action

版本定义 PG 18

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
其中 action 是以下之一：

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

描述

ALTER ROUTINE更改一个例程的定义。术语“例程”包括聚合函数、普通函数和过程。参数说明、更多示例以及进一步细节，请分别参见ALTER AGGREGATE、ALTER FUNCTION和ALTER PROCEDURE。

示例

将针对integer类型的例程foo重命名为foobar：

ALTER ROUTINE foo(integer) RENAME TO foobar;

不管foo是聚合、函数还是过程，这条命令都可以工作。

兼容性

该语句与 SQL 标准中的ALTER ROUTINE语句部分兼容。更多细节请参见ALTER FUNCTION和ALTER PROCEDURE。允许例程名引用聚合函数是PostgreSQL的扩展。

另见

ALTER AGGREGATE, ALTER FUNCTION, ALTER PROCEDURE, DROP ROUTINE

注意，没有CREATE ROUTINE命令。
