How to perform in query on Hash query? Just like in (“xxx1”, “XXX2”) in SQL statement, I can’t find relevant content in the document. Although regular query can replace it, I’m worried about efficiency
This question isn’t clear to me. Can you elaborate more? With examples.
For example, I have a predicate that is hash indexed. I can use EQ to query exactly one predicate. If I want to query 10 predicates at a time, what statement should I use? For example:
EQ (name, (“Jim”, “Tom”, “Lucy”)), this syntax is not correct, but I want to know the correct way to write
It means how to match “Jim”, “Tom” and “Lucy” exactly at the same time
I think this will do what you want:
eq(name, ["Jim", "Tom", "Lucy"]).
It works in my testing using Dgraph 1.1.1 and is documented here: https://docs.dgraph.io/master/query-language/#inequality
FWIW, you can also use
eq(name, "Jim", "Tom", "Lucy") without the brackets, but that’s not documented and therefore probably shouldn’t be relied upon. Plus, the brackets are easier to parse visually, IMO.
