Like Expressions
Syntax:
string_expression [NOT] LIKE pattern_value [ESCAPE escape_character]
Listing
9-83
The string_expression must have a string value. The pattern_value is a string literal or a
string-valued input parameter in which an underscore (_) stands for any single character, a
percent (%) character stands for any sequence of characters (including the empty sequence),
and all other characters stand for themselves. The optional escape_character is a singlecharacter
string literal or a character-valued input parameter (i.e., char or Character) and is
used to escape the special meaning of the underscore and percent characters in
pattern_value.
Examples:
• address.phone LIKE '12%3' is true for '123' '12993' and false for '1234'
• asentence.word LIKE 'l_se' is true for 'lose' and false for 'loose'
• aword.underscored LIKE '\_%' ESCAPE '\' is true for '_foo' and false for 'bar'
• address.phone NOT LIKE '12%3' is false for '123' and '12993' and true for '1234'
If the value of the string_expression or pattern_value is NULL or unknown, the value of the
LIKE expression is unknown. If the escape_characteris specified and is NULL, the value of the
LIKE expression is unknown.
Find all users whose email ends with '@gmail.com':
// test.php
Listing
9-84
// ...
$q = Doctrine_Query::create()
->select('u.id')
->from('User u')
->leftJoin('u.Email e')
->where('e.address LIKE ?', '%@gmail.com');
echo $q->getSqlQuery();
The above call to getSql() would output the following SQL query:
SELECT
u.id AS u__id
FROM user u
LEFT JOIN email e ON u.id = e.user_id
WHERE e.address LIKE ?

Find all users whose name starts with letter 'A':
// test.php
Listing

// ...
$q = Doctrine_Query::create()
->select('u.id')
->from('User u')
