Fetch statement issue

Question

declare
c1               r_cursor;
l_PIP_xml_data_clob     long;
l_xml_query          long;
begin
l_xml_query:='Dynamically constructed sql query';
open c1 for l_xml_query;
loop
     fetch c1 into l_PIP_xml_data_clob;
     exit when c1%notfound;
     l_PIP_xml_data_xmltype := xmltype(l_PIP_xml_data_clob);
end loop;
In the above example at the fetch statement i am getting the following error
ERROR at line 1:
ORA-19011: Character string buffer too small
ORA-06512: at "INTFMGR.EBIZ_RN", line 1250
ORA-06512: at line 6
Here i have used long data type which is enough to hold the resultant data.But it is showing "Character string buffer too small".
Any idea pls.
cheers

Answer 1

Use it for l_PIP_xml_data_clob then, since that's the variable holding the return value. Which is pretty evident from the name that it probably should be a clob datatype anyway.
Sounds like the value you're returning is a clob that's over the limit of what a long can hold.
