![]() ![]() It produces a value that conforms to a 16 byte version1 UUID. This function produces a Short Universal Unique Identifier as a 64-bit unsigned integer, which differs from the string-format 128-bit identifiers produced by the UUID() function. The basic differences between them are discussed in the below comparison chart: UUIDĪ UUID is a Universal Unique Identifier specified by RFC 4122 and 128-bit long value represented as UTF8 string of five hexadecimal numbers. UUID() and UUID(short) both are different functions in MySQL. We will get the output as follows: MySQL UUID vs UUID(short) Mysql> SELECT BIN_TO_UUID(emp_id) AS ID, name FROM employee First, we will create a new table named employee using the below statement: Let us understand how to use the UUID with the help of an example. If the argument is NULL, it will return NULL. It returns 1 when the argument is valid and returns 0 for an invalid argument. The IS_UUID() function is used to validate the string format of UUID. The BIN_TO_UUID() function is used to convert the UUID from the compact format to a human-readable format for displaying. The UUID_TO_BIN() function is used to convert the UUID values from a human-readable format into a compact format for storing it in the databases. ![]() NOTE: It is to note that these functions are only available in the MySQL version 8.0 or later. These functions allow us to store UUID values in a compact format (BINARY) and display them in a human-readable format (VARCHAR). We can overcome these issues in MySQL by using the functions given below.
