+For more control over column quoting the ``Doctrine\ORM\Mapping\QuoteStrategy`` interface
+was introduced in 2.3. It is invoked for every column, table, alias and other
+SQL names. You can implement the QuoteStrategy and set it by calling

+The ANSI Quote Strategy was added, which assumes quoting is not necessary for any SQL name.
+You can use it with the following code:
+

+    use Doctrine\ORM\Mapping\AnsiQuoteStrategy;
