Where statement with OR doesn't work

Hi and thank you in advance for your help

I have two tables 

Match

Team

And I have a problem with this code: 

// load records
list($teamRecords, $teamMetaData) = getRecords(array(
'tableName' => 'team',
'where' => whereRecordNumberInUrl(1),
'limit' => '1',
));
$teamRecord = @$teamRecords[0]; // get first record

// load records
list($matchRecords, $matchMetaData) = getRecords(array(
'tableName' => 'match',
'where' => "team_home =".intval($squadreRecord['num']) or "team_away =".intval($squadreRecord['num']),
'orderBy' => 'date_match ASC',
));

It works only with one team, but doesn't work when i put team_away OR team_home in where statement.

Could youl help me?
