Problem with MS Access - deleting records...
Hi,
I have this app that interacts with an MS Access table in an mdb file. I added some 5k records and the size of the mdb file shows up as 300Kb.....then I deleted all the records.....still the size remanins the same!! I again added another 5K records and the size went up to 600Kb !! I again delete the records ...but the size remains the same!! Ne idea why this is happening?
Pssst...just try it out on ur system....am sure u'll face the same problem......just create a table manually.....add records...chk the size...delete the records and chk the size again!

That's very simple, MS ACCESS (and all other DBMS i know) don't rfree storage after delete. Normaly, that's an request directed to a file system but not to a DBMS.

There is a option in MSAccess to compact you database, as Onegazhang suggest ... but you can do it using the command line prompt
<path to>msaccess.exe <path to>yourbackend.mdb /compact
this should work. But be warned that it can be a lengthy process depending on the size of you mdb file, and lengthier if the databse is on the network.

The compacting option using MSAccess can be found under the tools->utilities->Compacti

Hi,
Thanks all for those replies. Thing is that i am doing this 'programatically'. So even though i selected the compact database option I am just doing an OpenConnection using ADO Connection object.
Neways, I figured that I can create a macro inside the mdb that will trigger the compact database command. Now I need to fire this macro from within my code. Any idea how to fire a macro from code?
