If you re migrating to ibm db2 universal database from a database that supports bit and boolean operations and functions, you may be wondering how to handle these types and functions in db2. our author offers a method that includes table creation with columns of the bit - like or boolean data types using constraints or triggers, and a set of user - defined functions to support bitwise and boolean operations that imitate bit or boolean data - type behavior
