oracle - ORA-00907: 循环游标的动态 sql 缺少右括号错误

问题描述

这段代码编译得很好，但是当我运行它时出现以下错误：

ERROR at line 1:
ORA-00907: missing right parenthesis
ORA-06512: at "BOB.JUST_ME", line 69
ORA-06512: at line 1

可能是这条线？

open cur for v_sql1 using TOTAL_ROW_COUNT,C_TOTAL_ROW_COUNT;

在我声明的动态 SQL 中，我试图选择这些值，但在循环运行之前它们不会被填充。不知道这是否是正确的做法......

create or replace procedure JUST_ME is

我认为代码可能有其他问题，所以如果有人看到更好的方法，请大声疾呼！谢谢你。

解决方案

这里：

(:C_TOTAL_ROW_COUNT,7)

具体来说,7是错误的原因。
