我试图在mysql(xampp)中实现一个过程。问题是我已经在sql server中编写了存储过程我不确定这是否适合迁移到phpmyadmin,但它应该转换为xampp,如果这非常简单,我很抱歉,但这是我第一次运行过程。
如果有人能告诉我该怎么做,我将不胜感激。
谢谢!这是我的sql server存储过程

为了将存储过程从mssql更改为mysql,您应该检查整个脚本,同时考虑到两种语言之间存在的sintax更改。
看看您的sp,以下是一些需要更改的内容,以使其在mysql中工作(可能还有更多):
创建sp时使用:
你必须使用
DELIMITER
以避免意外的语法错误。看到了吗https://dev.mysql.com/doc/refman/8.0/en/stored-programs-defining.html在mysql中,临时表的创建是不同的:
这个
UPDATE ... FROM ...
语法在mysql中无效,应尝试以下操作:设置变量:
一个变量:
多变量:
这个
WHILE
语法不同。检查https://dev.mysql.com/doc/refman/8.0/en/while.html即使是执行sp也是不同的:
