篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了5月29 流程相关的知识，希望对你有一定的参考价值。

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
);
