Storing UUID Values In MySQL Tables | MySQL Server Blog

A Version 4 UUID is a universally unique identifier that is generated using random numbers. The Version 4 UUIDs produced by this site were generated using a secure random number generator. The UUIDs generated by this site are provided AS IS without warranty of any kind, not even the warranty that the generated UUIDs are actually unique. Should I be concerned? Well, there are a couple of things here that are a little concerning. First: while it is true that a UNIQUEIDENTIFIER (i.e. Guid) is a byte binary value, it is also true that: All data can be stored in binary form (e.g. INT could be stored in BINARY(4), DATETIME can be stored in BINARY(8), etc), hence #2 ↴ There is probably a reason for having a separate datatype. Thanks for pointing that out. I saw that page as well and I plan to do all conversions outside of SQL Server. If I let it convert uniqueidentifier to binary(16) or vice versa, i will end up having the first 3 portions of the UUID byte-swapped. – oopoopoop Sep 9 '20 at Integer converter: Translate between 8, 16 and bit ints.

  A GUID or (UUID) is a universally unique identifier which is a bit number or (16 byte long). They are used for generating globally unique IDs that are guaranteed to be unique without using a central repository (like a database) to generate them. Typical uses are in various project files (dermatolog-kerch.ru dermatolog-kerch.ru). Read more at wikipedia. That is 16 possibilities for each digit.

So each hexadecimal digit represents 4 bits. There are 32 hex digits in a UUID times 4 bits gives a total of bits in a UUID. To determine the variant you look at the bits of the 17th hex digit in a UUID. For example, if the 4 binary digits begin "10" then the variant is "DCEISO/IEC ".

In the binary system, each binary digit refers to 1 bit. Decimal to binary conversion examples (51) 10 = () 2 () 10 = () 2 ()   And after playing a little more: declare @TestUI uniqueidentifier = '',@TestBin binary(16) = 0x6C7DCE8CA94FDC9D7CF2.

Some databases (PostgreSQL, SQL Server) offer a dedicated UUID storage type; Otherwise we can store the bits as a byte array (e.g. RAW(16) in Oracle or the standard BINARY(16) type) Alternatively we can use 2 bigint (bit) columns, but a composite identifier is less efficient than a single column one.

PHP: Uniqid - Manual

Please mind, that uuid() returns a UUID with dashes. We have to remove them with replace() in order to insert an entry. Moreover, we have to use unhex() which converts a hexadecimal (human-readable) UUID to its binary representation. Now it fits into a BINARY(16) column.

To convert Hexadecimal to Binary, we first convert the Hexadecimal to Decimal, then we use the same function as explained before to convert the decimal values to binary data. Hexadecimal conversion: Hexadecimal representation (litteraly base 16) is a very handfull notation for computers because it's more compact than decimal to store numbers. The binary numeral system, or base-2 number system, represents numeric values using two symbols, 0 and 1. More specifically, the usual base-2 system is a positional notation with a radix of 2. Owing to its straightforward implementation in digital electronic circuitry using logic gates, the binary system is used internally by all modern computers.
