Function select

select(repository?: Repository): Task<string, Tuple>
Creates a task running a feed of SPARQL SELECT queries against a SPARQL repository.

The task emits the tuples matched by each query as a single feed, in query order. Every query runs on its own, outside any transaction, so successive queries may observe different states of a repository that is updated by other clients or by other steps of the same pipeline while the feed is being consumed.
Parameters
- Optionalrepository: Repository
  The target repository; defaults to the createRepository service
Returns Task<string, Tuple>
A task converting a feed of SELECT queries into the feed of tuples they match

Throws
Error If repository is omitted, and either no execution is running or the running one binds no repository to createRepository, as service defines

Throws
Error While the feed is consumed, whatever the source reports while producing queries, or whatever the repository reports while running them
