根据父机构查询子机构：

select t.id,rpad('　',level*3-2,'　')||'├'||t.jigouming AS OrgName from t_xt_jigouxinxi t
        start with trim(t.fujigou)IS Null /*父机构条件*/
        connect by prior t.id=t.fujigou;

根据子机构查询父机构：

 select t.id,rpad('　',level*3-2,'　')||'├'||t.jigouming AS OrgName from t_xt_jigouxinxi t
        start with trim(t.fujigou) IS NULL
        connect by prior t.fujigou='19a1b282c84e4d0b93e45de8e217cfc2';  /*需要查询的子机构的父机构ID*/


顺便记一下Sql Server的查询写法：

select (case   id   when   null   then   ''   else   space(id)   end   )   +OrgName   as   OrgName   from   Organization
