v2.0.9-pro.1

Support for null values in boolean expressions

In v2, we introduced a breaking change, that aimed at fixing a long-standing issue a null value in a boolean expression would always evaluate to True for all rows. For example, the following queries were all equivalent:

delete_users(where: {\_id: {\_eq: null}}) # field is null, which is as if it were omitted
delete_users(where: {\_id: {}}) # object is empty, evaluates to True for all rows
delete_users(where: {}) # object is empty, evaluates to True for all rows
delete_users() # delete all users

This behaviour was unintuitive, and could be an unpleasant surprise for users that expected the first query to mean "delete all users for whom the id column is null". Therefore in v2, we changed the implementation of boolean operators to reject null values, as we deemed it safer:

delete_users(where: {\_id: {\_eq: null}}) # error: argument of \_eq cannot be null

However, this change broke the workflows of some of our users who were relying on this property of boolean operators. This was used, for instance, to conditionally enable a test:

{{< highlight graphql >}} query($isVerified: Boolean) { users(where: {_isVerified: {_eq: $isVerified}}) { name } } {{< / highlight >}}

We now support the use of the functions ST_3DDWithin and ST_3DIntersects in boolean expressions. Note that ST_3DIntersects requires PostGIS be built with SFCGAL support which may depend on the PostGIS distribution used.

Breaking changes

This version includes breaking changes from previous version (i.e v1.3.3-pro.x).

• Multiple mutations in same request are not transactional

UPDATE (since v2.0.9-pro.1): For only Postgres data source, multiple fields in a mutation will be run in one transaction to preserve backwards compatibility

• Semantics of explicit "null" values in "where" filters have changed

  According to the discussion in [issue 704](https://github. xcom/hasura/graphql-engine/issues/704#issuecomment-635571407), an explicit null value in a comparison input object will be treated as an error rather than resulting in the expression being evaluated to True.

  For example: The mutation delete_users(where: {id: {_eq: $userId}}) { name } will yield an error if $userId is null instead of deleting all users.

  UPDATE (since v2.0.9-pro.1): The old behaviour can be enabled by setting an environment variable: HASURA_GRAPHQL_V1_BOOLEAN_NULL_COLLAPSE: true.

• Semantics of "null" join values in remote schema relationships have changed

  In a remote schema relationship query, the remote schema will be queried when all of the joining arguments are not null values. When there are null value(s), the remote schema won't be queried and the response of the remote relationship field will be null. Earlier, the remote schema was queried with the null value arguments and the response depended upon how the remote schema handled the null arguments but as per user feedback, this behaviour was clearly not expected.

• Order of keys in objects passed as "order_by" operator inputs is not preserved

  The order_by operator accepts an array of objects as input to allow ordering by multiple fields in a given order, i.e. [{field1: sortOrder}, {field2: sortOrder}] but it is also accepts a single object with multiple keys as an input, i.e. {field1: sortOrder, field2: sortOrder}. In earlier versions, Hasura's query parsing logic used to maintain the order of keys in the input object and hence the appropriate order by clauses with the fields in the right order were generated.

  As the GraphQL spec mentions that input object keys are unordered, Hasura v2.0's new and stricter query parsing logic doesn't maintain the order of keys in the input object taking away the guarantee of the generated order by clauses to have the fields in the given order.

  For example: The query fetch_users(order_by: {age: desc, name: asc}) {id name age} which is intended to fetch users ordered by their age and then by their name is now not guaranteed to return results first ordered by age and then by their name as the order_by input is passed as an object. To achieve the expected behaviour, the following query fetch_users(order_by: [{age: desc}, {name: asc}]) {id name age} should be used which uses an array to define the order of fields to generate the appropriate order by clause.

• Incompatibility with older Hasura version remote schemas

  With v2.0, some of the auto-generated schema types have been extended. For example, String_comparison_exp has an additional regex input object field. This means if you have a Hasura API with an older Hasura version added as a remote schema then it will have a type conflict. You should upgrade all Hasura remote schemas to avoid such type conflicts.

• Migrations are not executed under a single transaction

  While applying multiple migrations, in earlier Hasura CLI versions all migration files were run under one transaction block. i.e. if any migration threw an error, all the previously successfully executed migrations would be rolled back. With Hasura CLI v2.0, each migration file is run in its own transaction block but all the migrations are not executed under one. i.e. if any migration throws an error, applying further migrations will be stopped but the other successfully executed migrations up till that point will not be rolled back.
