From last couples of weeks i am trying to load my CSV file into HANA Table, but i am unable to succeed.
I am getting error "Cannot open Control file, /dropbox/P1005343/CRM_OBJ_ID.CTL". I have followed each and every step in SDN, still I could not load data into my HANA table.
FTP: /dropbox/P1005343
SQL Command:

Hi All,
I have successfully loaded the file into HANA database in folder P443348 but while importing file, I am getting the following error message such as
SAP DBTECH JDBC: [2] (at 13) : general error: Cannot open Control file, "/P443348/shop_facts.ctl"
This is happening while I am executing the following import statement

I have tried several options including changing the permissions of the folders and files to no success. As of now my folder has full access, which is 777
Any help would be greatly appreciated so that I can proceed further

How to load CSV files into HANA

1.- Create an CSV file with your data
2.- Copy the file to dropbox/yourname inside the HANA box
3.- Create a table in HANA with the structure of your file
4.- create the control file BBB with the following information:
import data
into table XXX."YYY"
from 'ZZZ.csv'
record delimited by '\n'
fields delimited by ','
optionally enclosed by '"'
error log 'Text_Tables.err'
Where XXX is your schema, YYY is your HANA Table and ZZZ is your file
5.- Open an Script File and write the following:
LOAD FROM '/filer/dropbox/yourname/BBB.ctl';
where BBB is the name of your control file
Greetings,
Blag.

With the recent upgrade to the HANA SP3...the method to upload files to HANA has been slightly changed...so here's the updated tutorial:
1.- Create an CSV file with your data
2.- Copy the file to the HANA Dev Center
3.- Open a FTP connection to ftp.sapdevcenter.com
(You can find the user name and password by doing a select to SYSTEM.FTP_SERVER)
and....*Don't paste the Username or password here or any other place!*
4.- Create a folder with your name on the FTP site and copy the file there
4.- Create a table in HANA with the structure of your file
5.- create the control file BBB with the following information:
import data
into table XXX."YYY"
from 'ZZZ.csv'
record delimited by '\n'
fields delimited by ','
optionally enclosed by '"'
error log 'Text_Tables.err'
Where XXX is your schema, YYY is your HANA Table and ZZZ is your file
5.- Open an Script File and write the following:
IMPORT FROM '/dropbox/yourname/BBB.ctl';
where BBB is the name of your control file
I just test it and it works...if it doesn't work for you, please let me know
Greetings,
Blag.

I have tried your changes but its not working. One more question is that I am having one column which contains commas, when I tried to load the file its failing. I think its the problem with commas.

Hi,
Using GUI_upload convert file to internal table data.
Using the below statement separate header and data from CSV.
Read t_itab into wa_titab index 1.
delete t_itab from wa_itab.
Create an internal table with the structure same as 'CSV' file and use the below statement to separate.
loop at t_itab into wa_itab.
      split wa_itab-rec at ',' into var1 var2 var3.
      wa_output-v1 = var1.
      wa_output-v2 = var2.
      wa_output-v3 = var3.
    append wa_output to t_output.
endloop.

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.
HTH

Hi
Ignore "SQL*Loader-292: ROWS parameter ignored when an XML, LOB or VARRAY column is loaded" error
after importing your csv file just change length CHAR(100000).
ex: your column col1 CHAR(1000) to change CHAR(100000).
and deploy your mapping and execute

Loading data from .csv file into existing table

Hi,
I have taken a look at several threads which talk about loading data from .csv file into existing /new table. Also checked out Vikas's application regarding the same. I am trying to explain my requirement with an example.
I have a .csv file and I want the data to be loaded into an existing table. The timesheet table columns are -
timesheet_entry_id,time_worked,timesheet_date,project_key .
The csv columns are :
project,utilization,project_key,timesheet_category,employee,timesheet_date , hours_worked etc.
What I needed to know is that before the csv data is loaded into the timesheet table is there any way of validating the project key ( which is the primary key of the projects table) with the projects table . I need to perform similar validations with other columns like customer_id from customers table. Basically the loading should be done after validating if the data exists in the parent table. Has anyone done this kind of loading through the APEX utility-data load.Or is there another method of accomplishing the same.
Does Vikas's application do what the utility does ( i am assuming that the code being from 2005 the utility was not incorporated in APEX at that time). Any helpful advise is greatly appreciated.
Thanks,
Anjali

Hi Anjali,

Combine multiple CSV files into a single multi-column CSV file

Hey Scripting Guy!
I have what is probably a simple issue, but I haven't been able to find the right answer.
I have 18 CSV files that each contain the same header and a single value as shown below:
"Sum"
"90"
These files are the results of SMTP traffic by domain.
All I want to do is to combine the 18 CSV files into a single file with the content of each file in a separate column, using the file name as the column header.
For example:
file1.csv
"Sum"
"90"
file2.csv
"Sum"
"325"
file2.csv
"Sum"
"3534"
The desired ouput is:
"file1.csv","file2.csv","file3.csv"
"Sum","Sum","Sum"
"90","325","3534"
I don't need to row of Sum's if it is easy to leave out. It would be even better if this could be put into an Excel spreadsheet.
Thanks for your help!

Can you post your script?
If you are not a technician and do not want to write a script then you should try hiring a consultant.
If you want to learn how to write a script then start here:

By the way...your request makes no logical or technical sense. What is the point of doing this? There is no relationship between these files.

How do I call two csv files into ews?

I have to call two csv files into a script with ews:
Param([string]$calInputFile = "C:\Algemene agenda\Data docenten.txt" )
Param([string]$calMailboxFile ="C:\Algemene agenda\Alle docenten.txt"
# Load all Entries
$calagenda = Import-Csv $calInputFile
$calMailbox = Import-Csv $callMailboxfile
This do not work.
How can I do this???

OH!! Why didn't I see this before? s-: You are having problems with the Param definition, but it appears you are having troubles pulling the data into the script. You can only have a single Param definition for a script. Try
the following instead:
Param(
[string]$calInputFile
= "C:\Algemene agenda\Data docenten.txt",
[string]$calMailboxFile
="C:\Algemene agenda\Alle docenten.txt"
## Load all Entries
$calagenda = Import-Csv $calInputFile
$calMailbox = Import-Csv $callMailboxfile
To define multiple parameters, you have your Param definition (with its parentheses) and all parameters are defined inside it, separated by commas.

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,

Thank you so much in advance,

Hola Anjali,
First of all, thank you for your quick answer.
I don´t think that there is anything missing in the CSV file. We are using SPP and also have the SCM 5.0. See if we load the file into SPP neither the order quantity, nor is the file in the "manual adjustment of raw data" is shown . What do u mean by downloading and uploading?
Thank you,
Almi
