<br>
<p class="p__0">3. How VACUUM works The VACUUM command works by copying the contents of the database into a momentary database file and then overwriting the initial with the contents of the short-lived file. When overwriting the original, a rollback journal or write-ahead log WAL file is used just as it would be for any other database transaction.</p>

<p class="p__1">The VACUUM INTO command works the exact same method other than that it utilizes the file named on the INTO clause in place of the short-term database and leaves out the action of copying the vacuumed database back over top of the original database. The VACUUM command might change the ROWIDs of entries in any tables that do not have a specific INTEGER PRIMARY SECRET.</p>
<br>
<p class="p__2">Unfinalized SQL declarations typically hold a checked out transaction open, so the VACUUM might fail if there are unfinalized SQL statements on the very same connection. VACUUM (however not VACUUM INTO) is a compose operation therefore if another database connection is holding a lock that avoids composes, then the VACUUM will fail.</p>

<br>
<p class="p__3">When auto_vacuum is enabled for a database totally free pages may be reclaimed after erasing data, triggering the file to shrink, without rebuilding the entire database utilizing VACUUM. However, using auto_vacuum can cause additional database file fragmentation. And auto_vacuum does not compact partly filled pages of the database as VACUUM does.</p>
