...while, and another thread stops your thread in the worst possible way ( it calls thread.stop() ). Your catch block will catch a ThreadDeath Error. This is super bad. The behavior of your code after catching that Exception is largely undefined.
A similar problem occurs with catching Exception. M...
What are good alternatives to SQL (the language)? [closed]
...QL's syntax is difficult to work with, both from the standpoint of automatically generating it, and from the standpoint of parsing it, and it's not the style of language we would write today if we were designing SQL for the demands we place on it today. I don't think we'd find so many varied keyword...
Create PostgreSQL ROLE (user) if it doesn't exist
...issuing CREATE ROLE unconditionally and then catching exceptions from that call. There is just one problem with these solutions. They silently drop any errors, including those which are not generated by fact that role already exists. CREATE ROLE can throw also other errors and simulation IF NOT EXIS...

LINQ-to-SQL vs stored procedures? [closed]
... support. It would be MUCH harder to do this data access code that simply calls sprocs.
Debugging support: I can use any .NET debugger to debug the queries. With sprocs, you cannot easily debug the SQL and that experience is largely tied to your database vendor (MS SQL Server provides a query anal...
