Zend DB Select with multiple table joins

Trying to replicate the following query using Zend_Db_Select. Any pointers?

SELECT 
  compounds.id as compounds_id,
  reactions.id as reactions_id, 
  reaction_compound.number as reaction_compound_number  
FROM compounds, reactions, reaction_compound 
WHERE  
  compounds.id IN (68,74,112) 
  AND compounds.id = reaction_compound.compound  
  AND reactions.id = reaction_compound.reaction;

Specifically some issues I'm running into are doing multiple table joins in Zend. I'm not sure how to do the join acros开发者_StackOverflow社区s multiple tables using their query builder.

Any help is appreciated!

Something the likes of:

$compoundIds = array(68,74,112);
$select = $db->select()
   ->from('compounds', array('compounds_id' => 'id')
   ->where('compounds.id in ( ? )', $compoundIds)
   ->join('reaction_compound', 'compounds.id = reaction_compound.compound', array('reaction_compound_number' => 'number'))
   ->join('reactions', 'reactions.id = reaction_compound.reaction', array('reaction_id' => 'id');

That should get you somewhere. I didn't test it, so there might be some errors in there.

The format:

$db->select()->from('table_name')->join('...')->join('...')

Works great!
Thank both of you posters for this info! Helped me solve quite a doozy! (Abstract Table Models oh my!!) Lol

Ps: To others about to utilize the same format detailed above remember that column names will be overwritten by latter tables with same column names. Happy Coding!
