Question

我使用以下代码成功编译但是，当我测试时出现错误：

"ORA-00904" "VTX_HR" invalid identifier.

我不太确定我可以这样做，因为我是PLSQL的初学者：

Answer 1

问题在于你的execute immediate语句，你应该用这种方式替换它（将值不是变量名传递给字符串，应该执行）。（即使我没有得到逻辑，为什么你从现有的表中选择那些变量而从那个表中没有任何东西）。

Execute Immediate 'create table moe as select'||  v_emplid||','''||V_NAME||''','||V_ERNCD||','||V_MONDOL||','||
  V_MONHR||','||V_GRSDOL||','||V_GRSHR||','||VFX_DOL||','||VFX_HR||','||VSX_DOL||','||VSX_HR||','||VTX_DOL||','||VTX_HR||' FROM EARNBAL ';

我没有查看所有数据类型，但不要忘记将varchars放在这样的引号中

  ||','''||V_NAME||''',

执行立即语句以使用游标中的变量创建视图
