---

EC（'CREATE PROCEDURE mySchema.myProc AS SET NOCOUNT ON；'）将PROCEDURE mySchema.myProc@DeclaredParmsGoHere数据类型更改为BEGIN@rasoo我不相信您可以在Sql Server中做到这一点，我想不出您想要这样做的原因。go命令分隔各个批处理命令。一旦删除一条语句，就会出现一个错误，即“alter”语句必须是批处理中的第一条语句。此外，Go使代码更易于阅读，因为它正确地表明，如果不存在该过程，则创建该过程的步骤是它自己的批处理，更改该过程的步骤也是如此。但我必须这么做。我正在为c#project中的project编写sql脚本。这将在部署期间执行。而且它不支持“go”。目前我已经做了一个变通办法，创建两个独立的sql脚本文件。第一个是检查和创建。下一个是alter过程。不过，这个过程改变了过程。如果有人已经创建了它的更新版本，而现在我们正在覆盖它，该怎么办？如果程序已经存在，如何避免修改，如果不存在，如何避免创建新的程序，以避免丢失现有的程序代码？我完全不理解你的评论。上面的语句使用alter，这意味着它将更改数据库中存在的任何编译版本。如果有人创建了较新版本的proc，您应该创建较新版本的较新版本。整个要点是修改过程。我否决了这一点，因为语句的语法不正确。至少，您应该尽一点努力并测试该语句。显然，该语法对于SQL Server的现代实例是正确的（v2016，2017，…）。要摆脱撇号似乎很麻烦。
