What am I doing wrong...

Hello...
I am using just the usual TTable and TQuery (for SQL statments) components
and every once in a while I lost some data in my tables... I mean the data -
usually the previous day's ones - phisically disappear in my .db file... Why
is that?
I am using Paradox7 databases and I have set the primary and secondary
(for alphabetical sorting) indexes...

My example of inserting data into the table:
---------------------------------
TTable1.Append;
TTable1NameAndSurname.AsString:="Frank Sinatra";
...
TTable1.Post;
---------------------------------

I think that is all... Why does it loose some data almost every mont?
I heard something about recovering the indexes or something...
What is that and if it helps, how can I do that?

Thanks for all,
-Andrej

Have you set Local Share to true in the BDE configuration? This is one
of the primary causes of this.

HTH,

Re:What am I doing wrong...

Well, that didn't make much sense ;-)
I should have said that Local Share should be true. If it is false,
the BDE caches your changes until who knows when... Closing the app
will send it all to the hard disc. But, if something happens in the
mean time, all is lost.

Re:What am I doing wrong...

Seems to me that paradox doesn't flush buffer to disk.
Try setting LOCAL SHARE to TRUE in paradox settings in BDE admin.
Also, I find
table.insert
..
table.post

far more reliable then append command.
