Zeoslib Portal

Hi, I am looking for a way to see if there have been data changes to save wasting time over-writing a basically duplicate file for backup.

I tried using FileAge(FName) but it appears that Zeos 6.6 writes stuff to the file whether data was changed or not so that's no help.

I checked the SQLIte wiki and there is a "Changes()" function within SQLite which I think, will do exactly what I need.

Is that implemented in 6.6 (using D5, so can't go to 7) for an entire database file or just on a table-by-table basis?

Thanks

Hello

to find out if this has been implemented in some way you could have a look at the sqlite specific files in the plain and dbc directory. But honestly I doubt that. In that case your only option is to check wether you can implemet it yourself. I think that nobody will add new features to the 6.6-Branch currently.
With best regards,

Jan
