HTTP Question

Running Virtuoso Interactive SQL query via HTTP

I want to know if it is possible to run an isql query via HTTP in OpenLink Virtuoso.

I understand that the isql server runs on port 1111, but I cannot find any example (e.g. curl) to run an SQL query (not SPARQL) via HTTP.

I don't want to use ODBC because that would require configuration on different environments (UNIX or Windows) and I don't have time to change our Vagrant scripts for that.

JDBC is also not an option because we run on NodeJS and that would require a wrapper that would put additional overhead on the query times.

Running OpenLink Virtuoso 7.

The data service at 1111 is not an HTTP service, so curl cannot be used against it.

You may be able to script something to run against the HTTP-accessible iSQL implementation at <http://{{virtuoso-host:port}}/conductor/isql.vspx>. Note that this is digest-auth protected and was intended for human interaction, so the client tool may need to parse the HTML of the response.

If that won't serve your needs, I suggest you ask on the Virtuoso Users mailing list. There are likely other options.
