Question : Quickly add records to large database

Hello, I have written a program that must log records to a database every three seconds (44 fields of numeric data). Sometimes we must log for days on end, sometimes just a few hours here and there. We want to keep a few months of history as we go. As time goes on and the record count adds up, the process of adding a record takes longer and longer causing general program instability. It seems there are definitely some issues to consider when trying to add a record to a table containing hundreds of thousands of records. At some point I suppose the table must be archived and a new one started but I’m not sure where the practical limit is.

Being an old timer, I am using DAO.  I’ve had issues in the past when dimming global recordsets so what I do is set the recordset in the procedure every time with an SQL statement (Select * FROM…), use the AddNew method then update and close. This process was taking 12 seconds, which of course blows the whole point of logging every three seconds so I started over with a blank table and now the process completes in the blink of an eye again.

Does anyone have any suggestions (other than a new table) for adding records and avoiding this slowdown?

Answer : Quickly add records to large database

1) Billystyx has a great idea...try it
2) Change your recordset SQL to something like this:
     SELECT * FROM MyTable WHERE 1=0
    This will allow you full access to the table structure for the purpose of your recordset, but will return no records.  Should be much quicker.
3) Use a dynamic INSERT with CurrentDB.Execute instead of generating a recordset.  Much quicker results all around.
