Hi,
Does throwing an exception in a windows service crash the service?
i.e. it will have to be restarted manually
Note: I am throwing the exception from within the catch clause.

What is the best way to check if a table exists in MySQL (preferably via PDO in PHP) without throwing an exception. I do not feel like parsing the results of "SHOW TABLES LIKE" et cetera. There must be some sort of boolean query?

SELECT COUNT(*) FROM information_schema.tables WHERE table_schema = '[database name]' AND table_name = '[table name]';
Any results indicate the table exists .
