FUNC_SHA1 Function
The FUNC_SHA1 function uses the SHA1 cryptographic hash function to convert a variable-length string into a 40-character string that is a text representation of the hexadecimal value of a 160-bit checksum.
Syntax
FUNC_SHA1(string)
Arguments
- string
-
A variable-length string.
Return Type
The FUNC_SHA1 function returns a 40-character string that is a text representation of the hexadecimal value of a 160-bit checksum.
Example
The following example returns the 160-bit value for the word 'Amazon Redshift':
