首先构造树结构表：如表名为“kjkm”，字段分别为“科目代码”，“科目名称”，“上级科目代码”

&& 加载树

SQL code

if used("kjkm")==.f.    use kjkm shared in 0 alias kjkmendifselect * from kjkm order by 科目代码 into cursor curKjkmselect curKjkmgo topscan    nod=thisform.treeview1.nodes    if empty(alltrim(curKjkm.上级科目代码))==.t.        nod.add( , 1, alltrim(curKjkm.科目代码)+"_", alltrim(curKjkm.科目代码)+" "+alltrim(curKjkm.科目名称) )    else        nod.add( alltrim(curKjkm.上级科目代码)+"_", 4, alltrim(curKjkm.科目代码)+"_", alltrim(curKjkm.科目代码)+" "+alltrim(curKjkm.科目名称) )    endifendscanuse in curKjkm
