Hello
I have a working proposal for a small feature, which I would describe in one sentence as
"named parametrized queries".
Basically it allows to save something like this in a file:
--psql:MyQuery1
SELECT 42 FROM @0
WHERE true
--psql:end
--psql:MyQuery2
/* updates stuff... */
UPDATE stuff SET ..
Then, from inside psql, I can invoke the query by its name, and pass an (or many) argument(s).
For example, invoking it like so:
db=# \nq MyQuery1 blabla
Would substitute literally the "@0" with "blabla" and send it to the backend.
I am aware that saving queries is already possible with variables (:var), and saved variables can be sourced from .psqlrc file.
However, I think passing arguments in bash style is kinda nicer, because I don't need to set any variables beforehand. Also this would allow to have a clean and valid SQL (well kinda, if no placeholders "@" is used) and comments.
I have also added autocompletion.
Should I send the diff to the mailing list, or maybe it's not something useful?
Regards
Denis
