SHOW MATERIALIZED VIEWS
语法
SHOW MATERIALIZED VIEWS [IN/FROM schema_name] [WITH TABLES LIKE pattern]
描述
列出catalogName为mv中的所有物化视图以及对应的数据表。如果希望只查看某个schema中的物化视图，可以使用子句[IN/FROM schema_name]
通过可选子句“LIKE”，筛选视图名满足规则运算表达式的视图，如果不使用这个子句，会列举所有视图。匹配的视图会按字母顺序排列。
目前规则运算表达式支持“*”或“%”用于匹配任何字符，下划线“_”用于匹配一个字符，或“|”用于条件连接两个或多个条件。
