使用C#把dbf格式檔案的資料導入到sqlserver中

SQL語句如下:

string sql = @"delete yzxt "+

      "insert into yzxt ( service_id,name,apply_st,stop_date,home_ph,address,bp,customer_l,id,"+

      "district_i,serving_st,source_id,service_fa,preserve15,innet_meth,service_gr,fee_kind,sumfee) "+

      "select service_id,name,apply_st,stop_date,home_ph,address,bp,customer_l,id,district_i,"+

      "serving_st,source_id,service_fa,preserve15,innet_meth,service_gr,fee_kind,sumfee from openrowset('"+

      "MSDASQL','Driver=Microsoft Visual FoxPro Driver; SourceDB="+this.filepath+"; SourceType=DBF', 'select * from "+this.filepath+"') where serving_st in (select id from dic_status) and serving_st <> '9'" ;
