Structured Query Language (SQL) is an ANSI (American National Standards Institute) Standard computer language. It is used to manage data stored in databases. Its basic functions are inputting, modifying, and deleting data from databases.
The video tutorial set provided below contains 135 videos. Each is designed for a discrete step in the SQL learning process.
Although SQL is an ANSI standard, there are many flavors of the SQL language availble. For each of these variations to be compliant with the ANSI standard, they must all support at least the major commands (such as SELECT, UPDATE, DELETE, INSERT, WHERE) in a similar way.
