DELETE AgentResultLinks.*

有人可以帮助我在紧凑型数据库的vaid mssql查询中转换此查询吗？表演非常重要.

我有这个sql:

UPDATE JOBMAKE SET WIP_STATUS='10sched1'
WHERE JBT_TYPE IN (SELECT JBT_TYPE FROM JOBVISIT WHERE JVST_ID = 21)
AND JOB_NUMBER IN (SELECT JOB_NUMBER FROM JOBVISIT WHERE JVST_ID = 21)

它一直有效,直到我把它变成参数化查询:

UPDATE JOBMAKE SET WIP_STATUS='10sched1'
WHERE JBT_TYPE IN (SELECT JBT_TYPE FROM JOBVISIT WHERE JVST_ID = @jvst_id)
AND JOB_NUMBER IN (SELECT JOB_NUMBER FROM JOBVISIT WHERE JVST_ID = @jvst_id)

Duplicated parameter names are not allowed. [  Parameter name = @jvst_id ]

我试过这个(我认为它可以在SQL SERVER 2005中使用 - 虽然我没有尝试过):

UPDATE JOBMAKE 
SET WIP_STATUS='10sched1' 
FROM JOBMAKE JM,JOBVISIT JV
