Delete (SQL)

In the database structured query language (SQL), the DELETE statement removes one or more records from a table. A subset may be defined for deletion using a condition, otherwise all records are removed. Some DBMSs, like MySQL, allow to delete rows from multiple tables with one DELETE statement (this is sometimes called multi-table DELETE).

Usage

The DELETE statement follows the syntax:

Any rows that match the WHERE condition will be removed from the table. If the WHERE clause is omitted, all rows in the table are removed. The DELETE statement should thus be used with caution.

The DELETE statement does not return any rows; that is, it will not generate a result set.

Executing a DELETE statement can cause triggers to run that can cause deletes in other tables. For example, if two tables are linked by a foreign key and rows in the referenced table are deleted, then it is common that rows in the referencing table would also have to be deleted to maintain referential integrity.

Examples

Cyberchase

Cyberchase is an American–Canadian animated television series that premiered on January 21, 2002, on PBS Kids.

The series focuses around three Earth kids, Jackie, Matt, and Inez, who are brought into Cyberspace, a digital universe, to protect it from the evil Hacker. Using math in application with problem-solving skills, environment and weather, they are able to prevent Hacker from causing any more harm. In Cyberspace, they meet Digit, a cybird that helps the kids on their mission to save Cyberspace.

The series was created by Thirteen. In July 2010, after the season eight finale, PBS Kids put Cyberchase on hiatus for unknown reasons, but on their official Facebook page, Cyberchase announced the return of the show with a new season that premiered on November 4, 2013.

On February 10, 2015, Gilbert Gottfried, the voice of Digit, announced that five new season 10 episodes were expected to be broadcast in the latter half of 2015. Season 10 premiered on November 9, 2015.

Premise

When three average Earth kids, Jackie, Matt, and Inez accidentally allow the Hacker access to Motherboard, the supreme ruler of Cyberspace, she becomes severely weakened by a virus. The kids are brought into Cyberspace in an effort to protect the world from the Hacker and his clumsy assistants Buzz and Delete until a cure is found. They join forces with Digit, and later many more Cybercitizens that turn out to be great friends who are willing to fight for Motherboard.
