<h2>SQL Features That SQLite Does Not Implement</h2>
|
||
|
|
|
||
|
|
<p>
|
||
|
|
SQLite implements most of the common features of SQL.
|
||
|
|
Rather than try to list all the features of SQL that SQLite does
|
||
|
|
support, it is much easier to list those that it does not.
|
||
|
|
Unsupported features of SQL are shown below.</p>
|
||
|
|
|
||
|
|
<p>
|
||
|
|

|
||
|
|
<a href="quirks.html">Quirks, Caveats, and Gotchas</a> of SQLite.

<table cellpadding="10">
|
||
|
|
|
||
|
|
<tr><td valign="top"><b><nobr>Complete ALTER TABLE support</nobr></b></td><td width="10"> </th><td valign="top">
|
||
|
|
Only the RENAME TABLE, ADD COLUMN, RENAME COLUMN, and DROP COLUMN
|
||
|
|
variants of the ALTER TABLE command are supported. Other kinds of
|
||
|
|
ALTER TABLE operations such as
|
||
|
|
ALTER COLUMN, ADD CONSTRAINT, and so forth are omitted.
|
||
|
|
</td></tr><tr><td valign="top"><b><nobr>Complete trigger support</nobr></b></td><td width="10"> </th><td valign="top">
|
||
|
|
FOR EACH ROW triggers are supported but not FOR EACH STATEMENT
|
||
|
|
triggers.
|
||
|
|
</td></tr><tr><td valign="top"><b><nobr>Writing to VIEWs</nobr></b></td><td width="10"> </th><td valign="top">
|
||
|
|
VIEWs in SQLite are read-only. You may not execute a DELETE, INSERT, or
|
||
|
|
UPDATE statement on a view. But you can create a trigger
|
||
|
|
that fires on an attempt to DELETE, INSERT, or UPDATE a view and do
|
||
|
|
what you need in the body of the trigger.
|
||
|
|
</td></tr><tr><td valign="top"><b><nobr>GRANT and REVOKE</nobr></b></td><td width="10"> </th><td valign="top">
|
||
|
|
Since SQLite reads and writes an ordinary disk file, the
|
||
|
|
only access permissions that can be applied are the normal
|
||
|
|
file access permissions of the underlying operating system.
|
||
|
|
The GRANT and REVOKE commands commonly found on client/server
|
||
|
|
RDBMSes are not implemented because they would be meaningless
|
||
|
|
for an embedded database engine.
