Hi all......
I have a some paradox tables with important data in them and i'd like to add some fields to them.
I have written a program that adds the fields with "TTable.CreateTable" but the problem is that the data disappears !!!
Is there a way to avoid this and add the fields without the data lost ???

Use SQL. This must be done exclusively, meaning the table cannot be active in your application or another application,  while SQL is executing.

Example: To add a new field, called 'TEST' to the ANIMALS table write:

      with Query1 do
      begin
        DatabaseName:='DBDEMOS';
        SQL.Text:='ALTER TABLE "ANIMALS.dbf" ADD TEST SMALLINT';
        ExecSQL;
      end;

for more information on SQL statements see:
