Hasura Graphql 查询运算符的神秘定义

Question

I'm using a complex derived graphql query in which I want to get all entries between a min and max value. I'm using Hasura's graphql schema for the query.

Heroku's Hasura defines a set of operators for the AggregateObject on their docs page https://docs.hasura.io/1.0/graphql/manual/api-reference/graphql-api/query.html#whereexp for aggregation

The operators are as follows.

_eq _neq _in _nin _gt _lt _gte _lte

However, the Hasura docs don't define what these operators each do, and there are no definitions in the schema analyzer I have available.

Does anyone out there know what each of the following operators in the hasura generated schemas do? Do any of them do min and max?

Answer 1

Equals, not equals, in, not in, greater than, less than, greater than or equal. The docs have some examples: https://docs.hasura.io/1.0/graphql/manual/queries/query-filters.html
