The standard says that a BOOLEAN may be one of the following literals:
TRUE
FALSE
UNKNOWN or NULL (unless prohibited by a NOT NULL constraint)
the boolean values in any sane boleean system are True or false , noooh sql should have other values so you should check them for the not NULL values , more work for nothing
Today i saw this nice firebird hosting company and i want to share it (it's an very good idea to follow and to create an Firebird+LAP hosting company)
There are many Linux hosting companies, many LAMP (Linux/Apache/MySQL/PHP) environments. But we offer MORE! We offer the Firebird SQL database, Perl and Python scriping languages, FTP and direct shell access, and now Mono, a free implementation of Microsoft's .NET framework! Now you can put put your sites together with VB.NET and C#, but still run on the most popular web server platform.
