BASE64ENCODE scalar function

The BASE64ENCODE function returns the Base64 encoded version of the binary values of a character string.

The schema is SYSTOOLS.

character-string: A character expression to be encoded. The maximum length in 2732 characters.

The result of the function is a varying length character string in CCSID 1208 that contains the bytes of character-string as a Base64-encoded string.

Example

Encode a string that contains the value X'1122334455'.
```
VALUES SYSTOOLS.BASE64ENCODE(X'1122334455');
```
The result is: ESIzRFU=.
Encode a character string in CCSID 37 that contains the value 'ABC'.
```
VALUES SYSTOOLS.BASE64ENCODE('ABC');
```
The result is: wcLD
Encode a UTF-8 string that contains the value 'ABC'.
```
VALUES SYSTOOLS.BASE64ENCODE(CAST('ABC' AS VARCHAR(10) CCSID 1208));
```
The result is: QUJD
