Update Top n Records

Hello Experts,

I have a table (tblReg) that I wish to Update a field named "flag" to Yes. I only want to Update the TOP 100 records. I realize that the property Top Values is available only for a Select query not available for an Update query.

How can I simply Update this field from No to Yes with the criteria being only the first 100 records?
It does not matter which records, just 100 of them.

Thanks    
Jim

I'd try something like this...

(replace someField with a unique id column-name and orderField by the field you want to order by for the TOP)

UPDATE tblReg SET Flag=True WHERE tblReg.someField IN (SELECT TOP 100 someField FROM tblReg ORDER BY orderField)

Create a TOP 100 Select query first to limit the recs, then ... create a Update query that Joins on that query - so that only 100 recs will be affected.  Or, use a WHERE clause with the IN operator to 'join' on that query.

Thanks. Have not used a WHERE  IN statement. Thanks for spelling in out.
