Thread: Display version
I've just figured out how to display the PostgreSQL version number in Cold Fusion. Here's the code: <CFQUERY NAME="getversion" DATASOURCE="yourdatasource"> SELECT version();</CFQUERY> <CFOUTPUT>#getversion.version</CFOUTPUT> Best regards, Frank Hilliard http://frankhilliard.com/
This seems like such a common place procedure that I figure there had to be a "right" way to do it. I've got two tables, orders and order_items. orders has a primary key "ordersid" and order_items has a foreign key, orderid (which obviously references orders.ordersid) Say I want to create a new order and put some items into it. If I use an autoincrement field I could just: INSERT INTO orders VALUES ( ... ); And then I need to get the orderid I just created to create new records in the orderitems table So am I supposed to immediately do a: SELECT ordersid FROM orders ORDER BY ordersid DESC LIMIT 1; And then get the value, and then do inserts in the order items table? Surely there's some way to wrap this all up into a nice little procedure or something.

Er, I usually just do this: select nextval('sequence'); insert into table(id_col) values (<nextval from above>); That way you are guaranteed a unique sequence value. You can also do this as: insert into table (all_columns_except_serial) values (whatever); > Thanks---- > > -Robby gh
