Summary: Hash Functions in BeamSQL
Key: BEAM-10074
URL: https://issues.apache.org/jira/browse/BEAM-10074
Project: Beam
Issue Type: New Feature
Components: dsl-sql
Reporter: Darshan Jani
Assignee: Darshan Jani
I would like to propose hash functions:
# MD5
Calculates an MD5 128-bit checksum of string or bytes and returns it as a hex
string
_Note:_ calcite has a function with String as input but not for bytes as input.
{code:java}
SELECT MD5("Some String") as md5;
{code}
# SHA1
Calculates a SHA-1 hash value of string and returns it as a hex string.
_Note:_ calcite has a function with String as input but not for bytes as input.
{code:java}
SELECT SHA1("Some String") as sha1;
{code}
# SHA256
Calculates a SHA-256 hash value of string and returns it as a hex string.
{code:java}
SELECT SHA256("Some String") as sha256;
{code}
# SHA512
Calculates a SHA-512 hash value of string and returns it as a hex string.
{code:java}
SELECT SHA512("Some String") as sha512;
{code}
