Dynamic Enumeration

04-19-2004, 08:19 AM

I want to make a view that enumerates data dynamicly.. basicly

Select Blah, Identity as gennumber from tblFoo

which would return..

Blah | Number
A | 1
B | 2
C | 3
D | 4

how can this be done?

What view? MS SQL Server? I am not sure I am following you. Do you want to create something that is dynamic SQL? Such as, you want to pass the fields and table name to a DB object and have it run the query?

Sorry, its a MSSql Server Database. but I want to have a number field like an identity on a view that is created when I do a select.

I don't want to pass anything in. I just want a number that says its record 1,2,3,4,5,6 or whatever that is NOT the identity on the table but the number of the record as it exist in the view.

Well, you should be creating your View first. Basically in SQL Server (I am assuming that is what we are working with, if not, tell me) Do a CREATE VIEW statement that formats and brings in all the fields you want from the specified table. Then, you can query this View like another other table.

If you need to work with this imaginary record number in your VB code, you can use instead the recordset's AbsolutePosition property as a sort of record number. Or, you can just use a counter variable in thecode. I do not know how to do it server side if that is what you want, by adding in an impromptu autonumber-like field. Maybe look in Books On-Line for some sort of Transact-SQL function?

Hmm..well dealing with a View and the recordset object's AbsolutePosition property are two completely different things. I thought the question was in regards to creating a View and then enumerating it, looking for data.

Doh, seems like I made a few assumptions on his use of the enumeration. I really should wait to see what HE wants to do!!!
