Albus Dumbledore- Dumbledore means bumblebee, which I suppose. would fit... Draco Malfoy- Draco meaning dragon or refering to a cruel Athenian lawmaker. The mal in Malfoy meaning evil or bad, and foy, more commonly know as foi in french, means faith, so Malfoy would mean Badfaith.
Transactions (Transact-SQL) A transaction is a single unit of work. If a transaction is successful, all of the data modifications made during the transaction are committed and become a permanent part of the database. If a transaction encounters errors and must be canceled or rolled back, then all of the data modifications are erased.
Correlated subquery. In a SQL database query, a correlated subquery (also known as a synchronized subquery) is a subquery (a query nested inside another query) that uses values from the outer query. Because the subquery may be evaluated once for each row processed by the outer query, it can be inefficient.
