MSSQLでいくつかのストアドプロシージャを実行します。MS SQL Server Management Studioでプロシージャを実行すると、常に列ヘッダーが返されます。Delphiプログラムでもこの機能を利用しようとしています。現在、データセットに行がない場合、ヘッダーは返されません。Delphi 7、TADOStoredProc、TADODataset、および文字列グリッドを使用します。
ADOStoredProc1.ObjectView := True;
ADOStoredProc1.Open;
ADODataSet1.Recordset := ADOStoredProc1.Recordset;
// process the first dataset, which contains rows
if not ADODataSet1.IsEmpty then
begin
AdvGridWorkbook1.ActiveSheet := 0;
// build grid header
SetupHeader;
// build grid detail
SetupDetail;
end
else
begin
Memo1.Lines.Add('Returned empty data set for Mapping');
end;
// load the next dataset. no data rows but MS Studio shows column headers
ADODataSet1.Recordset := ADOStoredProc1.NextRecordset(RecordsAffected);
if not ADODataSet1.IsEmpty then // tests as empty
begin
AdvGridWorkbook1.ActiveSheet := 1;
// build grid header - none are returned as IsEmpty = True
SetupHeader;
// build grid detail
SetupDetail;
end
else
begin
// this message is added to my memo field.
Memo1.Lines.Add('Returned empty data set for Labor');
end;
ADODataSet1.Close;
ADOStoredProc1.Close;
MSが列ヘッダーを取得する方法を知っている人はいますか?
ストアドプロシージャは次のとおりです。
