Trying to insert CLOB data into Remote Table..

Hi everyone,
I think this question had already posted.But i am not able to figure out this problem..
what i am trying to do is
I have a table in the remote database with a CLOB column like this
REMOTE_TABLE
============
REMOTE_TABLE_ID (Populated with sequence)
REMOTE_CLOB CLOB
In my Local database i have to write a Procedure to gather some information on a particular record (My Requirement) and save that CLOB in the REMOTE_TABLE.
I built that procedure like this
Declare
var_clob CLOB; /* I need to processs several records and keep all data in a clob
begin
/***** Processed several records in a local database and stored in the variable var_clob which i need to insert into remote database ****/
Insert into remote_table@remote values (remote_table_seq.nextval,var_clob);
/*** when i try to execute the above command i am getting the following error
ORA-06550: line 6, column 105:
PL/SQL: ORA-22992: cannot use LOB locators selected from remote tables
ORA-06550: line 6, column 1:
PL/SQL: SQL Statement ignored *****/
/***For a test i created the same table in local db****/
Insert into local_table values (local_table_seq.nextval,var_clob);
It is working fine and i am able to see the entire CLOB what i want.
surprisingly if i pass some value instead of a varibale to the remote table like the following..
Insert into remote_table@remote values (remote_table_seq.nextval,'Hiiiiiiiii');
It is working fine...
I tried the following too..
decalre
var_clob clob;
begin
var_clob := 'Hiiiiiiiiiiiiiii';
Insert into remote_table@remote (remote_table_id) values (1);
commit;
update remote_table@remote set remote_clob = var_clob where remote_table_id = 1;
commit;
end
I am getting the following error..
ORA-22922: nonexistent LOB value
ORA-02063: preceding line from CARDIO
ORA-06512: at line 6
Could someone please help me in fixing this issue..I need to process all the data to a variable like var_clob and insert that clob into remote table..
Thanks in advance..

Error inserting CLOB data into xmltype table on Solaris 8 Oracle 9.2.0.1.0

Hi all,
I have a table t of type xmltype.
I have a function getData which parses an XML file and returns the CLOB data.
I have a statement as
"insert into t values(xmltype(getData('abc.xml')));"
I get the following error
ERROR at line 1:

Can anybody tell me what can be the problem.
Interestingly enough, the same things work on same Oracle version on Windows 2k, Windows 2k3, another Solaris 8 machine.
Please help asap as I am in fire fighting mode.

Hi Aniruddha
I think you need to post to a db forum rather than XMLP.

Insert the data into two tables at a time.

Hi ,
i have these two tables
create table [dbo].[test1](
[test1_id] [int] identity(1,1) primary key,
[test2_id] [int] not null
create table [dbo].[test2](
[test2_id] [int] identity(1,1) primary key,
[test1_id] [int] not null
alter table [dbo].[test1]
add constraint [fk_test1_test2_id] foreign key([test2_id])
references [dbo].[test2] ([test2_id])
alter table [dbo].[test2] add constraint [fk_test2_test2_id] foreign key([test1_id])
references [dbo].[test1] ([test1_id])
I want to insert the data into two tables in one insert statement. How can i do this using T-SQL ?
Thanks in advance.

You can INSERT into both tables within one Transaction but not in one statement. By the way, you would need to alter your dbo.Test1 table to allow null for first INSERT test2_id column
See sample code below:
CREATE TABLE #test1(test1_ID INT IDENTITY(1,1),test2_id INT NULL)
CREATE TABLE #test2(test2_ID INT IDENTITY(1,1),test1_ID INT)
DECLARE @Test1dentity INT
DECLARE @Test2dentity INT
BEGIN TRAN
-- Insert NULL as test2_ID value is unknown
INSERT INTO #test1(test2_ID)
SELECT NULL;
-- get inserted identity value
SET @Test1dentity = SCOPE_IDENTITY();
INSERT INTO #test2(test1_ID)
SELECT @Test1dentity;
-- get inserted identity value
SET @Test2dentity = SCOPE_IDENTITY();
-- Update test1 table
UPDATE #test1
SET test2_ID = @Test2dentity
WHERE test1_ID = @Test1dentity;
COMMIT
SELECT * FROM #test1;
SELECT * FROM #test2;
-- Drop temp tables
IF OBJECT_ID('tempdb..#test1') IS NOT NULL
BEGIN
DROP TABLE #test1
END
IF OBJECT_ID('tempdb..#test2') IS NOT NULL
BEGIN
DROP TABLE #test2
END

Hello,
What manu suggested this can be done through oracle forms.
If as i read your last post you are using that in database it will not work in db. Try to use the same process in oracle forms will work by making some changes.
And if you don't want to use forms then there is one way using SQL LOADER. It required control file to execute for uploading data.
See the below link.
http://www.orafaq.com/wiki/SQL*Loader_FAQ
In this example its showing filename.csv you can use your file name like yourfilename.txt.
So your control file will look like this...
load data
infile 'file_path\file_name.txt'
into table table_name -- use actual table name where you want to upload data
fields terminated by " " -- Here using spaces as you mentioned
(column1, column2, column3) -- Here use the three column names of tableAnd after creating control file with the above code. You can call it in command prompt like this
sqlldr username/password control=control_file_path\control_file_name.ctl log=log_file_path\log_file_name.log
or
sqlldr username/password@dbconnection control=control_file_path\control_file_name.ctl log=log_file_path\log_file_name.log
Before doing this practice make sure SQLLDR.exe availabe in the machine where you have to execute. Otherwise you will have to install db client for using sqlldr.exe

Trigger to insert unique data into other table (having more than 40 millions of records) - MYSQL

Hi All,
i am facing impact of trigger in MYSQL, scenario is this:
I am Having one table with duplicate records that is consist of (eid,tin,status and some other columns are also there but i need only these three). there is another table which is having same these three columns (eid, tin, status).
eid and tin will be same for given combination only status will be different i.e.
1245 23 0
1245 23 1
1245 23 5
1233 33 3
1211 24 2
1211 24 5
so as per above example i have to feed data into other table as
1245 23 0
1233 33 3
1211 24 5
priority of status is like 0 will be inserted if that is present in record otherwise it will be decrease from 5 to 1.
so i have designed trigger for this which will insert data after reading each row, but it is taking around 6.5 minutes for inserting 300000 records. so is there any other way to improve performance for this mysql program.

Hello everyone,
I have a trouble about JSP. I'm using Java2 SDK,JSP 1.2,Mysql and TOMCAT.
I want to do this. A user has to enter the nicno,into the html form(EnterNicInter.jsp),to verify if it is already exist or not. If it is exist in the db, an error msg(Record already exist) must be displayed. If not, then the page "InterviewForm.jsp" displayed. This part is working.

Thanks.

you should try something different, since you are mixing up a lot of code.
1) create a separate method just to connect and disconnect from a database;
2) use the value entered and see if you can find a record in the table. If the record is there, then you should re-direct your jsp to a jspError, else goes to another form.
the code below give you some idea
      if( sAction.equals("Add1") ) {
        sITEM = request.getParameter("parameter1");
        try {
          itemmaster.connect();
          itemmaster.viewitemmaster( sITEM );
          rs = itemmaster.getRs();
          if( rs.next() ) {
            sURL = "additemmaster1.jsp";
          else {
            request.setAttribute( "asITEM", sITEM );
            sURL = "additemmaster2.jsp";
        finally {
          rs.close();
          itemmaster.disconnect();
      }

Insert XML data into oracle table

I want to insert xml data returned by the VB code into oracle table.
As a prequisite I have installed the XDK capabilities for Oracle by installing JServer & running
SQL scripts catxsu.sql,xmlparserv2.jar,load.sql to load the XMLSQL Utility (DBMS_XMLQuery) into the database.
I have also granted following privileges to the user.
Grant users access to XMLParser and XMLDom packages:
     grant execute on xmldom to public;
     grant execute on xmlparser to public;
     create public synonym xmldom for sys.xmldom;
     create public synonym xmlparser for sys.xmlparser;
But still i am not able to create procedure which will accept input parameter as an XML document coming from front end which in turn will insert that record into simple oracle table . I am using Oracle 8.1.7
Thanks in advance

Would you specify the database version?
Since DBMS_XMLSave requires DOM, you normally need to divide the huge XML before insertion.

How do I insert input data into anoracle table using C#

Hi guys,
I am new in the .NET arena and I am using Visual Studio 2005 Pro edition.. For instance I have 2 forms one being the main form which calls another to to insert captured text onto a form with the idea of passing it into the oracle database. I am failing to do that using C#. Where am I going wrong? Part of the code when I use actual values, data is written but when I want to write from input text from the form I get an Oracle message ORA-00936. A global connection is established in the first form.
Here is the successful code:
Try
MyCmd.CommandText="insert into station (stn_abb,stn_no,stn_name)"+
"values('MUT','0480','MUTARE')";
Int rowsUpdated = MyCmd.ExecuteNonQuery();
If (rowsUpdated == 0)
MessageBox.Show("RECORD NOT WRITTEN");
Else
MessageBox.Show("RECORD WRITTEN TO TABLE");
Txn.Commit();
Here is the UNSUCCESSFUL code:
Try
MyCmd.CommandText = "insert into station (stn_abb,stn_no,stn_name)" +
"values(@txtStnAbb.Text,@txtStnNo.Text,@txtName.Text)";
Int rowsUpdated = MyCmd.ExecuteNonQuery();
If (rowsUpdated == 0)
MessageBox.Show("RECORD NOT WRITTEN");
Else
MessageBox.Show("RECORD WRITTEN TO TABLE");
Txn.Commit();
Regards,
Ray.

Hi,
I assume that in the second example your intent is to use bind variables, but I dont see where you're actually binding any variables. Also, "@" is sqlserver syntax, Oracle's syntax is ":".
Here's a complete example, hope it helps.

Insert CSV data into a table from URL

Hi,
How can I insert the CSV data directly into a database table (the csv format is known, the database table is created accordingly)?
Thanks
Devang.

Devang,
There is a limit on the amount of text (32767) you can paste and upload.
I created a process that allows the user to upload a .csv file and it is then written (UTL_FILE) to a known file on the db server. I have an external table definition mapped to that file so I don't have to do any parsing or anyting.
This should work for your situation since you already know the format of the file and the table is already created.
Hope this helps.

1. Inserting String data into XMLType column - if the value is more than 4000 chars, it gives an error
2. Inserting CLOB Data into XMLType column - Using the OracleCLob option in the deployment descriptor results in a SQLExcepotion Inconsistent datatype expected number found CLOB.
Can anybody provide a solution to this problem?
