|

The file format used changed beginning with version 2.0.0. Version 1.0.X
|
||||
of SQLite used GDBM as its database backend. Version 2.0.0 and later
|
||||
use a built-in implementation of B-trees. If you have older 1.0 databases
|
||||
you will need to convert them before they can be read using a 2.0
|
||||
release of SQLite. The following command will convert a legacy
|
||||
database into the new 2.0 format:
|
||||
The SQLite file format changed beginning with version 2.1.0. The
|
||||
same basic B-Tree structure from version 2.0.0 is used but the
|
||||
details of indices where altered to permit better query optimization
|
||||
and the B-Tree table entry headers where changed slightly to expand the
|
||||
maximum amount of data on a row from 64KB to 16MB.
|
||||
The file format changes
|
||||
between 2.0.8 and 2.1.0 are small but they still require that you
|
||||
dump and restore your old databases. The following command should
|
||||
suffice:
|
||||
</p>
|
||||
|
||||
<blockquote><pre>
|
||||
echo .dump | sqlite1.0 old.db | sqlite2.0 new.db
|
||||
echo .dump | sqlite2.0 old.db | sqlite2.1 new.db
|
||||
</pre></blockquote>
|
||||
|
||||
<p>
|
||||
The above command assumes that <b>sqlite1.0</b> is sqlite version 1.0
|
||||
and <b>sqlite2.0</b> is sqlite version 2.0. The old database is stored
|
||||
in a directory named <b>old.db</b> and the new database is created in
|
||||
the file <b>new.db</b>.
|
||||
The above command assumes that <b>sqlite2.0</b> is any of the
|
||||
2.0 series of sqlite command-line tools and <b>sqlite2.1</b> is the
|
||||
new version 2.1 sqlite command-line tool.
|
||||
</p>
|
||||
|
||||
<p>
|
||||
Version 1.0.X of SQLite used GDBM as its backend and so its
|
||||
file format is complete incompatable with all version 2.0 and
|
||||
version 2.1 SQLite releases. Legacy databases must be dumped to
|
||||
ASCII and reloaded, as shown above, before they can be used with
|
||||
newer versions of SQLite.
