Delete and update contents in a CSV File

Hi All,
I am new to java . I am able to read the records from CSV file using BufferedReader and I am getting output like this
"100,a100,1b100" -->1st record
"200,b200,dc300" -->2nd record
"400,f344,ce888" -->3rd record.
Now I need some help in below requirements.
1.How to delete a specfic record?
2.If record already exists how to update the existing record with new values?
Please share your ideas or give me some code snippet..
Thanks in Advance

Or if each record is the same length and you are not inserting -
just modifying values in existing ones - you can use a
RandomAccess file.

How to delete contents of a csv file except header using powershell

Hi,
I am trying to delete all the content of my csv file except its header. currently I am using clear-content but using this headers are also getting deleted. Basically I need a command which deletes all the rows of a csv file except first row.Please help.

I'm only going to respond to prove that the useless troll is useless and wrong.
Perhaps someday the troll will finally realize that it is worthless and will go away. No one cares about what it has to say and no one has ever found it to be helpful. Even good information is bad information when it is presented in an insulting, blathering,
incoherent, and belittling tone. Plus, I think it's really funny when something tries to justify its own sad existence by making itself feel superior (when it clearly isn't). Sometimes I almost feel bad for it, but then it reminds me of how big of a jerk it
really is.
Get a life, get some friends, just go do something that isn't totally worthless (yeah, I know, you can't..).

How to make the result showing one time and make the result to csv file?

My script having problem of showing out all the AD computer name result from Active Directory once when running it and storing the result to csv file. I am a newbie in AD and powershell.
This is the code:
$strADPathFile = "D:\Powershell for AD\ADPathList.txt"
$strErrLogFile = "D:\powershell for AD\errorADComputer.log"
$arrADPath = Get-Content -Path $strADPathFile
foreach ($strADPath in $arrADPath)
try
$objSearch = New-Object DirectoryServices.DirectorySearcher
$objSearch.Filter = '(objectCategory=computer)'
$objSearch.SearchRoot = $strADPath
$objSearch.SearchScope = "Subtree"
$objSearch.PageSize = 1000
$objResults = $objSearch.Findall()
write-host "Retrieving AD computer information in the domain $strDomain"
write-host "Number of AD Computer Name result: "$objResults.Count
foreach($objResult in $objResults){
$objComputer = $objResult.GetDirectoryEntry()
write-host $objComputer.dNSHostName
try
# InsertSQLTable $objComputer
catch
write-host $error[0]
$strError = $objComputer.dNSHostName + " " + $dateNow + $error[0]
Add-Content $strErrLogFile $strError
catch
write-host $error[0]
Export-Csv D:\PowerShellforAD\test2.csv
This is the error that I had get is that it will get the result for 2nd time again.
By the way, what is InputObject about? I had research some of it and still did not quite get it. Can anyone explain? Thanks

Hi,
in the final line you call Export-Csv. which is a great command at exporting information. However, for it to work it needs a path to export to (D:\PowerShellforAD\test2.csv in your case) and Information (InputObject) to export.
You do not give that command any Information, so it throws an error.
Cheers,
Fred

Trying to Writing (update) New Entries into CSV files

Hello, I'm trying to write (update) entries to a csv file. I have been able to write to the csv file using the following code;
String stest1 = "hello2", stest2="no1";
          //Open Connection
          FileWriter fw = new FileWriter("c:/test2.csv", true);
          FileOutputStream fileOut = new FileOutputStream("c:/test2.csv");
          fw.write(stest1+",");
          fw.write(stest2 + ",");
          fw.write("\n");
          fw.flush();
          fw.close();
This overwrites the previous content with the new entries.
Does anyone know how I would be able to update the csv file?
Thanks

I need to monitor a transducer block parameter and save it to a CSV file.

How can I monitor a transducer block parameter and save it to a CSV file? The reason is that I need to do some long-term testing of an FFb device we are developing, and I need to read the primary output parameter of the transducer block (not the scheduled AI block) every second or two and save to a CSV file.
I have tried to figure out a way to do that with FBUS Configurator, unsuccessfully, and I purchased FBUS Monitor, as that was recommended by an industry expert, but I have been unsuccessful at getting that to work as well.

Hi Wpinson,
Neither FBUS Configurator nor Monitor can meet your requirement. However, there are other approaches. NI-FBUS provides APIs for C, LabVIEW, VB and C#. You can use these APIs to read a parameter value of any block and use standard file IO functions to save the date into CSV file. The LabVIEW APIs are highly recommended because they are easy-to-use and LabVIEW also provides APIs for CSV file operations. You can build the application w/ LabVIEW in a short time.
You can find the examples of the FBUS APIs in the following folders:
1. C: C:\Program Files\National Instruments\NI-FBUS\MS Visual C\examples
2. VB: C:\Program Files\National Instruments\NI-FBUS\MS Visual Basic\example
3. C#: C:\Program Files\National Instruments\NI-FBUS\MS .NET\examples\CsharpExample
4. LabVIEW: search "fieldbus" in the LabVIEW example finder.

What is the best, most efficient way to read a .xls File and create a pipe-delimited .csv File?

What is the best and most efficient way to read a .xls File and create a pipe-delimited .csv File?
Thanks in advance for your review and am hopeful for a reply.
ITBobbyP85

You should have no trouble doing this in SSIS. Simply add a data flow with connection managers to an existing .xls file (excel connection manager) and a new .csv file (flat file). Add a source to the xls and destination to the csv, and set the destination
csv parameter "delay validation" to true. Use an expression to define the name of the new .csv file.
In the flat file connection manager, set the column delimiter to the pipe character.

Deleting and updating records in a database table

dear all ,
i have created a databse table to which i have to update and delete records thru my program whixh i am unable to do so plz help me.

Hi Sonu,
To delete and update the records in your database table, you can create a Function Group and all the necessary function modules for it. This will a good approach as this will separate the database interface logic and the business logic. You need to use the DELETE and UPDATE ABAP keywords to delete and update the records of the database tables. Have a look at the ABAP Keyword documentation for a complete details of the usage.
Have a look at the following link:
DELETE
http://help.sap.com/saphelp_nw04/Helpdata/EN/fc/eb3aef358411d1829f0000e829fbfe/frameset.htm
UPDATE
http://help.sap.com/saphelp_nw04/Helpdata/EN/fc/eb3aef358411d1829f0000e829fbfe/frameset.htm
Hope this will help.

How can I delete and update records using where conditions?

I want to delete and update the coherence records with some conditions, I describe it to use SQL as follows:
delete from "contacts" where getStreet() = "dsada";
update contacts set getStreet() = "dddd" where getCity() = "ssss";
Can I use the filter like query to achieve this requirement as follows:
ValueExtractor::View vHomeStateExtractor = ChainedExtractor::create(
ChainedExtractor::createExtractors("getHomeAddress.getState"));
Object::View voStateName = String::create("MA");
Set::View setResults = hCache->entrySet(
EqualsFilter::create(vHomeStateExtractor, voStateName));
I know I can use get and put to achieve this requirement , but it Requires a two-interaction between the client and coherence server. Does it have And another way?
Thanks very much, and please Forgive my English is not very good.

Hi,
You have a couple of options for updating or deleting using a Filter.
For deleting you can use an Entry Processor and the cache invokeAll method. Using "out of the box" Coherence you can use the ConditionalRemove entry processor. I'm a Java person so the C++ below might not be exactly right but you should get the idea.
ValueExtractor::View vHomeStateExtractor = ChainedExtractor::create(
ChainedExtractor::createExtractors("getHomeAddress.getState"));
Object::View voStateName = String::create("MA");
hCache->invokeAll(EqualsFilter::create(vHomeStateExtractor, voStateName),
ConditionalRemove::create(AlwaysFilter.getInstance());For update you would either need to write custom Entry Processor implementations that perform the updates you require or you can use out of the box POF or Reflection ValueUpdaters that update specific fields of the entries in the cache. These valueUpdaters would be wrapped in an UpdaterProcessor so the call would be very similar to the code above.

VBScript to read the content of a .csv file and delete old files mentioned in the .csv

I have a Windows 2003 file server.
I have generated a report in .csv format, about the files which are older than 1 year.
I need a VBScript to read the .csv file and delete the files which are enlisted there.
Can someone please help me with this?

Look into the "Learn" link above. There are resources and instructions on how to write VBScript code. Look into how to use the FileSystemObject.

Search and Delete a specific record from a CSV file

Hi All,
I am new to java . I want to search for the records from CSV file and delete the row form the file.
Below is my Sample .csv
100||a100||1b100
200||b200||dc300
200||bg430||ef850
400||f344||ce888
Now I need some help in below requirements.
1.How to delete a record having value 200 and b200?
2.If record already exists how to update the existing record with new values?
Please share your ideas or give me some code snippet..
Thanks in Advance

In that case Do i need to write the entire contents of my file to a hash table(sumthng like this) and modify the Second row in my case with the new values..
is it possible??I would have done like this (though there maybe better methods)
1- create a class representing the record.
class Record{
      String field1;
      String field2;
      String field3;
      // and so on....
      //setters
      public void setFeild1(String str){
          field1=str;
      // and so on....
      //getters
      public String getFeild1(){
          field1=str;
      // and so on....
      public String toString(){
           return(field1+"||"+field2+"||"+field3);
}//end class2- then create an ArrayList meant to have objects of this class (Generics).
3- read from the file , create a new Record Object and add that to the ArrayList
4- perform operations on the ArrayList (you can add new records, and delete record, update......)
5- write the record back to file using 'toString()' method.
is there ne sample code available for thisdon't know, but you rarely get full code on forums.....outline given can be followed
Thanks!
Edit: It appears that 'r035198x' and me have the same point. This shows that this methodology is almost a standard way( if we ignore the Random access files.....)

LOOP AT itab.
CLEAR idat.
SPLIT itab-rec AT ',' INTO idat-aaaa
idat-bbbb ,
idat-asdc ,
idat-dfgfhg ,
idat-sdfsg ,
idat-sdf ,
idat-sdf ,
idat-sdf ,
idat-dfg   ,
idat-sdf    ,
idat-sgf ,
idat-drgftfgh ,
idat-sgf ,
idat-drgtf ,
idat-swftgd ,
idat-sgf ,
APPEND idat.
ENDLOOP.
Now the issue is when I use the statement SPLIT itab-rec AT ',' this is not updating the table idat properly.Because the flat file contains the value as 'dkjffdj ,', too.
Can anyone give me some solution to update the internal table.

or you delete ' from csv file before uploading it or after uploading it, in this last case u can use statament replace:
REPLACE ''' WITH SPACE INTO ITAB-FIELD.
