[TYPO3-core] RFC #10786: Add a wrapper for mysql_fetch_field in t3lib_db

[Christopher Hlubek]

Hi,

this is a SVN patch request.

Type: Feature

BT Reference: http://bugs.typo3.org/view.php?id=10786

Branch: trunk

Problem:
The Extbase persistence needs a new database method to fetch extended 
field information for a query result with joined tables (e.g. for eager 
loading of "has one" relations). This can be done with mysql_fetch_field 
but it is not available as a wrapper function in t3lib_db right now.

Solution:
Add a sql_fetch_field wrapper function to t3lib_db.

Greetings,

Christopher
