我能够复制错误;它准确地表明了问题。问题是您引用了令牌VARCHAR，导致proc认为您正在传递一个字符串，隐式转换为VARCHAR。由于UNIQUEIDENTIFIER未隐式转换为定义的use msdb
go
if OBJECT_ID('testString','P') is null
execute sp_executesql N'CREATE PROC testString as select ''stub'' stubProc'
go
alter proc testString
@job_id uniqueidentifier
as
declare @job_id_str varchar(200)
SET @job_id_str = UPPER( master.dbo.fn_varbintohexstr( @job_id ) )
select @job_id jobID, @job_id_str jobIDStr
，因此您会收到错误。
如果您只是删除引号<作业步骤中的 ，则一切都按设计工作。希望您不要尝试在SQL代理作业之外进行测试，否则无论您做什么都会失败。
