Concepts to be Known

Details on Users Privileges

Throughout this article, some English terms related to user privileges will come up often. We invite you to refer to the table below to understand their meaning.

ALTER ROUTINEModify the definition of a routine, that can be an aggregate function, a normal function or a procedure. Routines are SQL objects that allow defining a logic to apply to data.
CREATEDefine a table (CREATE TABLE), a new database (CREATE DATABASE), etc.
CREATE ROUTINEGroup stocked functions and procedures. 
CREATE TEMPORARY TABLESCreate a temporary table. A temporary table exists only in the session that created it. 
CREATE VIEWDefine a view. A view is a virtual table; in other words, it is a table whose data are not stored in the database, and containing informations from many tables.

EVENTAllow to obtain data to monitor or solve problems in SQL.

REFERENCESThe reference permission on a table allows to create a foreign key that refers to this table; this way, administrators can perform required modifications without having to take into account the needs of the persons to whom the table has been referenced.
