Description
Query involving unnest or nest and with presence of array index results in: "
syntax error - at )"
To repro:
- create default bucket
- create primary index on default
- CREATE INDEX `nested_idx_attr_nest` ON `default`((all (array (distinct (array (`j`.`region1`) for `j` in (`i`.`Marketing`) end)) for `i` in `tasks` end)),`tasks`,`name`);
- explain SELECT emp.name FROM default emp UNNEST emp.tasks as i UNNEST i.Marketing as j where j.region1 = 'South' ;
with index you will see:
cbq> explain SELECT emp.name FROM default emp UNNEST emp.tasks as i UNNEST i.Marketing as j where j.region1 = 'South' ; |

without index works fine:
cbq> explain SELECT emp.name FROM default emp UNNEST emp.tasks as i UNNEST i.Marketing as j where j.region1 = 'South' ; |
