UPDATE set条件如何进行判断
UPDATE WF_WORKFLOW_NODE_ELE Set user_code =initiator

from wf_workflow where WF_WORKFLOW_NODE_ELE.workflow_code=wf_workflow.workflow_code

而这个set user_code 如何进行判断？


因为在WF_WORKFLOW_NODE_ELE 中user_code 代表为一个人，前面有其他字段进行判断。


在线等，拜托了~~

--不是太理解lz的意思，看下面的2个语句是否有用？
UPDATE WF_WORKFLOW_NODE_ELE Set user_code =initiator 

from wf_workflow where WF_WORKFLOW_NODE_ELE.workflow_code=wf_workflow.workflow_code
and user_code ='判断条件'

UPDATE WF_WORKFLOW_NODE_ELE Set user_code =(case initiator  when .. then .. else ..end)

from wf_workflow where WF_WORKFLOW_NODE_ELE.workflow_code=wf_workflow.workflow_code

对user_code的判断条件就写在where后面

UPDATE WF_WORKFLOW_NODE_ELE Set user_code=new数据（新某人） 
from wf_workflow where user_code=条件（某人）
and WF_WORKFLOW_NODE_ELE.workflow_code=wf_workflow.workflow_code

没明白你的意思，不过你可以加个判断 case when 呗

UPDATE WF_WORKFLOW_NODE_ELE 
Set user_code = case when col='num1' then initiator else 'num2'  
from wf_workflow where WF_WORKFLOW_NODE_ELE.workflow_code=wf_workflow.workflow_code

[解决办法]
UPDATE WF_WORKFLOW_NODE_ELE Set user_code =initiator
from wf_workflow where WF_WORKFLOW_NODE_ELE.workflow_code=wf_workflow.workflow_code
and workflow_node_code='0000000002'
and workflow_nodeele_code='0000000002'

后面的


and workflow_node_code='0000000002'
and workflow_nodeele_code='0000000002'
竟然是user_code的判断？？？？

因为在WF_WORKFLOW_NODE_ELE 中u……

不是你说的么，user_code如何进行判断？？？

为什么不用存储过程,需要这么麻烦吗?
