<p>
|
|
|
|
|
Though still relatively new,
|
|
|
|
|
the SQLite code base appears to be working well and has therefore
|
|
|
|
|
been upgraded to "beta" status.
|
|
|
|
|
There are currently no known errors in the code.
|
2000-06-01 04:03:43 +04:00
|
|
|
One very large database (1M+ records in 50+ separate tables) has
|
|
|
|
|
been converted from PostgreSQL and gives every appearance of working
|
2000-06-02 17:27:59 +04:00
|
|
|
correctly.</p>

|
|
|
|
|
|
2000-06-02 17:27:59 +04:00
|
|
|
<p>SQLite is an SQL database built atop the
|
|
|
|
|
<a href="http://www.gnu.org/software/gdbm/gdbm.html">GDBM library</a>.
|
|
|
|
|
The SQLite distribution includes both a interactive command-line
|
|
|
|
|
access program (<b>sqlite</b>) and a C library (<b>libsqlite.a</b>)
|
|
|
|
|
that can be linked
|
|
|
|
|
with a C/C++ program to provide SQL database access without having
|
|
|
|
|
to rely on an external RDBMS.</p>
|
2000-05-29 21:44:25 +04:00
|
|
|
|
|
|
|
|
<p>The C interface to SQLite is very simple, consisting of only
|
2000-06-02 17:27:59 +04:00
|
|
|
four functions, a single opaque data structure, and a handful of
|
|
|
|
|
constants that define error return codes.
|
2000-05-29 22:20:15 +04:00
|
|
|
See <a href="c_interface.html">c_interface.html</a> for details.
|
|
|
|
|
A Tcl interface
|
2000-05-29 21:44:25 +04:00
|
|
|
to SQLite is also available and is included in the source tree.
|
2000-05-29 22:20:15 +04:00
|
|
|
Documentation on the Tcl interface is pending.
|
2000-05-29 21:44:25 +04:00
|
|
|
Interfaces for perl and python may be supplied in future releases.</p>
|
|
|
|
|
|
2000-06-02 17:27:59 +04:00
|
|
|
<p>The standalone program <b>sqlite</b> can be used
|
2000-05-29 21:44:25 +04:00
|
|
|
to interactively create, update and/or query an SQLite database.
|
|
|
|
|
The sources to the sqlite program are part of the source tree and
|
|
|
|
|
can be used as an example of how to interact with the SQLite C
|
2000-05-29 22:20:15 +04:00
|
|
|
library. For more information on the sqlite program,
|
|
|
|
|
see <a href="sqlite.html">sqlite.html</a>.</p>

<p>SQLite is intended to be small and light-weight.
|
|
|
|
|
It does not try to implement every feature of SQL.
|
2000-05-31 19:34:51 +04:00
|
|
|
A few of the many SQL features that SQLite does not (currently)
|
2000-05-29 22:20:15 +04:00
|
|
|
implement are as follows:</p>
|
2000-05-29 21:44:25 +04:00
|
|
|
|
|
|
|
|
<p>
|
|
|
|
|
<ul>
|
|
|
|
|
<li>The GROUP BY or HAVING clauses of a SELECT</li>
|
|
|
|
|
<li>Constraints</li>
|
2000-05-29 22:20:15 +04:00
|
|
|
<li>Nested queries</li>
|
2000-05-29 21:44:25 +04:00
|
|
|
<li>Transactions or rollback</li>

<H2>Status</h2>
|
|
|
|
|
|
2000-06-01 04:03:43 +04:00
|
|
|
<p>The SQLite code is rapidly stablizing. There are currently
|
|
|
|
|
no known errors in the code. At least one large database has
|
|
|
|
|
be loaded into SQLite and appears to work. Most of the major
|
|
|
|
|
functionality is in place.</p>
|
2000-05-29 21:44:25 +04:00
|
|
|
|
|
|
|
|
<p>SQLite has so far been tested only on RedHat 6.0 Linux. But we
|
|
|
|
|
know of no reason why it will not work on any other Unix platform,
|
|
|
|
|
or on Windows95/98/NT.</p>
