Subject RE: How to update multiple rows
Date Tue, 11 Nov 2003 21:02:31 GMT
If I´m not mistaken (haven´t used update much), the clauses that go in
the WHERE part are those that take a SqlEnum argument

so in your example, the code generates:

UPDATE PRICE = 0, AUTHOR = 'ME' WHERE ID>100

please correct me if I´m wrong
