Executing a MySQL stored procedure

It took me quite some time but here is how to execute a MySQL stored procedure.

$connection = Propel::getConnection();
 
$query = 'CALL Proc(%s, %s, %s)';    
$query = sprintf($query, $var1, $var2, $var3);
 
$mysqli = $connection->getResource();
if($mysqli->multi_query($query)){
  do{
    if($result = $mysqli->use_result()){
      while($row = $result->fetch_assoc()){
        //
      }
      $result->free();
    }
  } while(($mysqli->next_result()));
}
 

Note that you should be using mysqli in order for this to work properly.

propel behavior to extend classes with separate tables

I needed to have many subclasses inherited from a main class.

To do that with propel, you need to have all your classes in one big table. I wanted to have separate tables.

Then I discovered the propel behaviors and it does that very well !

Let's see an example with a master class "element" and a subclass "subElement" :

Retrieve model objects with custom SQL query

$sql = 'select * from ( select * from book order by weight desc limit 5 ) as T order by popularity';
$connection = Propel::getConnection();
$statement = $connection->createStatement(  );
$result = $statement->executeQuery( $sql , ResultSet::FETCHMODE_NUM);
return BookPeer::populateObjects( $result );

foreignkey to sf_guard_user

if you won´t to add a foreignkey to sf_guard_user put this on top off you schema.yml file ;)

propel:
  _attributes :          { package: "plugins.sfGuardPlugin.lib.model" }
  sf_guard_user:
    _attributes:         { phpName: sfGuardUser }
    id:

now you can simple add a foreignkey

propel:
  tbl_user_profile:
    user_id:             { type: integer, primaryKey: true, foreignTable: sf_guard_user, foreignReference: id, onDelete: cascade }

or

propel:
  tbl_user_profile:
    sf_guard_user_id:

Autosetting Created_by and Updated_by fields in all models

Propel can create Models with autoset created_at and Updated_at field, but dont include autoset for Created_by and Updated_by field, because this fields are most aplication dependent. We can set Propel to build models with autossetting Created_by and Updated_by fields (ao any other fields) extending SfObjectBuilder. In the forum message 7535 Tamcy give us a good example. Here I post a SFObjectBuilder extension class (in this example I check if using SfGuardPlugin for user Class).

<?php
/* I recomend put this class out Symfony Folder.
*  If you put this class in some project folder
* you can use include_once 'symfony.addon.propel.builder.SfObjectBuilder.php'
require_once 'sfObjectBuilder.php';
* @author     Boris Duin 
 */
class SfObjectAdvBuilder extends SfObjectBuilder
{
  */Extend Method addSave
  protected function addSave(&$script)
  {
    $tmp = '';
    parent::addSave($tmp);
 
    $date_script = '';
 
    $user_updated = false;
    $user_created = false;
    foreach ($this->getTable()->getColumns() as $col)
    {
      $clo = strtolower($col->getName());
 
      if (!$user_created && $clo == 'created_by')
      {
        $user_created = true;
        $date_script .= "
    if (\$this->isNew() && !\$this->isColumnModified('created_by'))
    {
      \$user = sfContext::getInstance()->getUser();
      if (\$user instanceof sfGuardSecurityUser)
        \$this->setCreatedby(\$user->getUsername())
    }
";
      }
      else if (!$user_updated && $clo == 'updated_by')
      {
       $user_updated = true;
        $date_script .= "
    if (\$this->isModified() && !\$this->isColumnModified('updated_by'))
    {
      \$user = sfContext::getInstance()->getUser();
      if (\$user instanceof sfGuardSecurityUser)
        \$this->setUpdatedby(\$user->getUsername())
    }
";
      }
    }
 
    $tmp = preg_replace('/{/', '{'.$date_script, $tmp, 1);
    $script .= $tmp;
  }
}

Note: I write this class for synfony 0.9.x versión. Yesterday I was refactoring this class for 1.0.x version, but I leave this in my house, :(. To set propel to use this class you must edit config/propel.ini. Replace this line

for

Example: If you put this class in your Project/Lib folder you can set the line:

Now, when you run symfony propel-build-model, propel will use this class and add autoset code for created_by and Updated_by field. Here an example of models class generated by propel:

public function save($con = null)
    {
    if ($this->isNew() && !$this->isColumnModified('created_by'))
    {
      $user = sfContext::getInstance()->getUser();
      if ($user instanceof sfGuardSecurityUser)
        $this->setCreatedby($user->getUsername());
    }
 
    if ($this->isNew() && !$this->isColumnModified('created_at'))
    {
      $this->setCreatedAt(time());
    }
 
    if ($this->isModified() && !$this->isColumnModified('updated_by'))
    {
      $user = sfContext::getInstance()->getUser();
      if ($user instanceof sfGuardSecurityUser)
        $this->setUpdatedby($user->getUsername());
    }
 
    if ($this->isModified() && !$this->isColumnModified('updated_at'))
    {
      $this->setUpdatedAt(time());
    }

Complement complex SQL in SYMFONY

complement complex SQL in SYMFONY:

Example 1: SQL to be implemented:

SELECT b.id FROM article_mark a RIGHT JOIN article b ON a.article_id = b.id ORDER BY a.mark DESC,b.CREATED_AT DESC

Symfony implementation:

    $c=new Criteria();
    $c->addAlias('a', 'article_mark');              //!!!if not using alias of table, the generated sql is not correct
    $c->addAlias('b', 'article');
    $c->addSelectColumn('b.id');
    $c->addSelectColumn('a.article_id');            //!!!if one table has no column added, there's no table name after FROM clause;; actually this column is not what I need
    $c->addDescendingOrderByColumn('a.mark');
    $c->addDescendingOrderByColumn('b.CREATED_AT');
    $c->addJoin('a.ARTICLE_ID','b.ID','RIGHT JOIN');
    $art_marks=ArticlePeer::doSelectRS($c);         //!!! doSelect or doSelectOne can't be used

By this way, $art_marks is a MySQL recordset, using $art_marks[0] get value of column b.id;

Example 2: SQL to be implemented:

select SUM(score) from bury group by article_id having article_id=@ARTICLE_ID

Symfony implementation:

        $c=new Criteria();
        $c->addSelectColumn('SUM(score) as A');     //actually 'as A' has no use
        $c->addSelectColumn(BuryPeer::SCORE);              //!! without this, no table name in generated sql; actually this column is not what I need
 
        $c->addGroupByColumn('article_id');
        $crit=$c->getNewCriterion(BuryPeer::ARTICLE_ID,$article->getId());
        $c->addHaving($crit);
        $buries=BuryPeer::doSelectRS($c);       //only MySQL recordset can be used

Using multiple databases from Propel

if you using multiple database from Propel, It can be solve by writing two or more schema files.

PROJECT_DIR/config/databases.yml

all:
  database1:
    class:   sfPropelDatabase
    param:
      dsn:   pgsql://foo:bar@hostname/database1

  database2:
    class:   sfPropelDatabase
    param:
      dsn:   mysql://foo:bar@hostname/database2

PROJECT_DIR/config/database1.schema.xml

<?xml version="1.0" encoding="UTF-8"?>
<database name="database1" defaultIdMethod="native" noxsd="true">
　　<table name="foo" phpName="Foo">
    ....
　　</table>
</database>

PROJECT_DIR/config/database2.schema.xml

<?xml version="1.0" encoding="UTF-8"?>
<database name="database2" defaultIdMethod="native" noxsd="true">
　　<table name="bar" phpName="Bar">
    ....
　　</table>
</database>

Last, build model command.

$ symfony propel-build-model

Build complete.

Example, getting multiple databases connection handler.

$database1_connection_handler = Propel::getConnection(FooPeer::DATABASE_NAME);
$database2_connection_handler = Propel::getConnection(BarPeer::DATABASE_NAME);
