sqlserver 中使用print输出时如何能够立即看到

No. They will only be returned when a transaction is committed, when other record sets are returned or a statement is completed (go statement terminator in a SQL batch). You can use raiserror at non-fatal error levels (0-18) to get immediate feedback of this sort. For example:

RAISERROR ('Foo', 10, 1) WITH NOWAIT

使用raiserror函数进行输出，注意指定的错误为非致命性错误（raiserror中的第二个参数表示错误等级）（non-fatal error levels (0-18) ）

Use the RAISERROR function: RAISERROR( 'This message will show up right away...',0,1) WITH NOWAIT You shouldn't completely replace all your prints with raiserror. If you have a loop or large cursor somewhere just do it once or twice per iteration or even just every several iterations. Also: I first learned about RAISERROR at this link, which I now consider the definitive source on SQL Server Error handling and definitely worth a read: http://www.sommarskog.se/error-handling-I.html
