一、获取数据:
1.方式一
with cdsStaff do
begin
  Close;
  Params.Clear;
  with Params.CreateParam(ftString, 'i_numcode', ptInput) do
    AsString := trim(edtNumcode.Text);

  with Params.CreateParam(ftString, 'i_psw', ptInput) do
    AsString := dmpub.PswEcyt(trim(edtPasswd.Text));

  strSql := 'SELECT * FROM STAFF WHERE NUMCODE = :i_numcode AND PSW = :i_psw and nvl(IsWas,0) = 0';//lye 120106增加非废码条件
  Data := dmPub.GetData(strSql, Params);
  Open;
end;
2.方式二
with cdsTmp do
begin
  CommandText :=
    ' select p.*                   ' +
    ' from MatPriceAdjPN p         ' +
    ' where p.State=:State         ' +
    ' order by billid              ';
  Params.ParamByName('State').AsInteger := C_BILL_CONFIRMED;
  Params.ParamByName('BillDate').AsDateTime := dmPub.GetRemoteTime;
  Params.ParamByName('DepID').AsInteger := CurStf.DepID;
  data := dmPub.GetData(CommandText, Params, false);
end;

二、执行SQL语句:
1.方式一:
cdsTmp : TwwClientDataSet;
cdsTmp := TwwClientDataSet.Create(self);
with cdsTmp do
begin
  Commandtext :=
    ' UPDATE MATAPLP          ' +
    ' SET OPID = :OPID        ' +
    ' WHERE BILLID = :BILLID  ';
  Params.ParamByName('OPID').AsInteger := fBillID;
  Params.ParamByName('BILLID').AsInteger := cdsBillBillID.Value;
  dmpub.ExecSQL(Commandtext,Params,o_result);
end;
 2.方式二:
with cdsSysParam do
begin
  strSQL := 'UPDATE SYSPARAM SET VALUE = :i_Value WHERE UPPER(PRMCODE) = :i_Prmcode';

  Close;
  Params.Clear;
  with Params.CreateParam(ftString, ':i_Value', ptInput) do
    AsString := InttoStr(WrValue);
  with Params.CreateParam(ftString, ':i_Prmcode', ptInput) do
    AsString := UpperCase(PrmCode);

  if ExecSQL(strSQL, Params, oResult) then
    Result := True
  else
    UtilsPub.MsgDlg('写系统参数表错误!' + oResult, mtInformation);
end;


三、运行储存过程:
1.方式一:
with dmPub.cdsStpPub do
begin
  Params.Clear;
  //设置参数
  with Params.CreateParam(ftInteger, 'i_actstf', ptInputOutput) do
    AsInteger := Actcon.ActStf;
  with Params.CreateParam(ftString, 'i_actcode', ptInputOutput) do
    AsString := Actcon.ActCode;
  with Params.CreateParam(ftInteger, 'i_bedid', ptInputOutput) do
    AsInteger := Actcon.ActBedID;
  with Params.CreateParam(ftInteger, 'i_PatId', ptInputOutput) do
    AsInteger := Actcon.ActPatID;
  with Params.CreateParam(ftInteger, 'i_clinid', ptInputOutput) do
    AsInteger := Actcon.ActClinID;
  with Params.CreateParam(ftString, 'i_dspt', ptInputOutput) do
    AsString := Actcon.ActDec;

  //调用函数语句
  if not dmPub.RunProcedure('GenActLog', Params, oResult) then
  begin
    UtilsPub.MsgDlg(VartoStr(oResult),mtInformation);
    Result := False;
  end
  else
    Result := True;
end;
2.方式二:

Params := TParams.Create(nil);
try
  Params.CreateParam(ftInteger, 'i_BillIDA', ptInput).AsInteger := cdsParentBill.FieldByName('BillID').AsInteger;
  Params.CreateParam(ftInteger, 'i_BillIDB', ptInput).AsInteger := cdsTmp.FieldByName('BillId').AsInteger;
  Params.CreateParam(ftString, 'o_Result', ptOutput);
  if not dmPub.RunProcedure('dsTwoMtBillIsEqu', Params, o_Result) then
  begin
    UtilsPub.MsgDlg(vartostr(o_Result), mtInformation, [MBOK]);
    Abort;
  end;
finally
  Params.Free;
end;
3.方式三:
var
  vResult:String;
  oResult: OleVariant;
  Param: TParams;
begin
  inherited;
  Param := TParams.Create(nil);
  Param.CreateParam(ftInteger, 'i_StfId', ptInput);
  Param.CreateParam(ftInteger, 'i_ID', ptInput);
  Param.CreateParam(ftInteger, 'i_BNo', ptInput);
  Param.CreateParam(ftString, 'o_Result', ptOutput);
  Param.ParamByName('i_StfId').AsInteger := CurStf.StfID;
  Param.ParamByName('i_ID').AsInteger := FID;
  Param.ParamByName('i_BNo').AsString := edtBNOS.Text;
  if not dmPub.RunProcedure('brPrintBNo', Param, oResult) then
  begin
    edtBNOS.SetFocus;
    edtBNOS.SelectAll;
    UtilsPub.MsgDlg(VartoStr(oResult), mtError,[mbOk]);
  end;
  Param.Free;
  ModalResult := mrOk;
end;

四、更新数据
1.方式一
sResult: string;
if not dmpub.UpdateData(cdsTmp, sResult) then
        utilspub.MsgDlg(sResult, mtError);
