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:
MYSQL UUID GENERATOR HOW TO
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.
MYSQL UUID GENERATOR OFFLINE
UUID values can be generated offline means we can generate it anywhere without exchanging information with the database server.UUID values do not provide information about our data, which means it is hard to guess.

The following are the advantages of using UUID for a primary key: The following are advantages of UUID over AUTO_INCREMENT PRIMARY KEY: Advantages UUIDs in MySQL are a good alternative to AUTO_INCREMENT PRIMARY KEY. After successful execution of the above statement, it will generate the UUID value as follows: MySQL UUID vs. The above function returns a UUID value in agreement with UUID version 1 described in RFC 4122.
