Postgresql函数执行错误

我创建了两个函数。我想在主函数中运行这些函数。当我运行main函数时，我得到一个错误。我怎样才能解决这个问题

注意：受影响的行为0 上下文：SQL语句“选择更新\u报废\u v15（）” PL/pgSQL函数所有函数（）SQL语句第15行 错误：查询没有结果数据的目标 提示：如果要放弃选择的结果，请改用“执行”。 上下文：PL/pgSQL所有函数（）SQL语句第15行

这是我的第一个函数

在postgres中，如果函数返回

void

则键入由

PERFORM

调用的类型

相反：

Select update_scrap_v15();

使用以下命令：

PERFORM update_scrap_v15();

提示：如果要放弃选择的结果，请使用PERFORM。

我知道。我怎样才能改变这个功能？真的吗？将SELECT替换为性能，如“执行更新\报废\ v15（）；获取诊断adm \ U 1=行\计数；发出通知'受影响=%”，adm \ U 1；执行报废\类型（）；获取诊断adm \ U 2=行\计数；发出通知'受影响=%”，adm \ U 2；”？感谢PostgreSQL的维护人员-该错误消息为您提供了问题的答案。
