RE: Is this Impossible !!
Hi guys, Since speed is criteria is it faster to send Queries to the server in SQL or XML. If sent in XML we will have to parse it and then convert it into SQL again, which may slow down the process. > -----Original Message----- > From: Mark Birbeck [SMTP:Mark.Birbeck@i...] > Sent: Thursday, October 21, 1999 8:29 PM > To: xml dev mailing list > Subject: RE: Is this Impossible !! > > > > Hi everyone, > > Very busy so can't give you in depth on this, but I note that you are > using VB scripting so here is a bit of code from a VB script version of > our SOAP server. > > It's not that complicated, but it provides you with an easy way to create > a results set from any values.
