Updating Interbase data in VC++

Updating Interbase data in VC++

Does anybody have experience?? I tried it via the ATL-Templates but ist didn't work. I know it's possible via SQL statements but in my case it would be a great overhead...


RE: Updating Interbase data in VC++

I think you can try to do it through ADO using OLE DB provider for ODBS. It should work.


RE: Updating Interbase data in VC++

Updating is quite possible to do via consumer templates, but it depends greatly on the provider that you are using: most that I have encountered (especially the free ones) do not support updateable rowsets, so you are normally left only with pass-through to the server (=SQL statements).

One particularly problematic area with using plain commands is that you'll need to somehow manage your position: basically you are forced to preserve your primary key value in order to identify the row which you are updating; if you need to change the primary key, you'll have to do it by deletion-insertion procedure, but this can have unexpected repercussions, say due to foreign-key restrictions. With updateable recordsets, a savvy provider tracks the position automatically.
