Changes for version 0.69
- ENHANCEMENTS:
- Add count method to Alzabo::DriverStatement objects.
- BUG FIXES:
- - A particularly nasty bug sometimes manifested itself when removing a foreign key. This bug caused the deletion of all foreign keys involving the _corresponding_ column(s) in the foreign table. Needless to say, this could make a big mess.
- A join that included a where clause with an 'OR' generated improper SQL. Reported by Ilya Martynov.
- Calling the Alzabo::Runtime::JoinCursor->next_as_hash method when the query involved an outer join could cause a runtime error.
- In where clause specifications, 'and' and 'or' were only being allowed in lower-case. They are now allowed in any case.
- Aliases did not work in outer joins. This has been fixed.
- Using outer joins was a bit fragile, in that the order of the outer join in the context of the other joins could cause Alzabo to generate incorrect SQL. Now outer joins should work no matter what.
- A couple links in the schema creator had a hardcoded ".mhtml" extension, as opposed to using the value of Alzabo::Config::mason_extension(). Patch by Scott Lanning.
