Question:
Why do I have very slow inserts of
numerous records using Firebird (I have several hundred thousands of
records)?
Answer:
Please don’t use TpFIBDataset, because this is a buffered
dataset. You will also have memory problems with TpFIBDataset. Use
pFIBQuery with parameterized inserts instead. A commit after 500 should
be ok. We made a text-import component and are able to put 100.000
records in 4 seconds with this approach.
Tips:
- Try set : TpFibDataset.Unidirectional:=true; before open.
- Try Use TpFibQuery
- If on local PC use the local connection
We use FIBPlus in all our applications, and we're very satisfied. If you're coming from IBX, FIBPlus is an especially good choice in as much as it has a common origin, and therefore, a similar structure, so conversion from IBX to FIBPlus is rather easy. >>Jonathan Neve, Microtech, France
