JDeveloper, Java & XML :: Load Huge XML File With Hundreds Of Records Into Oracle Table?
Jun 29, 2011
I need to load (using SQL Loader) an huge XML file, with several hundreds of records into an Oracle Table.The XML file schema is pretty simple, and it's anything like this:
<dataroot>
<record>
<companyname>LimitSoft S.A.</companyname>
<address>Street Number 1</address>
[code]...
I'm trying to use the help included in this link [URL]...
When they refer to schema[URL].... what should I use?? I do not need to use the Oracle website to register anything, right?
XML has a parent element Interaction and each Interaction has different elements like Consumer, Campaign, Response, Survey, MultiSuppressions. Now i need to insert Consumer element data into table1, Response and Campaign elements data into table2, Survey data into Table3 and Multisuppression data into table4 with interaction number (this can be rownumber) so that i can link all the tables based on interaction number.
I googled on parsing xml and found xmltable can be used to parse xml. I wrote below procedure, but it will not work if i include MultSuppressions (will get cartesians).
I've got a table with XML code (CLOB column) and I need to read and write every of parameter(blue marked below) and value (red marked below) record from that.
I need an example of oracle stored procedure, which should xmltype input parameter. xml type parameter contains multiple records and I need to update them in the database.
I am writing a java stored procedure in my package. In the java procedure I want to issue a query to be fired on the user table from which I am calling the java procedure.
Some thing like following:
I am logged in to USER1 and my package is inside USER1. From this package I am calling the Java Stored Procedure. In java procedure I want to make a jdbc connection to USER2. The details of USER2(password, hostname,portno) are stored in a table called 'connection_details' and this table is in the USER1.
My problem is how can I issue the
SELECT details FROM CONNECTION_DETAILS for USER2
so that i can get the details..?
Do i need to first make jdbc connection to USER1 and then execute the above query for which i need similar details of USER1. How can i obtain the details of USER1 here.
I am thinking if I am already in USER1 then do I need to make the jdbc connection to USER1 and then execute the query?
Consider tables A,B,C,D,E,F. all are having 100000++ records Tables B,C,D are dependent on table A (with foreign key constraint). When I am deleting records from all tables, table B,C,D are taking max 30-40 seconds while table A is taking 30-40 mins. All tables are having indexes.
Method I have used:
1. Created Temp table
2. then deleted all records from B,C,D,E,F for all records in temp table for limit of 500.
delete from B where exists (select 1 from temp where b.col1=temp.col1);
3. why it is taking too much time for deleting records in table A.
I was reading a tutorial for AJAX after I read another for javascript and thought, what if you could use void(0) in the URL part of AJAX so you can get a dynamic local page. AJAX reloads just a certain part of whatever you want, but it gets a file from a server.

if there is any package provided with DB that would allow me to import XML file and then use XPath to read the data? I need to insert it in proper tables then. I could see packages to create XML files, but I could not see any one to load it from the file. I could see it could be done in Java using XMLDOM, but is there any way of doing this using pure PL/SQL?
I have used jaxb (used xjc.exe ) to parse a XML schema file.However after the class files were generated,one of the setter method is missing.Is it possible that this can happen or have i done something wrong.
The classes that got generated are (snippet of it) public class Shiporder { @XmlElement(required = true) protected String orderperson; @XmlElement(required = true)

i have a problem in my ODI 11g with the load into Oralce table of a fixed width file, i configured all the datasource in ODI and when i do view data i see all correct, the end of file is signed like "0D0A" but when i try my load interface i receive the message that my last field is more big than the one declared.
My file have an header of fields and the last field is a data-field of 2000 characters. I controlled and is really fixed the length cause is a COBOL file from a Mainframe. So it looks that ODI don't understand the end of that field and go ahead to the other, i just tryed to enlarge the limit but is always more big like if the file is shifting on the right.
Have i forgot some configuration in some place? The definition of the file present the end of file like Microsoft hexadecimal \u000D\u000A i try all the combination there but no way to avoid this problem.
I am having query regarding sql loader. my data file is comm(,) seperated and I want to load the whole file in oracle table 'bill_temp' except 1st column data of data file.

Here I want load the emp_name,emp_sal and join_date into oracle table bill_temp. emp_id should not get loaded into table.
