Element name too long when using ROWTYPE

Question

I've come across an issue with xml element names longer than 30 characters. Seems it has something to do with ROWTYPE. Creation of this function is successful:
<pre>
CREATE OR REPLACE FUNCTION test_fnc
RETURN XMLTYPE
AS
var_return XMLTYPE;
l_dummy DUAL.dummy%TYPE;
BEGIN
SELECT dummy INTO l_dummy FROM DUAL;
SELECT XMLCONCAT(XMLELEMENT (
"TEST",
XMLFOREST (
l_dummy "THIS_IS_OVER_30_CHARACTERS_LONG"
data_set
INTO var_return
FROM DUAL;
RETURN var_return;
END test_fnc;
</pre>
However, specifying the variable as ROWTYPE gives ORA-00972 error (unless I shorten the element name...):
<pre>
CREATE OR REPLACE FUNCTION test_fnc
RETURN XMLTYPE
AS
var_return XMLTYPE;
l_dummy DUAL%ROWTYPE;
BEGIN
SELECT dummy INTO l_dummy FROM DUAL;
SELECT XMLCONCAT(XMLELEMENT (
"TEST",
XMLFOREST (
l_dummy.dummy "THIS_IS_OVER_30_CHARACTERS_LONG"
data_set
INTO var_return
FROM DUAL;
RETURN var_return;
END test_fnc;
</pre>
Has anyone come across this before, or have any ideas for a solution? I could specify all my variables as TYPE but as there are many within the tables it would be easier to use ROWTYPE.

Answer 1

it works if you add "AS" after l_dummy.dummy
SQL> CREATE OR REPLACE FUNCTION test_fnc
  2     RETURN XMLTYPE
  3  AS
  4     var_return   XMLTYPE;
  5     l_dummy      DUAL%ROWTYPE;
  6  BEGIN
  7     SELECT   dummy INTO l_dummy FROM DUAL;
  8
  9     SELECT   XMLCONCAT(XMLELEMENT (
10                           "TEST",
11                           XMLFOREST (
12                              l_dummy.dummy AS "THIS_IS_OVER_30_CHARACTERS_LONG"
13                           )
14                        ))
15                 data_set
16       INTO   var_return
17       FROM   DUAL;
18  RETURN var_return;
19  END test_fnc;
20  /
