关于流程处理需要访问的数据库名有：Users,FlowPath,UserPath,LiuCheng
#流程表 create table LiuCheng ( Code varchar(50)primary key, #流程代号 Name varchar(50) #流程名称 ); #流程对应节点表 create table FlowPath ( Ids int auto_increment primary key, #节点代号 Code varchar(50) references LiuCheng(Code), # 流程代号 Uids varchar(50) references Users(UserName),#节点人员代号 Orders int #节点次序号 ); #用户发起流程表 create table UserFlow ( Ids int auto_increment primary key, #代号 Code varchar(50) references LiuCheng(Code), # 流程代号 Uid varchar(50) references Users(UserName),#发起人员代号 Content text,#流程内容 IsOk bit, #是否完成 RiQi datetime, # 发起日期 ToWhere int #流程到哪 );
