What is SQL Bitmask?

Bitmasking is an exercise of compiling multiple values that are normally represented in a number of data types to a single computer word. In a previous example, we used the binary data type to see how bit manipulation is represented visually.

How do I create a bitmask?

Explanation: A signed integer with a value of -1 is represented in binary as all ones. Shift left the given number of times to add that many 0’s to the right side. This will result in a ‘reverse mask’ of sorts. Then negate the shifted result to create your mask.
