drupal - Drupal 7 OR 条件与一系列 AND 条件

Question

我有一个如下所示的`Drupal 查询

$qry = db_select('table1', 't1');
$qry->addField('t1','etid','entity_id');
$qry->join('node', 'n FORCE INDEX(field1)', 'n.nid = t1.etid');
$qry->join('table2','t2','n.nid = t2.entity_id');
$qry->join('table3','t3','t3.sid=t2.field2');
$qry->condition('t3.field', 'yes', '=');
$qry->condition('n.field', '<value>', 'LIKE');
$qry->condition('t1.field', '<id>', '=');
$qry->condition('n.field', '<value>', '=');
$qry->condition('n.field', <value>, '=');
$qry->condition('t1.field', '<vlaue>', '=');
$qry->orderBy('t1.field','DESC');
$qry->range(0,300);

我想OR为这个查询添加一个条件。所以这将是一个全球性的OR条件。

我添加了如下代码

$or = db_or();
$or->condition('t1.field', [123,456], 'IN');
$qry->condition($or);

但它没有添加OR条件，而是将条件查询放在条件中的大括号内AND。

我怎样才能实现像这样的输出查询

where field = value and field = value and field = value OR field = value

通过使用 Drupal 查询生成器？请帮忙

使用db_and

$db_and = db_and();


$qry = db_select('table1', 't1');
$qry->addField('t1','etid','entity_id');
$qry->join('node', 'n FORCE INDEX(field1)', 'n.nid = t1.etid');
$qry->join('table2','t2','n.nid = t2.entity_id');
$qry->join('table3','t3','t3.sid=t2.field2');

$db_and->condition('t3.field', 'yes', '=');
$db_and->condition('n.field', '<value>', 'LIKE');
$db_and->condition('t1.field', '<id>', '=');
$db_and->condition('n.field', '<value>', '=');
$db_and->condition('n.field', <value>, '=');
$db_and->condition('t1.field', '<vlaue>', '=');

$or = db_or();
$or->condition('t1.field', [123,456], 'IN');
$or->condition($db_and);

$qry->condition($or);

$qry->orderBy('t1.field','DESC');
$qry->range(0,300);
