CREATE OR REPLACE PROCEDURE "SP_MM_QC_DATA_MACH_JUN"

        order by 1,2,3;
END;

我有错误

错误：PL/SQL：
ORA-00904: "S"."ID_MM_SEC": 标识符无效
行：19 文本：AND S.ID_MM_SEC = PSEC 错误：
PL/SQL：忽略 SQL 语句
Line: 13 Text: select S.DESCRIPTION as SECTION, MT.CODE as MACHINE_TYPE, MH.MACH_NO

请指教。

PL/SQL：忽略 SQL 语句

此错误消息是 PL/SQL 编译器说的，我在 SQL 中发现了一个错误，我将不再检查。因此，关键信息是识别错误的信息。在你的情况下是这样的：

ORA-00904: "S"."ID_MM_SEC": 标识符无效

这是编译器告诉您表 MM_SPINSECTION 没有名为 ID_MM_SEC 的列。您需要检查表定义并获取实际的列名。
