I have two tables in my database, schema below:
user:
id: ~
email_id: { type: varchar(100), required: true }
password: { type: varchar(50), required: true }
display_name: { type: varchar(100) }
about_yourself: { type: longvarchar }
web_url: { type: varchar(500) }
last_active: { type: timestamp }
created_at: ~
updated_at: ~
is_active: { type: tinyint, default: 2 }
article:
id: ~
title: { type: varchar(400), required: true }
url_slug: { type: varchar(200), required: true }
user_id: { type: integer, foreignReference: id,
foreignTable: user, required: true, onDelete: cascade }
content: { type: longvarchar, required: true }
created_at: ~
updated_at: ~
is_active: { type: boolean, default: 1 }
=-=================
Now, I want the list of the 5 authors who have wriiten most active
articles.
For That purpose, I wrote the code in the UserPeer Class:
public static function getTopContributedAuthors($limit=5,
$criteria=null)
{
$criteria = new Criteria();
$criteria->addAsColumn('user_id', ArticlePeer::USER_ID);
$criteria->addAsColumn('number_of_articles',
'count(article.id)');
$criteria->addAsColumn('display_name', self::DISPLAY_NAME);
$criteria->addAsColumn('about_yourself',
self::ABOUT_YOURSELF);
$criteria->addGroupByColumn('user_id');
$criteria->addDescendingOrderByColumn('number_of_articles');
$criteria->add(ArticlePeer::IS_ACTIVE, 1);
$criteria->setLimit($limit);
$criteria->addJoin(self::ID, ArticlePeer::USER_ID,
Criteria::RIGHT_JOIN);
return self::doSelect($criteria);
}
==========
But, this gives me error:
500 | Internal Server Error | PropelException
[wrapped: SQLSTATE[42000]: Syntax error or access violation: 1064 You
have an error in your SQL syntax; check the manual that corresponds to
your MySQL server version for the right syntax to use near 'RIGHT JOIN
article ON (user.ID=article.USER_ID) WHERE article.IS_ACTIVE=1 GROUP '
at line 1]
and
if, I remove the line "$criteria->add(ArticlePeer::IS_ACTIVE, 1);",
It is giving me Notice:
Notice: Undefined offset: 6 in D:\xampp\htdocs\myarticles\lib\model\om
\BaseUser.php on line 1227
I guess that there is some issue in join. Can anybody please help to
identify the issue?
