<P>在web页面上实现树状结构,有点麻烦.<BR>在最近的一个MIS<A
href="http://www.chinaitpower.com/System/index.html"
target=_blank>系统</A>的开发中,我们项目组大量用到了树结构:比如人员的选择,单位的选择等待.<BR>这个MIS<A
href="http://www.chinaitpower.com/System/index.html"
target=_blank>系统</A>所用的<A
href="http://www.chinaitpower.com/Dev/DataBase/index.html"
target=_blank>数据库</A>是oracle 9i.& oracle 9i 的<A
href="http://www.chinaitpower.com/Dev/DataBase/MsSql/index.html"
target=_blank>sql</A>支持迭代查询.我们的树是由牛人彭越写的,不过<BR>也参照了<A
href="http://www.chinaitpower.com/Net/index.html"
target=_blank>网络</A>上比较著名的xtree(可以到此下载:http://webfx.eae.net/),他的树算法支持无限级的树结构,不过性能好像<BR>很慢.我持保留态度.<BR>他用到的关键技术就是这句话:<BR>String
<A href="http://www.chinaitpower.com/Dev/DataBase/MsSql/index.html"
target=_blank>sql</A> = "select dwxh,dwbh,dwmc,dwfxh,level cc from xt_dw
connect by& prior dwxh = dwfxh start with dwfxh = 0";<BR>可是许多<A
href="http://www.chinaitpower.com/Dev/DataBase/index.html"
target=_blank>数据库</A>不支持迭代查询,并且迭代查询速度真是不能忍受.有什么更好的办法呢.下面说说我的解决方案.</P>
<P>一:需求的提出<BR>1:客户需要一个关于部门人员的树结构,<A
href="http://www.chinaitpower.com/Dev/DataBase/index.html"
target=_blank>数据库</A>为my<A
href="http://www.chinaitpower.com/Dev/DataBase/MsSql/index.html"
target=_blank>sql</A>4.1<BR>2:<A
href="http://www.chinaitpower.com/Dev/Programme/Java/index.html"
target=_blank>java</A>实现<BR>二:建表:<BR>1:<BR>用户信息表:<BR>各字段为:用户序号,用户编号,用户名称,单位序号,密码,用户登陆号<BR>create
table XT_YH<BR>(<BR>& YHXH& INT(9) NOT NULL auto_increment
PRIMARY KEY,<BR>& YHBH& VARCHAR(30),<BR>& YHMC&
VARCHAR(30),<BR>& DWXH& INT(9),<BR>& PWD&&
VARCHAR(20),<BR>& YHDLH VARCHAR(30)<BR>)<BR>--插入三条测试数据:<BR>--insert
into xt_yh(yhbh,yhmc,dwxh,pwd,yhdlh)
values('licl','李春雷',2,'password','licl')<BR>--insert into
xt_yh(yhbh,yhmc,dwxh,pwd,yhdlh)
values('fengx','冯欣',2,'password','fengx')<BR>--insert into
xt_yh(yhbh,yhmc,dwxh,pwd,yhdlh)
values('wangqx','王庆香',6,'password','wangqx')<BR>2:<BR>单位部门表<BR>各字段为:单位序号,单位编号,单位名称,单位父序号<BR>create
table XT_DW<BR>(<BR>& DWXH& int(9) NOT NULL auto_increment
PRIMARY KEY,<BR>& DWBH& VARCHAR(10),<BR>& DWMC&
VARCHAR(30),<BR>& DWFXH int(9)<BR>)<BR>--插入5条测试数据<BR>--insert into
xt_dw(dwbh,dwmc,dwfxh) values('0100000000','武汉科技局',0);<BR>--insert into
xt_dw(dwbh,dwmc,dwfxh) values('0101000000','人事处',1);<BR>--insert into
xt_dw(dwbh,dwmc,dwfxh) values('0102000000','后勤处',1);<BR>--insert into
xt_dw(dwbh,dwmc,dwfxh) values('0101010000','人事处son1',2);<BR>--insert into
xt_dw(dwbh,dwmc,dwfxh) values('0101020000','人事处son2',2);<BR>--insert into
xt_dw(dwbh,dwmc,dwfxh) values('0102010000','后勤处son1',3);</P>
<P>注意:<BR>为了实现快速的树结构实现,我需要充分利用单位编号DWBH,DWBH才有10位编码,其中,第一第二位表示一级单位,第三第四位表示二级单位,<BR>第五六位表示三级单位...那么10位编码就可以实现五级单位的树结构.<BR>比如:测试数据的树结构如下:<BR>&
1& 武汉科技局:<BR>&2& 人事处<BR>&&3&
人事处son1<BR>&&3& 人事处son2<BR>&2&
后勤处<BR>&&3后勤处son1</P>
<P>其实XT_DW表中的父序号是多余的.不过如果你要用迭代算法来实现,就是必须的<BR>才有10位编码,我只需要一句简单快速的<A
href="http://www.chinaitpower.com/Dev/DataBase/MsSql/index.html"
target=_blank>sql</A>语句就可以实现树结构:<BR>String <A
href="http://www.chinaitpower.com/Dev/DataBase/MsSql/index.html"
target=_blank>sql</A> = "select dwxh,dwbh,dwmc,dwfxh from xt_dw order by
dwbh"<BR>这句<A
href="http://www.chinaitpower.com/Dev/DataBase/MsSql/index.html"
target=_blank>sql</A>在几乎所有的<A
href="http://www.chinaitpower.com/Dev/DataBase/index.html"
target=_blank>数据库</A>平台都能执行,速度也快.<BR>下面贴出采用xtree,用10位编码而不是迭代算法实现的树:</P>

<P>在web页面上实现树状结构,有点麻烦.<BR>在最近的一个MIS<A
href="http://www.chinaitpower.com/System/index.html"
target=_blank>系统</A>的开发中,我们项目组大量用到了树结构:比如人员的选择,单位的选择等待.<BR>这个MIS<A
href="http://www.chinaitpower.com/System/index.html"
target=_blank>系统</A>所用的<A
href="http://www.chinaitpower.com/Dev/DataBase/index.html"
target=_blank>数据库</A>是oracle 9i.& oracle 9i 的<A
href="http://www.chinaitpower.com/Dev/DataBase/MsSql/index.html"
target=_blank>sql</A>支持迭代查询.我们的树是由牛人彭越写的,不过<BR>也参照了<A
href="http://www.chinaitpower.com/Net/index.html"
target=_blank>网络</A>上比较著名的xtree(可以到此下载:http://webfx.eae.net/),他的树算法支持无限级的树结构,不过性能好像<BR>很慢.我持保留态度.<BR>他用到的关键技术就是这句话:<BR>String
<A href="http://www.chinaitpower.com/Dev/DataBase/MsSql/index.html"
target=_blank>sql</A> = "select dwxh,dwbh,dwmc,dwfxh,level cc from xt_dw
connect by& prior dwxh = dwfxh start with dwfxh = 0";<BR>可是许多<A
href="http://www.chinaitpower.com/Dev/DataBase/index.html"
target=_blank>数据库</A>不支持迭代查询,并且迭代查询速度真是不能忍受.有什么更好的办法呢.下面说说我的解决方案.</P>
<P>一:需求的提出<BR>1:客户需要一个关于部门人员的树结构,<A
href="http://www.chinaitpower.com/Dev/DataBase/index.html"
target=_blank>数据库</A>为my<A
href="http://www.chinaitpower.com/Dev/DataBase/MsSql/index.html"
target=_blank>sql</A>4.1<BR>2:<A
href="http://www.chinaitpower.com/Dev/Programme/Java/index.html"
target=_blank>java</A>实现<BR>二:建表:<BR>1:<BR>用户信息表:<BR>各字段为:用户序号,用户编号,用户名称,单位序号,密码,用户登陆号<BR>create
table XT_YH<BR>(<BR>& YHXH& INT(9) NOT NULL auto_increment
PRIMARY KEY,<BR>& YHBH& VARCHAR(30),<BR>& YHMC&
VARCHAR(30),<BR>& DWXH& INT(9),<BR>& PWD&&
VARCHAR(20),<BR>& YHDLH VARCHAR(30)<BR>)<BR>--插入三条测试数据:<BR>--insert
into xt_yh(yhbh,yhmc,dwxh,pwd,yhdlh)
values('licl','李春雷',2,'password','licl')<BR>--insert into
xt_yh(yhbh,yhmc,dwxh,pwd,yhdlh)
values('fengx','冯欣',2,'password','fengx')<BR>--insert into
xt_yh(yhbh,yhmc,dwxh,pwd,yhdlh)
values('wangqx','王庆香',6,'password','wangqx')<BR>2:<BR>单位部门表<BR>各字段为:单位序号,单位编号,单位名称,单位父序号<BR>create
table XT_DW<BR>(<BR>& DWXH& int(9) NOT NULL auto_increment
PRIMARY KEY,<BR>& DWBH& VARCHAR(10),<BR>& DWMC&
VARCHAR(30),<BR>& DWFXH int(9)<BR>)<BR>--插入5条测试数据<BR>--insert into
xt_dw(dwbh,dwmc,dwfxh) values('0100000000','武汉科技局',0);<BR>--insert into
xt_dw(dwbh,dwmc,dwfxh) values('0101000000','人事处',1);<BR>--insert into
xt_dw(dwbh,dwmc,dwfxh) values('0102000000','后勤处',1);<BR>--insert into
xt_dw(dwbh,dwmc,dwfxh) values('0101010000','人事处son1',2);<BR>--insert into
xt_dw(dwbh,dwmc,dwfxh) values('0101020000','人事处son2',2);<BR>--insert into
xt_dw(dwbh,dwmc,dwfxh) values('0102010000','后勤处son1',3);</P>
<P>注意:<BR>为了实现快速的树结构实现,我需要充分利用单位编号DWBH,DWBH才有10位编码,其中,第一第二位表示一级单位,第三第四位表示二级单位,<BR>第五六位表示三级单位...那么10位编码就可以实现五级单位的树结构.<BR>比如:测试数据的树结构如下:<BR>&
1& 武汉科技局:<BR>&2& 人事处<BR>&&3&
人事处son1<BR>&&3& 人事处son2<BR>&2&
后勤处<BR>&&3后勤处son1</P>
<P>其实XT_DW表中的父序号是多余的.不过如果你要用迭代算法来实现,就是必须的<BR>才有10位编码,我只需要一句简单快速的<A
href="http://www.chinaitpower.com/Dev/DataBase/MsSql/index.html"
target=_blank>sql</A>语句就可以实现树结构:<BR>String <A
href="http://www.chinaitpower.com/Dev/DataBase/MsSql/index.html"
target=_blank>sql</A> = "select dwxh,dwbh,dwmc,dwfxh from xt_dw order by
dwbh"<BR>这句<A
href="http://www.chinaitpower.com/Dev/DataBase/MsSql/index.html"
target=_blank>sql</A>在几乎所有的<A
href="http://www.chinaitpower.com/Dev/DataBase/index.html"
target=_blank>数据库</A>平台都能执行,速度也快.<BR>下面贴出采用xtree,用10位编码而不是迭代算法实现的树:</P>
