About Update

The Update statement is a Structured Query Language statement which is used to change or update values in a table. It is usually suffixed with a WHERE clause to restrict the change to a set of values that meet a specific set of criteria. For Update a table the username must be granted the privilege to do so by the database administrator. Even while using an application, when data is changed (like Andrew Smith’s email address above), the application is really sending the equivalent Update statement like the one above to execute on the database. This definition was written in the context of SQL.
