Succeed in Using SQL

SQL (Structured Query Language) is a standard programming language used to query and manipulate the information held in a database. A query is a request to a database — to read information, write new data, update existing information, or delete records.

The most commonly used SQL statement is the SELECT statement, which reads data from a database. Clauses such as WHERE and ORDER BY let you filter and sort the data you retrieve.

These online lessons give you a start at using SQL, which is an essential skill in website development and database-driven applications such as ColdFusion.
