I can't stand it, really.
I'm using it at the moment only because I'm forced to. I can't help considering it as a toy DB, especially comparing it to PostgreSQL or SQL Server or any other
serious RDBMS.
The last thing that hit my nerve is
this bug. Come on... can't it even handle foreign keys in a decent way?
And I'm trying not to think that it allows you to define a table with foreign keys and
silently ignore them.
