SHOW VIEWS

Returns all the views for an optionally specified schema. Additionally, the output of this statement may be filtered by an optional matching pattern. If no schema is specified then the views are returned from the current schema. If the specified schema is the global temporary view schema, Databricks Runtime lists global temporary views. Note that the command also lists local temporary views regardless of a given schema.

Syntax

SHOW VIEWS [ { FROM | IN } schema_name ] [ LIKE regex_pattern ]

Parameters

  • schema_name

    The schema name from which views are listed.

  • regex_pattern

    The regular expression pattern that is used to filter out unwanted views.

    • Except for * and | character, the pattern works like a regular expression.

    • * alone matches 0 or more characters and | is used to separate multiple different regular expressions, any of which can match.

    • The leading and trailing blanks are trimmed in the input pattern before processing. The pattern match is case-insensitive.

Examples

-- Create views in different schemas, also create global/local temp views.
> CREATE VIEW sam AS SELECT id, salary FROM employee WHERE name = 'sam';
> CREATE VIEW sam1 AS SELECT id, salary FROM employee WHERE name = 'sam1';
> CREATE VIEW suj AS SELECT id, salary FROM employee WHERE name = 'suj';
> USE SCHEMA usersc;
> CREATE VIEW user1 AS SELECT id, salary FROM default.employee WHERE name = 'user1';
> CREATE VIEW user2 AS SELECT id, salary FROM default.employee WHERE name = 'user2';
> USE SCHEMA default;
> CREATE TEMP VIEW temp1 AS SELECT 1 AS col1;
> CREATE TEMP VIEW temp2 AS SELECT 1 AS col1;
