SHA2

Calculates the SHA-2 family of hash functions (SHA-224, SHA-256, SHA-384, and SHA-512). If the hash length is not one of the permitted values, the return value is NULL. Otherwise, the function result is a hash value containing the desired number of bits as a string of hexadecimal digits.

Syntax

SHA2(<expr>, <expr>)

Examples

SELECT SHA2('1234567890', 0);
