sql-server – 在SQL Server查询中关闭NOCOUNT有什么优点和缺点?

sql Server查询关闭NOCOUNT有什么优点和缺点?

解决方法

sql BOL:

SET NOCOUNT ON prevents the sending of
DONE_IN_PROC messages to the client
for each statement in a stored
procedure. For stored procedures that
contain several statements that do not
return much actual data,setting SET
NOCOUNT to ON can provide a
significant performance boost
,because
network traffic is greatly reduced.
