Pool data from text file and insert into database

Can anyone tell me how to pool data from a text file and insert into database?
let's say my text file is in this format
123456 Peter 22
234567 Nicholas 24
345678 Jane 20
Then I need to insert the all the value for this three column into a table which has the three column name ID, Name, Age
Anyone knows? I need to do this urgently...Thank in advanced

1. Use BufferedReader and read the file line by line.
2. Loop thru the file and do the following steps with in this loop.
3. Use StringTokenizer to seperate each line into three values (columns).
4. Now create a insert statement with these values and add the statement to the batch (using addBatch() method of PreparedStatement or Statement).
5. Finally (after exiting the loop), execute these batch of statements (using ps.executeBatch()).

Hi, extract data from xml file and insert into another exiting xml file

i am searching code to extract data from xml file and insert into another exiting xml file by a java program. I understood it is easy to extract data from a xml file, and how ever without creating another xml file. We want to insert the extracted data into another exiting xml file. Suggestions?

RandomAccessFile? If you know where you want to insert it.Are you sure about this? If using this, the receiving file would have to have bytes inserted that exactly match the number of bytes replaced. I'm thinking that you'll likely have to stream through the second XML with a SAX parser and copy information (or insert new information) as you stream with an XML writer of some sort.

If the files are small, you can load the target file in a DOM document, insert the data from the source file and persist the DOM.
If the files are large, you probably want to use a StAX or SAX.

When you get an error with external tables (or sql*loader) look in the same folder as the data file and you should get a .log file and maybe a .bad file too.
The log file should indicate the nature of the error it has trying to load the data.
I've just copied your sample data from your first post to a file on my server and tried it to find that you are not specifying the required format for your dates. The below shows it now working...

Sure.
Which part don't you understand?
1. Reading a text file
2. Parsing the text file contents.
3. Relational databases and SQL.
4. How to create a database.
5. How to connect to a database in Java.

Reading data From XML file and setting into ViewObject to Pouplate ADF UI

Hi,
I have following requirement.
I would like to read data from XML file and populate the data in ViewObject so that the data can be displayed in the ADF UI.
Also when user modifies the data in the ADF UI, it should be modified back into to ViewObject.
Here is an example - XML file contains Book Title and Author. I would like to read Book Title and Author from XML file and set it into ViewObject Attribute and then display Book title and Author in ADF UI page. Also when user modifies Book title and Author, I would like to store it back in View Object.
Please help me with this requirement and let me know if any solution exist in ADF, for populating the ADF UI screen fields with external XML file data.
Thanks

Read data from E$ table and insert into staging table

Hi all,
I am a new to ODI. I want your help in understanding how to read data from an "E$" table and insert into a staging table.
Scenario:
Two columns in a flat file, employee id and employee name, needs to be loaded into a datastore EMP+. A check constraint is added to allow data with employee names in upper case only to be loaded into the datastore. Check control is set to flow and static. Right click on the datastore, select control and then check. The rows that have violated the check constraint are kept in E$_EMP+ table.
Problem:
Issue is that I want to read the data from the E$_EMP+ table and transform the employee name into uppercase and move the corrected data from E$_EMP+ into EMP+. Please advise me on how to automatically handle "soft" exceptions in ODI.
Thank you

Hi Himanshu,
I have tried the approach you suggested already. That works. However, the scenario I described was very basic. Based on the error logged into the E$_EMP table, I will have to design the interface to apply more business logic before the data is actually merged into the target table.
Before the business logic is applied, I need to read each row from the E$EMP table first and I do not know how to read from E$EMP table.

Getting data from some source and insert into corresponding source

hi all,
i am using db10g.
i have like like
MMA : add1:add2:add3'the above said is the format and actual data will be something like
MMA : bank street : no:32 : tel: +9127546663
add1 = bank street
add2 = no:32
add3 = tel: +9127546663 my requirement to store add1,add2 and add3 into the table.
So to take the data i am using substring and instring function to get the data with respect to : my problem is for example in add2 place no:32 is there my task is to fetch the no:32 from that line and store into the table as no:32 only in that case i cannot fetch the value in terms of :.
sincr : is the delimiter(seperator for data element)
how can i solve this issue?
Thanks..

Your first addr1 is terminated by (:).
your second addr2 is started with (no:), and also terminated by (:)
and third addr3 is started with (tel:).
only the first and third (:) will be used as delimiter, so how about this?
WITH T AS (SELECT 'bank street:no:32:tel:+9127546663' AS STR FROM DUAL)
SELECT SUBSTR(STR, 1, INSTR(STR, ':', 1, 1)-1) AS ADD1,
SUBSTR(STR, INSTR(STR, ':', 1, 1)+1, INSTR(STR, ':', 1, 3)-INSTR(STR, ':', 1, 1)-1) AS ADD2,
substr(str, instr(str, ':', -1, 2)+1) as add3 from t;
bank street no:32 tel:+9127546663Or can`t you just ask the people who gave the requirement to change the delimiter used in the format to something else like pipe (|)?

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.

Fetch data from one table and insert into two tables in desired format

I have similar to the following data in a table and it is not normalized. The groupID is being used to group two records of similar nature.
DECLARE @OldDoc TABLE (oldDocID INT, groupID INT, deptID INT)
INSERT INTO @OldDoc (oldDocID, groupID) VALUES (1, NULL, 111),(2,NULL,111),(3,1,111),(4,NULL,333),(5,1,222),(6,NULL,333),(7,2,222),(8,2,333),(9,NULL,111),(10,3,222),(11,NULL,333),(12,3,444)
I need to process the data from the above table (@OldDoc) and write into two new tables (@NewDoc and @NewDocGroup) as follows.
oldDocID should be stored as newDocID when inserting to @NewDoc table. Only records with groupID NULL and one record (first one) per group should be considered (For example, oldDocID 5 is not considered as 3 and 5 belong to the same groupID 1) for insertion.
DECLARE @NewDoc TABLE (newDocID INT)
INSERT INTO @NewDoc (newDocID) VALUES (1),(2),(3),(4),(6),(7),(9),(10),(11)
All records from @OldDoc should be considered for insertion into @NewDocGroup table. OldDocID is inserted as NewDocID and deptID is as-is. Instead of groupID, the ID of the first record in the
group should be considered as parentNewDocID (For example, 3 is considered as parentNewDocID for newDocID 5 as 3 and 5 belong to the same groupID in @OldDoc table) for the newDocID.
DECLARE @NewDocGroup (newDocID INT, parentNewDocID INT, deptID INT)
INSERT INTO @NewDocGroup (newDocID, parentNewDocID, deptID) VALUES (1,1,111),(2,2,111),(3,3,111),(4,4,333),(5,3,222),(6,6,333),(7,7,222),(8,7,333),(9,9,111),(10,10,222),(11,11,333),(12,10,444)
How do I accomplish the above using SQL ? Thanks for the help.

>> I have similar to the following data in a table and it is not normalized. The group_id is being used to group two records [sic] of similar nature. <<
Rows are not records. Tables have to have a key by definition. You do not do math with identifiers, so they should not be numeric. Let's ignore that error for now. In short, you are posting garbage. If you had followed Forum Netiquette, would you have posted
this?
CREATE TABLE Old_Documents
(old_doc_id INTEGER NOT NULL PRIMARY KEY,
group_id INTEGER,
dept_nbr INTEGER NOT NULL
REFERENCES Departments (dept_nbr));
INSERT INTO Old_Documents(old_doc_id, group_id, dept_nbr)
VALUES (1, NULL, 111),
(2, NULL, 111),
(3, 1, 111),
(4, NULL, 333),
(5, 1, 222),
(6, NULL, 333),
(7, 2, 222),
(8, 2, 333),
(9, NULL, 111),
(10, 3, 222),
(11, NULL, 333),
(12, 3, 444);
>> I need to process the data from the above table (Old_Documents) and write into two new tables (New_Documents and New_Documents_Groups) as follows. <<
Just like punch cards and mag tape data processing! Being old and being new are a status, not another kind of entity. But that is how mag tapes work. And you even use the verb "fetch" from tape files. This design flaw is called attribute splitting.
Do you have a Male_Personnel and Female_Personnel table? NO! It is just Personnel!
>> old_doc_id should be stored as new_doc_id when inserting to New_Documents table. Only records [sic] with group_id NULL and one record [sic] (first [sic; no ordering in a table] one) per group should be considered (For example, old_doc_id 5 is not considered
as 3 and 5 belong to the same group_id =1) for insertion. <<
Think about your punch card mindset. Why did you physically materialize that redundant New_Documents table? Let me answer that: this is how you work with punch cards! In SQL we use a VIEW:
CREATE VIEW New_Documents (new_doc_id)
AS
SELECT old_doc_id
FROM Old_Documents;
>> All records [sic] from Old_Documents should be considered for insertion into New_Documents_Groups table. The old_doc_id is inserted as new_doc_id and dept_nbr is as-is. Instead of group_id, the ID [sic: which identifier??] of the first [sic: tables
have no ordering like a deck of punch cards] record [sic] in the group should be considered as parent_new_doc_id (For example, 3 is considered as parent_new_doc_id for new_doc_id 5 as 3 and 5 belong to the same group_id in Old_Documents table) for the new_doc_id.
<<
Why not use 5 as the parent? My guess is that you are trying to form equivalence classes. See:

How to read the data from excel file and store into the table?

Hi All,
I have table with BLOB datatype contains a excel file. I have to read that data from excel and store into one table with all the fields in excel.
All the excel fields and my table columns are same.
Can you share with me how can acheive this using LOB's?
Thanks

Hi OraSuirya,
you can try with external tables .
syntax as follows
create table ext_table_csv (
i Number,
n Varchar2(20),
m Varchar2(20)
organization external (
type oracle_loader
default directory ext_dir
access parameters (
records delimited by newline
fields terminated by ','
missing field values are null
location ('file.csv')
reject limit unlimited;
For this you need to create directory
Directory Creation syntax:
create or replace directory ext_dir as 'D:\oracle\user_dir\ext_dir';
grant read, write on directory ext_dir to <User>;
please paste the excel file in the particular directory .
I hope this will help you.
Please correct me if I am wrong anywhere .
Thanks,
Tippu.
