SQL (Structured Query Language)
is a widely used language for quering relational databases. The code in this
archive is addressing real life tasks like generating sales statistics,
calculating next birthday of employee and so on, using Transact-SQL, MySQL and
Jet-SQL syntax. Most of the scripts reference the
"Colombo Ltd" database. This is a sample database with some business data
in it. As for the standards, most of the features discussed are part of the
SQL-89, SQL-92 specifications and few are from those introduced in SQL-99.
This archive stores a lot of sql samples usefull for learning sql programming

tutorial for beginners. If you need one, go to:
