+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")`
