Question: Why do I have very slow inserts of numerous records using Firebird (I have several hundred thousands of records)?
Answer: Please donít 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.
  • Try set : TpFibDataset.Unidirectional:=true; before open.
  • Try Use TpFibQuery
  • If on local PC use the local connection

Our 911 dispatch center needed a program to monitor the status of equipment used in emergency situations. If one dispatcher modified the status of a piece of equipment, all the other dispatchers needed to see this change immediately. The most elegant way to implement this was by using Firebird Events to asynchronously notify all the users whenever a pertinent change had occurred at the database server. After failing to implement this myself using the Firebird API, I bought a copy of FIBPlus. I dropped a Database, EventAlert and ErrorHandler control into a C++ Builder DataModule and within minutes I had all the functionality I needed. I was able to complete the project quickly and the users are thrilled with the results because I gave them more features than they originally asked for. >>
