Re: Why the index is not used ?

I haven’t looked up what pgp_sym_encrypt() does but assuming it does encryption the way you should be for credit card data then it will be using a random salt and the same input value won’t encrypt to the same output value so

====

WHERE cc=pgp_sym_encrypt('test value 32', 'motdepasse');

wouldn’t work because the value generated by the function when you are searching on isn’t the same value as when you stored it.
