How can I declare a Boolean parameter in SQL statement?

Question

How can I declare a Boolean parameter in SQL statement? Answer The same way you declare any other variable, just use the bit type: Note this is semantically different from a true boolean. The 1/0 values won't always just map to true/false the way you might expect.
