Is it possible somehow to send LIMIT and OFFSET as parameters (not using paging) ?

[rapw3k]

Hi @c-martinez
I would like to be able to specify the LIMIT and OFFSET of the SPARQL inside the query, not automatically via the paging option, see e.g., : https://grlc.io/api-git/ILIAD-ocean-twin/api/#/test/get_Observations_test (not working)
Is this possible somehow?
thanks

Hi @rapw3k,
Sorry for the delay in replying to your issue. I've had a quick look, and it appears it is not possible to do this. Basically, because having something like LIMIT ?top is invalid for SPARQL (limit should not be a SPARQL variable). Of course this would not be a problem once grlc rewrites ?_top to be a value, but because of the order in which grlc replaces variables, it runs into an issue.

@albertmeronyo -- perhaps we should have another look at the query re-writing engine? This seems to be causing a couple of issues.

thanks @c-martinez @albertmeronyo
I am coming back to this (still standing) issue.
That was exactly what i was thinking, if the user variable is replaced before the query is evaluated, then it should work in theory. Do you think it could be possible to update this in grlc ?

[c-martinez]

In principle I think this should be possible indeed. The real question here is on what time frame we could implement this (I know that both @albertmeronyo and I are a bit tied up with other work, but would welcome pull requests implementing these changes)

Haven't tested this, but I believe this should be possible since v1.3.9. I'm closing this issue, but please re-open it if it does not work.
