Can multiple applications or multiple instances of the same

application access a single database file at the same time?
|
||||
} {
|
||||
<p>Multiple processes can have the same database open at the same
|
||||
time. On unix systems, multiple processes can be doing a SELECT
|
||||
at the same time. But only one process can be making changes to
|
||||
the database at once. On windows, only a single process can be
|
||||
reading from the database at one time since Win95/98/ME does not
|
||||
support reader/writer locks.</p>
|
||||
|
||||
<p>The locking mechanism used to control simultaneous access might
|
||||
not work correctly if the database file is kept on an NFS filesystem.
|
||||
You should avoid putting SQLite database files on NFS if multiple
|
||||
processes might try to access the file at the same time.</p>
|
||||
|
||||
<p>Locking in SQLite is very course-grained. SQLite locks the
|
||||
entire database. Big database servers (PostgreSQL, MySQL, Oracle, etc.)
|
||||
generally have finer grained locking, such as locking on a single
|
||||
table or a single row within a table. If you have a massively
|
||||
parallel database application, you should consider using a big database
|
||||
server instead of SQLite.</p>
|
||||
|
||||
<p>When SQLite tries to access a file that is locked by another
|
||||
process, the default behavior is to return SQLITE_BUSY. You can
|
||||
adjust this behavior from C code using the <b>sqlite_busy_handler()</b> or
|
||||
<b>sqlite_busy_timeout()</b> API functions. See the API documentation
|
||||
for details.</p>

Is SQLite threadsafe?
|
||||
} {
|
||||
<p>Almost. In the source file named "<b>os.c</b>" there are two functions
|
||||
named <b>sqliteOsEnterMutex()</b> and <b>sqliteOsLeaveMutex()</b>. In
|
||||
the default distribution these functions are stubs. They do not do anything.
|
||||
If you change them so that they actually implement a mutex, then SQLite
|
||||
will be threadsafe. But because these routines are stubs, the default
|
||||
SQLite distribution is not threadsafe.</p>
|
||||
}
|
||||
|
||||
faq {
|
||||
How do I list all tables/indices contained in an SQLite database
|
||||
} {
|
||||
<p>If you are running the <b>sqlite</b> command-line access program
|
||||
you can type "<b>.tables</b>" to get a list of all tables. Or you
|
||||
can type "<b>.schema</b>" to see the complete database schema including
|
||||
all tables and indices. Either of these commands can be followed by
|
||||
a LIKE pattern that will restrict the tables that are displayed.</p>
|
||||
|
||||
<p>From within a C/C++ program (or a script using Tcl/Ruby/Perl/Python
|
||||
bindings) you can get access to table and index names by doing a SELECT
|
||||
on a special table named "<b>SQLITE_MASTER</b>". Every SQLite database
|
||||
has an SQLITE_MASTER table that defines the schema for the database.
|
||||
The SQLITE_MASTER table looks like this:</p>
|
||||
<blockquote><pre>
|
||||
CREATE TABLE sqlite_master (
|
||||
type TEXT,
|
||||
name TEXT,
|
||||
tbl_name TEXT,
|
||||
rootpage INTEGER,
|
||||
sql TEXT
|
||||
);
|
||||
</pre></blockquote>
|
||||
<p>For tables, the <b>type</b> field will always be <b>'table'</b> and the
|
||||
<b>name</b> field will be the name of the table. So to get a list of
|
||||
all tables in the database, use the following SELECT command:</p>
|
||||
<blockquote><pre>
|
||||
SELECT name FROM sqlite_master
|
||||
WHERE type='table'
|
||||
ORDER BY name;
|
||||
</pre></blockquote>
|
||||
<p>For indices, <b>type</b> is equal to <b>'index'</b>, <b>name</b> is the
|
||||
name of the index and <b>tbl_name</b> is the name of the table to which
|
||||
the index belongs. For both tables and indices, the <b>sql</b> field is
|
||||
the text of the original CREATE TABLE or CREATE INDEX statement that
|
||||
created the table or index. For automatically created indices (used
|
||||
to implement the PRIMARY KEY or UNIQUE constraints) the <b>sql</b> field
|
||||
is NULL.</p>
|
||||
|
||||
<p>The SQLITE_MASTER table is read-only. You cannot change this table
|
||||
using UPDATE, INSERT, or DELETE. The table is automatically updated by
|
||||
CREATE TABLE, CREATE INDEX, DROP TABLE, and DROP INDEX commands.</p>
|
||||
|
||||
<p>Temporary tables do not appear in the SQLITE_MASTER table. At this time
|
||||
there is no way to get a listing of temporary tables and indices.</p>
