Exporting a view to a flat file

Hi all,
Running Oracle 9i on Windows.
We have a stored procedure which runs a number of packages and populates a view called v$logmnr_contents.
We woudl like to export the contents of the view to a flat file so that it can be transferred over to another
server.
What options do we have for this? I've been reading about an Oracle package called utl_file, is this the
only option? I'm looking for whichever method is the most straightforward to implement.
Thanks in advance.
Dave

Hello Dave,
to dump data you can also use the SPOOL command in SQL*PLUS. The difference is that SQL*PLUS write to the client file system while utl_file writes to the server.

Export table data in a flat file without using FL

Hi,
I am looking for options where I can export table data into a flat file without using FL(File Layout) i.e., by using App Engine only.
Please share your experience if you did anything as this
Thanks

A simple way to export any record (table/view) to an csv fiel, is to create a rowset and loop through all record fields, like below example code
Local Rowset &RS;
Local Record &Rec;
Local File &MYFILE;
Local string &FileName, &strRecName, &Line, &Seperator, &Value;
Local number &numRow, &numField;
&FileName = "c:\temp\test.csv";
&strRecName = "PSOPRDEFN";
&Seperator = ";";
&RS = CreateRowset(@("Record." | &strRecName));
&RS.Fill();
&MYFILE = GetFile(&FileName, "W", %FilePath_Absolute);
If &MYFILE.IsOpen Then
   For &numRow = 1 To &RS.ActiveRowCount
      &Rec = &RS(&numRow).GetRecord(@("RECORD." | &strRecName));
      For &numField = 1 To &Rec.FieldCount
         &Value = String(&Rec.GetField(&numField).Value);
         If &numField = 1 Then
            &Line = &Value;
         Else
            &Line = &Line | &Seperator | &Value;
         End-If;
      End-For;
      &MYFILE.WriteLine(&Line);
   End-For;
End-If;
&MYFILE.Close(); You can of course create an application class for generic calling this piece of code.
Hope it helps.
Note:
Do not come complaining to me on performance issues ;)

Export multiple tables into one flat file

I have data in multiple tables on a processing database that I need to move up to a production database. I want to export the data into a flat file, ftp it to the production server and have another job pick up the file and process it. I am looking for
design suggestions on how to get multiple tables into one flat file using SSIS?
Thank You.

Hey,
Without a bit more detail, as per Russels response, its difficult to give an exact recommendation.
Essentially, you would first add a data flow task to your control flow. Create a source per table, then direct the output of each into an union all task. The output from the union all task would then be directed to a flat file destination.
Within the union all task you can map the various input columns into the appropriate outputs.
If the sources are different, it would probably be easiest to add a derived column task in-between the source and the union all, adding columns as appropriate and setting a default value that can be easily identified later (again depending on your requirements).
Hope that helps,
Jamie

Export HRMS data to a flat file

Hi All!
Are there any ways of exporting employee related data to a flat file without using a client app (PeopleCode or Integration Broker), that is simply generate a CSV feed from UI?

You can Schedule a query and specify the output format as text. Note that when you select View Log/Trace in process monitor, you will see a file with a .csv extension. However, it will open by default in Excel, and even if you select Save instead of Open it will try to change the extension to .xls. You will have to change it back to .csv.

How to export data from DB to flat file with ODI?

Who can tell me how to do it with ODI?
Please give me a simple example or steps.
Thank you.

There are two ways
Either use IKM Sql to File Append

SSIS to Export data from SQL to flat file dynamically

Hi.
I hope somebody can help me out, I have a table like this:
Date, StoreNumber, ProductCode, SalesItem, SalesAmout, Inventory
09-10-2014,10,1,10,10,30
As you can see I have a Date field and my table has information from 2014 at daily basis, What I'm trying to do is to export the information of this table to flat files, creating one file pear each date, as a result I will have about 280 files (one per date)
I do not know if it is possible or not.
Thank you.

Hi Mike,
you can do it using one Execute SQL Task and a ForEach Loop variable driven.
1st the Execute SQL Task "figures out" how many iterations the loop would need. The SQL as follows would drive it:
SELECT DISTINCT [DATE] FROM MyTable;
and you get the dates placed into a package variable of type recordset for the [280] files.
And then you can operate on the recordset in the loop "shredding it" in a DFT with a source query dynamically driven by the date as "select a,b,c from mytable where date = '" + @[User::CurentDate] + "'" placing each
"date" into its own file even naming the file after the date using the current value of the package variable (ADO row concept).
See an example: http://www.sqlis.com/sqlis/post/Shredding-a-Recordset.aspx

Export SQL View to Flat File with UTF-8 Encoding

I've setup a package in SSIS to export a SQL view to a flat file and it's working fine. I now need to make that flat file UTF-8 encoded. The package executes but still shows the files as ANSI encoded.
My package consists of a Source (SQL View) -> Derived Column (casts the fields to DT_WSTR) -> Destination Flat File (Set to output UTF-8 file).
I don't get any errors to help me troubleshoot further. I'm running SQL Server 2005 SP2.

Unless there is a Byte-Order-Marker (BOM - hex file prefix: EF BB BF) at the beginning of the file, and unless your data contains non-ASCII characters, I'm unsure there is a technical difference in the files, Paul.
That is, even if the file is "encoded" UTF-8, if your data is only ASCII values (decimal values 0-127, hex 00-7F), UTF-8 doesn't really serve a purpose over ANSI encoding. Now if you're looking for UTF-8 with specifically the BOM included, and your data is all standard ASCII, the Flat File Connection Manager can't do that, it seems.
What the flat file connection manager is doing correctly though, is encoding values that are over decimal 127/hex 7F in UTF-8 when the encoding of the connection manager is set to 65001 (UTF-8).
Example:
Input data built with a script component as a source (code at the bottom of this post) and with only one WSTR output column hooked to a flat file destination component:
a string containing only decimal value 225 (german Eszett character - ß)
Encoding set to ANSI 1252 looks like:
E1 0D 0A (which is the ANSI encoding of the decimal character value 225 (E1) and a CR-LF (0D 0A)
Encoding set to UTF-8 65001 looks like:
C3 A1 0D 0A (which is the UTF-8 encoding of the decimal character value 225 (C3 A1) and a CR-LF (0D 0A)
Note that for values over decimal 127, UTF-8 takes at least two bytes and up to four for the remaining values available.
So, I'm comfortable now, after sitting down and going through this, that the flat file connection manager is working correctly, unless you need a BOM.

How to create the Export Data and Import Data using flat file interface

Hi,
Request to let me know based on the requirement below on how to export and import data using flat file interface.....
Please provide the steps involved for the same.......
BW/BI - Recovery Process for SNP data.
For each SNP InfoProvider,
create:
1) Export Data:
1.a) Create an export data source, InfoPackage, comm structure, etc. necessary to create an ASCII fixed length flat file on the XI
ctnhsappdata\iface\SCPI063\Out folder for each SNP InfoProvider.
1.b) All fields in each InfoProvider should be exported and included in the flat file.
1.c) A process chain should be created for each InfoProvider with a start event.
1.d) If the file exists on the target drive it should be overwritten.
1.e) The exported data file name should include the InfoProvider technical name.
1.f) Include APO Planning Version, Date of Planning Run, APO Location, Calendar Year/Month, Material and BW Plant as selection criteria.
2) Import Data:
2.a) Create a flat file source system InfoPackage, comm structure, etc. necessary to import ASCII fixed length flat files from the XI
ctnhsappdata\iface\SCPI063\Out folder for each SNP InfoProvider.
2.b) All fields for each InfoProvider should be mapped and imported from the flat file.
2.c) A process chain should be created for each InfoProvider with a start event.
2.d) The file should be archived in the
ctnhsappdata\iface\SCPI063\Archive directory. Each file name should have the date appended in YYYYMMDD format. Each file should be deleted from the \Out directory after it is archived.
Thanks in advance.

Here's some info on working with plists:

They can be edited with any text editor. Xcode provides a graphical editor for them - make sure to use the .plist extension so Xcode will recognize it.

Problem with exporting to flat file

Hi all,
I have a dataset with many records. Each record has about 26,000 characters. I want to read the whole record into a table with a single field. So, I have a single field with CLOB datatype.
Now I want to export these records to a flat file. I tried spool on and spool off in SQL. But it prints on the first 84 or 85 characters of each record.
Can somebody tell me what is wrong ? Can somebody suggest a way to do this using expdp ?
I am working with Oracle Database 10g.
Someone please help, this has been going on since long...
Thanks a lot
sandeep

Thanks a lot for your reply Yoann. I tried what you've suggested and it worked.
But when the table was spooled, the record, after every 84 or 85 characters, gets printed on a new line.
Also, there is a separator "RECORD-----...." that gets printed every 8 or 10 lines. Can I also get rid of this in someway ?
Please excuse my silly questions, I'm very new to oracle.
Thanks and regards,
Sandeep

Export the Form Data to Excel File using FILE EXPORT

One problem i am getting...
I want to export printers page to some excel file using FILE > EXPORT option.
I login into System Administrator Responsibility > printers > register...
I want to export this printers data to flat file(EXCEL File) using FILE > EXPORT in the form...
The movement I click FILE > EXPORT...a flash screen appears and disapperas...nothing will be exported...
What Might be the problem...
How can I solve this...
My FND_LOBS_CTX index is fine..it is valid and

- Check the security level of the "Trusted sites" zone, make sure it is set to "Low"
- Make sure you do not have a yellow warning bar
- Make sure you are not accessing the application through dev60cgi/f60cgi
- Verify that you have sufficient space in the tablespace (Check init<SID>.ora for any errors)
- Check the export on some other modules to determine whether the issue is across all Apps or with a specific module only

Export data to flat file with no delimiter

Hi I've 3 columns in a view that i want to export to a flat file. I don't want the flat file to contain any delimiter such as commas , tabs etc..
I am using fixed width with the following setting
Header row delimiter {CR}-{LF}
Advance Options :
InputColumnwith 125
InputColumnwith 187
InputColumnwith 7
When i preview that data it looks correct , divided up into 3 columns
However when the data is exported to the flat file i get just one long string in the flat file on the first row.
What do i need to do to get the end of line characters to be identified
Thanks In advance

Column delimiter is here
Otherwise header row terminates a file line
