Do you every read ISO Standards and know not to use "tbl" affixes?

UPDATE Products
SET isactive -- assembly lamnguage flag in SQL !!!
= NOT isactive
WHERE product_id = 123;

DUH!! If you had bothered to read ANY SQL book before posting, you
would know we have no Boolean data types in SQL. If you had a better
education in math or RDBMS, you would know why.


Newsgroups are a bad place to get a basic education. We will give you
kludges to get rid of you because of your stupid questions, but they
will not make you a good programmer.
