Sql 职能（程序）

我有许多不同的查询（这里是一个示例）

我想及时完成一项工作，为此我想将请求保存为过程，如何正确编写它们

DECLARE
  variable_name datatype;
BEGIN
  statements;
EXCEPTION
WHEN exception_name THEN
  statements;
END;

或

---

用我的值写一个例子。

创建或替换函数。。。返回自PostgreSQL 11以来的void

->

创建或替换过程。
语言“plpgsql”
->
语言sql
对于这组操作就足够了<代码>在空输入时调用

->没有输入<代码>安全调用程序-

安全定义程序

可能更灵活。

CREATE OR REPLACE FUNCTION dict.only_dict (
