问题描述
如何通过 ADO.NET 在单个命令(单次执行)中执行以下 SQL?
How can I execute the following SQL inside a single command (single execution) through ADO.NET?
ALTER TABLE [MyTable]
ADD NewCol INT
GO
UPDATE [MyTable]
SET [NewCol] = 1
不支持批处理分隔符 GO
,如果没有它,第二个语句将失败.
The batch separator GO
is not supported, and without it the second statement fails.
除了使用多个 command
执行之外,还有其他解决方案吗?
Are there any solutions to this other than using multiple command
executions?
推荐答案
GO
关键字不是 T-SQL,而是一个 SQL Server Management Studio 神器,它允许您分离脚本的执行文件分多批.即当您在 SSMS 中运行 T-SQL 脚本文件时,语句会分批运行,由 GO
关键字分隔.可以在此处找到更多详细信息:https://msdn.microsoft.com/en-我们/图书馆/ms188037.aspx
The GO
keyword is not T-SQL, but a SQL Server Management Studio artifact that allows you to separate the execution of a script file in multiple batches.I.e. when you run a T-SQL script file in SSMS, the statements are run in batches separated by the GO
keyword. More details can be found here: https://msdn.microsoft.com/en-us/library/ms188037.aspx
如果你读到这里,你会发现 sqlcmd 和 osql 也支持 GO
.
If you read that, you'll see that sqlcmd and osql do also support GO
.
SQL Server 不理解 GO
关键字.因此,如果您需要等价物,则需要自行分离并单独运行批次.
SQL Server doesn't understand the GO
keyword. So if you need an equivalent, you need to separate and run the batches individually on your own.
