XMLIsation into CLOB

Hi,
I have to convert a SQL into an XML, i am using DBMS_XMLQuery.newContext(Query in varchar2), and then use DBMS_XMLQyery.SetBINDVALUE to bind the variables. The process works for small queries, but does not work for queries having many columns. Is there a parameter which sets the length of query or the length of generated XML?
Thanks,

When you for example construct CLOBs programmatically from external sources (data stream is for example from UTL_FILE). The data in the CLOB could be loaded directly into a column - or it can be for example processed and parsed and values extracted to insert in standard varchar2/number/date columns.
XML processing for example. Often one also may need to construct CLOBs/LOBs that are temporary - never stored in the database. Typical example will be a stored proc that creates a temporary CLOB that contains XML that was build from a query, and then stream this CLOB to a web browser via MOD_PLSQL or EPG.
To be honest, I've almost never had to deal with a CLOB/LOB any other way than through DBMS_LOB's Write() and WriteAppend() methods.

How to read/write .CSV file into CLOB column in a table of Oracle 10g

I have a requirement which is nothing but a table has two column
create table emp_data (empid number, report clob)
Here REPORT column is CLOB data type which used to load the data from the .csv file.
The requirement here is
1) How to load data from .CSV file into CLOB column along with empid using DBMS_lob utility
2) How to read report columns which should return all the columns present in the .CSV file (dynamically because every csv file may have different number of columns) along with the primariy key empid).
eg: empid report_field1 report_field2
1 x y
Any help would be appreciated.

If I understand you right, you want each row in your table to contain an emp_id and the complete text of a multi-record .csv file.
It's not clear how you relate emp_id to the appropriate file to be read. Is the emp_id stored in the csv file?
To read the file, you can use functions from [UTL_FILE|http://download.oracle.com/docs/cd/B19306_01/appdev.102/b14258/u_file.htm#BABGGEDF] (as long as the file is in a directory accessible to the Oracle server):
declare
    lt_report_clob CLOB;
    l_max_line_length integer := 1024;   -- set as high as the longest line in your file
    l_infile UTL_FILE.file_type;
    l_buffer varchar2(1024);
    l_emp_id report_table.emp_id%type := 123; -- not clear where emp_id comes from
    l_filename varchar2(200) := 'my_file_name.csv';   -- get this from somewhere
begin
   -- open the file; we assume an Oracle directory has already been created
    l_infile := utl_file.fopen('CSV_DIRECTORY', l_filename, 'r', l_max_line_length);
    -- initialise the empty clob
    dbms_lob.createtemporary(lt_report_clob, TRUE, DBMS_LOB.session);
    loop
      begin
         utl_file.get_line(l_infile, l_buffer);
         dbms_lob.append(lt_report_clob, l_buffer);
      exception
         when no_data_found then
             exit;
      end;
    end loop;
    insert into report_table (emp_id, report)
    values (l_emp_id, lt_report_clob);
    -- free the temporary lob
    dbms_lob.freetemporary(lt_report_clob);
   -- close the file
   UTL_FILE.fclose(l_infile);
end;This simple line-by-line approach is easy to understand, and gives you an opportunity (if you want) to take each line in the file and transform it (for example, you could transform it into a nested table, or into XML). However it can be rather slow if there are many records in the csv file - the lob_append operation is not particularly efficient. I was able to improve the efficiency by caching the lines in a VARCHAR2 up to a maximum cache size, and only then appending to the LOB - see [three posts on my blog|http://preferisco.blogspot.com/search/label/lob].
There is at least one other possibility:
- you could use [DBMS_LOB.loadclobfromfile|http://download.oracle.com/docs/cd/B19306_01/appdev.102/b14258/d_lob.htm#i998978]. I've not tried this before myself, but I think the procedure is described [here in the 9i docs|http://download.oracle.com/docs/cd/B10501_01/appdev.920/a96591/adl12bfl.htm#879711]. This is likely to be faster than UTL_FILE (because it is all happening in the underlying DBMS_LOB package, possibly in a native way).
That's all for now. I haven't yet answered your question on how to report data back out of the CLOB. I would like to know how you associate employees with files; what happens if there is > 1 file per employee, etc.
HTH

You may have one of a few errors going for you there:
The error says your column in Oracle is a Long not a CLOB, if it is, then make your column a CLOB.
CLOB's are not suppored in all environments and/or all interfaces (specifically Windoz ODBC has a problem).
I believe a DOC (Windoz MS-Word) file is a BLOB, due to formatting characters in the file.
I had a very similar error using Access and trying to do this, but changing to SAS fixed the problem. It could very well be that your version of ODBC/JDBC drivers does not support it properly.

Insert into CLOB fails with Oracle ODBC driver version 9.02.00.65

I tried to insert into CLOB using the latest Oracle ODBC driver 9.02.00.65 and it fails. But the same works with earlier versions of ODBC driver earlier to 9.02.00.65 ie., 9.02.00.63.
Here is the code snippet I tried. Any help now is highly appreciated as I am in the crunch time.

Hi,
Since 9.2 has been desupported for error correction you will not be able to download that version from OTN. You should ask whoever is providing the training if their is an alternate version you can use. The only versions that you will be able to download from oracle.com is 10.2 11.1, and 11.2.

Hi
Ignore "SQL*Loader-292: ROWS parameter ignored when an XML, LOB or VARRAY column is loaded" error
after importing your csv file just change length CHAR(100000).

Error while loading data into clob data type.

Hi,
I have created interface to load data from oracle table into oracle table.In target table we have attribute with clob data type. while loading data into clob field ODI gave below error. I use odi 10.1.3.6.0

Select LONG column into CLOB variable

Hi all,
I am trying retrieve the data present in a LONG column into a CLOB variable.
However I am getting an error, pls let me know how I can resolve it.
DECLARE
v_text CLOB;
BEGIN
SELECT TO_LOB(trigger_body)
INTO v_text
FROM
user_triggers
WHERE
ROWNUM <= 1;
END;
ERROR at line 8:
ORA-06550: line 8, column 20:
PL/SQL: ORA-00932: inconsistent datatypes: expected NUMBER got LONG
ORA-06550: line 8, column 5:
PL/SQL: SQL Statement ignored
Let me know if there is an alternate to this. I would like to get the data present in the LONG column into a variable.
The reason why I am not retrieving the LONG column into LONG variable is stated below (from Oracle Website):
You can insert any LONG value into a LONG database column because the maximum width of a LONG column is 2**31 bytes.
However, you cannot retrieve a value longer than 32760 bytes from a LONG column into a LONG variable.
Thanks and Regards,
Somu

There are couple of things I did (listed in order):
1) Create Global Temporary Table containing a CLOB column
2) Select LONG column and convert to CLOB by using TO_LOB and insert into Global Temporary Table containing a CLOB column
2) Select from this Global Temporary Table (which already contains data in CLOB) and assign it to a CLOB variable.
This is done because you can not directly use TO_LOB in a select statement to assign the value to a CLOB variable.
Stated below is an example:
-- Create Temporary Table
CREATE GLOBAL TEMPORARY TABLE glb_tmp_table_lob(
time TIMESTAMP WITH LOCAL TIME ZONE,
text CLOB
ON COMMIT DELETE ROWS;
-- PL/SQL Block to Execute
DECLARE
v_clob CLOB;
BEGIN
-- Insert into Temporary Table by converting LONG into CLOB
INSERT INTO glb_tmp_table_lob (
time ,
text
SELECT
sysdate ,
TO_LOB(dv.text)
FROM
dba_views dv
WHERE
ROWNUM <= 1
-- Select from the Temporary table into the variable
SELECT
gt.text
INTO
v_clob
FROM
glb_tmp_table_lob gt;
COMMIT;
-- Now you can use the CLOB variable as per your needs.
END;

Post the 4 digit Oracle version.
Did you read the Doc for DBMS_LOB.CONVERTTOCLOB? - http://docs.oracle.com/cd/B28359_01/appdev.111/b28419/d_lob.htm
The function can convert data from one character set to another. If the source data uses a different character set than the target you need to provide the character set id of the source data.
The blob_csid parameter is where you would provide the value for the source character set.
If the source and target use the same character set then just pass zero. Your code is passing a one.
>
General Notes
You must specify the character set of the source data in the blob_csid parameter. You can pass a zero value for blob_csid. When you do so, the database assumes that the BLOB contains character data in the same character set as the destination CLOB.
>
Same for 'lang_context' - your code is using 1; just use 0. It is an IN OUT
>
lang_context
(IN) Language context, such as shift status, for the current conversion.
(OUT) The language context at the time when the current conversion is done.
This information is returned so you can use it for subsequent conversions without losing or misinterpreting any source data. For the very first conversion, or if do not care, use the default value of zero.

To load text into clob,long.

I am able to load data into clob,long.but it is not taking more than 4000 bytes.but i want to insert 10MB or more data.HOW?
It is giving error ORA-01704:

Cause: A quoted string specified as a constant was too long.
Action: Quoted strings may not contain more than 2000 characters.
what it means? and tell me How can I insert more text ie upto 1GB.
thanking you.......

null

does that
trace("Image Name=" +e.currentTarget.title)
trace what you want to display? if yes, add a textfield and assign its text property to e.currentTarget.title in your overScrollerItem listener function.

Can I store RTF file with image into CLOB?

I have created a WORD template document with company logo heading and format. I have to replace the 'user name', 'date' etc. data every time before I insert into my database. Therefore I store the template doc as RTF format.
1. Can I insert this doc (RTF with image) into CLOB or I have to store it in BLOB?
2. I want to store in CLOB because I sometimes have to change to content of the doc with replace statement. Actually, can I replace a string in BLOB too?

I understand RTF is a binary format and so needs to be stored as a BLOB.
The DBMS_LOB paackage contains procedures like INSTR() and WRITE() that may do what you what. Take them for a test drive.

Extract part of xml into CLOB or XMLType

I need to extract part of XML into CLOB or some another type. But I don't need only extract data, by whole part od xml with elements. How could I do it in PL/SQL?
For example from this xml:
<bookstore>
<book category="COOKING">
<title lang="en">Everyday Italian</title>
<author>Giada De Laurentiis</author>
<year>2005</year>
<price>30.00</price>
</book>
<book category="CHILDREN">
<title lang="en">Harry Potter</title>
<author>J K. Rowling</author>
<year>2005</year>
<price>29.99</price>
</book>
</bookstore>
I need to get:
"<book category="COOKING">
<title lang="en">Everyday Italian</title>
<author>Giada De Laurentiis</author>
<year>2005</year>
<price>30.00</price>
</book>"
THX

That's why I need to process every book alone - to know which authors belongs to single book.For that specific requirement, a single query would do.
Assuming variable "v_xml_clob" holds the XML document :
<bookstore>
<name>nameOfBookstore</name>
<address>1st Avenue 24, SF</address>
      <book category="COOKING">
        <title lang="en">Everyday Italian</title>
        <author>
          <name>Giada De Laurentiis</name>
          <birth>1956</birth>
        </author>
        <author>
          <name>xxx</name>
          <birth>1955</birth>
        </author>
        <year>2005</year>
        <price>30.00</price>
      </book>
      <book category="CHILDREN">
        <title lang="en">Harry Potter</title>
        <author>
          <name>Rowning</name>
          <birth>1977</birth>
        </author>
        <author>
          <name>xxx</name>
          <birth>1955</birth>
        </author>
        <year>2005</year>
        <price>29.99</price>
      </book>
</bookstore>You can do :
SELECT *
FROM XMLTable(
'for $i in distinct-values($d//book/author/name)
where count($d//book/author[name=$i]) = 1
return $i'
passing xmltype(v_xml_clob) as "d"
columns author_name varchar2(80) path '.'
AUTHOR_NAME
Rowning

XML into CLOB, corrupt text (Cyrillic charset, utf-8)

Hello, everyone!
We use Oracle ESB 10.1.3.5. We have problem with encoding/decoding(?) Cyrillic charset when putting xml-formatted data into CLOB. Here some details:
The FTP-adapter reads an XML-file (UTF-8) and transfers to RS-service. RS-service invokes the DB-adapter, which calls stored procedure in Oracle DB 10.2.0.4.(NLS_CHARACTERSET:CL8MSWIN1251) Procedure has one input parameter with type CLOB. Procedure does an insert into the table with a column of type CLOB. We wish to receive entire XML from initial file in a corresponding field of the table.
It works, except corrupted Cyrillic characters (mostly replaced with "?" symbols).
From ESB log we can see that db-adapter receive uncorrupted payload. We test to upload xml-file without ESB, using the same stored procedure, and the characters were introduced correctly.
Maybe someone faced with something like that, or have a thoughts, to solve this problem. Please help!

Hi,
I've got solution from support:
1)Add parameter -Dfile.encoding=UTF-8 in opmn.xml in the ESB container in JVM options:<process-type id="oc4j_soa" module-id="OC4J" status="enabled"> <module-data> <category id="start-parameters"> <data id="java-options" ... -Dfile.encoding=UTF-8"/> ...{quote}
2)opmnctl stopall;
3)opmnctl startall.
Thank You All.

Read text file into clob column

Dear Oracle users and Oracle support,
I have a text file that includes hundreds of data entries. The format is below. What I need to do is read each entry (
<DATALOAD ................</DATALOAD>) into the CLOB column as a table record. Then create a loop in the table to convert each record into XML data type. I have general idea on how to convert CLOB to XML. The difficult part to me is read the each entry in the text file to CLOB table. Please let me know what technique I should use. Any recommendation and sample code are welcome! I appreciate!
Thanks,
Bing
<DATALOAD ................</DATALOAD>
<DATALOAD ................</DATALOAD>
<DATALOAD ................</DATALOAD>
<DATALOAD ................</DATALOAD>

Hi,
Thank you for your response. What I want to achieve is read the text file into ClOB column. There are hundreds reocords in the text file. The format is below. Each entry is '<DATALOAD (sensitive data here, use....... instead)</DATALOAD>' that needs to be read into clob table as a record. That is basically what I need to achieve.
<DATALOAD ................</DATALOAD>
<DATALOAD ................</DATALOAD>
hundreds of them here........
<DATALOAD ................</DATALOAD>
<DATALOAD ................</DATALOAD>So, is it really a text file or is it a well structured XML file?
Just reading it into a CLOB to process is not likely to be the best way.
If each line of the file is a record, then you're likely to be better using something like External Tables.
If it's a structured XML file, then it can be read using CLOB functionality into an XMLTYPE datatype and then shredded down into relational table structures.
Be more clear in what your requirements are and we can help you better.

XML data 32K into CLOB

Hi all,
I am trying to use UTL_FILE.PUT_LINE to output an XML file. This xml file is the result of a select query. Hence converting the result of the select query into xml format using dbms_xmlgen.getxml and storing it in a variable. But the resultant xml data > 32k . What would be the best way to store it in variable? When using CLOB datatype, getting a numeric value error.
Thanks in advance.

As you didn't post the code, nor included a four digit database version, you are asking someone to look in a crystal ball.
Sorry, they are out for repair.
Also the XDB forum would be more appropriate.
