<p>The CREATE VIEW command assigns a name to a pre-packaged
<a href="lang_select.html">SELECT</a> statement.
Once the view is created, it can be used in the FROM clause
of another <a href="lang_select.html">SELECT</a> in place of a table name.
</p>
<p>If the "TEMP" or "TEMPORARY" keyword occurs in between "CREATE"
and "VIEW" then the view that is created is only visible to the
<a href="c3ref/sqlite3.html">database connection</a> that created it and is automatically deleted when
the database connection is closed.</p>
<p> If a <span class='yyterm'>schema-name</span> is specified, then the view
is created in the specified database.
It is an error to specify both a <span class='yyterm'>schema-name</span>
and the TEMP keyword on a VIEW, unless the <span class='yyterm'>schema-name</span>
is "temp".
If no schema name is specified, and the TEMP keyword is not present,
the VIEW is created in the main database.</p>
<p>You cannot <a href="lang_delete.html">DELETE</a>, <a href="lang_insert.html">INSERT</a>, or <a href="lang_update.html">UPDATE</a> a view. Views are read-only
in SQLite. However, in many cases you can use an
<a href="lang_createtrigger.html#instead_of_trigger">INSTEAD OF trigger</a> on the view to accomplish
the same thing. Views are removed
with the <a href="lang_dropview.html">DROP VIEW</a> command.</p>
<p>If a <span class='yyterm'>column-name</span> list follows
the <span class='yyterm'>view-name</span>, then that list determines
the names of the columns for the view. If the <span class='yyterm'>column-name</span>
list is omitted, then the names of the columns in the view are derived
from the names of the result-set columns in the <a href="syntax/select-stmt.html">select-stmt</a>.
Note that the <span class='yyterm'>column-name</span> list syntax is only
supported in SQLite versions 3.9.0 (2015-10-14) and later.
