hi!
i use mysqldac to conect to a mysql database. i've connected my table to
a dbgrid. i want to walk through my table and copy some data to  a
string. how do i do this ?


  form1.mySQLTable1.FindFirst;
  while form1.mySQLTable1.FindNext do
  begin
     form1.mySQLTable1.FieldByName('eMail').AsString;
  end;


this doesn't work. Theres another function "GetCurrentRecord(Buffer:PCHar):Boolean".
How do I get the field datas into strings ?

OR Just

var
 MyString: String;
 MyInteger: Integer;

 mySQLTable1.First;
 while not mySQLTable1.Eof do
 begin
  MyString:=  FieldByName('Field1').asSTring;
  MyInteger:=  FieldByName('Field2').asInteger;
 mySQLTable1.Next;
 end;

as shaneholmes said,
if you need a subset of the tablecontent,
which you will iterate through,
apply a filter before
