This is a backport of the Drupal 7 PDO database compatibility layer for use with Drupal 6 modules.
It is named after the original issue by Larry "Crell" Garfield titled Database Layer: The Next Generation.
You should only install this module if another module instructs you to, as this module does not provide any end-user functionality.
This module does not override the existing database functionality but makes the new compatibility layer available under a series of functions identical to their Drupal 7 counterparts named dbtng_ instead of db_. For example with this module, use
dbtng_set_active instead of
db_set_active, with the exception of the following functions that funciton identically to their Drupal 7 conterparts:
Most code should be able to use the primary query building functions listed above without modification in both Drupal 6 and Drupal 7.
