I wish it were possible to execute SQL on tables in org-mode buffers. Filtering
rows and columns, joining values across named tables, and so forth could be
done with SQL in the org-table SEND clauses.
There's a script called csvsql that allows for executing SQL on comma- or
tab-separated files from the command-line (using the H2 database engine):
https://github.com/jdurbin/durbinlib/wiki/csvsql. I'm thinking csvsql or
similar could provide the query capability, and org-mode would take care of
sending it org tables in tab separated format.
That's my wish.
Cheers
Johan
