Is there a way to invoke DBMS_CRYPTO directly from SQL?

Question

When I try to do this:-
INSERT INTO MyTable ( MyName ) VALUES
DBMS_CRYPTO.ENCRYPT(UTL_I18N.STRING_TO_RAW ('Graeme', 'AL32UTF8'),
DBMS_CRYPTO.ENCRYPT_AES128 + DBMS_CRYPTO.CHAIN_CBC + DBMS_CRYPTO.PAD_PKCS5,
UTL_I18N.STRING_TO_RAW('0123456789ABCDEF', 'AL32UTF8')
I get
ORA-06553: PLS-221: 'ENCRYPT_AES128' is not a procedure or is undefined.
However if I create a PL/SQL function MyEncrypt to do the same thing
INSERT INTO MyTable Name VALUES ( MyEncrypt('Graeme') );
it works fine. Hmm.
Is there a way to invoke the DBMS_CRYPTO package's functions directly from SQL?

Answer 1

You cannot reference packaged constants from pure SQL. You could replace the argument
DBMS_CRYPTO.ENCRYPT_AES128 + DBMS_CRYPTO.CHAIN_CBC + DBMS_CRYPTO.PAD_PKCS5,with the equivalent constants, i.e.
6 + 256 + 4096Of course, that isn't likely to be nearly as readable and/or maintainable as the first approach.
