在 pl/sql 过程中声明变量时出现语法错误

问题描述

这让我有点生气.我正在尝试向过程中添加一个变量，但它不起作用 - 我刚刚收到此错误消息:

This is sending me a bit mad. I'm trying to add in a variable to a procedure, but it wasn't working - I just got this error message:

[Error] 语法检查 (25: 7): ERROR line 25, col 7,ending_line 25,Ending_col 12，找到数字"，期待:；- 或 - .. := 默认NOT NULL -or- % -or- ( . @

[Error] Syntax check (25: 7): ERROR line 25, col 7, ending_line 25, ending_col 12, Found 'number', Expecting: ; -or- .. := DEFAULT NOT NULL -or- % -or- ( . @

我在下面编写了一个非常基本的程序来隔离问题，现在我完全卡住了，因为我看过的每个基本语法指南都说要做我所做的.为什么我不能声明如下所示的变量?如果这对我的问题有任何线索，我通常会在 SQL Server 中进行编码.如果有人能帮忙，非常感谢！

I knocked up a really basic procedure below to isolate the problem and now I'm completely stuck, as every basic syntax guide I've looked as says to do what I've done. Why can't i declare variables as shown below? I normally code in SQL Server if that's any clue as to my problem. Many thanks if anyone can help!

CREATE OR REPLACE PROCEDURE MRCS.pro_xxx_test1 (cats out sys_refcursor)
IS

declare

spoon number;

balls varchar2(3);

BEGIN

 open cats for select * from dual;

   end;

推荐答案

删除DECLARE".在函数/过程声明中不需要

Remove the "DECLARE". Not needed in a function / procedure declaration
