SHOW DATABASES
Syntax
SHOW {DATABASES | SCHEMAS}
[LIKE 'pattern' | WHERE expr]
Contents
Description
SHOW DATABASES lists the databases on the MariaDB server host.
SHOW SCHEMAS is a synonym for
SHOW 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 global SHOW 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 the
SHOW 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.
Examples
SHOW DATABASES; +--------------------+ | Database | +--------------------+ | information_schema | | mysql | | performance_schema | | test | +--------------------+
SHOW DATABASES LIKE 'm%'; +---------------+ | Database (m%) | +---------------+ | mysql | +---------------+
