Read table data and fetch file from path specified in table column

Hi,
I have a situation where file path information is stored in database table along with other columns - I need to read data from SQL Server table row by row, go to the path identified by the record, check for existance of the file - if the file is available copy it to a staging area, then read the next record. Repeat this process until the last record is fetched from the table. At the end, zip all the files found and FTP to a different location. If the file is not found in the path specified, write the database record to a seperate text file.
At end of the process, send an email with records for which files were not found at specified location.
Thanks

Hi,
That is not complex to solve at ODI.
Try the following.
1) Create a package
2) create a variable to receive the path as parameter and drag and drop it at package as "Declared"
3) drag and drop the ODI Tool "odiFileMove" using and let the variable as patch at ODI Tool parameter.
Use the parameters -ACTION=MOVE -TIMEOUT=100 and -NOFILE_ERROR=NO (take a look at ODI Toos Reference for other parameters)
3) Create a "KO" (error) flow to write the variable at a text file. That will allow the process knows what file is missing
4) generate a scenario of this package
5) create a procedure
6) at first step, put the query from SQL Server (set the Logical Schema to the right connection)
7) at Target tab, put the call to the scenario generated using the returned value from query parameter. Plus, let the -SYNC_MODE=1. That will call one scenario by time.
8) create a new step to zip the files at stage directory
9) create a step to make the ftp
10) create a step to mail the txt generated with files not founded. If you wish, you can make a validation on the file to see if is necessary to send the mail, it means, if there is any file missing.
Does it help you?

IPhoto reads wrong date of .mov file from iPhone 3GS...help!

Hi all
Need some help/advice please.
I have a bunch of files I am importing in to iPhoto that were initially downloaded to a windows laptop. I used Graphic Converter (GC) to successfully rotate and align the creation/modified dates so iPhoto reads the correct date. Now GC edits the .jpg and .avi file metadata fine, but wont edit .mov files from my iPhone? So now the iPhone videos are strewn all over the place in iPhoto compared to where they should be date-wise. Any ideas on how to fix this issue?
The .mov files in GC show the correct creation date, but iPhoto reads the actuals file's modified date instead of the internal creation date? So strange?
Thanks
Jared

iPhoto gets it's date and time from the Photos Exif metadata, not the file creation or modification dates. It will only use those if your photos have no Exif.
If you subsequently export these files then the created and modification dates a re very likely to change.
You can adjust the date and time rather more easily in iPhoto (Using either the Photos -> Adjust Date and Time and/or the Photos -> Batch Change commands) You can also write the corrected date and time to the Exif of the oriignals files, and export it along with the file in the future.
I'm not sure what's up with the dates on these mov files, but Movies don't have an Exif. You might want to check with the makers of Graphic Coverter for help.
You know that you can move pics and movies around inside iPhoto, right? Drag them from Event to Event?

How can I get data in flat file from Pool table and cluster table ?

Hi,
I am working in one Achiving project. My requirement is to get data into flat file from Cluster table and pool table.
Is there any tool avilable to download data into flat file from pool table and cluster table ?
if table name given in the selection screen then data will be downloaded into flat file.
waiting for quick response.
Best Regards,
Bansidhar

Data cannot be retrived directly form the cluster table
as the Cluster results are stored in Cluster Key say for example PCLkey
and form that Key we need to fetch the data
these clustes are not the part of PNP or PNPCE tables

How to know date and time information from Trace File defaultTrace.X.trc?

Hi, all.
i'm using EP 6.0 SP9 patch 1.
As you know, default trace is written in the <SID>\JC00\j2ee\cluster\server0\log\defaultTrace.X.trc.
By using the default trace formatter, it shows like the following sample messages.
#1.5#0011110E7B2000590000000100000A100003EC71562E6EBC#1104396451585#com.sap.jms.server.ServerClientAdapter##com.sap.jms.server.ServerClientAdapter#Guest#18####716257115a3f11d9b73b0011110e7b20#SAPEngine_Application_Thread[impl:3]_23##0#0#Error#1#/Applications/JMS#Plain###JMS internal error at ServerClientAdapter! JMS Service is not started!#
My questions are
1. how do we retrieve the date and time information from the above message? It seems that this message has date and time info because LogViewer shows the date and time based on the above message.
2. how do we change the above date format to easier one
like "YYYY:MM:DD:hh:mm:ss"? i know that it can be configured from the Visual Admin --> Services --> Log Configurator but i don't know the exact place for the trace file.
Thanks.

Hi Sejoon,
I use the standalone Logviewer to read the log files. Works great.
"If you have an SAP Web Application Server Java 6.20 or below you may also get a standalone_logviewer.zip file at the SAP Service Marketplace at service.sap.com/download → SAP NetWeaver → Release 04. In this case JDK version 1.3 or higher must be installed on the system. The java version must be same on the server and the client.
In the SAP Web AS Java 6.30 installation a folder named logviewer_standalone can be found under: <path Of J2EE installation>/<SysID>/JC<nr>/j2ee/admin/logviewer_standalone. Verify that the batch file logviewer.bat is installed in the directory logviewer-standalone.

Reading uknown DB *.dat and *.idx files

I'm trying to read the tables structure and data of a couple of *.dat and *.idx files. I don't know what DB are they created with - I tried diffrent db managers but noone recognized them. Some file examples are here (rar archive 304 kb): http://zorko.ru/_db2read.rar
Any help much appreciated.

well, you can't really tell what's database these files are for just by extension of filename. Oracle will take any file name extension that does not violate the rule.
the wild guess is .dat is datafiles of tablespace holding data and .idx is datafiles of tablespaces holding indexes.
However if they do for Oracle database you can't read out meaning information from them without properly setup the database. To do that you will need more information.
try to use "strings" to read the file on unix platform, see if you can get anything ring the bell.

How to read the date and time information of a file by labview

how to read the date and time information of a file by labview? for example, created time and modified time.
Solved!
Go to Solution.

if you need to know the last modification date of file:-
"Functions->File I/O->Advanced File Functions->File/Directory Info.vi"
This vi returns the value of file's last modification date. This is returned as U32 number. To see it in MM/DD/YY format you must create the indicator, right-click on it and select "Format & Precision" item from drop-down menu. Then select "Time and Date" format there.
Thanks as kudos only

Exporting table data into text files

I got a request to export the data from about 85 tables into 85 text files. I assume that they will want a header row and some delimiter character. This is a process that must run every night by a sql job.
Obviously I want it to be flexible. Tables could be addede and removed and columns could be added and removed. There will probably be a control table that has the list of tables to export.
Looked at bcp - but seems that it is command line only?
SSIS package?
What other options are there?

Wanted to post my solution. Ended up using bcp in a PowerShell Script. I was unable to use bcp in SQL because it requires xp_cmdshell and that is not allowed at many of our client sites. So wrote a Powershell script that executes bcp. The ps script
loops through a table that contains a row for each table/view to export along with many values and switches for the table/view export: export path, include column headers, enclose each field in double quotes, double up embedded double quotes, how to format
dates, what to return for NULL integers - basically the stuff that is not flexible in bcp. To get this flexibility I created a SQL proc that takes these values as input and creates a view. Then the PS bcp does a SELECT on the view. Many of my tables are
very wide and bcp has a limit of 4000/8000. Some of my SELECT statements ended up being GT 35k in length. So using a view got around this size limitation.
Anyway, the view creation and bcp download is really fast. It can download about 4 gb of data in 20 minutes. It can download it faster the 7z can zip it.
Below is the SQL proc to format the SELECT statement to create the view for bcp (or some other utility like SQLCMD, Invoke-SQLCMD) or SQL query by "SELECT * from v_ExportData". the proc can be used from SQL or PS, or anything that can call a SQL
Proc and then read a SQL view.
IF EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N'[dbo].[ExportTablesCreateView]') AND type in (N'P', N'PC'))
DROP PROCEDURE [dbo].[ExportTablesCreateView]
GO
CREATE PROCEDURE [dbo].[ExportTablesCreateView]
ExportTablesCreateView
Description:
Read in a tablename or viewname with parameters and create a view v_ExportTable of the
data. The view will typically be read by bcp to download SQL table data to flat files.
bcp does not have the options to include column headers, include fields in double quotes,
format dates or use '0' for integer NULLS. Also, bcp has a limit of varhar 4000 and
wider tables could not be directly called by bcp. So create the v_ExportTable and have
bcp SELECT v_ExportTable instead of the original table or view.
Parameters:
@pTableName VARCHAR(128) - table or view to create v_ExportTable from
@pColumnHeader INT =1 - include column headers in the first row
@pDoubleQuoteFields INT = 1 - put double quotes " around all column values including column headers
@pDouble_EmbeddedDoubleQuotes INT = 1 - This is usually used with @pDoubleQuoteFields INT = 1. 'ab"c"d would be 'ab""c""d.
@pNumNULLValue VARCHAR(1) = '0' - NULL number data types will export this value instead of bcp default of ''
@pDateTimeFormat INT = 121 - DateTime data types will use this format value
Example:
EXEC ExportTablesCreateView 'custname', 1, 1, 1, '0', 121
@pTableName VARCHAR(128),
@pColumnHeader INT = 1,
@pDoubleQuoteFields INT = 1,

Help Fetching files from an FTP server into a DBase or local folder

Hello Gurus!
I need help to automate or design/write an app capable of (replace a manual process) reading log files in an ftp server folder, this log files are called CDR (Call Detail Record) and named as follow cdr.txt.20020221010000 meaning that this log file was created on 2002/02/21 at 01:00:00.
This CDR log files are generated every hour by a Lucent telephone switch using a software/program called EXS ExchangePlus in ASCII format (fixed length delaminated, Char data type). EXS ExchangePlus writes a record in this CDR/log files after the call is completed, i.e. Calling_Number, Called_Number, Date_connect (yyyymmdd), Time_connect (hhmmss), Charged_time (hhmmss, duration of the call), and so on.
The manual process I am using now is:
1. Log in the ftp server into the folder where the CDRs log files are, located the latest generated CDRs log files and downloaded them into a local folder/directory. Normally I download the CDR for full day or 24 CDRs log files.
1a. Optionally sometimes I used a program called VEdit compiled/gather all 24 CDRs into a single file.
2. Once I have downloaded the CDRs I want to process (normally I process a full day 24 CDRs) I imported then into a Data Base temp table, where then I do the conversion of data types (i.e. Dates and times fields from char type -> to ->Date type) and calculations for billing purposes.
So if somebody can help with this, I would really appreciated ideas or any kind of information on how to automated this process.
I�m familiar with Java2 platform (using JDeveloper ) so if somebody has done something like this before using java, this would very helpful. Or Maybe using Visual Basic 6.0 would help too.
Thanks Gurus, and I look forward to hear from you soon!
Alf Pathros!

Thanks for the idea, even though an example would help me more.
I already found the FTPClient class.
I also would like to knwo if there is a away Ican append/merged various files CDRs into a single/one to then dump/import it into the database

This may not be an option for you but in pinch you may want to consider outputing your data to an MS Spreadsheet, then saving it as a CSV. It's somewhat of a cumbersome process, but it will get you by for now.
You will need to change your content type to application/vnd.ms-excel.

How to download a file from Path specifed

Hi Frndz..
How to download a file from a specified path like , i have a file on server in the path like "C://temp/Sap.pdf"
I want to download this to user desktop..
Thanks in Advance

Rajesh

Hi,
For file down load u have to use a UI element as "File download".
u just create context attribute as setdownload_res and file data.
setdownload_res as of type "com.sap.ide.webdynpro.uielementdefinitions.Resource" then bound it to the ui element "resource".
file data as of type "com.sap.tc.webdynpro.progmodel.api.IWDInputStream"
and set calcuclated as true and read only as true.
then in doinit method u just write this code
IWDAttributePointer attr = wdContext.currentContextElement().getAttributePointer("fileData");
IWDResource res = WDResourceFactory.createResource(attr,null,WDWebResourceType.UNKNOWN);
wdContext.currentContextElement().setDownload_res(res);
wdComponentAPI.getMessageManager().reportSuccess(""+c);

stream = WDResourceFactory.createInputStream(new FileInputStream(new File("<pathof the file to be download>")));
catch(Exception e)
e.printStackTrace();
return stream;
