Hi Helen... thanx a lot for your answer...
> why not move these old rows to a history table inside the database?Well... the reason is for time of transfer....
We have an application based in AstaTech using Delphi, so, the 2 DB's
propose don't work for us... and each time that our clients have a
problem with the application we need that they send to us them
DataBase to can solve the problem...
So, if the DB is big, the time of transfer has become very long...and
we can't connect directly to their DB because they have an Intranet
and we dont have access, so the only way to can assist them is
sending the DB by e-mail... They makes a GBK and send it to us, but
even GBK size is very large cause the historic table...
Thanx in advance
