--1:存儲過程返回dataset 的例子:

c# 代碼 :通用類

  public static int singlestcd(datetime starttime,datetime endtime,int smtp,string jl,string stdcd,string stcdstr, out dataset ds )
  {
   int ret=0;
   ds=null;
  
    oledbconnection constring=new oledbconnection(appraise.constr);
    oledbcommand cmd=new oledbcommand("p_get_stcd_singleappraise_xunqi",constring);
    try
    {
    oledbdataadapter ada=new oledbdataadapter();
     cmd.commandtype=commandtype.storedprocedure;
     cmd.parameters.add("@starttime", oledbtype.dbtimestamp).value=starttime ;
     cmd.parameters.add("@endtime", oledbtype.dbtimestamp).value=endtime ;
     cmd.parameters.add("@smtp", oledbtype.integer).value=smtp ;
     cmd.parameters.add("@jl", oledbtype.varchar, 50).value=jl ;
     //cmd.parameters.add("@stdcd", oledbtype.varchar, 50).value=stdcd ;  //評價標準
     cmd.parameters.add("@stcdstr", oledbtype.varchar, 8000).value=stcdstr ;

     system.data.dataset data = new dataset();
     ada.selectcommand = cmd;
     ada.fill(data,"table");
     ds = data;
     ret=ds.tables[0].rows.count;
     if ( ret ==-1 )
     {
      return -1000; //無數(shù)據(jù)
     }
     else
     {
      return ret;
     }

    }
    catch(exception e)
    {
     //數(shù)據(jù)庫操作發(fā)生錯誤,返回錯誤代碼
     system.diagnostics.debug.writeline(e.message);
     return -1001;
    }
    finally
    {
     constring.close();
     cmd.parameters.clear();
    }

vb.net 調(diào)用:

  private sub bindingdatagrid_query()
        dim ds as system.data.dataset
        zehua.water.appraise.singlestcd("1999-5-1", "1999-9-1", 1, "ⅲ", "", "50181300,50185050,50181350,50185100,50185150,50185200,50185250,50181200,50185150,51282300", ds)
        datagrid_query.datasource = ds
        datagrid_query.databind()
    end sub
