[SOLVED] SQL help

Hi guys,

 

I was wondering,

I have this MYSQL Select code:

SELECT * FROM `schedule`  WHERE `month` = '12 'AND `year`='2009' AND `home_team`='16' OR `away_team`='16' ORDER BY `day` ASC

 

It shows results from every month and every year...

 

Why is that? The only 2 thing that it takes into consideration is the home_team and away_team and the Order By....

Hi

 

Problem is down to the precedence of AND and OR.

 

MySQL evaluates the ANDs first and then the OR. Use brackets to force the issue:-

 

SELECT *

FROM `schedule` 

WHERE `month` = '12 '

AND `year`='2009'

AND (`home_team`='16'

OR `away_team`='16' )

ORDER BY `day` ASC

 

All the best

 

Keith
