LIMIT 10000This will return unique values for name_1156_20_group_concat, e.g. 8 concat strings in row 1. However, if I simply use
It will only use distinct strings, e.g. only two for row 1. Simple question: Why does GROUP_CONCAT always uses DISTINCT? It doesn't matter if I use

Thanks for this great bug report. The issue is not with SELECT (GROUP_CONCAT(?v) AS ?c) WHERE {
VALUES ?v { "a" "a" }
}but with the SELECT (GROUP_CONCAT(?v; SEPARATOR = ",") AS ?c) WHERE {
VALUES ?v { "a" "a" }
}Fix: #1207 |
