jak połączyć te dwa zapytania w jedno:

[SQL] pobierz, plaintext 
$sql =  "SELECT * FROM   object  
	INNER JOIN promocja  
	ON object.obId  = promocja.oglId 
	WHERE    promocja.obDateEnd  BETWEEN '".$_SESSION['data_po2']."' AND '".$_SESSION['data_ko2']."'  
	GROUP BY promocja.oglId";
[SQL] pobierz, plaintext 

z tym zapytaniem:

[SQL] pobierz, plaintext 
$sql = "SELECT a.*, b.*, c.*  
FROM object AS a, type AS b, state AS c  
WHERE a.obTypeId = b.typeId AND a.obStateId = c.stateId   AND a.obConfirm = '1' AND a.obDateEnd > NOW()";
[SQL] pobierz, plaintext 

http://pl.wikipedia.org/wiki/Operator_Union

Ale zanim zaczniesz czytać ten manual usuń gwiazdki z tych zapytań i wymień nazwy pobieranych pól

raczej UNION nie da rady, to by musialo tak wygladac ale to nie spełnia UNION bo tma pisze oba zapytania musza gnerowac taka sama ilosc kolumn, wiec to nie SPEŁNIA ZAŁOŻENIA.

więc UNION nie pasuje chyba że masz jakiś sposób na to ja jakoś tej zasady nie moge obejsc.

[SQL] pobierz, plaintext 
SELECT obId, obName, obStateId, obPriceOn, obConfirm, obDateEnd, obTypeId, obCity, obRoom, obTeren, obNearby
FROM object
INNER JOIN promocja ON object.obId = promocja.oglId
WHERE promocja.obDateEnd
BETWEEN '2012-08-01'
AND '2012-12-30'
GROUP BY promocja.oglId
 
 UNION 
 
SELECT a.obId, a.obName, a.obStateId, a.obPriceOn, a.obConfirm, a.obDateEnd,  a.obTypeId, a.obCity, a.obRoom, a.obTeren, a.obNearby,  b.typeId, 
typeName, typeNameen, typeNamedo, 
c.stateId,   c.stateName 
FROM object AS a, type AS b, state AS c  
WHERE a.obTypeId = b.typeId AND a.obStateId = c.stateId   AND a.obConfirm = '1' AND a.obDateEnd > NOW()
