Loop through a csv file and return the number of rows in it?

What would be simplest way to loop through a csv file and
return the number of rows in it?
<cffile action="read" file="#filename#" output="#csvstr#"

<LOOP THROUGH AND COUNT ROWS>

ListLen(). Use chr(13) as your delimiter

Loading a CSV file and accessing the variables

Hi guys,
I'm new to AS3 and dealt with AS2 before (just getting the grasp when the change it).
Is it possible in AS3 to load an excel .csv file into Flash using the URLLoader (or ???) and the data as variables?
I can get the .csv to load and trace the values (cell1,cell2,cell3....) but I'm not sure how to collect the data and place it into variables.
Can I just create an array and access it like so.... myArray[0], myArray[1]? If so, I'm not sure why it's not working.
I must be on the completely wrong path. Here's what I have so far....
var loader:URLLoader = new URLLoader();
loader.dataFormat = URLLoaderDataFormat.VARIABLES;
loader.addEventListener(Event.COMPLETE, dataLoaded);
var request:URLRequest = new URLRequest("population.csv");
loader.load(request);
function dataLoaded(evt:Event):void {
var myData:Array = new Array(loader.data);
trace(myData[i]);
Thanks for any help,
Sky

just load your csv file and use the flash string methods to allocate those values to an array:
var myDate:Array = loader.data.split(",");

ENDIF.
Use OPEN DATASET in case if the file is on the application server..
After that USE SPLIT command at comma to get the contents of the 4th field...

I want to display the output as
HappyCodingXYZCollage
LearnC#XYXCollage
The below is the code I have tried so far.
// .Reading a CSV

Very simple example:
var column1 = new List<string>();
var column2 = new List<string>();
using (var rd = new StreamReader("filename.csv"))
while (!rd.EndOfStream)
var splits = rd.ReadLine().Split(';');
column1.Add(splits[0]);
column2.Add(splits[1]);
// print column1
Console.WriteLine("Column 1:");
foreach (var element in column1)
Console.WriteLine(element);
// print column2
Console.WriteLine("Column 2:");
foreach (var element in column2)
Console.WriteLine(element);

How do you return the number of Rows in a ResultSet??

How do you return the number of Rows in a ResultSet? It's easy enough to do in the SQL query using COUNT(*) but surely JDBC provides a method to return the number of rows.
The ResultSetMetaData interface provides a method for counting the number of columns but nothing for the rows.
Thanks

No good way before JDBC2.0. u can use JDBC2.0 CachedRowSet.size() to retrieve the number of rows got by a ResultSet.

Not certain this is what you're after, but this :
#import the contents of both csv files
$dbexcel=import-csv c:\dbexcel.csv
$liveexcel=import-csv C:\liveexcel.csv
#prepare the output csv and create the headers
$outputexcel="c:\outputexcel.csv"
$outputline="Name,Connection Status,Version,DbExcel,LiveExcel"
$outputline | out-file $outputexcel
#Loop through each record based on the number of records (assuming equal number in both files)
for ($i=0; $i -le $dbexcel.Length-1;$i++)
# Assign the yes / null values to equal the word equivalent
if ($dbexcel.isavail[$i] -eq "yes") {$dbavail="Available"} else {$dbavail="Unavailable"}
if ($liveexcel.isavail[$i] -eq "yes") {$liveavail="Available"} else {$liveavail="Unavailable"}
#create the live of csv content from the two input csv files
$outputline=$dbexcel.name[$i] + "," + $liveexcel.'connection status'[$i] + "," + $dbexcel.version[$i] + "," + $dbavail + "," + $liveavail
#output that line to the csv file
$outputline | out-file $outputexcel -Append
should do what you're looking for, or give you enough to edit it to your exact need.
I've assumed that the dbexcel.csv and liveexcel.csv files live in the root of c:\ for this, that they include the header information, and that the outputexcel.csv file will be saved to the same place (including headers).

Read two CSV files and remove the duplicate values within them.

Hi,
I want to read two CSV files(which contains more than 100 rows and 100 columns) and remove the duplicate values within that two files and merge all the unique values and display it as a single file.
Can anyone help me out.
Thanks in advance.

The first thing I think you should do is write a line-parser which splits your input data up into fields, and test it.
Then fill out the below parse method, and test it with that debugPrint method.
Then go to work on the print method.
I can help a bit along the way, but if you want to do this then you have to do it yourself. I'm not going to do it for you.

Webi report - save as .csv is bringing double the number of rows.

Hello all,
I am running a webi report and then saving it as .csv file to my desktop but when I save the file it is giving me double the number of rows. In my report I have employee, employee key, attributes and Org unit and some measures.
The .csv file has one additional column at the end which does not have any header and that column has "1" in the rows which should be legitimate and "0" in the rows which are so called duplicates, in these duplicate rows there is all data except it is missing the employee key and org unit key.
If I save as excel I get the right number of rows.
has any one seen this issue before?
Thanks in advance,

Exporting to csv is different from exporting to csv.
If you have any filter on your crosstab or table and you export it to excel it will show you your data according to this filter. Let's say in your table you have amount 0 and 1 and you filter that column so it will show only those records where amount = 1. If you export it to excel you'll get what you see in your WebI report, that's only records with amount = 1.
But if you export to csv the same Webi report with the same crosstab or table filtered by amount=1, the csv export will ignore this filter and your csv will include amount 0 and amount 1 records.
I don't know if that's a WebI's bug, but that's what has happened to me.
A workaround could be adding your filter directly in the query pane, not filtering your table columns.
Also check your query pane to see what object is bringing that extra column in your table.

Displayin message and fixing the number of rows in a table

Hi Experts,
I have a requirement like this
there is a table, where i need to diplay a message when there are no records and no rows should be visible on that table.
Also, when the records are populated from the context, i need to fix the number of rows in that table and display the records.
Please let me know hw this can be achieved.
Also in the table I have Link to URL, please let me know how to handle this reference, when i set the reference Property, its giving me an error stating that the file doesn't exist when the table gets loaded.
Thanks in Advance

Hi
Oh!! You should to explain it at first thread itself that you want to display a JPG imange or other WDWebResourceTypetaken form the backend.
1. So this is not at all a URL
2. You have to convert binary data to WDWebResource then display it in either Image UI element or other (like PDF , txt etc)
3
try
               //        Read the datasource of the FileUpload
               IWDResource res = wdContext.currentContextElement().getResource();
               InputStream in = res.read(false);
               ByteArrayOutputStream bOut = new ByteArrayOutputStream();
               int length;
               byte[] part = new byte[10 * 1024];
               while ((length = in.read(part)) != -1)
                    bOut.write(part, 0, length);
               in.close();
               bOut.close();
               IPrivateUploadCompView.IImageTableElement ele = wdContext.nodeImageTable().createImageTableElement();
               ele.setImage(wdContext.currentContextElement().getResource().getUrl(0));
               ele.setText(res.getResourceName());
               wdContext.nodeImageTable().addElement(ele);
          catch (Exception e)
               wdComponentAPI.getMessageManager().reportWarning(e.toString());
Here I assume that you convert that data to IWDResource type or
4.
WDWebResource.getWebResource(wdContext.currentContextElement().getresource(), type);
// getResource of type binary which u read from BAPI and set it in local context , type is MIMETYPE or hardcode it as "JPG"

Automator - Loop through a text file and process data through a 3rd party software

Just stumbled on Automator the other day (I am a mac n00b) and would like to automate the processing of a text file, line-by-line, using a third party tool. I would like Automator to loop through the text file one line at a time, copy the string and keep as a variable. Next, place the variable data (copied string) into the text field of the 3rd party software for processing. Once the processing is complete, I would like Automator to fetch the next line/string for processing. I see items like "copy from clipboard" and "variables" within the menu but I am not finding much documentation on how to utilizle this tool. Just hear how potentially powerful it is.
The 3rd party software is not a brand name, just something made for me to process text. I may have to use mouse clicks or tabs + [return] to navigate with Automator. A term I heard on Bn Walldie's itunes video series was "scriptable software" for which I don't think this 3rd party app would be.
Kind regards,
jw

Good news and bad news...
The good news is that it should be entirely possible to automate your workflow.
The bad news is that it will be a nightmare to implement via Automator, if it's even possible.
Automator is, essentially a pretty interface on top of AppleScript/Apple Events, and with the pretty interface comes a certain stranglehold on features. Knowing how to boil rice might make you a cook, but understanding flavor profiles and ingredient combinations can make you a chef, and it's the same with AppleScript and Automator. Automator's good at getting you from points A to B but if there are any bumps in the road (e.g. the application you're using isn't scriptable) then it falls apart.
What I'm getting at is that your requirements are pretty simple to implement in AppleScript because you can get 'under the hood' and do exactly what you want, as opposed to Automator's restricted interface.
The tricky part is that if no one else can see this app it's going to be hard to tell you what to do.
I can give you the basics on reading a file and iterating through the lines of text in it, and I can show you how to 'type' text in any given application, but it may be up to you to put the pieces together.
Here's one way of reading a file and working through each line of text:
-- ask the user for a file:
set theFile to (choose file)
-- read the file contents:
set theFileContents to (read file theFile)
-- break out the lines/paragraphs of text:
set theLines to paragraphs of theFileContents
-- now iterate through those lines, one by one:
repeat with eachLine in theLines
-- code to perform for eachLine goes here
end repeat
Once you have a line of text (eachLine in the above example) you can 'type' that into another application via something like:
tell application "AppName" to activate
tell application "System Events"
tell process "AppName"
keystroke eachLine
end tell
end tell
Here the AppleScript is activating the application and using System Events to emulate typing the contents of the eachLine variable into the process. Put this inside your repeat loop and you're almost there.

Stage tab delimited CSV file and load the data into a different table

Hi,
I pretty new to writing PL/SQL packages.
We are using Application express for our development. We get CSV files which is stored as a BLOB content in a table. I need to write a trigger that would get executed once the user the uploads the file and parse thru the Blob content and upload or stage the data in a different table.
I would like to see if there is any tutorial or article that could explain the above process with the example or sample code to do the same. Any help in this regard will be highly appreciated.

Hi,
This is slightly unusual but at the same time easy to solve. You can read through a blob using the dbms_lob package, which is one of the Oracle supplied packages. This is presumably the bit you are missing, as once you know how you read a lob the rest is programming 101.
Alternatively, you could write the lob out to a file on the server using another built in package called utl_file. This file can be parsed using an appropriately defined external table. External tables are the easiest way of reading data from flat files, including csv.
I say unusual because why are you loading a csv file into a blob? A clob is almost understandable but if you can load into a column in a table why not skip this bit and just load the data as it comes in straight into the right table?
All of what I have described is documented functionality, assuming you are on 9i or greater. But you didn't provide a version so I can't provide a link to the documentation ;)

CLR Procedure and returning large number of rows

I have a CLR stored procedure coded in C# that retrieves data from a web service, and returns that data using SendResultsStart/SendResultsRow/SendResultsEnd. This all works fine, except when the data from the web service is tens or even thousands of records.
The code itself takes about 3 minutes on average to do all it's work with around 50000-60000 records, but the procedure does not return in SSMS for about another 10-15 minutes, during which time the CPU and memory usage go up significantly.
To rule out any of the CLR code as the culprit, I created a very simple CLR procedure that just loops to return 100000 records with int and nvarchar(256) fields with the current count, and "ABC" followed by the count. Here is the code:
[Microsoft.SqlServer.Server.SqlProcedure]
public static void ABC()
System.Diagnostics.Stopwatch ExecuteTimer = System.Diagnostics.Stopwatch.StartNew();
SqlMetaData[] ResultMetaData = new SqlMetaData[2];
ResultMetaData[0] = new SqlMetaData("count", SqlDbType.Int);
ResultMetaData[1] = new SqlMetaData("text", SqlDbType.NVarChar, 256);
SqlContext.Pipe.SendResultsStart(new SqlDataRecord(ResultMetaData));
for (int x = 0; x < 100000; x++)
SqlDataRecord ResultItem = new SqlDataRecord(ResultMetaData);
ResultItem.SetValue(0, x);
ResultItem.SetValue(1, "ABC" + x.ToString());
SqlContext.Pipe.SendResultsRow(ResultItem);
SqlContext.Pipe.SendResultsEnd();
TimeSpan ExecTime = ExecuteTimer.Elapsed;
SqlContext.Pipe.Send("Elapsed Time: " + ExecTime.Minutes.ToString() + ":" + ExecTime.Seconds.ToString() + "." + ExecTime.Milliseconds.ToString());
I then executed procedure ABC in SSMS, and it took 21 minutes to return. All of the data rows were visible after just a couple of seconds, but the query continued to run as the CPU and memory went up again.
Is this really how long it should take to return 100000 rows, or am I missing something? Is there a better approach than using SendResultsStart/SendResultsRow/SendResultsEnd?
I've googled this to death and haven't found anything that helped or even explained why this is.
I would greatly appreciate any suggestions or alternate methods to achieve this faster.
Thanks!
Alex

When you create a new object, space on the garbage-collected heap is allocated for that object, and the address will be stored in a reference. Some time later, there will no longer be any references that hold the address of the allocated object. It doesn't
matter whether the reference count went to 0 because the reference was set to null or because the reference was on the stack and is no longer in lexical scope, the end result is the same: the garbage collector will, at some point in time, have to perform the
book-keeping operations necessary to identify that the space allocated for that now-unreferenced object can be re-used. When, on the other hand, you only create a single SqlDataRecord object and hold onto the reference, all of the book-keeping operations
associated with creating 100,000 objects are eliminated. This is why the documentation for the SqlDataReader class advises that:
When writing common language runtime (CLR) applications, you should re-use existing
SqlDataRecord objects instead of creating new ones every time. Creating many new
SqlDataRecord objects could severely deplete memory and adversely affect performance.

Universe object that returns the number of rows in table?

Is it possible to create a Universe object to support the following SQL query:
SELECT * FROM (SELECT ROWNUM rownum1 FROM TABLE) WHERE rownum1 = (SELECT (MAX(ROWNUM)) FROM TABLE)

Amr,
Hey dude, welcome back, long time no hear from you.
You were on the right track with "number of rows", but here is the correct syntax:
=NumberOfRows([Query 1])
