出错代码：Webservice.cs:

[WebMethod]

public string MReportYW10_DetailList(string PurchaseID)

{

DataTable table = new DataTable();

try

{

string sql = @"select t.*,to_char(AMOUNT,'FM999,999,999,990.00') M_AMOUNT

from BU_MReport_YW10PurchaseID t where PurchaseID={0} order by Type,id";

sql = string.Format(sql, PurchaseID);

table = OracleHelper.ExecuteDataTable(sql);

}

catch { }

return Fun.GetJson(table);

}
