Passing parameter from Data Environment to Oracle ?

What is the syntax of passing parameter to oracle from VB-6 Data Environment
Designer.

I tried following:

Select * from mytable where InvNo=mInvNo <------ this works only with
Microsoft Access but not with oracle and sql server

I also tried putting @ before parameter name but could not succeed.
Select * from mytable where InvNo=@mInvNo


The parameter name is not listing in Data Environment Parameter Tab.

Any idea please ?

Best Regards,

Luqman
