Oracle STANDARD_HASH not available in PLSQL?
<p>I'm trying to use STANDARD_HASH Oracle (12c) function in PL/SQL but seems not available:</p>

<pre><code>SQL&gt; exec   dbms_output.put_line(STANDARD_HASH('test'));
BEGIN dbms_output.put_line(STANDARD_HASH('test')); END;

                           *
ERROR at line 1:
ORA-06550: line 1, column 28:
PLS-00201: identifier 'STANDARD_HASH' must be declared
ORA-06550: line 1, column 7:
PL/SQL: Statement ignored
</code></pre>

<p>From sql is working just fine:</p>

<pre><code>SQL&gt; select STANDARD_HASH('test') from dual;

STANDARD_HASH('TEST')
----------------------------------------
A94A8FE5CCB19BA61C4C0873D391E987982FBBD3
</code></pre>

<p>Why? What is the best way to implement the STANDARD_HASH in PLSQL?</p>

<p>Regards</p>
