SHOW DATABASES

Syntax

SHOW {DATABASES | SCHEMAS}
    [LIKE 'pattern' | WHERE expr]

Description

SHOW DATABASES lists the databases on the MariaDB server host.SHOW SCHEMAS is a synonym forSHOW DATABASES. The LIKE clause, if present on its own, indicates which database names to match. The WHERE and LIKE clauses can be given to select rows using more general conditions, as discussed in Extended SHOW.

You see only those databases for which you have some kind of privilege, unless you have the globalSHOW DATABASES privilege. You can also get this list using the mariadb-show command.

If the server was started with the --skip-show-database option, you cannot use this statement at all unless you have theSHOW DATABASES privilege.

The list of results returned by SHOW DATABASES is based on directories in the data directory, which is how MariaDB implements databases. It's possible that output includes directories that do not correspond to actual databases.

The Information Schema SCHEMATA table also contains database information.
