The first queston in csv solutions is "Does the data include char with comma or double quotes?"
  • If not, it never needs quoting or escapes.
  • In csv, embedded commas must be double-quoted and embedded double quotes must be doubled! For example, if a column contained ' We said "Hello, sailor!" ', then it needs to be ' "We said ""Hello, sailor!"" ' or even ' We said ""Hello"," sailor!"" ' (double quotes right around the comma)! Many double quote every column against commas, but most forget double quote doubling! In a C/C++/JAVA/PERL program, you can detect comma and only quote on need, whole column in case it has multiple commas, for a minimum file size. CSV is very compressible, too.
You can select into excel with odbc and save as csv!

You can select with any command line tool (isql from unixODBC, jisql for xigole w/JDBC) and use sed or awk to reformat it trimmed with comma separators.

If the tool has a column separator, you can set it to comma, or convert it to comma.

You can put the commas in your select: select col_a || ',' || col_b .... Sometimes the concatenated string exceeds the allowed length unless you break it up.

You can put a marker on the data lines so they are simple to detect and separate from headings, error reports and status:
Code:
echo "
 select 'dAtAq,' || col_a || ',' || col_b || ....
" | isql ... | sed -n '
  s/^dAtAq,//p
  t
  w logfile
 ' > xxx.csv

We could process in bash if you insist.

LEARN ABOUT DEBIAN

cvs-autoreleasedeb

CVS-AUTORELEASEDEB(1)					User Contributed Perl Documentation				     CVS-AUTORELEASEDEB(1)

NAME

       cvs-autoreleasedeb - Automatic Release of debian packages from CVS

DESCRIPTION

       This script generates and uploads the debian package for cvs modules managed by cvs-buildpackage.

       cvs-autoreleasedeb will maintain a state file of all the packages you want to be automatically published, and every time you commit the
       debian/changelog file of your package, changing the debian version to a greater value, it will be published.

       All the parameters to the script are configured in the conffile. There is no command-line switch. See cvs-autoreleasedeb.conf(5) for more
       information.

USING

       There are two ways of using this script:

       1) Run as user cvs-autoreleasedeb in cron. This is very useful for software houses that want to have the "nightily build" version of the
       software published automatically.  In this case, the config file will be "/etc/cvs-autoreleasedeb.conf" and it will use
       /var/lib/cvs-autoreleasedeb/ as scratch dir.

	 NOTE: edit /etc/default/cvs-autoreleasedeb to control this behavior
	 NOTE 2: all output will be thrown in /var/log/cvs-autoreleasedeb/run.log

       2) Run as yourself, it will automatizate the work you will have if you have your packages in CVS.  In this case, the config file will be
       $HOME/.cvs-autoreleasedeb/conf and the scratch dir will be $HOME/.cvs-autoreleasedeb.  cvs-autoreleasedeb will not create defaults, you
       must have the configuration file created before running cvs-autoreleasedeb. See cvs-autoreleasedeb.conf(5).

TODO

	- Use a snapshot of the time of the commit in
	  the changelog to checkout the source
	- Localize the messages.
	- Work with other than all lowercase in conffile.
	- Use a better format for conffile.

_EXIT CODES
	_exit codes:
	0 = Clean _exit
	1 = Config file not found
	2 = No packages in config file
	3 = Couldn't open the state file
	4 = Couldn't open the state file for writing
	5 = Couldn't determine architecture
