MD5_NUMBER — Deprecated

Snowflake logo in black (no text) Deprecated Feature

This function has been deprecated. It will be obsoleted in a future release (TBD).

In some cases, you can use MD5 , MD5_HEX or MD5_BINARY instead of this function.

Returns the 128-bit MD5 message digest interpreted as a signed 128-bit big endian number. This representation is useful for maximally efficient storage and comparison of MD5 digests.

Syntax

MD5_NUMBER(<msg>)

Arguments

msg

A string expression, the message to be hashed.

Returns

A signed integer (NUMERIC(38, 0)).

This integer can be outside the range stored by NUMERIC(38, 0), so this function has been deprecated.

Usage Notes

Although the MD5, MD5_BINARY, and MD5_NUMBER functions were originally developed as cryptographic functions, they are now obsolete for cryptography and should not be used for that purpose. They can be used for other purposes, for example as “checksum” functions to detect accidental data corruption.

Examples

SELECT md5_number('Snowflake');
