Good day.
How can we export to BSD in the UaModeler?
I can only export to XML and CSV.
'Export XML' should also generate the .bsd file.

I've got a number of CSV files saved with pandas as zip files. I'd like to read them into KDB without having to manually unzip them in a terminal beforehand.
It looks like KDB supports compression:
https://code.kx.com/q/kb/file-compression/
But I can't figure out how to get it to decompress it. What I read in looks like the literal zip file.
How do I read a zipped CSV file in KDB?
Named pipes can be used for this purpose
https://code.kx.com/q/kb/named-pipes/
q)system"rm -f fifo && mkfifo fifo"
q)system"unzip -p t.zip t.csv > fifo &"
q)trade:flip `sym`time`ex`cond`size`price!"STCCFF"$\:()
q).Q.fps[{`trade insert ("STCCFF";",")0:x}]`:fifo
I heard there was a way to convert an ISF file to PCAP using QCAT by command line but I've not found a way to do so with anything I've read or searched for on the internet.
Anyone know of how to perform this action?
Thanks
From a short Qualcomm slide show:
QCAT runs cmd line to generate the PCAP/TXT. Customer can run cmd line option to generate PCAP/TXT
Executable: C:\Program Files (x86)\Qualcomm\QCAT 6.x\Bin\PCAP Generator.exe Usage: PCAP Generator.exe [input_file] [output_path] [-option]
This command converts a file or directory of .qmdl files into a single .hdf file. The .hdf file will be named the same as the original log file or the directory of the input but with a .hdf extension.
QCAT –hdf file
or
QCAT –hdf directory
I want to export a postgresql table to a csv file.
I have tried two ways, however both are unsuccessful for different reasons.
In the first case, you can see what I run and what I get bellow:
COPY demand.das_april18_pathprocess TO '/home/katerina/das_april18_pathprocess.csv' DELIMITER ',' CSV HEADER;
No such file or directory
SQL state: 58P01
I need to mention that in the location /home/katerina/ I have created an empty file named das_april18_pathprocess.csv, for which I modified the Permission settings to allow Read and Write.
In my second try, the query is executed without any errors but I cannot see the csv file. The command that I run is the following:
COPY demand.das_april18_pathprocess TO '/tmp/das_april18_pathprocess.csv' DELIMITER ',' CSV HEADER;
In the /tmp directory there is no cvs file.
Any advice on how to export the table to csv file with any way is really appreciated!
Ah, you run into a common problem -- you're creating a file on the server's filesystem, not your local filesystem. That can be a pain.
You can, however, COPY TO STDOUT, then redirect the result.
If you're using linux or another unix, the easiest way to do this is from the command line:
$ psql <connection options> -c "COPY demand.das_april18_pathprocess TO STDOUT (FORMAT CSV)" > das_april18_pathprocess.csv
copy ( select * from demand.das_april18_pathprocess) to '/home/katerina/das_april18_pathprocess.csv' with CSV header ;
I am using JasperStarter to create pdf from several jrprint files and then print it using JasperStarter functtions.
I want to create one single pdf file with all the .jrprint files.
If I give command like:
jasperstarter pr a.jprint b.jprint -f pdf -o rep
It does not recognise the files after the first input file.
Can we create one single output file with many input jasper/jrprint files?
Please help.
Thanks,

Looking at the documentation, this is not possible:
The command process (pr)
The command process is for processing a report.
In direct comparison to the command for compiling:
The command compile (cp)
The command compile is for compiling one report or all reports in a directory.
I am trying to export data to existing csv file.
I have been using these methods to export data.
Microsoft.Jet.OLEDB.4.0
SQLCMD
Data Export Wizard
However I cannot find if there is any parameter / option to append the exported data to existing file. Is there any way? Thanks.
Note: answer is biased towards *nix operating systems; I'm not too familiar with windows.
If you can run your sql query via the command line,
using a scripting language, you can use a library that creates an MSSQL connection, (an example of this is a node.js program I authored (https://github.com/skilbjo/aqtl but any tool will do), or
a windows binary that runs something like sqlcmd from the command line,
you can just pipe the output to the csv file. For example:
$ node runquery.js myquery.sql >> existing_csv_file.csv
