Trying to install Drupal with SQL Azure backend and getting error below:
PDO is enabled:
If I comment out line 124 in database.inc the installation proceeds and I see some tables being created in MS SQL. However, it breaks at some point with:
Cannot convert '0' to int SQL Driver error
Which I assume is caused by not having setting above.
I would recommend you use the template Acquia Drupal 7 on SQL
from Azure Marketplace to create Drupal app with Azure SQL.
