Select this OPTION to generate XML data from the table using XMLELEMENT, XMLAGG gives error ORA-19011 string buffer too small
My select statement fails with the error:
The ORA-19011 string buffer too small
The select statement looks like:
SELECT TO_CLOB)
XMLELEMENT ("accounts",
XMLELEMENT ("count",
XMLATTRIBUTES)
rownum AS "recordId."
To_date('20130520','YYYYMMDD') AS "datestarted."
123456 AS "previousBatchId."
56789 AS 'previousRecordId '.
),
....
.... .
.....
XMLFOREST)
SIG_ROLE AS "SignatoryRole."
To_char(TRANSFER_DATE,'YYYY-mm-DD') AS "TransferDate."
NVL(Reason,0) AS 'reason '.
) AS the 'transfer '.
)
()) AS CRDTRPT
OF ANY_TABLE;
- It looks like I can choose only 4000 characters using the SELECT statement (please, correct me if I'm wrong)
I'd use the XMLGEN package. But the environment team says no mounted drives in the future with the arrival of the EXADATA.
NO HARD DRIVE MOUNTED, NO ACCESS TO THE DATABASE DIRECTORIES
No UTL_FILE
I need to use the REEL spool the resulting XML data of the SELECT query.
SQL is a standard in my org, but I can do with a PL/SQL solution also to load data into a table (cannot use a COIL with PL/SQL)
What I do is:
- a column of type CLOB to a xml_report of the loading of the above SELECT query table
- Then using SELECT * FROM xml_report to SPOOL the data to a file report.xml
No need of XMLTYPE data behind. Xml data stream is fine for me.
In addition, I need to validate the XML file, also using XSD.
Problem is that the resulting lines of the select query are supposed to be from 15000 to 20000 bytes long.
Oracle database version: Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64 bit Production
A Suggestion or a solution to this problem would be appreciated.
(Sorry for the use of "BOLD", just to make it more readable and highlight the imp points)

You use the right method.
There is an implicit conversion from XMLType to the data type VARCHAR2 as expected by the function TO_CLOB, where the limitation, and the error.
To serialize XMLType to CLOB, use the XMLSerialize function:
SELECT XMLSerialize (DOCUMENT
XMLELEMENT ("accounts",
...
)
)
OF ANY_TABLE;
For the rest of the requirement, I wish you good luck trying to spool the XML correctly.
You may need to play around with the SET LONG and SET LONGCHUNKSIZE commands to operate.

I assumed that the XML can contain several "

export data from the table in xml files
Hello
This thread to get your opinion on how export data tables in a file xml containing the data and another (xsd) that contains a structure of the table.
For example, I have a datamart with 3 dimensions and a fact table. The idea is to have an xml file with data from the fact table, a file xsd with the structure of the fact table, an xml file that contains the data of the 3 dimensions and an xsd file that contains the definition of all the 3 dimensions. So a xml file fact table, a single file xml combining all of the dimension, the fact table in the file a xsd and an xsd file combining all of the dimension.
I never have an idea on how to do it, but I would like to have for your advise on how you would.
Thank you in advance.You are more or less in the same situation as me, I guess, about the "ORA-01426 digital infinity. I tried to export through UTL_FILE, content of the relational table with 998 columns. You get very quickly in this case in these ORA-errors, even if you work with solutions CLOB, while trying to concatinate the column into a CSV string data. Oracle has the nasty habbit in some of its packages / code to "assume" intelligent solutions and converts data types implicitly temporarily while trying to concatinate these data in the column to 1 string.
The second part in the Kingdom of PL/SQL, it is he's trying to put everything in a buffer, which has a maximum of 65 k or 32 k, so break things up. In the end I just solved it via see all as a BLOB and writing to file as such. I'm guessing that the ORA-error is related to these problems of conversion/datatype buffer / implicit in the official packages of Oracle DBMS.
Fun here is that this table 998 column came from XML source (aka "how SOA can make things very complicated and non-performing"). I have now 2 different solutions 'write data to CSV' in my packages, I use this situation to 998 column (but no idea if ever I get this performance, for example, using table collections in this scenario will explode the PGA in this case). The only solution that would work in my case is a better physical design of the environment, but currently I wonder not, engaged, as an architect so do not have a position to impose it.

Hello. Is it possible to export data from a table in Oracle using SQL Loader? If Yes, can you tell a good examples?
Hello
Hello. Is it possible to export data from a table in Oracle using SQL Loader?
No, with SQL * Loader, you can load data from external files into tables not export.
coil c:\temp\empdata.txt
sqlplusabc.sql (assumes that abc.sql runs select * from emp)
spool offIt cannot work like this, because the declaration of the COIL is not recognized outside the SQL * Plus the term.
But, you can include the statement of the COIL in abc.sql like this:
spool c:\temp\empdata.txt select * from emp; spool off
Then, you just have to run the SQL script as follows:
sqlplus
@abc.sql However, I advise you to use Oracle SQL Developer, this is a free tool and with it you can export a Table in several types of format (html, xml, csv, xls,...).
Please find attached a link to this tool:
http://www.Oracle.com/technetwork/developer-tools/SQL-Developer/Overview/index.html
Hope this helps.

How to publish data from a table using the form
Oracle forms6i
Hai All
I have download the data to the table of forms...
My table T1 columns are in, out, intrinsically, introut, empname, empno
and another table T2 consist of three columns is empno, date, time
In table T2 time fields consist of symbol I, o... I mean IN, O OUT
My Question is when an employee consist of 3 I - the three IN the time
0815 I, 1200 I, 1415 I and OUT 3 times O 1245, 1445 O, O 1715 and empno is 001
If there is no record for empno 001 then insert first 0815 I in table T1 in column IN time then
to update 1200 intrinsically and 1245 update to Introut and 1415 up-to-date addin and 1445 to update addout
Finally in 1715 to outtime
If it is possible to do without Hardcoding the moment Pls tell with some good example
Thanks in advance
Srikkanth.MThere now things are clear... whenever I have free I'll post the code u how to do this...
for now, a few tips can help u
-create the table to store operations travel so then u can't fix your code
-Create the cursor on the T1 line through all the records.
-Control what empno and action i.e. the current cursor (I or O) exists on the same date in T2 or not
-otherwise exists insert a new record check also the SHIFT is coming in time IF is between MAJ 0815 and 1645 and action is 'I' then insert record and column values accordingly
s ' there is, then update the record of the place where empno = cur.empno and attendance_date = mydate;
It may be useful

XML-aggregation and ORA-19011 (character string buffer too small)
Hello
I have a problem (ORA-19011) with a query that contains the data for each line through xmlagg().
You can find the query below. It works very well, until the t2.data aggregate becomes too big - that's when I get the error ORA-19011.
can someone give me a clue how to solve this problem through sql?
If not, can someone tell me what setting I have to adjust in the server-config to avoid this problem?
Thank you very much!

Impossible to delete the record from the table using the form
I have a stored procedure (function, actually) that allows an administrator to manually delete a record in a table.
When I call my form there will be no effect. The record remains in the table.
In both cases, I connect to the database to the same user.
I am able to call a test function in the database which returns a field in the record, so I think I can at least communicate with and retrieve results from the database using a stored function. As soon as I approach him "select" "delete from", no luck.
If I try to run the SQL in my form with a statement of FORMS_DDL, it seems to run smoothly when I not in the code in the debugger, but it had no effect. FORMS_SUCCESS reports TRUE if DBMS_ERROR_TEXT has the following: ORA-01403: no data found. I don't know how the DBMS_ERROR_TEXT is that FORMS_SUCCESS is not set to FALSE.
Any ideas as to why I am unable to remove using my form but can when you call the function registered directly/manually?
Using Oracle Forms & DB 10.0.2.0.1.Patrick,
After each Insert / Update / Delete statement, you have to COMMIT . Then only it will be in select statements.
Kind regards
Manu.
