SHQL is a SQL database written in shell script. It was originally developed by Bruce Momjian. I started playing with it and thought it was interesting and started expanding it. The result is a very different version of shql. Many changes had been made and many features have been added. See the readme file for more information and the changes file for a loose list of my changes.
Included in the tarball is a program to convert CSV files into SQL formatted for shql. It is based on a CSV parser I wrote in AWK. It has it's own page.
It is available as a
Gziped tar file.
Versions 1.1, 1.2 and 1.3 are still available on some mirrors. One such mirror is http://backpan.cpan.org/modules/dbperl/scripts/shql/
