+string_expression [NOT] LIKE pattern_value [ESCAPE escape_character] +
+ +
+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 single-character 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: +
+ +
+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. diff --git a/manual/docs/DQL (Doctrine Query Language) - Conditional expressions - Null Comparison Expressions.php b/manual/docs/DQL (Doctrine Query Language) - Conditional expressions - Null Comparison Expressions.php new file mode 100644 index 000000000..e69de29bb diff --git a/manual/docs/DQL (Doctrine Query Language) - Conditional expressions - Operators and operator precedence.php b/manual/docs/DQL (Doctrine Query Language) - Conditional expressions - Operators and operator precedence.php new file mode 100644 index 000000000..ec193d0ba --- /dev/null +++ b/manual/docs/DQL (Doctrine Query Language) - Conditional expressions - Operators and operator precedence.php @@ -0,0 +1,14 @@ +The operators are listed below in order of decreasing precedence. + diff --git a/manual/docs/DQL (Doctrine Query Language) - Conditional expressions - Path expressions.php b/manual/docs/DQL (Doctrine Query Language) - Conditional expressions - Path expressions.php new file mode 100644 index 000000000..e69de29bb diff --git a/manual/docs/DQL (Doctrine Query Language) - FROM clause.php b/manual/docs/DQL (Doctrine Query Language) - FROM clause.php new file mode 100644 index 000000000..53c91ef2d --- /dev/null +++ b/manual/docs/DQL (Doctrine Query Language) - FROM clause.php @@ -0,0 +1,31 @@ +Syntax:

+
+ +The FROM clause indicates the component or components from which to retrieve records. +If you name more than one component, you are performing a join. +For each table specified, you can optionally specify an alias. +

+ + +
  • The default join type is LEFT JOIN. This join can be indicated by the use of either 'LEFT JOIN' clause or simply ',', hence the following queries are equal: +
    +
    +SELECT u.*, p.* FROM User u LEFT JOIN u.Phonenumber
+
+SELECT u.*, p.* FROM User u, u.Phonenumber p
+
    +
    + +
  • INNER JOIN produces a Cartesian product between two specified components (that is, each and every record in the first component is joined to each and every record in the second component). +So basically INNER JOIN can be used when you want to efficiently fetch for example all users which have one or more phonenumbers. +
    +
    +SELECT u.*, p.* FROM User u INNER JOIN u.Phonenumber p
