关于SQL2000+VFP问题，以下代码请各大虾帮忙查一下问题出在哪里，不胜感激
任务：读取SQL2000中两个表tbljlcs和tbljlcs-1，其中tbljlcs为主表，tbljlcs-1为付表，索引关键字为jydh，希望运行后，从SQL2000获取的表能关联起来，以便进行查询、编辑等作业。
目前运行以下代码
1.表格内数据不能显示
2.SQL2000中两个表都有数据，但是查询后关联的记录为0
表单init：
nHandle=GetConnHandle()
IF nHandle>0
nResult=SQLEXEC(nHandle,"SELECT * FROM tbljlcs","curjlcs")
IF nResult<=0
=MESSAGEBOX("读取数据出错！",0+48,"提示")
This.opgFind.Enabled=.F.
This.cmdStart.Enabled=.F.
ENDIF
ENDIF
This.SetGrid() &&设置grdFind表格的属性
Thisform.Refresh
