[TYPO3-core] RFC #11047: DBAL does not support CLOB/BLOB when using a mapped table name

[Xavier Perseguers]

Hi,

This is a SVN patch request.

Type: Bugfix

Branches: trunk (other branches might apply too)

BT reference: http://bugs.typo3.org/view.php?id=11047

Problem:
When dealing with CLOB/BLOB fields, special care should be taken in 
INSERT and UPDATE statements. However DBAL does not handle it carefully 
when the query contains a mapped table name, e.g., when using this 
configuration:

$TYPO3_CONF_VARS['EXTCONF']['dbal']['mapping'] = array(
     'tx_templavoila_datastructure' => array(
         'mapTableName' => 'tx_templavoila_ds',
     ),
);

In this case, the query contains table 'tx_templavoila_ds' instead of 
'tx_templavoila_datastructure' and DBAL is not able anymore to detect 
that a column is of type BLOB/CBLOB leading to an invalid query being 
issued to the database.

Solution:
Make sure the original table name is used when retrieving a field's 
metatype.
