创建一个将返回表的SQL函数

Question

我试图创建一个返回表的Sql函数，但是当我尝试编译脚本时会抛出异常。我试图修复它超过一个小时。

错误例外：

ERROR:  syntax error at or near "$1"
LINE 1: ...name, oj.job_summary, oj.last_modified, d.num AS  $1 , oj.de...
                                                             ^

SQL函数查询：

Answer 1

看起来编译器与department_number混淆。

它使用了两次：作为输出参数out department_number INTEGER和查询列d.num AS department_number的别名。

尝试将department_number更改为其中一个地方的其他地方，它应该有效。

BTW：您使用的是什么版本的PostgreSQL？
