The MySQL function UUID_TO_BIN () is used to convert the valid string UUID of human-readable format to the binary UUID in a compact format. In contrast, BIN_TO_UUID () converts the binary UUID to the string UUID. The data type of the result generated by the UUID_TO_BIN () function is VARBINARY (16). The step by step process to convert from the decimal to the binary system is: Find the largest power of 2 that lies within the given number. Subtract that value from the given number. Find the largest power of 2 within the remainder found in step 2. Repeat until there is no remainder. BIN_TO_ UUID - From Binary to VARCHAR.You can use uuid4 () which generates a single random 128-bit integer UUID.
