MySQL 8.0 Reference Manual  /  ...  /  The create_synonym_db() Procedure

27.4.4.1 The create_synonym_db() Procedure

Given a schema name, this procedure creates a synonym schema containing views that refer to all the tables and views in the original schema. This can be used, for example, to create a shorter name by which to refer to a schema with a long name (such as info rather than INFORMATION_SCHEMA).

Parameters
  • in_db_name VARCHAR(64): The name of the schema for which to create the synonym.

  • in_synonym VARCHAR(64): The name to use for the synonym schema. This schema must not already exist.
