    <p>I'm struggling with retreiving data in propel 1.6.7.</p> <p>Here's the sample of query I want to achieve:</p> <pre><code>select count(1) as amount, p1.local_id FROM panel_data pd JOIN panel_data_has_code pp1 on (pd.panel_data_id = pp1.panel_data_id) JOIN panel_code p1 on (pp1.panel_code_id = p1.panel_code_id AND p1.type='equipment' AND model_id = 'my_model_id') JOIN panel_data_has_code pp2 on (pd.panel_data_id = pp2.panel_data_id) JOIN panel_code p2 on (pp2.panel_code_id = p2.panel_code_id AND p2.type='model' AND p2.local_id='my_local_id') GROUP BY p1.local_id </code></pre> <p>However whenever I try to construct proper criteria in Propel ORM, I'm having an issue - apparently propel always translate join alias to table name, whenever I try to use add join condition or use alias in select method. I've replaced multiple join condition with simple <code>filterBy</code> method (I always use inner joins, so effect will be the same), but I'm still having issue with retreiving groupped column (p1.local_id).</p> <p>Here's the code I work with atm:</p> <pre><code>PanelDataQuery::create() -&gt;select(array( 'p1.localId')) -&gt;withColumn('count(1)', 'amount') -&gt;usePanelDataHasCodeQuery('pp1')-&gt;usePanelCodeQuery('p1')-&gt;groupByLocalId()-&gt;filterByType($type)-&gt;endUse()-&gt;endUse() -&gt;usePanelDataHasCodeQuery('pp2')-&gt;usePanelCodeQuery('p2')-&gt;filterByType('model')-&gt;filterByLocalId($model)-&gt;endUse()-&gt;endUse() -&gt;find(); </code></pre> <p>Above statement returns an error:</p> <blockquote> <p>Unable to execute SELECT statement [SELECT count(1) AS amount, panel_code.LOCAL_ID AS \"p1.localId\" FROM panel_data INNER JOIN panel_data_has_code pp1 ON (panel_data.PANEL_DATA_ID=pp1.PANEL_DATA_ID) INNER JOIN panel_code p1 ON (pp1.PANEL_CODE_ID=p1.PANEL_CODE_ID) INNER JOIN panel_data_has_code pp2 ON (panel_data.PANEL_DATA_ID=pp2.PANEL_DATA_ID) INNER JOIN panel_code p2 ON (pp2.PANEL_CODE_ID=p2.PANEL_CODE_ID) WHERE p1.TYPE=:p1 AND p2.TYPE=:p2 AND p2.LOCAL_ID=:p3 GROUP BY p1.LOCAL_ID] [wrapped: SQLSTATE[42000]: [Microsoft][SQL Server Native Client 11.0][SQL Server]The multi-part identifier \"panel_code.LOCAL_ID\" could not be bound.]</p> </blockquote> <p>Obviously, select clause causes the problem. Any ideas how to force propel to use table alias instead of translating it to table name?</p> <p>Thank you in advance for any help.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
