Hi everyone! I I have the following documents:
Person{ "vehicle": { "couchId": "someid" } }
OtherThing:
{ "name": "thing one", "vehicle": { "couchId": "someid" } } { "name": "thing two", "vehicle": { "couchId": "someid" } }
I need to get all person with other thing names. I used join for this purpose.
QueryBuilder .selectDistinct( SelectResult.expression(Expression.property("name").from("others"), .... ) .from(datasource.as("persons")) .join(Join.leftJoin(datasource.as("others")).on(Expression.property("vehicle.couchId").from("persons").equalTo(Expression.property("vehicle.couchId").from("others"))
but when I am executing this query I’m receiving only one string, but I want to an get array like this
["thing one", "thing two"]
for each matched person. How can I get this behaviour? How can I transform multiple matched items in my join to an array not to single item in the SelectResult?I wanted to use group by and array_agg function for this, but couchbaselite for android doesn’t support array_agg((
Thanks in advance.
