I have to make REST calls to a triple store using SPARQL queries. SPARQL queries are similar to SQL but use braces, so the simplest SPARQL query would look like: SELECT * WHERE { ?s ?p ?o . }
If I want to construct a SPARQL query with the current value from 'select1', it would look like the following: SELECT * WHERE { {{select1.value}} ?p ?o .}, or some such. If I write it this way in the query editor the {{select1.value}} resolves, but the query fails with 404 errors. If I put the query in the resource the {{select1.value}} doesn't resolve and I get syntax errors. If I hard code a value in place of {{select1.value}}, in the resource, the query executes and returns valid results. I have also tried to construct the SPARQL query as a concatenated string as follows: "SELECT * WHERE { " + {{select1.value}} + " ?p ?o .}" but also got syntax errors for the quotes but the {{select1.value}} resolved (again, in the query but not in the resource). Clearly I do not understand the relationship between query and resource even though I thought I did, and of course I do not know what the syntactic requirements are for constructing a SPARQL query in Retool.
Does anyone know how to construct a query using syntax that requires embedded curly braces using Retool? Thank you.
