问题 I have downloaded SQL SERVER MANAGEMENT STUDIO but SQL SERVER AGENT is not found. Should I install it separately? Can anybody tell me the link where SQL SERVER AGENT is available as a Freeware to download it? 回答1: The agent is not visible if you use SQL Server Management Studio Express to connect to an SQL Server.

问题 I have a stored procedure that has a optional parameter, @UserID VARCHAR(50) .
