I want to import data from Excel into a Paradox database on Delphi 7.
How can I do that using Delphi?
Well, if you have the question tagged as Delphi 7 I assume you have BDE. This will enable you to do the whole process in Delphi.
You can modify and use this untested code (you will need to add the exception handling):
procedure TForm1.Button2Click(Sender: TObject);
var
Cols: integer;
Rows: integer;
IntCellValue: integer;
Excel, XLSheet: Variant;
failure: Integer;
begin
failure:=0;
try
Excel:=CreateOleObject('Excel.Application');
except
failure:=1;
end;
if failure = 0 then
begin
Excel.Visible:=False;
Excel.WorkBooks.Open(<Excell_Filename>);
XLSheet := Excel.Worksheets[1];
Cols := XLSheet.UsedRange.Columns.Count;
Rows := XLSheet.UsedRange.Rows.Count;
// Value of the 1st Cell
IntCellValue:=Excel.Cells[1, 1].Value;
// Iterate Cals/Rows to read the data section in your worksheet
// and you can write it in Paradox using the BDE by iterating all cells
// somthing like this pseudo code:
try
Query := TQuery.Create(nil)
Query .Databasename := PdxDBName; // must be configured in the BDE
while Rows > 0
begin
while Cols > 0
begin
IntCellValue:=Excel.Cells[Cols,Rows].Value;
Query .SQL.text := // SQLStmt including the IntCellValue
ExecSQL;
dec(Cols);
end;
Cols := XLSheet.UsedRange.Columns.Count;
Dec(Rows);
end;
finally
Query.Free;
end;
Excel.Workbooks.Close;
Excel.Quit;
Excel:=Unassigned;
end;
end;
