The WHERE clause, if given, indicates the condition or conditions that the records must satisfy to be selected.
|
|
|
|
Doctrine_Query provides easy to use WHERE -part management methods where and addWhere. The where methods always overrides
|
|
the query WHERE -part whereas addWhere adds new condition to the WHERE -part stack.

|
<code type="php">
|
|
// find all groups where the group primary key is bigger than 10
|
|
|
|
\$coll = \$q->from('Group')->where('Group.id > 10');
|
|
|
|
// the same query using Doctrine_Expression component
|
|
\$e = \$q->expr;
|
|
\$coll = \$q->from('Group')->where(\$e->gt('Group.id', 10));
|

?></code>

Using regular expression operator:
|
|
|
|
|
|
<code type="php">
|
|
// find all users where users where user name matches
|
|
// a regular expression, regular expressions must be
|
|
// supported by the underlying database
|
|
|
|
\$coll = \$conn->query(\"FROM User WHERE User.name REGEXP '[ad]'\</code></code>
|
|
|
|
|
|
|
|
DQL has support for portable LIKE operator:
|
|
|
|
|
|
<code type="php">
|
|
// find all users and their associated emails
|
|
// where SOME of the users phonenumbers
|
|
// (the association between user and phonenumber
|
|
// tables is One-To-Many) starts with 123
|
|
|
|
\$coll = \$q->select('u.*, e.*')
|
|
->from('User u LEFT JOIN u.Email e LEFT JOIN u.Phonenumber p')
|
|
->where(\"p.phonenumber LIKE '123%'\</code></code>
|
|
|
|
|
|
|
|
Using multiple conditions and condition nesting are also possible:
|
|
|
|
|
|
<code type="php">
|
|
// multiple conditions
|
|
|
|
\$coll = \$q->select('u.*')
|
|
->from('User u LEFT JOIN u.Email e')
|
|
->where(\"u.name LIKE '%Jack%' AND e.address LIKE '%@drinkmore.info'\");
|
|
|
|
// nesting conditions
|
|
|
|
\$coll = \$q->select('u.*')
|
|
->from('User u LEFT JOIN u.Email e')
|
|
->where(\"u.name LIKE '%Jack%' OR u.name LIKE '%John%') AND e.address LIKE '%@drinkmore.info'\</code></code>
