@OP,
I have a Clob file as a in parameter in my PROC. . File is comma separated.need procedure that would parse this CLOB variable and populate in oracle table .You don't have a "clob file" as there's no such thing. CLOB is a datatype for storing large character based objects. A file is something on the operating system's filesystem.
So, why have you stored comma seperated data in a CLOB?
Where did this data come from? If it came from a file, why didn't you use SQL*Loader or, even better, External Tables to read and parse the data into structured format when populating the database with it?
If you really do have to parse a CLOB of data to pull out the comma seperated values, then you're going to have to write something yourself to do that, reading "lines" by looking for the newline character(s), and then breaking up the "lines" into the component data by looking for commas within it, using normal string functions such as INSTR and SUBSTR or, if necessary, REGEXP_INSTR and REGEXP_SUBSTR. If you have string data that contains commas but uses double quotes around the string, then you'll also have the added complexity of ignoring commas within such string data.
Like I say... it's much easier with SQL*Loader of External Tables as these are designed to parse such CSV type data.

1.is it possible to read a .xls file and load it into an oracle table

1.is it possible to read a .xls file and load it into an oracle table, using oracle database or oracle forms i.e. either utl_file, or text_io, or any other oracle tool.
As far as I know we need a csv file or a txt ( tab delimited) file ?
2.Are there any windows tools for the same

Hi,
If you want to use the DDE package to read the XLS file then yes, you will neeed to know the number of rows and columns in the input file.
i.e. How will you know :
1) How many columns are there in the input file.
If I have a XLS file with the following data :
R1C1 R1C2 R1C3 R1C4 R1C5 R1C6 R1C7
xxx xx x
Where R represents row and C represents column, then how will you know the each row has 7 columns. If you know the answer upfront, then it's not a issue.
Using the DDE apprach, you will have to specify the RowNum and the ColumnNo of each idividual cells to read/write data from xls sheet.
Look at the syntax in my ealier post.
using the other approch (i.e. comma delimited text file - CSV file) , you need not know the number of columns as you can loop thru the input record till the last column is read.
All you have to do is to look for the 'n' occurances of the field delimiter say ',', do a substr from the current position to the point where the ',' was found.
This process is to be repeated in a loop till all columns are read.
The TEXT_IO package can trap for EOF (End Of File).
Hope I made myself clear.

Drop, create and insert data into few intermediate tables

Hi All,
I need to schedule a process to drop, create and insert data into few intermediate tables on a weekly basis. Here is what i need to do in the stored procedure, which can be scheduled weekly.
DROP TABLE TABLE_NAME1;
DROP TABLE TABLE_NAME2;
DROP TABLE TABLE_NAME3;
CREATE TABLE TABLE_NAME1
CREATE TABLE TABLE_NAME2
CREATE TABLE TABLE_NAME3
INSERT INTO TABLE_NAME1 SELECT ....;
INSERT INTO TABLE_NAME2 SELECT ....;
INSERT INTO TABLE_NAME3 SELECT ....;
Any suggestions, examples or code on how to accomplish this task would be very helpful. Any question pls let me know.
Thanks in advance.

I am using the intermediate tables in an extract process. The idea was that the table would be created prior to calling the extract procedure and once the data written to the intermediate table had been processed the table would be dropped. This would be repeated each time the extract process is run. From a DBA's point or view, would it be better to just leave the table on the database and truncate it after each run or is removing it entirely best?

SQL server 2014 and VS 2013 - Dataflow task, read CSV file and insert data to SQL table

Hello everyone,
I was assigned a work item wherein, I've a dataflow task on For Each Loop container at control flow of SSIS package. This For Each Loop container reads the CSV files from the specified location one by one, and populates a variable with current
file name. Note, the tables where I would like to push the data from each CSV file are also having the same names as CSV file names.
On the dataflow task, I've Flat File component as a source, this component uses the above variable to read the data of a particular file. Now, here my question comes, how can I move the data to destination, SQL table, using the same variable name?
I've tried to setup the OLE DB destination component dynamically but it executes well only for first time. It does not change the mappings as per the columns of the second CSV file. There're around 50 CSV files, each has different set off columns
in it. These files needs to be migrated to SQL tables using the optimum way.
Does anybody know which is the best way to setup the Dataflow task for this requirement?
Also, I cannot use Bulk insert task here as we would like to keep a log of corrupted rows.
Any help would be much appreciated. It's very urgent.
Thanks, <b>Ankit Shah</b> <hr> Inkey Solutions, India. <hr> Microsoft Certified Business Management Solutions Professionals <hr> http://ankit.inkeysolutions.com

The standard Data Flow Task supports only static metadata defined during design time. I would recommend you check the commercial COZYROC
Data Flow Task Plus. It is an extension of the standard Data Flow Task and it supports dynamic metadata at runtime. You can process all your input CSV files using a single Data Flow Task
Plus. No programming skills are required.

Using servlets to read from text file and insert data

Hi,
Can I use a servlet to read from a space delimited text file on the client computer and use that data to insert into a table in my database? I want to make it easy for my users to upload their data without having to have them use SQL*Loader. If so can someone give me a hint as how to get started? I appreciate it.
Thanks,
Colby

Create a page for the user to upload the file to your webserver and send a message (containing the file location) to a server app that will open the file, parse it, and insert it into your database. Make sure you secure the page.
or
Have the user paste the file into a simple web form that submits to a servlet that parses the data and inserts it into your db.

How to read a txt file then insert them into db tables

Hi,
Please help me to solve this problem. This is what I need to do:
1. read a text file which holds the values to be inserted into some database tables. For example it holds ename, deptno, sal, dname for emp and dept tables. These are in a text file now.
2. Then I need to insert these data into db tables like emp and dept, and check if there are dups or voilate any constraints. The records to be inserted are usually > 100,000, so I am also looking for a fast way to do this.
3. This operation happens regularly, so I need to schedule the job. I know this can be done by using procedures and dbms_jobs.
Any help will be greately appreciated.

Generally, in 8i, folks would use sql loader to accomplish this. Sql loader does exactly what you want, but is an external application, so it would probably be easiest to schedule it to run using your operating system's scheduler (i.e. cron on Unix, Task Scheduler on Windows). You could certainly write a PL/SQL procedure that called the external sql loader application, and use the Oracle scheduler to schedule it, but that strikes me as more effort than it's worth.
If you're using 9i, you could look into external tables, which would simplify the process greatly.

You can setup an ODBC connection to the Excel file and update the file with JDBC, using the JDBC-ODBC bridge.
Hope this helps

Reading file and dump data into database using BPEL process

I have to read CSV files and insert data into database.. To achieve this, I have created asynchronous bpel process. Added Filed Adapter and associated it with Receive activity.. Added DB adapter and associated with Invoke activity. Total two receive activity are available in process, when tried to Test through EM, only first receive activity is completed, and waiting on second receive activity. Please suggest how to proceed with..
Thanks, Manoj.

Deepak, thank for your reply.. As per your suggestion I created BPEL composite with
template "Define Service Later". I followed below steps, please correct me if I am wrong/missing anything. Your help is highly appreciated...
Step 1-
Created File adapter and corresponding Receive Activity (checkbox create instance is checked) with input variable.
Step 2 - Then in composite.xml, dragged the
web service under "Exposed Services" and linked the web service with Bpel process.
Step 3 - Opened .bpel file and added the DB adapter with corresponding Invoke activity, created input variable. Web service is created of Type "Service" with existing WSDL(first option aginst WSDL URL).
and added Assign activity between receive and invoke activities.
Deployed the composite to server, when triedTest it
manually through EM, it is promting for input like "subElmArray Size", then I entered value as 1 with corresponding values for two elements and click on Test We Service button.. Ptocess is completing in error. The error is

Insert data into msql thru table trigger

Hi,
I installed dg4msql 11.2 and I would like to insert some data into our msql thru one of our Oracle table after insert table,
I used the syntax below
insert into test@dg4msql ("PN") values (:new.PN)
but the below error problem if I insert data into my Oracle table,
ORA-02054: transaction 4.17.15898 in-doubt
ORA-028500, connect from ORACLE to a non-Oracle system returned this message
[Oracle][ODBC SQL Server Driver][SQL Server] Invalid object name "RECOVER.HS_TRANSACTION_LOG
Do I have to create the HS_TRANSACTION_LOG table in my msql server to resolve this problem?
Thanks
Vincent

Vincent,
If the gateway insert is being done as part of a trigger then it will almost certainly be part of a distributed transaction so yes, you will have to create the transaction log table and the recovery user in the SQL*Server database.
As well as the gateway documentation have a look at this note in My Oracle Support -
Note.227011.1 How to Setup DG4MSQL to Use Distributed Transactions (Doc ID 227011.1)

How to insert data into the mysql table by giving as a text file

Hi,
Any one know's how to insert data into the mysql table by giving as a text file as the input in JSP.Please respond ASAP.
Thanks:)

At least you can try StringTokenizer to parse your text files. Or download a text JDBC driver to parse your files, for instance, HXTT Text(www.hxtt.net) or StelsCSV(www.csv-jdbc.com).
