mysql uuid_short()

MySQL的uuid_short()函数是在MySQL 5.1之后的版本提供的一个函数，用于生成一个64位的无符号整数。这个函数的返回值的构造方式是通过(server_id & 255) << 56 + (server_startup_time_in_seconds << 24) + incremented_variable来生成的。 与uuid()函数相比，uuid_short()函数生成的值相对较短，适用于需要较短唯一标识的情况。在MySQL中，可以通过自增序列、UUID()函数、和程序自定义的方式实现唯一值。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
