SHOW SCHEMAS
Applies to: 
Databricks SQL Databricks Runtime
Lists the schemas that match an optionally supplied regular expression pattern. If no pattern is supplied then the command lists all the schemas in the catalog.
While usage of SCHEMAS and DATABASES is interchangeable, SCHEMAS is preferred.
Syntax
SHOW SCHEMAS [ { FROM | IN } catalog_name ] [ [ LIKE ] regex_pattern ]
