ALTER ROUTINE

ALTER ROUTINE — 更改例程的定义

概要

ALTER ROUTINE name [ ( [ [ argmode ] [ argname ] argtype [, ...] ] ) ]
    action [ ... ] [ RESTRICT ]
ALTER ROUTINE name [ ( [ [ argmode ] [ argname ] argtype [, ...] ] ) ]
    RENAME TO new_name
ALTER ROUTINE name [ ( [ [ argmode ] [ argname ] argtype [, ...] ] ) ]
    OWNER TO { new_owner | CURRENT_ROLE | CURRENT_USER | SESSION_USER }
ALTER ROUTINE name [ ( [ [ argmode ] [ argname ] argtype [, ...] ] ) ]
    SET SCHEMA new_schema
ALTER ROUTINE name [ ( [ [ argmode ] [ argname ] argtype [, ...] ] ) ]
    [ NO ] DEPENDS ON EXTENSION extension_name

where action is one of:

    IMMUTABLE | STABLE | VOLATILE
    [ NOT ] LEAKPROOF
    [ EXTERNAL ] SECURITY INVOKER | [ EXTERNAL ] SECURITY DEFINER
    PARALLEL { UNSAFE | RESTRICTED | SAFE }
    COST execution_cost
    ROWS result_rows
    SET configuration_parameter { TO | = } { value | DEFAULT }
    SET configuration_parameter FROM CURRENT
    RESET configuration_parameter
    RESET ALL

说明

ALTER ROUTINE更改例程的定义，例程可以是聚合函数、普通函数或过程。有关参数、更多示例和进一步详细信息的说明，请参见ALTER AGGREGATE、ALTER FUNCTION和ALTER PROCEDURE。

示例

将类型为integer的例程foo重命名为foobar

ALTER ROUTINE foo(integer) RENAME TO foobar;

无论foo是聚合、函数还是过程，此命令均可运行。

兼容性

此语句与 SQL 标准中的ALTER ROUTINE语句部分兼容。有关更多详细信息，请参见ALTER FUNCTION和ALTER PROCEDURE。允许例程名称引用聚合函数是PostgreSQL扩展。

另请参阅

ALTER AGGREGATE、ALTER FUNCTION、ALTER PROCEDURE、DROP ROUTINE

注意，没有 CREATE ROUTINE 命令。
