There are two methods to do SQL over REST:
a) GET method: curl http://root:admin@localhost:4321/sql/[SCHEMA]/[SQL_QUERY]
b) POST method: curl -X POST -d '[SQL_QUERY]' http://root:admin@localhost:4321/sql/[SCHEMA]
JSONL results
The result is a jsonl document containing the result lines:
curl -X POST -d 'select a, sum(b) as sum_b from a group by a' http://root:admin@localhost:4321/sql/test
returns
{"a": 1, "sum_b": 7}
{"a": 2, "sum_b": 6}
{"a": 6, "sum_b": null}
PostgreSQL Syntax Mode
To use the postgresql syntax mode, just use other REST endpoints:
a) GET method: curl http://root:admin@localhost:4321/psql/[SCHEMA]/[SQL_QUERY]
b) POST method: curl -X POST -d '[SQL_QUERY]' http://root:admin@localhost:4321/psql/[SCHEMA]
