SQL - Dates syntax ( VB6 connecting to SQL Server database)

Hi Experts

I'm trying to update a table with new [Test Requests]. It's in VB6, connecting to a SQL database and it's designed to select tests, requested after the [lastupdate] date. Just a syntax assist on the troublesome line.

eg
LastUpdate = "21/12/2009"

'select most recent tests
rs.CursorLocation = adUseClient
Sql = ""
Sql = Sql & " Select * from REQUESTEDTESTS "
'Sql = Sql & " where convert(varchar, [requestdate],120) > " .........datevalue(LastUpdate)??

'some examples of what i have tried

'/Sql = Sql & " where convert(varchar, [requestdate],120) > " & DateValue(LastUpdate) ' conversion failed
'/Sql = Sql & " where convert(varchar, [requestdate],120) > convert(varchar, [lastupdate],120)" 'invalid column
'/Sql = Sql & " where convert(varchar, [requestdate],120) > getdate(lastupdate)" 'doesn't work

rs.Open Sql, cn

Much appreciated.

try something like this...

sql = "Select * from YourTable where cast(requestdate as dateTime) > cast('" & LastUpdate & "',as Datetime)"

1/ Game-master
sql = "Select * from TESTREQUESTS where cast(requestdate as dateTime) > cast('" & LastUpdate & "',as Datetime)" ' ..........Syntax error near 'as' ( i have also tried placing a space between , and the second 'as')

2/ Sharath -
I changed it to ".........RequestDate > '" & LastUpdate & "'" and IT WORKED . Grateful for the help.

siThanks
