fix: correct naming of aggregated results when using variables#38
Conversation
Using aggregates with a variable (e.g., `{ v: "?v$sum" }`) would incorrectly generate SPARQL queries like "(SUM(?v) AS ?v)", leading to invalid queries in stricter engines like GraphDB. The naming convention is now adjusted to generate unique variable names, such as "(SUM(?v) AS ?v_sum)". This was already the case when using expressions such as "$schema:value$sum", but it didn't apply to variables. This commit fixes that behavior.

Using aggregates with a variable (e.g.,
{ v: "?v$sum" }) would "incorrectly" generate SPARQL queries like:(SUM(?v) AS ?v). While technically accepted/ignored by Virtuoso, it causes errors with stricter engines like GraphDB.The naming convention is now adjusted to generate unique variable names, such as
(SUM(?v) AS ?v_sum).It was already the case when using expressions such as
$schema:value$sum, but it didn't apply to variables.This commit fixes that behavior.
