SHOW MATERIALIZED VIEWS

SHOW MATERIALIZED VIEWS
Syntax
SHOW MATERIALIZED VIEWS [IN/FROM schema_name] [WITH TABLES LIKE pattern]
Description
This statement is used to list all materialized views whose catalogName is mv and corresponding data tables. If you want to view only the MVs in a schema, use the [IN/FROM schema_name] clause.
The LIKE clause is used to filter views whose names meet the regular expression. If this clause is not used, all views are listed. The matched views are sorted in alphabetic order.
Currently, the regular expression supports the following matching rules: asterisk (*) or percent sign ( %) for matching any character, underscore (_) for matching one character, and vertical bar (|) for connecting two or more conditions.
Example
