HASH_SHA512

Purpose

This function computes a hash value by using the SHA512 algorithm (512 Bit).

Syntax

hash_sha512::=

Usage Notes

  • Return values have data type CHAR(128) and contain hex characters.
  • The data types of the input parameters are significant. That is why HASH_SHA512(123) is different from HASH_SHA512('123').
  • Multiple input expressions are concatenated (in their internal byte representation) before the hash value is computed.

    • HASH_SHA512(c1,c2) is not similar to HASH_SHA512(c1||c2).

  • The function returns NULL if all input expressions are NULL.

Example

Copy 
SELECT HASH_SHA512('abc');
