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.

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.

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

try this if both requestdate and lastupdate are of datetime type.

 '/Sql = Sql & " where requestdate > lastupdate"

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.
