ALTER ROUTINE —更改例程的定义

Synopsis

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_USER | SESSION_USER }
ALTER ROUTINE name [ ( [ [ argmode ] [ argname ] argtype [, ...] ] ) ]
    SET SCHEMA new_schema
ALTER ROUTINE name [ ( [ [ argmode ] [ argname ] argtype [, ...] ] ) ]
    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

Description

ALTER ROUTINE更改例程的定义，该例程可以是聚合函数，普通函数或过程。有关参数的说明，更多示例和更多详细信息，请参见ALTER AGGREGATE，ALTER FUNCTION和ALTER PROCEDURE下的内容。

Examples

要将类型integer的例程foo重命名为foobar：

ALTER ROUTINE foo(integer) RENAME TO foobar;

此命令将独立于foo是聚合，函数还是过程而工作。

Compatibility

该语句与 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。
