SQL 存储过程：如何连接参数值？

Question

这是原始代码：

EXEC @ReturnCode = msdb.dbo.sp_add_jobstep @job_id=@jobId, @step_name=N'TestStep', 
        @step_id=1, 
        @cmdexec_success_code=0, 
        @on_success_action=1, 
        @on_success_step_id=0, 
        @on_fail_action=2, 
        @on_fail_step_id=0, 
        @retry_attempts=0, 
        @retry_interval=0, 
        @os_run_priority=0, @subsystem=N'SSIS', 
        @command=N'/ISSERVER "\"\SSISDB\FolderName\ProjectName\PackageName.dtsx\"" /SERVER localhost /ENVREFERENCE 9 /Par "\"$ServerOption::LOGGING_LEVEL(Int16)\"";1 /Par "\"$ServerOption::SYNCHRONIZED(Boolean)\"";True /CALLERINFO SQLAGENT /REPORTING E', 
        @database_name=N'master', ...

我想做这样的事情（用动态值替换长字符串中 ENVREFERENCE 之后的值）：

DECLARE @myVariable int
SET @myVariable = 10

EXEC @ReturnCode = msdb.dbo.sp_add_jobstep @job_id=@jobId, @step_name=N'TestStep', 
        @step_id=1, 
        @cmdexec_success_code=0, 
        @on_success_action=1, 
        @on_success_step_id=0, 
        @on_fail_action=2, 
        @on_fail_step_id=0, 
        @retry_attempts=0, 
        @retry_interval=0, 
        @os_run_priority=0, @subsystem=N'SSIS', 
        @command=N'/ISSERVER "\"\SSISDB\AccuCenter\AccuCenterDBImport\VehicleMake.dtsx\"" /SERVER localhost /ENVREFERENCE ' + @myVariable + N' /Par "\"$ServerOption::LOGGING_LEVEL(Int16)\"";1 /Par "\"$ServerOption::SYNCHRONIZED(Boolean)\"";True /CALLERINFO SQLAGENT /REPORTING E', 
        @database_name=N'master'

你不能把整体放在一个变量中吗？

DECLARE @myCommand nvarchar(max)
SET @myCommand = N'/ISSERVER "\"\SSISDB\AccuCenter\AccuCenterDBImport\VehicleMake.dtsx\"" /SERVER localhost /ENVREFERENCE '
    + LTRIM(STR(@myVariable))
    + N' /Par "\"$ServerOption::LOGGING_LEVEL(Int16)\"";1 /Par "\"$ServerOption::SYNCHRONIZED(Boolean)\"";True /CALLERINFO SQLAGENT /REPORTING E'

顺便说一句，您可以完全根据自己的需要构建它。

然后在调用的时候使用sp_add_jobstep:

EXEC @ReturnCode = msdb.dbo.sp_add_jobstep
                @job_id=@jobId,
                @step_name=N'TestStep', 
                @step_id=1, 
                @cmdexec_success_code=0, 
                @on_success_action=1, 
                @on_success_step_id=0, 
                @on_fail_action=2, 
                @on_fail_step_id=0, 
                @retry_attempts=0, 
                @retry_interval=0, 
                @os_run_priority=0, @subsystem=N'SSIS', 
                @command=@myCommand
                @database_name=N'master'
