Hi Guys,
I was trying to use the hashing functions to convert strings into hashed values, I have tried MD5() and SHA1() and both two functions worked perfectly.
But when I tried to use SHA256(‘hi’), I got this error: Error: VALIDATION ERROR: No match found for function signature sha256()
I also tried sha2(‘hi’, 256), and got this error: Error: FUNCTION ERROR: SHA2 does not support operand types (VARCHAR,INTEGER)
Does anyone know how to get sha256 or sha2 functions work?
Thank you guys so much!
