Loading a CLOB from a CSV file into Oracle

I'm consuming data files from a third party and I need to load them into an Oracle database. One of the files has a field that's described in the data dictionary as varchar2(8000) which will obviously need to be stored as a CLOB.
I have two questions:
1. How do I create a Model for the data file when CLOB isn't available as the Type of a column.
2. Will I need to do anything fancy to get it into a CLOB column in an Oracle table? I'm using "LKM File to Oracle (SQLLDR)" and "IKM Oracle Incremental Update (PL SQL)"

I ended up running the file through a Java app to trim the field down to 4000 characters.
I can't believe an Oracle product can't handle an Oracle data type - very poor.

How can I import data from a csv file into databse using utl_file?

Hi,
I have two machines (os is windows and database is oracle 10g) that are not connected to each other and both are having the same database schema but data is all different.
Now on one machine, I want to take dump of all the tables into csv files. e.g. if my table name is test then the exported file is test.csv and if the table name is sample then csv file name is sample.csv and so on.
Now I want to import the data from these csv files into the tables on second machine. if I've 50 such csv files, then data should be written to 50 tables.
I am new to this. Could anyone please let me know how can I import data back into tables. i can't use sqlloader as I've to satisfy a few conditions while loading the data into tables. I am stuck and not able to proceed.
Please let me know how can I do this.
Thanks,
Shilpi

Why you want to export into .csv file.Why not export/import? What is your oracle version?

Trying to import from different csv files into multiple JTables

This might seem like something that isn't commonly done, but I'll see if anyone has done this before anyways.
I currently have a JTable (tab #1) and it successfully reads in the data from a CSV file to populate the cells. Now, I am looking into making 3 more JTables. I can tab between the four different tables, but I can't seem to figure out how to get the data to go to the correct JTable. Tab #1 = table, Tab #2 = table2, Tab #3 = table3, Tab #4 = table4.
Thanks.
 try
 FileInputStream fileInput = new FileInputStream ("upcoming.csv");
 BufferedReader InputCSV = new BufferedReader (new InputStreamReader (fileInput));
 line = InputCSV.readLine(); //start reading into the records.
 //Create data for the table.
 //the row variable = starting row
 int row = 0;
 while(line != null)
 tmp = line.split(",");
 for (int col = 0; col < columnNames.length; ++col)
 data[row][col] = tmp[col]; //store cells' data to the 2-dimensional array.
 row++;
 line = InputCSV.readLine();
 }//end of WHILE-statement.
 } //END of TRY-statement.
 catch(Exception e)
 System.out.println(e);
 }

I have been successful in my quest to get 4 different datasets into 4 different JTables. The previous posters suggestion to use the Table model led me to this page:
http://java.sun.com/j2se/1.5.0/docs/api/javax/swing/table/TableModel.html
 TableModel myData = new MyTableModel();
 JTable table = new JTable(myData);I had some very similar code in my program. I use the DefaultTableModel and the SortFilterModel before having 4 different JTables.
 DefaultTableModel model = new DefaultTableModel(data, columnNames);
 DefaultTableModel model2 = new DefaultTableModel(data2, columnNames);
 DefaultTableModel model3 = new DefaultTableModel(data3, columnNames);
 DefaultTableModel model4 = new DefaultTableModel(data4, columnNames);I use the code in the first post 4 times, and only change the filename and the data#.
I also have some code that counts the number of lines that will be needed.
Thanks.

Hi everyone!
The following are the steps to load a excell sheet to oracle table.i tried to be as simple as possible.
thanks
Step # 1
Prapare a data file (excel sheet) that would be uploaded to oracle table.
"Save As" a excel sheet to ".csv" (comma seperated values) format.
Then save as to " .dat " file.
e.g datafile.bat
1,Category Wise Consumption Summary,Expected Receipts Report
2,Category Wise Receipts Summary,Forecast Detail Report
3,Current Stock List Category Wise,Forecast rule listing
4,Daily Production Report,Freight carrier listing
5,Daily Transactions Report,Inventory Value Report
Step # 2
Prapare a control file that define the data file to be loaded ,columns seperation value,name and type of the table columns to which data is to be loaded.The control file extension should be " .ctl " !
e.g i want to load the data into tasks table ,from the datafile.dat file and having controlfile.ctl control file.
SQL> desc tasks;
Name Null? Type
TASK_ID NOT NULL NUMBER(14)
TASK_NAME VARCHAR2(120)
TASK_CODE VARCHAR2(120)
: controlfile.ctl
LOAD DATA
INFILE 'e:\datafile.dat'
INTO TABLE tasks
FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '"'
(TASK_ID INTEGER EXTERNAL,
TASK_NAME CHAR,
TASK_CODE CHAR)
The above is the structure for a control file.
Step # 3
the final step is to give the sqlldr command to execute the process.
sqlldr userid=scott/tiger@abc control=e:\controlfile.ctl log=e:\logfile.log

Can't paste copied entries from online CSV file into Excel spreadsheet (chatted with zzxc on 5/3/10 at around 2.30 CST but got disconnected. did not get an answer ...)

Here is the transcript of a chat with Firefox community member zzxcon May 3/10
You are now chatting with Firefox community member zzxc
zzxc: Hello
zzxc: What happens when you attempt to download a .csv file?
seegal: hello
seegal: it doesn't copy
zzxc: how are you trying to copy?
seegal: pls bear with me I'm a slow typist. Just copy selected text
Biolizard has joined the conversation.
zzxc: ok - which text are you selecting?
seegal: I reconcile my checkbook (spreadsheet this way). I copy the items in my online bank acc and paste it to the spreadsheet
seegal: I'm using Firefox /2.0.0.19. Have no problem to do this.
zzxc: Which version of OS X?
seegal: In all newer version nothing happens when trying to paste- just doesn't paste
zzxc: Firefox 2.0.0.x is no longer supported, and hasn't been supported in over a year
zzxc: Paste into Excel, from Firefox?
seegal: Sorry, I'm ahead... /2.0.0.19
seegal: Yes. I open my bank acc in Firefox
zzxc: Which version of Excel?
zzxc: It would really help if you could tell me step by step what you're doing.
seegal: First re: your previous question: it's OS 10.4.11
seegal: About Excell: it'as 2004 version - the lasat one produced for Macs. The specific version is 11.3.7
seegal: So I open my bank acc online in Firfox (my primary browser). I copy the latest entry in the account and paste it into my Excel spreadsheet.
zzxc: so, you copy direct from the web page without downloading a CSV file?
seegal: What do you mean by downloading to CSV file? I could export from the https://chat-support.mozilla.com:9091/webchat/getimage?image=sendmessage&workgroup=support%40workgroup.chat-support.mozilla.comFirefox to the CSV file, but the other way around?
zzxc: Are you copying your bank statement directly from the web site to Excel using the clipboard?
seegal: sI don't use the clipboard. This is a mac. There is no need to do that. In PC it would be yes.
zzxc: I need to know the exact steps you're taking to get them into excel
zzxc: And I need to know what exactly goes wrong in the latest version of Firefox.
seegal: Do you have a mac there with Firefox and Excel? It would be very easy to reproduce. Imagine you open an online bank acc, select some entries , click "copy", than proceed to your already open Excel spreadsheet and click' paste". That's it!
zzxc: When this happens, do you get cryptic code pasted into Excel?
seegal: As I said before: in all newer versions starting with 3.0 when I go to Excel to "paste" from my bank acc nothing happens. It does not paste. No, I don't get a cryptic code pasted, just NOTHING.
zzxc: what if you paste into MS Word instead?
seegal: haven't tried that, the formatting most likely would be lost. Tried that with an other Exc el spreadsheet- it lost all the formating and pasted as continous text.
== This happened ==
Every time Firefox opened
== Pls. see copy of the chat above. THIS A MAC OS X. In older versions, prior to 3.0 I could copy from CSV file on the website Ibank acc) and paste directly to my Excel spreadheet to reconcile my account.

How do I import the data from Excel (.xls) file into Oracle Database table

I have an excel file with 5 columns of 5000 rows.
I have to import 5000 rows of data into my oracle table with
same column names & Data types.
What is the best advise for this ?
Thanks.
Srini

You can connect to Oracle from Excel directly. I know you can read data but am not sure if you can export data.
Other option is to import the data into Access.
Create an ODBC connection for Oracle
Use the to connect to Oracle from Access
Export data to Oracle from Access

Load / Update Table from a .csv file

Hi All,
I thought I would just throw this out there..be kind.
I have a requirement to build a page that allows the user to upload a excel (well I'll have them save it as a .csv) and upate an existing table in their schema.
I have successfully created a similar page for inserting into an existing table however my update is not working. Then I realized what the Oracle Application Express Tool does that for me on, LOAD DATA page. The feature I like best is that after browsing for the file and clicking next it shows the column header and the row data underneath. I would really like to duplicate the functionality of this page.
I looked into the flows schema found related procedures , for example wwv_flow_load_excel_data,but I'm lost on how to use them.
Is there a way to duplicate the LOAD DATA Page and fit it to meet the users requirement?
Also I have included my coding attempt :

Thank You for your reply, I actually bookmark your site yesterday when googling this problem.
I am going to give it a try. I have ran through steps 1 through 4. Step 4 , I modified to my page.
Just a little more help..
do I put my update table code in the procedure (step 4) - how do I view and extract the information from the collection?

-- I looked in the ginodba schema (the ref schema for the app) for this collection but it's not there
cleanup;

SQL*Loader - How to load only a few columns from a .csv file to ora table

Could anyone please let me know how to load few columns from a .csv
file into a oracle table using SQL*Loader.
I know how to create a .dat and .ctl file and run the sql loader.
Suppose I have a .csv file with
col1, col2, col3, col4
and I only need to load col1 and col3 into col_a and col_b respectively
in table_a?
structure of table_ a
col_a,
col_b
Please advice

Try like..it i will work..

How to read/write .CSV file into CLOB column in a table of Oracle 10g

I have a requirement which is nothing but a table has two column
create table emp_data (empid number, report clob)
Here REPORT column is CLOB data type which used to load the data from the .csv file.
The requirement here is
1) How to load data from .CSV file into CLOB column along with empid using DBMS_lob utility
2) How to read report columns which should return all the columns present in the .CSV file (dynamically because every csv file may have different number of columns) along with the primariy key empid).
eg: empid report_field1 report_field2
1 x y
Any help would be appreciated.

If I understand you right, you want each row in your table to contain an emp_id and the complete text of a multi-record .csv file.
It's not clear how you relate emp_id to the appropriate file to be read. Is the emp_id stored in the csv file?
To read the file, you can use functions from [UTL_FILE|http://download.oracle.com/docs/cd/B19306_01/appdev.102/b14258/u_file.htm#BABGGEDF] (as long as the file is in a directory accessible to the Oracle server):
declare
    lt_report_clob CLOB;
    l_max_line_length integer := 1024;   -- set as high as the longest line in your file
    l_infile UTL_FILE.file_type;
    l_buffer varchar2(1024);
    l_emp_id report_table.emp_id%type := 123; -- not clear where emp_id comes from
    l_filename varchar2(200) := 'my_file_name.csv';   -- get this from somewhere
begin
   -- open the file; we assume an Oracle directory has already been created
    l_infile := utl_file.fopen('CSV_DIRECTORY', l_filename, 'r', l_max_line_length);
    -- initialise the empty clob
    dbms_lob.createtemporary(lt_report_clob, TRUE, DBMS_LOB.session);
    loop
      begin
         utl_file.get_line(l_infile, l_buffer);
         dbms_lob.append(lt_report_clob, l_buffer);
      exception
         when no_data_found then
             exit;
      end;
    end loop;
    insert into report_table (emp_id, report)
    values (l_emp_id, lt_report_clob);
    -- free the temporary lob
    dbms_lob.freetemporary(lt_report_clob);
   -- close the file
   UTL_FILE.fclose(l_infile);
end;This simple line-by-line approach is easy to understand, and gives you an opportunity (if you want) to take each line in the file and transform it (for example, you could transform it into a nested table, or into XML). However it can be rather slow if there are many records in the csv file - the lob_append operation is not particularly efficient. I was able to improve the efficiency by caching the lines in a VARCHAR2 up to a maximum cache size, and only then appending to the LOB - see [three posts on my blog|http://preferisco.blogspot.com/search/label/lob].
There is at least one other possibility:
- you could use [DBMS_LOB.loadclobfromfile|http://download.oracle.com/docs/cd/B19306_01/appdev.102/b14258/d_lob.htm#i998978]. I've not tried this before myself, but I think the procedure is described [here in the 9i docs|http://download.oracle.com/docs/cd/B10501_01/appdev.920/a96591/adl12bfl.htm#879711]. This is likely to be faster than UTL_FILE (because it is all happening in the underlying DBMS_LOB package, possibly in a native way).
That's all for now. I haven't yet answered your question on how to report data back out of the CLOB. I would like to know how you associate employees with files; what happens if there is > 1 file per employee, etc.

Script to import contacts from CSV file into Address Book

Hi,
I am wondering if it would be possible to import contacts from a CSV file into a group in Address Book using applescript, and if so, if anyone is aware of a script that does this or something similar.
I have a CSV file with three columns 'First Name', 'Last Name' and 'Email Address'. I would like these to correspond with 'First', 'Last' and (Work) 'Email' in Address Book.
Ideally the script would also check to see if entries already exist for the people being imported, but this is less crucial.
Thanks in advance for any assistance,
Nick

Hi,
Test this on a very small csv file (four or five contacts) to see if it works for you. It will not de-duplicate. You don't give the name of the group, so you'll need to replace Name of group in the second line with your group name, enclosed in double quotes.
--begin script
set the_people to read (choose file with prompt "Choose your CSV file")
set the_group to "Name of group"
set old_tids to AppleScript's text item delimiters
set AppleScript's text item delimiters to ","
set par_count to (count paragraphs in the_people)
repeat with x from 1 to par_count
          set next_par to paragraph x of the_people
          set first_name to text item 1 of next_par
          set last_name to text item 2 of next_par
          set e_mail to text item 3 of next_par
          tell application "Address Book"
                    set nu_person to make new person with properties {first name:first_name, last name:last_name}
make new email at end of emails of nu_person with properties {label:"Work", value:e_mail}
                    add nu_person to group the_group
save
          end tell
end repeat
set AppleScript's text item delimiters to old_tids
--end script
Watch out for bad line breaks in the lines beginning "set nu_person..." and "make new email..."
