Here's an example of my current sproc:

Hiya,

I have inserted a definition for a view in $template_dir/sql/$someTableName.sql file. (create or replace view) so every time I run syncdb, the db views are created.

I'm trying to create a view where I want a column to be only true or false. However, it seems that no matter what I do, SQL Server (2008) believes my bit column can somehow be null.
I have a table called "Product" with the column "Status" which is INT, NULL. In a view, I want to return a row for each row in Product, with a BIT column se...

To this end, I'm trying to create a view of my Users table that excludes the plaintext passwords and instead provides a hashed value of that password.
Here's my current SQL Serv...
