DQL Functions

This library provide set of cross database doctrine DQL functions. Supported databases are MySQL and PostgreSQL. Available functions:

  • DATE(expr) - Extract the date part of a date or datetime expression
  • TIME(expr) - Extract the time portion of the expression passed
  • TIMESTAMP(expr) - Convert expression to TIMESTAMP
  • TIMESTAMPDIFF(unit, datetime_expr1, datetime_expr2) - Returns datetime_expr2 – datetime_expr1, where datetime_expr1 and datetime_expr2 are date or datetime expressions. The unit should be one of the following values: MICROSECOND (microseconds), SECOND, MINUTE, HOUR, DAY, WEEK, MONTH, QUARTER, or YEAR.
  • CONVERT_TZ(expr, from_tz, to_tz) - Converts a datetime value expr from the time zone given by from_tz to the time zone given by to_tz and returns the resulting datetime value
  • DAY(expr) - Return the day of the month (0-31)
  • DAYOFWEEK(expr) - Returns the weekday index for date (1 = Sunday, 2 = Monday, …, 7 = Saturday). These index values correspond to the ODBC standard.
  • DAYOFMONTH(expr) - Returns the day of the month for date, in the range 1 to 31, or 0 for dates such as '0000-00-00' or '2008-00-00' that have a zero day part.
  • DAYOFYEAR(expr) - Return the day of the year (1-366)
  • HOUR(expr) - Return the hour from the date passed
  • MD5(expr) - Calculate MD5 checksum
  • MINUTE(expr) - Return the minute from the date passed
  • MONTH(expr) - Return the month from the date passed
  • QUARTER(expr) - Return the quarter from the date passed
  • SECOND(expr) - Return the second from the date passed
  • WEEK(expr) - The number of the week of the year that the day is in. By definition (ISO 8601), weeks start on Mondays and the first week of a year contains January 4 of that year. In other words, the first Thursday of a year is in week 1 of that year.
  • YEAR(expr) - Return the year from the date passed
  • POW(expr, power) - Return the argument raised to the specified power
  • ROUND(value, precision) - Return the value formated with the precision specified
  • SIGN(expr) - Return the sign of the argument
  • CAST(expr as type) - Takes an expression of any type and produces a result value of a specified type. Supported types are: "char, string, text, date, datetime, time, int, integer, decimal, boolean"
  • CONCAT_WS - Concatenate all but the first argument with separators. The first argument is used as the separator string.
  • GROUP_CONCAT - Return a concatenated string
  • REPLACE(subject,from,to) - Replaces all occurrances of a string "from" with "to" within a string "subject"
  • DATE_FORMAT(date,format) - Formats the date value according to the format string. The following specifiers may be used in the format string. The % character is required before format specifier characters.

GROUP_CONCAT full syntax:

GROUP_CONCAT([DISTINCT] expr [,expr ...]
            [ORDER BY {unsigned_integer | col_name | expr}
                [ASC | DESC] [,col_name ...]]
            [SEPARATOR str_val])

Installation

Add the following dependency to your composer.json

{
    "require": {
        "oro/doctrine-extensions": "dev-master"
    }
}

Functions Registration

Doctrine2

Doctrine2 Documentation: "DQL User Defined Functions"

<?php
$config = new \Doctrine\ORM\Configuration();
$config->addCustomStringFunction('group_concat', 'Oro\ORM\Query\AST\Functions\String\GroupConcat');
$config->addCustomNumericFunction('hour', 'Oro\ORM\Query\AST\Functions\SimpleFunction');
$config->addCustomDatetimeFunction('date', 'Oro\ORM\Query\AST\Functions\SimpleFunction');

$em = EntityManager::create($dbParams, $config);

Symfony2

In Symfony2 you can register functions in config.yml

doctrine:
    orm:
        dql:
            datetime_functions:
                date:           Oro\ORM\Query\AST\Functions\SimpleFunction

Silex

If you are using an ORM service provider make sure that you are adding the custom function to the configuration

for palmasev/DoctrineORMServiceProvider

    $config = $app['doctrine_orm.configuration'];

    $config->addCustomDateTimeFunction( 'year', 'Oro\ORM\Query\AST\Functions\SimpleFunction' );
    $config->addCustomDateTimeFunction( 'month', 'Oro\ORM\Query\AST\Functions\SimpleFunction' );

                    'date_format'   => 'Oro\ORM\Query\AST\Functions\String\DateFormat'
                ]
            ]
        ]
    ]
];

Extendability and Database Support

Architecture

Most of functions, that require only one ArithmeticPrimary argument may be parsed with Oro\ORM\Query\AST\Functions\SimpleFunction. This class is responsible for parsing function definition and saving parsed data to parameters. It is extended from Oro\ORM\Query\AST\Functions\AbstractPlatformAwareFunctionNode. This layer work with DQL function parsing. SQL generation is responsibility of platform specific functions, that extends PlatformFunctionNode. AbstractPlatformAwareFunctionNode creates appropriate instance of platform function based on current connection Database Platform instance name and DQL function name.

Platform function classes naming rule is:

Oro\ORM\Query\AST\Platform\Functions\$platformName\$functionName

Adding new platform

To add support of new platform you just need to create new folder Oro\ORM\Query\AST\Platform\Functions\$platformName and implement required function there according to naming rules

Adding new function

In case when your function is function with only one ArithmeticPrimary argument you may not create DQL function parser and use Oro\ORM\Query\AST\Functions\SimpleFunction for this. Then only platform specific SQL implementation of your function is required.

In case when your are implementing more complex function, like GROUP_CONCAT both DQL parser and SQL implementations are required.

If you want to add new function to this library feel free to fork it and create pull request with your implementation. Please, remember to update documentation with your new functions. All new functions MUST be implemented for all platforms.

Field Types

This library also consist additional field types:

  • MoneyType
  • PercentType
  • ObjectType
  • ArrayType

ObjectType and ArrayType use base64 encoded string to store values in Db instead of storing serialized strings. For backward compatibility values that are already stored in Db will be unserialized without base64 encoding. New values will be base64 encoded before storing in Db and base64 decoded before unserialization.
