Subject RE: How to update multiple rows
Date Tue, 11 Nov 2003 20:58:31 GMT
Hey

I am also new to Torque and have a simple question. From what you described, using the book
example, would the criteria objects for those two UPDATE statements be the same?

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

Criteria c = new Criteria();
c.add(BookPeer.BOOK_PRICE, 0);
c.add(BookPeer.AUTHOR, "ME");
c.add(BookPeer.BOOK_ID, 100, Criteria.LESS_THAN);
BasePeer.doUpdate(c);

Thx

The criteria is just a hashtable extension to store all the mappings,
later on, when calling the methods, the SQL generator knows where to
insert them ( if you are lucky ;) )
