SQL & PL/SQL :: ORA-22835 Buffer Too Small For CLOB To CHAR Or BLOB To RAW Conversion?
Sep 24, 2008
Recently I came across this issue, which gives me an error as following.
ERROR:
ORA-22835: Buffer too small for CLOB to CHAR or BLOB to RAW conversion (actual: 4907, maximum: 4000)
Now I am running a very simple query against one of the View in our Database.
Query is:
Select Prj_Num,
PM_Comments
From ProjectDetails
Where Rel = ‘2008 10’
What I have discovered so far is one of the field in this view name “PM_Comments” has more than 4000 bytes of information in it, Which is not supported by tools I have available on my computer. I have Oracle SQL Plus, SQL plus Worksheet, Access and Excel installed on my machine. DBA related to this database are stating that the field is working fine and query is executing without error since they are using TOAD for SQL, which does have capabilities to read more than 4000 bytes.
What I have figured out so far is “PM_Comments” is a LOB and SQL plus is having trouble reading this information more than 4000 bytes in one field of information.Because of this diagnosis, I have tried using following queries but it did not useful either.
Select Prj_Num,
Substr (PM_Comments, 1, 4000)
From ProjectDetails
Where Rel = ‘2008 10’
Select Prj_Num,
DBMS_LOB.Substr(PM_Comments, 4000, 1)
From ProjectDetails
Where Rel = ‘2008 10’
But both of the above mentioned queries did not work either. and I get the same ORA-22835 Error.I do not need all of the information in “PM_Comments” field, I only need about first 1000 characters of it.
I would need to convert the column datatype from BLOB to CLOB. currently in the table, the BLOB column has the data. the requirement is to convert this column from BLOB to CLOB datatype.
How to convert from BLOB datatype to CLOB datatype ?
I'm trying to create a table with a select statement. I want to populate this new table with the aggregated value from a VIEW. Following is the code used for creating the VIEW,
create or replace view FINAL_WEB_LOG as select SESSION_ID, SESSION_DT, C_IP, CS_USER_AGENT, tab_to_string(CAST(COLLECT(web_link) AS t_varchar2_tab)) WEBLINKS from web_views_tab group by C_IP, CS_USER_AGENT, SESSION_DT;
I want to create a table with WEBLINKS and SESSION_ID which is a sequence from another table.
CREATE TABLE FINAL_WEB AS SELECT weblinks FROM final_web_log UNION SELECT session_id FROM WEB_VIEWS_TAB;
This now gives me the following error,
SQL Error: ORA-06502: PL/SQL: numeric or value error: character string buffer too small
This has to do with the field, Weblinks, it does have longer values.
I have researched this problem and checked my variable sizes over and over again. I have tested the procedure within the Oracle Express environment and it works fine; HOWEVER, when the procedure is called from my C# app it produces the ORA-06502 error.
The stored procedure signature looks like this...
Original - SQL Code
create or replace save_new_project (p_custorgid in number, p_title in varchar2, p_AOIName in varchar2, p_description in varchar2, p_receiveddate in date, p_deadlinedate in date, p_startdate in date,
[code]....
The OracleParameter in my C# app for the last out param is defined as such...
As I said at the beginning of this post, the procedure works fine in the Oracle environment. So why is it not working by simply calling it from C#? I've tried changing the OracleDbType to CLOB which eliminates the error but it returns a bizarre result. It returns this string, "Oracle.DataAccess.Types.OracleClob".
Since CLOB doesn't really work either I switch back to Varchar2 and specify a size of 5000 (in the database the field I am querying is defined as Varchar(30)). I still get the ORA-06502 error.
I am clueless as to what the problem is. It should work and it does if I run a series of SQL statements in an Oracle SQL Command window. The test that works fine looks like this...
Original - SQL Code
declare v_projid projects.projectid%type; v_statustypedescrip projectstatustypes.type%type; /* this is a varchar(30) */ begin save_new_project(2, 'Some input text goes here', 'More input text', 'And more again','26-APR-2007','26-APR-2007','26-APR-2007','26-APR-2007','users name as inpujt text
[code]....
But calling save_new_project from C# throws ORA-06502. It identifies line 40 of my stored procedure. This is line 40...
when I want to create a table.When I run my procedure I received : PL/SQL: numeric or value error: character string buffer too small
create or replace PROCEDURE p_create_tmp_tables (p_result OUT NUMBER ) IS string_sql varchar2(1000); result NUMBER; BEGIN string_sql := 'CREATE TABLE TMP_CATEGORIES (CODE_CATEGORY NUMBER(6,0), NAME_CATEGORY VARCHAR2(25 BYTE))'; execute immediate string_sql; [code]...
I want to pass a damn long query(which includes a lot of column names, tables, joins, union, where clauses etc. and whose length is more than 120000) in a Ref cursor (that's length is more than 32767). Query is stored in a LONG type variable V_QRY in stored procedure, and I am opening that ref cursor like below-
OPEN P_RPT_TEST FOR V_QRY;
at run time its giveing string buffer too small error.
begin -- Initialize owa with an empty array, just so we can use htp. owa.init_cgi_env( param_val=>owa.cgi_var_name ); -- Add a header to avoid dealing with header-related code in htp. htp.prn('Content-Type:text/plain'); htp.print('');

The error I am getting is
ERROR at line 1: ORA-06502: PL/SQL: numeric or value error: character string buffer too small ORA-06512: at "SYS.HTP", line 1550 ORA-06512: at line 32
what i feel is that oracle Database UTF8 or AL32UTF8 characterset does not support htp package properly. When i run the code on another characterset, it runs errorfree except in UTF8 or AL32UTF8.
Actually I am getting the following error while running my script.

Actually I have an existing table in LOG RAW instead of BLOB. Which stores some transaction XML data. The data is very huge. When i trying with the following, gives me following error

Since dbms_output.put_line has buffer limitation.Can we write the result of a select statement into client LOCAL disk files using PL/SQL.
I am getting an error as below ORA-06502: PL/SQL: numeric or value error: character string buffer too small.
Here is complete code

i write a select statement in proc that contains 44 columns.
when i precompile it. it is showing the error: implicit conversion of string literal to "char *" is deprecated.when i compile the same select with 40 columns it is not showing any error.
but for more than 40 columns (41-44) it is showing the above error.

I having issue when i try to use CLOB as varchar2 is not enough in my case. I'm developing function column in oracle report. I'm using developer 6i. I get error function return must char?
How I can use CLOB in oracle report?

I have a table containing records with a field representing a png image that is encoded as base64 text. The procedure responsible for creating the record receives the base64 information in a parameter of type CLOB. It then inserts it in a field of same type on the record. I want to transform the CLOB data into an image and display it back on the form.
We have a huge table in production, with LONG column. We are trying to change its datatype to CLOB. The table has 120 Million records and is of 270 GB in size.
We tried using the oracle expdp/impdp option to try the conversion in our perf environment. With 32 parallels, the export completed in 1.5 hrs. However, the import took 13 hrs.
I also tried the to_lob option using inserts, it went on for 20 hrs and I killed the process. Are there any ways to improve the performance of LONG to CLOB conversion on huge tables?
I want to pass english character as a parameter and search a string that having swedish character, this needs to be done for all the swedish characters.
test _t table having the below 3 values

2. If user searches based on swedish char like below then they should get only 2 values bcz fist & last have swedish ä and second one having english a.
select name from test_t where name like '%ä%'

Is any in-built function available, for Text alternative string search. If not how to search the string based on the query.
Does cache buffer chain latch and buffer busy wait event are related to one any another.
Latch definition from Google says : Latches are simple, low-level serialization mechanisms to protect shared data structures in the system global area (SGA).
what does it mean my protect. Does this mean protects from aging as per LRU algorithm and getting removed from SGA or protect from other processes ,say from example from simultaneously DML operations. or both
Does buffer busy wait event occurs , because of the cache buffer chain latch ?
