系统字段条件判断要中@嘛

出现如下错误：工作流中条件节点的条件设置格式错误,请重新设置!select wf.id from workflow_file wf where wf.id=12 and (提交人职位级别 >= 6)

条件是写：提交人职位级别 ge 6，错误如下

或 @提交人职位级别@ ge 6，错误如下

业务错误 工作流中条件节点的条件设置格式错误,请重新设置!select wf.id from workflow_file wf where wf.id=13 and ((select c_pt.name from workflow_fileinbox c_box, system_users c_users, system_positionmember c_pm,system_position c_p,system_positiontype c_pt where c_box.id = 27 and c_box.user_id = c_users.id and c_users.id = c_pm.user_id and c_pm.isPrimary = 1 and c_p.deletedstatus=0 and c_pm.position_id=c_p.id and c_p.positiontype_id = c_pt.id) >= 6)

都会出错
