Artikel ini berisi ALTER DATABASE
SQL sintaks, seperti yang diterapkan oleh berbagai sistem manajemen basis data (DBMS). Sintaksnya terdaftar persis seperti yang telah dicantumkan oleh setiap vendor di situs web mereka. Klik tautan yang berlaku untuk melihat detail selengkapnya tentang sintaks untuk vendor tertentu.
DBMS yang tercakup adalah MySQL, SQL Server, PostgreSQL, dan Oracle Database.
MySQL
Dari Manual Referensi MySQL 5.7:
ALTER {DATABASE | SCHEMA} [db_name
]alter_specification
... ALTER {DATABASE | SCHEMA}db_name
UPGRADE DATA DIRECTORY NAMEalter_specification
: [DEFAULT] CHARACTER SET [=]charset_name
| [DEFAULT] COLLATE [=]collation_name
SQL Server
Dari Referensi Transact-SQL:
ALTER DATABASE { database_name | CURRENT } { MODIFY NAME = new_database_name | COLLATE collation_name | <file_and_filegroup_options> | <set_database_options> } [;] <file_and_filegroup_options >::= <add_or_modify_files>::= <filespec>::= <add_or_modify_filegroups>::= <filegroup_updatability_option>::= <set_database_options>::= <optionspec>::= <auto_option> ::= <change_tracking_option> ::= <cursor_option> ::= <database_mirroring_option> ::= <date_correlation_optimization_option> ::= <db_encryption_option> ::= <db_state_option> ::= <db_update_option> ::= <db_user_access_option> ::= <external_access_option> ::= <FILESTREAM_options> ::= <HADR_options> ::= <parameterization_option> ::= <recovery_option> ::= <service_broker_option> ::= <snapshot_option> ::= <sql_option> ::= <termination> ::=
PostgreSQL
Dari Manual PostgreSQL 9.5:
ALTER DATABASE name [ [ WITH ] option [ ... ] ] where option can be: ALLOW_CONNECTIONS allowconn CONNECTION LIMIT connlimit IS_TEMPLATE istemplate ALTER DATABASE name RENAME TO new_name ALTER DATABASE name OWNER TO { new_owner | CURRENT_USER | SESSION_USER } ALTER DATABASE name SET TABLESPACE new_tablespace ALTER DATABASE name SET configuration_parameter { TO | = } { value | DEFAULT } ALTER DATABASE name SET configuration_parameter FROM CURRENT ALTER DATABASE name RESET configuration_parameter ALTER DATABASE name RESET ALL

Menggunakan GUI
Sebagian besar DBMS memungkinkan Anda mengubah database menggunakan GUI. Ini bisa berupa GUI yang disertakan dengan produk atau yang dikembangkan oleh pihak ketiga. Misalnya, MySQL Workbench adalah alat GUI yang dapat digunakan dengan MySQL.
