because of the name, which suggests a kind of “nothing” that won’t do any harm if you add it to a number or stick it to the back of a string. In reality, performing such operations will render the entire generalised as follows for expressions with one type of binary boolean operator (and | or) and any number of operands: Disjunctions (“A or B or C or D or …”) 1. If at least one operand is true, the result section. 5.1. The IN predicate The IN predicate compares the expression on its left-hand side to a number of expressions passed in the argument list and returns true if a match is found. NOT IN always returns

Less resource use if the number of connections is low. A single process serves all connections, using threads to handle requests. Shared cache space. More efficient if the number of simultaneous connections Multiprocessor SMP (symmetrical multi-processor) sup- port. Better performance in case of a small number of connections that do not influ- ence each other. No SMP support. On multi-processor Win- dows Windows Classic Server launches a new process for every connection, so the number of fb_inet_server processes will always equal the number of client connections plus one.
