oracle与sqlserver插入数据动态字段值

记录一下以备下次快速找到。。。
       往tb_wf_privgrant表中插入一条记录,workflow_id字段值从tb_wf_workflow 表中获取workflow_name='知识审核'的所有记录中workflow_id最大值。
--oracle
declare   a NUMBER(10);
   begin
   select  max(workflow_id) into a from tb_wf_workflow where workflow_name='知识审核';
   insert into tb_wf_privgrant(grant_Id,workflow_id,member_id,member_type,knowledge_code) values (HIBERNATE_SEQUENCE.NEXTVAL, a,'r001','R','6001');
   end;
--sqlserver
--方法一
insert into tb_wf_privgrant(workflow_id,member_id,member_type,knowledge_code)
   select max(workflow_id),'r001','R','6001' from tb_wf_workflow where workflow_name='知识审核'
--方法二
 declare   @a numeric(10,0)
   select   @a = max(workflow_id) from tb_wf_workflow where workflow_name='知识审核'
   insert into tb_wf_privgrant(workflow_id,member_id,member_type,knowledge_code)
   values (@a,'r001','R','6001')
