Create a csv file and send it in an email

In coldfusion, is it possible to create a csv file and send it in an email, without ever saving that file on the hard drive?

Yes, you can create an email attachment without writing a file to disk. This feature was introduced in CF 8.0.1.
I've posted a sample to a previous thread on the forums.

See the CFMAILPARAM section of CF 8.0.1 release notes for attachments without a file on disk.

Help! Want to read from a xl file and get an output voltage value!!!

Hello..
I`m a beginner, so please help..
My program should output an voltage value that is read from an xl-file with one collum. The most important is that each values in the xl graph should be read per iteration. So that the file is read over time. I want to use this xl file to controll the output signal over time.
Can anyone show me how this VI would look like, and what would the xl file look like??

The easiest way to do this is to save your Excel file as a comma or tab separated text file and not the native Excel format. Then you can use Read From Spreadsheet File (on the File I/O palette). Using this, you can read the file all at once and then just have a 1D array that you can wire to a while or for loop so that with each iteration of the loop, you get one element in the array. A for loop automatically indexes an input array. Reading the file all at once will be more effecient that reading the file line by line.

Hello,
we have the following requirement.
We created an eventhandler.
Inside this eventhandler we built up an internal table with 1-n entries.
Now we want to create a csv-file or excel-file in background and send it to the users mailadress.
Are there standard function modules which we can use for this requirement.
We can´t download the file directly to the users client with cl_gui_frontend_services because we are not in SAP GUI but in CRM Webclient UI.
Thank you

Reading a Blob (CSV file) and displaying the contents

Hello Experts,
I’m currently working on a system that allows the users to upload an Excel spreadsheet (.xls) in the system. The upload page is a PL/SQL cartridge. Then I’ve written a Java servlet (using Oracle Clean Content) to convert the XLS into a CSV and store it back in the database. (it is stored in the “uploaded_files” table as a blob). I’m trying to create another procedure to read the contents of the blob and display a preview of the data on the screen (using an html table (will be done using cartridge)). After the preview, the user can choose to submit the data into the database into the “detail_records” table or simply discard everything.
Can anyone provide me any guidelines and/or code samples for reading the contents of a blob and displaying it as an html table? My data contains about 10 rows and 20 columns in the spreadsheet. I’ve been looking into using associative arrays or nested tables but I’m getting confused about how to implement them in my situation.
Any help is greatly appreciated.

BluShadow,
Thanks for your response. The reason that it is a blob is that we use the same table for uploaded files for several applications. Some files are text, some excel, some other formats. Hence the table has been set up in a generic sense.
However, in my procedure, I'm using
DBMS_LOB.createtemporary and
DBMS_LOB.converttoclob
Is there any way you could possibly provide an example of how to read the contents of the file?

Want to Read the a txt file and put the data into the table colums.

Database table:
first_name ,last_name,address,phone_number

Thanks For your help in advance.

How to read an IDOC flat file and send it to XI

Hi,
I'm looking for a way to read a complicated Idoc structured flat file sent to XI by a legacy system and then pushing that data to and R/3 system. Can anyone recommend a good technique?
Thanks,
Steeve

hi steven....
this shud help u...
for FileXIIDoc
File->XI->IDOC (how to start?)
also check this blog for specifying adapter specific identifiers in this scenario
These are steps to follow:
STEPS IN DESIGN
1. Import idoc from the SAP System (SAP02) through imported objects.
2. Create Data Type, Message Type, Message Interface for the Outbound File.
3. Create Message Mapping with file Message and idoc (Matmas04)
5.Create Interface mapping between File Interface and the idoc.
Steps to be followed in Creation of Technical and Business System
Technical System
In SLD, click on technical landscape->New Technical System->WebAS ABAP.
Business System.
1.Goto Business Landscape->New Business System->Name the business system.
2. Choose the technical system that needs to be attached->WebAS ABAP->Technical System Name.
Preconfiguration steps for transfer of data to IDOCS
1.Create a RFC Destination in SM59 of XI Server of type.
2.In transaction IDX1 ,create a port for the client of XI server.
3. The port has to be displayed in the idx2 transaction and we should be able to view the idocs which we imported through integration repository.
Steps in Configuration
1. Goto service without party, right click->Assign a business system.
2. Choose the business system to be added.
3. Create a File Sender Service with communication channel for the same.
4. Create an idoc receiver channel under the business system. Mention the RFC Destination and the port created for the same.
5. Mention the logical Name in the Service->Adapter Specific Parameters of both the File Sender Service as well as the business system.
6. Make the Sender Agreement for theFile Sender with communication channel.
7.Create the Receiver Determination and Interface Determination for the business system.
8.Create the Receiver Agreement for the Business system.
TCODES for File>XI>IDoc
SM59-rfc destination on recving side
IDX1-port on recving side
IDX2-load metadata

Is there a way to select a certain box of elements from a csv file and read that into LabVIEW?

Hello all, I was wondering if there was a way to select only a certain "box" of elements from a .csv file in LabVIEW? I have LabVIEW 2011 and my main goal is to take two arrays and graph them against each other. I can import the .csv file just fine and separate each row and each column to be its own, but say I have an 8X8 but want to graph the middle 4X5 or something like that. Is there any way to extract an array without starting at the beginning and without ending at the end? Thank you in advance.
Solved!
Go to Solution.

Hi Szklanam,
as a CSV file is just a TXT file with a different suffix you can read a certain number of lines of that file. So you can limit the number of rows in your resultung array. To limit the number of columns you still have to use ArraySubset, so maybe it's a lot easier to read the full CSV file and pick the interesting spots with ArraySubset...

Read from csv file and plot particular columns

Hello,
I`m a new user of Labview and here it comes...my first major problem.
Maybe this has been discussed before. I’ve made a search to solve my problem first but I couldn`t find anything helpful so I `ve decided to post a new message.
So here is my problem:
I`m working in a small semiconductor lab where different types of nitrides are grown using proprietary reactor. The goal is to read the collected csv files from each growth in Labview and plot the acquired data in appropriate graphs.
I have a bunch of csv files and I have to make a Labview program to read them.
The first part of my project I`ve decided to be displaying the csv file (growth log file) under labview (which I think works fine).
The second one is to be able to plot particular columns from the recipe in graphs in Labview (that one actually gives me a lot of trouble):
1. Timestamp vs Temperature /columns B and D/
2. Timestamp vs Gas flow /columns L to S/
3. Timestamp vs Pressure /columns E,K,T,U,V/
I`ve got one more problem. How can I convert the Timestamp shown in csv file to human readable date in labview? This actually is a big problem, because the timestamp is my x axis and I want to know at what time a particular process took place and I also want to be able to see the converted timestamp when displaying csv file at first. I`ve read a lot about time stamping in excel and timestamp in labview but I`m still confused how to convert it in my case.
I don`t have problems displaying csv file under Labview. My problems are with the timestamp and the graphs.
Sorry for my awful English. I hope you can understand my problems since English is not my mother language.
Please find the attached files.
If you have any ideas or suggestions I`ll be more than happy to discuss them.
Thank you in advance.
Have a nice day!

SSIS 2008 – Read roughly 50 CSV files from a folder, create SQL table from them dynamically, and dump data.

Hello everyone,
I’ve been assigned one requirement wherein I would like to read around 50 CSV files from a specified folder.
In step 1 I would like to create schema for this files, meaning take the CSV file one by one and create SQL table for it, if it does not exist at destination.
In step 2 I would like to append the data of these 50 CSV files into respective table.
In step 3 I would like to purge data older than a given date.
Please note, the data in these CSV files would be very bulky, I would like to know the best way to insert bulky data into SQL table.
Also, in some of the CSV files, there will be 4 rows at the top of the file which have the header details/header rows.
According to my knowledge I would be asked to implement this on SSIS 2008 but I’m not 100% sure for it.
So, please feel free to provide multiple approaches if we can achieve these requirements elegantly in newer versions like SSIS 2012.
Any help would be much appreciated.
Thanks,
Ankit

Hello Harry and Aamir,
Thank you for the responses.
@Aamir, thank you for sharing the link, yes I'm going to use Script task to read header columns of CSV files, preparing one SSIS variable which will be having SQL script to create the required table with if exists condition inside script task itself.
I will be having "Execute SQL task" following the script task. And this will create the actual table for a CSV.
Both these components will be inside a for each loop container and execute all 50 CSV files one by one.
Some points to be clarified,
1. In the bunch of these 50 CSV files there will be some exception for which we first need to purge the tables and then insert the data. Meaning for 2 files out of 50, we need to first clean the tables and then perform data insert, while for the rest 48
files, they should be appended on daily basis.
Can you please advise what is the best way to achieve this requirement? Where should we configure such exceptional cases for the package?
2. For some of the CSV files we would be having more than one file with the same name. Like out of 50 the 2nd file is divided into 10 different CSV files. so in total we're having 60 files wherein the 10 out of 60 have repeated file names. How can we manage
this criteria within the same loop, do we need to do one more for each looping inside the parent one, what is the best way to achieve this requirement?
3. There will be another package, which will be used to purge data for the SQL tables. Meaning unlike the above package, this package will not run on daily basis. At some point we would like these 50 tables to be purged with older than criteria, say remove
data older than 1st Jan 2015. what is the best way to achieve this requirement?
Please know, I'm very new in SSIS world and would like to develop these packages for client using best package development practices.
Any help would be greatly appreciated.

How can you identify these files? Is it based on file name or are there some info in the file which indicates
that it required a purge? If yes you can pick this information during file name or file data parsing step and set a boolean variable. Then in control flow have a conditional precedence constraint which will check the boolean variable and if set it will execute
a execte sql task to do the purge (you can use TRUNCATE TABLE or DELETE FROM TableName statements)
2. For some of the CSV files we would be having more than one file with the same name. Like out of 50 the 2nd file is divided into 10 different CSV files. so in total we're having 60 files wherein the 10 out of 60 have

The best way to achieve this is to append a sequential value to filename (may be timestamp) and then process
them in sequence. This can be done prior to main loop so that you can use same loop to process these duplicate filenames also. The best thing would be to use file creation date attribute value so that it gets processed in the right sequence. You can use a
script task to get this for each file as below
http://microsoft-ssis.blogspot.com/2011/03/get-file-properties-with-ssis.html
3. There will be another package, which will be used to purge data for the SQL tables. Meaning unlike the above package, this package will not run on daily basis. At some point we would like these 50 tables to be purged
with older than criteria, say remove data older than 1st Jan 2015. what is the best way to achieve this requirement?
You can use a SQL script for this. Just call a sql procedure
with a single parameter called @Date and then write logic like below
CREATE PROC PurgeTableData
@CutOffDate datetime
AS
DELETE FROM Table1 WHERE DateField < @CutOffDate;
DELETE FROM Table2 WHERE DateField < @CutOffDate;
DELETE FROM Table3 WHERE DateField < @CutOffDate;
GO
@CutOffDate which denote date from which older data have to be purged
You can then schedule this SP in a sql agent job to get executed based on your required frequency

How to read the entire CSV file content

Hi All,
I am using JDBC adapter and i need to send the entire CSV file to the Blob datatype filed.
How to achive this?
Thanks
Mahi.

Hi Mahi
So you want to send the content of the entire CSV file to a particular field in data base?
You can write a java mapping to read the content of the CSV file and then populate the same under the field of the data base.
If you need help on java mapping then please provide the sample CSV file and the target JDBC structure.

I just want to read in a csv file and send it to an instrument at 1 Hz per line
