with the [DROP VIEW] command.</p>

<p>^If a <yyterm>column-name</yyterm> list follows 
the <yyterm>view-name</yyterm>, then that list determines
the names of the columns for the view.  ^If the <yyterm>column-name</yyterm>
list is omitted, then the names of the columns in the view are derived
from the names of the result-set columns in the [select-stmt].










Note that the <yyterm>column-name</yyterm> list syntax is only
supported in SQLite versions 3.9.0 ([dateof:3.9.0]) and later.

with the [DROP VIEW] command.</p>

<p>^If a <yyterm>column-name</yyterm> list follows 
the <yyterm>view-name</yyterm>, then that list determines
the names of the columns for the view.  ^If the <yyterm>column-name</yyterm>
list is omitted, then the names of the columns in the view are derived
from the names of the result-set columns in the [select-stmt].
The use of <yyterm>column-name</yyterm> list is recommended.  Or, if
<yyterm>column-name</yyterm> list is omitted, then the result
columns in the [SELECT] statement that defines the view should have
well-defined names using the 
"[result-column|AS column-alias]" syntax.
SQLite allows you to create views that depend on automatically 
generated column names, but you should avoid using them since the 
rules used to generate column names are not a defined part of the
interface and might change in future releases of SQLite.

<p>The <yyterm>column-name</yyterm> list syntax was added in
SQLite versions 3.9.0 ([dateof:3.9.0]).
