faq {

I deleted a lot of data but the database file did not get any

smaller. Is this a bug?
|

} {
|
||||
<p>No. When you delete information from an SQLite database, the
|
||||
unused disk space is added to an internal "free-list" and is reused
|
||||
the next time you insert data. The disk space is not lost. But
|
||||
neither is it returned to the operating system.</p>
|
||||
|
||||
<p>If you delete a lot of data and want to shrink the database file,
|
||||
run the VACUUM command (version 2.8.1 and later). VACUUM will reconstruct
|
||||
the database from scratch. This will leave the database with an empty
|
||||
free-list and a file that is minimal in size. Note, however, that the
|
||||
VACUUM can take some time to run (around a half second per megabyte
|
||||
on the Linux box where SQLite is developed) and it can use up to twice
|
||||
as much temporary disk space as the original file while it is running.

||||

faq {

Can I use SQLite in my commerical product without paying royalties?
|
||||
} {
|
||||
<p>Yes. SQLite is in the public domain. No claim of ownership is made
|
||||
to any part of the code. You can do anything you want with it.</p>
