The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

UTL_RAW/ RETRIEVE LONGRAW DATA

Asked by kaveena in Oracle Database

Hi All
There is a table in Oracle 9i Releaase 2
with a LONGRAW column
SQL> DESC NARRATIVE
Name Null? Type
------------------------------- -------- ----
NARRATIVE_ID NOT NULL NUMBER(15)
PARENT_TABLE_ID NOT NULL NUMBER(15)
NARRATIVE_TYPE NOT NULL VARCHAR2(1)
NARRATIVE LONG RAW

I need to read the data in the LONGRAW column. I tried using the
UTL_RAW.CAST_TO_VARCHAR2 package and tried to dump the LONG
RAW data to a LONG COLUMN.

declare
l_text long;
l_raw long raw;
l_text_length number;
begin
for x in ( select rowid r, t.* from narrative t )
loop
l_text := utl_raw.cast_to_varchar2(x.narrative);
l_text_length := length(l_text);
dbms_output.put_line( 'it is ' || length(l_text) || ' bytes
longs');
insert into narrative_long_tbl values (x.narrative_id, x.parent_table_id,
x.narrative_type, l_text);
commit;
end loop;
end;

When i execute this in SQL*PLUS this is the result
SQL> @retrieve_test_raw.sql
21 /
it is 23040 bytes
longs
it is 29184 bytes
longs
declare
*
ERROR at line 1:
ORA-06502: PL/SQL: numeric or value error
ORA-06512: at line 6

Is this error because the data is > 32000 bytes? The data stored in
NARRATIVE
column is actually a word document per row.

How can i retrieve LONG RAW data? Please help.

Thanks,
Kaveena.
