存储过程与函数不能同名
最近更新时间: 2024-06-12 15:06:00
如创建一个与函数同名的存储过程会提示function xxx already exists with same argument types。
postgres=# CREATE OR REPLACE FUNCTION proc_1() RETURNS void AS
$$
begin
raise notice 'Hello TBase';
end;
$$
LANGUAGE PLPGSQL;
CREATE FUNCTION
postgres=# CREATE PROCEDURE proc_1() AS
$$
begin
raise notice 'Hello TBase';
end;
$$
LANGUAGE PLPGSQL;
ERROR: function "proc_1" already exists with same argument types
postgres=#
#如果你要替换，则提示
postgres=# CREATE OR REPLACE PROCEDURE proc_1() AS
$$
begin
raise notice 'Hello TBase';
end;
$$
LANGUAGE PLPGSQL;
ERROR: cannot change routine kind
DETAIL: "proc_1" is a function.
