Alias in select and having

i have query

$q = Doctrine_Query::create()
->select('g.,gp.,st.,np.,v.,s.,max(gp.card_date) as md')
->from('gragdans as g')
->innerJoin('g.Pribs_ gp')
->leftJoin('gp.Streets_ st')
->leftJoin('gp.Viddocs_ v')
->leftJoin('gp.Sobits_ s')
->leftJoin('st.Npunkts_ np')
->where('g.grid in '.$idlst,1)
->orderby('fam')
->having('gp.card_date=md');

When it runs i have error:

<b>Fatal error</b>: Uncaught exception
'Doctrine_Connection_Mysql_Exception' with message 'SQLSTATE[42S22]:
Column not found: 1054 Unknown column 'md' in 'having clause'' in Z:
\home\new\www\system\application\plugins\doctrine\lib\Doctrine
\Connection.php:1082

SQL for it looks like:

SELECT g.grid AS g_grid, g.fam AS gfam, g.nam AS g_nam, g.otc AS
g_otc, g.date_rogd AS gdate_rogd, g.gosgrid AS g_gosgrid,
g.rogd_place AS g_rogd_place, g.pol AS g_pol, g.reg_date AS
g_reg_date, g.deesp AS gdeesp, p.pribid AS p_pribid, p.grid AS
p_grid, p.strid AS pstrid, p.hom AS phom, p.cor AS p_cor, p.kva
AS p_kva, p.reg_date AS preg_date, p.vidid AS p_vidid, p.pas_ser
AS p_pas_ser, p.pas_no AS ppas_no, p.org_name AS p_org_name,
p.pas_date AS p_pas_date, p.sobid AS p_sobid, p.reg_expire AS
p_reg_expire, p.card_date AS pcard_date, s.strid AS s_strid,
s.npid AS s_npid, s.name AS sname, v.vidid AS v_vidid, v.name AS
v_name, s2.sobid AS s2sobid, s2.cod_s AS s2_cod_s, s2.cod_oi AS
s2_cod_oi, s2.name AS s2name, n.npid AS nnpid, n.name AS n_name,
n.sid AS n_sid, MAX(p.card_date) AS p_0 FROM gragdans g INNER JOIN
prib p ON g.grid = p.grid LEFT JOIN streets s ON p.strid = s.strid
LEFT JOIN viddoc v ON p.vidid = v.vidid LEFT JOIN sobit s2 ON p.sobid
= s2.sobid LEFT JOIN npunkt n ON s.npid = n.npid WHERE (g.grid in (4,
13, 19, 20)) HAVING p.card_date=md ORDER BY g.fam

But i need Query looks like:

SELECT g.grid AS g_grid, g.fam AS gfam, g.nam AS g_nam, g.otc AS
g_otc, g.date_rogd AS gdate_rogd, g.gosgrid AS g_gosgrid,
g.rogd_place AS g_rogd_place, g.pol AS g_pol, g.reg_date AS
g_reg_date, g.deesp AS gdeesp, p.pribid AS p_pribid, p.grid AS
p_grid, p.strid AS pstrid, p.hom AS phom, p.cor AS p_cor, p.kva
AS p_kva, p.reg_date AS preg_date, p.vidid AS p_vidid, p.pas_ser
AS p_pas_ser, p.pas_no AS ppas_no, p.org_name AS p_org_name,
p.pas_date AS p_pas_date, p.sobid AS p_sobid, p.reg_expire AS
p_reg_expire, p.card_date AS pcard_date, s.strid AS s_strid,
s.npid AS s_npid, s.name AS sname, v.vidid AS v_vidid, v.name AS
v_name, s2.sobid AS s2sobid, s2.cod_s AS s2_cod_s, s2.cod_oi AS
s2_cod_oi, s2.name AS s2name, n.npid AS nnpid, n.name AS n_name,
n.sid AS n__sid, MAX(p.card_date) AS md FROM gragdans g INNER JOIN
prib p ON g.grid = p.grid LEFT JOIN streets s ON p.strid = s.strid
LEFT JOIN viddoc v ON p.vidid = v.vidid LEFT JOIN sobit s2 ON p.sobid
= s2.sobid LEFT JOIN npunkt n ON s.npid = n.npid WHERE (g.grid in (4,
13, 19, 20)) group by fam HAVING p.card_date=md

This query run fine and give me what i need.

Doctrine dont use 'md' alias instead it convert it to 'p__0'
