  • How hard is it to determine what procedures/functions no longer compile?

    - by Dave
    In sql server how difficult would it be to determine what procedures/functions no longer compile? In other words, if I scripted out alter statements for all procedures and functions in a database, I'd like to know which of these statements are going to fail? I've been working on cleaning up a database I've inherited which has gone through years of changes and I'd like to what objects are going to raise errors when something tries to execute it.

  • [ZF] How to use Zend_Db without SQL Queries?

    - by rasouza
    The last time I worked with Zend_Db I recall I used to write SQL Queries manually. I've been searching for some ORM application, but, since I read something like Zend_Db is also capable of doing so, I started to try it, but I can't find neither a good tutorial explain it or a good documentation. I read something lake Gateway pattern and ModelMapper class but I can't figure it out. Can someone shine my path? :P
