quotes may work around it, besides that always, always check your values before performins database operations. Use CDate(Followdate) to format it correctly and IsDate(Follwodate) as Boolean to make sure a valid date has been submitted.
If IsDate(followdate) Then
'Perform DB Operation
ELSE
Response.Write("not a date")
END IF

This should do the trick


Followdate=request.form("date")

if IsDate(followdate) then
sql = "select * from followquery where followdate<=#" & followdate & "# "
end if
