Title: ADO Dataset - CSV file
Question: how to export a ADO Dataset to a Comma Separated Values file
with a few lines of code.
Answer:
procedure TMainForm.SaveDataSetCSV;
const
adClipString = 2;
ColumnDelimiter = ';';
RowDelimiter = #13#10;
var
s : String;
fs : TFileStream;
begin
SaveDialog1.DefaultExt := '.CSV';
// build the default filename
SaveDialog1.FileName := ADOTable1.TableName+SaveDialog1.DefaultExt;
if SaveDialog1.Execute then
begin
// Get the complete dataset as CSV
// the underlying Recordset-Object does the whole work for you
s := ADOTable1.Recordset.GetString(adClipString, ADOTable1.Recordset.RecordCount, ColumnDelimiter, RowDelimiter, '');
// save the CSV string to a file
fs := TFileStream.Create(SaveDialog1.FileName, fmCreate);
try
fs.WriteBuffer(s[1], Length(s));
finally
fs.Free;
end;
end;
end;
