Question

I’m using Symfony Project 1.4 and Postgresql

I got error query in doctrine using

$q = Doctrine_Query::create()
 ->select("count(sex) as total, sex")
 ->from('Biodata')
 ->groupBy('sex')           
 ->execute();

there is always display error like this when debug:

SQLSTATE[42803]: Grouping error: 7 ERROR: column "e.id" must appear in the GROUP BY clause or be used in an aggregate function
LINE 1: SELECT e.id AS e__id, e.sex AS e__sex, COUNT(e.sex) AS e__0 ...
^. Failing Query: "SELECT e.id AS e__id, e.sex AS e__sex, COUNT(e.sex) AS e__0 FROM biodata e GROUP BY e.sex"

How to fix it and hide e.id column, is this bugs or need a trick?

Excepted result:

Answer 1

Doctrine automatically add the primary key to the select list. We’ve got the same error using MSSQL.

Try to add not hydrate result:

$q = Doctrine_Query::create()
 ->setHydrationMode(Doctrine_Core::HYDRATE_NONE)
 ->select("count(sex) as total, sex")
 ->from('Biodata')
 ->groupBy('sex')
 ->execute();

You won’t have column name, but something like this I think:

+========+=========+
|   0    |    1    |
+========+=========+
|  183   |    1    |
+--------+---------+
|   54   |    2    |
+========+=========+
