SHOW TABLES (Databricks SQL)

Returns all the tables for an optionally specified database. Additionally, the output of this statement may be filtered by an optional matching pattern. If no database is specified then the tables are returned from the current database.

Syntax

SHOW TABLES [ { FROM | IN } database_name ] [ LIKE regex_pattern ]

Parameters

  • database_name

    Specifies database name from which tables are to be listed. If not provided, uses the current database.

  • regex_pattern

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

    • 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.
