Feature: #79262 - Add possibility to create TRIM expression with Doctrine DBAL
|
|
==============================================================================
|
|
|
|
See :issue:`79262`
|
|
|
|
Description
|
|
===========
|
|
|
|
The possibility to create TRIM expressions using Doctrine DBAL has been integrated.
|
|
However, when using this in comparisons, ExpressionBuilder::comparison() has to be
|
|
invoked explicitly - otherwise the created TRIM expression would be quoted if e.g.
|
|
used with ExpressionBuilder::eq().
|
|
|
|
.. code-block:: php
|
|
|
|
$queryBuilder->expr()->comparison(
|
|
$queryBuilder->expr()->trim($fieldName),
|
|
ExpressionBuilder::EQ,
|
|
$queryBuilder->createNamedParameter('', \PDO::PARAM_STR)
|
|
);
|
|
|
|
The call to :php:`$queryBuilder->expr()-trim()` can be one of the following:
|
|
|
|
* :php:`trim('fieldName')`
|
|
results in :sql:`TRIM("tableName"."fieldName")`
|
|
|
|
* :php:`trim('fieldName', AbstractPlatform::TRIM_LEADING, 'x')`
|
|
results in :sql:`TRIM(LEADING "x" FROM "tableName"."fieldName")`
|
|
|
|
* :php:`trim('fieldName', AbstractPlatform::TRIM_TRAILING, 'x')`
|
|
results in :sql:`TRIM(TRAILING "x" FROM "tableName"."fieldName")`
|
|
|
|
* :php:`trim('fieldName', AbstractPlatform::TRIM_BOTH, 'x')`
|
|
results in :sql:`TRIM(BOTH "x" FROM "tableName"."fieldName")`
