I've been thinking for a while -ever since I happened upon jq(1)- that a
marriage of jq and SQLite3 would be wonderful.
jq is a JSON query language. It's a functional language.
In my mind this would consist of:
- a jq function for sqlite3
- a jq array grouping aggregate function for sqlite3
- a jq virtual table for sqlite3 (for, e.g., disaggregating values)
- a jq binding for sqlite3 (so SQLite3 can be invoked from jq)
The IN array binding could then be handled like this:
sqlite3> SELECT * FROM foo WHERE jq('contains($arg1), :in_list, column1);
The value bound to :in_list would be a JSON array or object (faster for
larger sets) of values.
