  • Artikkeli

Applies to: check marked yes Databricks SQL check marked yes Databricks Runtime 13.3 LTS and above check marked yes Unity Catalog only

Lists all the volumes accessible to the current user in the current or optionally specified schema. Additionally, the output of this statement may be filtered by an optional matching pattern.

Syntax

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

Parameters

  • schema_name

    Specifies the schema in which volumes are to be listed.

  • regex_pattern

    A STRING literal with a regular expression pattern that is used to filter the results of the statement.

    • 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.

Returns

A result-set with two columns:

  • database STRING NOT NULL: The schema of the volume
  • volumeName STRING NOT NULL: The name of the volume
