Need to do an SQL select statement in Classic ASP for a variable

I need to replace a session variable with the results of an SQL statement
that statement essentially is:
SELECT EmailAddress FROM USERS WHERE UserID=session(userid)"

Open in new window


My code is currently:
dim paypalnew as string = "SELECT EmailAddress FROM USERS WHERE UserID='"&session(userid)&"'"	
session("paypalemail")=paypalnew

Open in new window


However I am getting an error at "as"

I tried doing paypalnew=thestring but it put it as straight text instead of being a SQL Statement.

This is my first real programming project, so i know that i am probably just missing some basics, but finding resources for classic ASP is very tough :/

There are no datatypes in VBA other then variants so all variables are just defined like

Dim myVariableName

and to set a value to it :

Set myVariableName = 'whatever'

so your code would become :

dim paypalnew 
set paypalnew = "SELECT EmailAddress FROM USERS WHERE UserID='"&session(userid)&"'"	
session("paypalemail")=paypalnew

Open in new window


However you code will not achieve you desired result (as I understand it) of populating the session variable with the result of the query it will just populate it with the text.

In VB you do not have to dim your vars unless you have Option Explicit ON. Personally I never use it. I just pay attention to my vars and make sure I don't use the same name twice.

Not sure how much code you have versus what you're showing us, but you're missing some  basics so here's how I would do it...

SQL_Conn_STRING = "Driver={SQL Server};Server=MyServerName;Database=MyDBName;uid=MyUsername;pwd=MyPassword"
Set Con = Server.CreateObject("Adodb.Connection")
Con.Open SQL_Conn_STRING

set rs  = Con.Execute("SELECT Top1 EmailAddress FROM USERS WHERE UserID='"&session("userid")&"'")	
If NOT rs.EOF then
      paypalnew = Trim(rs("EmailAddress"))
      session("paypalemail")=paypalnew
Else
      ' No user found with this UserID
End if

Open in new window

Thanks when I get a shot next I will try this. I do have option explicit on though, not my idea, but working with it anyway.

Then just make sure to dim all your variables first before you use them.

That was perfect, the tutorials are terrific, but they don't tell me what is a variable and i was getting confused. I got it up and running now, so it is all good! Thanks Guys!
