Exporting query result set into CSV file using Forms

Hi ,
My requirement is
-> I need to create a form where I have a Multi line text box and two button.
-> When I enter a query in text box and click on Execute button, It should execute a select query.
-> After execution, Result set needs to be exported into an Excel file.
Please give a hint how to do this????
Thanks,
maddy

as you are using text item to write SQL query by the user
so for that you need to use the exec_sql package to parse the text items query and get definitions and values of the columns being
resulted in the result set of the query.
once your query is execute to the desired connection then you need to use fetch the result to the CSV file by use of the TEXT_io package
which will open the text file with .csv extension and you have to pass the each line to that text file with comma separated values as "ss","rr" etc.
or you can use the ole2 package to call the excel application and then fetch the data of exe_sql query to that.

Export batch data into CSV file using SQL SP

Hi,
I have created WCF-Custom receive adapter to poll Sql SP (WITH xmlnamespaces(DEFAULT 'Namespace' and For XML PATH(''), Type) . Get the result properly in batch while polling and but getting error while converting into CSV by using map.
Please can anyone give me some idea to export SQL data into CSV file using SP.

How are you doing this.
You would have got XML representation for the XML batch received from SQL
You should have a flat-file schema representing the CSV file which you want to send.
Map the received XML representation of data from SQL to flat-file schema
have custom pipeline with flat-file assembler on the assembler stage of the send pipeline.
In the send port use the map which convert received XML from SQL to flat file schema and use the above custom flat-file disassembler send port

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).

Select Query Results to a .csv file????

Hello All,
I have a question in Oracle, if anyone knows how to do this. Please help me.
How can I get the results of select query in Oracle loaded into a Excel file (.csv) file.
Thanks in Advance,
Sarada.

Hi Sarada,
as a csv is nothing more than a list of Comma Separated Values your best shot is to simply read do this with your values. read each value in an iteration add them to a string / stringbuffer and add a "," between them. When you read then next line in the ResultSet you just add a carriage return to the end. Depending on what format you want your csv list in.
After you written all of this into a String you write this out to a file (unless you want to do it slower and write them line by line whenever you read them).
Hope this helps,
Kalle

Using UTL_FILE i'm able to read csv file. I'm stuck up in appending some more columns to same csvYou'll struggle to append data to an existing CSV.
You'd be better to read the data from one CSV, and create another CSV using that data, and the extra data you want, and then when finished, delete the original file and rename the new file to the old filename.
You should be able to do that using External Tables to read the source file (easier than using UTL_FILE) and UTL_FILE to write the new file.

Hello Ben,
Per my knowledge, you cannot use Exchange Management Shell to export the contacts in public folder to csv file.
If you want to export contacts in public folder to a csv file, you can follow this way to do that:
Open Outlook and create a Temp Contact Folder
Move all the contacts to the Temp Contact Folder
Use Outlook export contacts to csv file .

How to export Bi Publisher report into .csv file in different sheets?

Hi,
I have a report request in BI Publisher to generate the results in different tabs in Excel format with headings etc.
But the users are now asking for the same report in .csv format with the same number of tabs in one file.
Can I do that in .csv file?

Can I do that in .csv file?
no
csv is simple plain-text
A comma-separated values (CSV) (also sometimes called character-separated values, because the separator character does not have to be a comma) file stores tabular data (numbers and text) in plain-text form. Plain text means that the file is a sequence of characters, with no data that has to be interpreted instead, as binary numbers. A CSV file consists of any number of records, separated by line breaks of some kind; each record consists of fields, separated by some other character or string, most commonly a literal comma or tab. Usually, all records have an identical sequence of fields.

Export query result to csv using Export Wizard

Been a decade since I last used Oracle and related tools.
I had to use Oracle server again, I have a query over multiple tables, I am to run a scheduled script that will spit out the query result as a csv file.
I started with SQL Developer Export wizard, in step "Specify Data", I am at a loss, where to specify the query itself? I see a Name,Schema,Type input, a text area below, Up,UpAll,Down,DownAll buttons etc etc. Where do I specify my query here? Can someone please help?
Is this the best way to go about to schedule a data export (query to csv) daily?

To export a user query rather than a whole table, run it in a worksheet and export using the context menu on the result grid. However none can be scheduled.
Instead you can look at the SPOOL command and schedule it through SQL*Plus. Any questions can go to the iSQL*Plus and/or SQL And PL/SQL forum.
Have fun,
K.

Saving result from query into CSV file

Hi folks,
in our application we're generating pages source using general packages (like htp, owa_util, ...). and in this part I'm a really beginner.
I want to modify source one of our page, I want to add functionality to enable save result from query (cursor) into CSV file, to enable user choose place where generated file will be created and also change file name.
I searched this forum and I found procedure, that could be useful:
procedure p_getcsv is
cursor cur is
       select 'a1' col1, 'b1' col2, 'c1' col3 from dual
   union select 'a2' col1, 'b2' col2, 'c2' col3 from dual
   union select 'a3' col1, 'b3' col2, 'c3' col3 from dual;
   begin
        -- Set the MIME type
        owa_util.mime_header( 'application/octet', FALSE );
        -- Set the name of the file
        htp.p('Content-Disposition: attachment; filename="test.csv"');
        -- Close the HTTP Header
        owa_util.http_header_close;
        -- Loop through all rows in EMP
        for x in cur
        loop
            -- Print out a portion of a row,
            -- separated by commas and ended by a CR
             htp.prn(x.col1||','|| x.col2||','||x.col3|| chr(13));
        end loop;
   end;What peace of code should I add to procedure that is generating web page to enable calling this procedure and whole saving process?
Can anybody help me with this?
Many thanks,
Tomas

Hi Marc,
thanks for reply, problem is that I'm not using APEX application, I'm just generating web page code straight using oracle general packages.

How to get Document Set property values in a SharePoint library in to a CSV file using Powershell

Hi,
How to get Document Set property values in a SharePoint library into a CSV file using Powershell?
Any help would be greatly appreciated.
Thank you.
AA.

Hi,
According to your description, my understanding is that you want to you want to get document set property value in a SharePoint library and then export into a CSV file using PowerShell.
I suggest you can get the document sets properties like the PowerShell Command below:
[system.reflection.assembly]::loadwithpartialname("microsoft.sharepoint")
$siteurl="http://sp2013sps/sites/test"
$listname="Documents"
$mysite=new-object microsoft.sharepoint.spsite($siteurl)
$myweb=$mysite.openweb()
$list=$myweb.lists[$listname]
foreach($item in $list.items)
if($item.contenttype.name -eq "Document Set")
if($item.folder.itemcount -eq 0)
write-host $item.title
Then you can use Export-Csv PowerShell Command to export to a CSV file.

Export query results to flat file with dynamic filename

Hi
Can anybody can point me how to dynamic export query serults set to for example txt file using process flows in OWB.
Let say I have simple select query
select * from table1 where daterange >= sysdate -1 and daterange < sysdate
so query results will be different every day because daterange will be different. Also I would like to name txt file dynamicly as well
eg. results_20090601.txt, results_20090602.txt, results_20090603.txt
I cant see any activity in process editor to enter custom sql statment, like it is in MSSQL 2000 or 2005
thanks in advance

You can call existing procedures from a process flow the procedure can create the filename with whatever name you desire. OWB maps with file as target can also create a file with a dynamic name defined by an expression (see here ).
Cheers
David
