Features

As a highlight Diesel 2.0.0 adds support for the following features:

  • Fully type checked GROUP BY support
  • Support for table aliasing
  • Support for defining select clauses via a corresponding type
  • Support for UNION/INTERSECT queries

Support for GROUP BY clauses

Diesel 2.0 adds support for GROUP BY clauses for select queries.

This means queries like the following one will just work.

 users::table.inner_join(posts::table)
    .group_by(users::id)
    .select((users::name, count(posts::id)))

As this is the case for all other Diesel built-in query dsl, this construct is fully checked at compile time. This means Diesel will ensure that the GROUP BY clause is valid for the current query and it will also ensure that expressions appearing inside of your SELECT clause will match the aggregation rules provided by the current GROUP BY clause.

Support for table aliasing

Diesel 2.0 adds support for table aliasing. This enables users to write queries, where a table appears more than once in the corresponding FROM clause. For this Diesel provides a Diesel::alias! macro that allows to define new alias for existing tables.

The following query demonstrates the support for this feature:

Changelog

Sourced from diesel's changelog.

[2.0.0] 2022-08-29

Added

  • MysqlConnection::establish is able to initiate an SSL connection while specifying certificate roots. The database URL should contain an ssl_ca parameter with a path pointing to the certificate roots. See docs if desired.

  • MysqlConnection::establish is able to initiate an SSL connection. The database URL should contain ssl_mode parameter with a value of the MySQL client command option --ssl-mode if desired.

  • Connection and SimpleConnection traits are implemented for a broader range of r2d2::PooledConnection<M> types when the r2d2 feature is enabled.

  • Added DatabaseErrorKind::ReadOnlyTransaction to allow applications to handle errors caused by writing when only allowed to read.

  • All expression methods can now be called on expressions of nullable types.

  • Added BoxedSqlQuery. This allows users to do a variable amount of .sql or .bind calls without changing the underlying type.

  • Added .sql to SqlQuery and UncheckedBind to allow appending SQL code to an existing query.

  • The MacAddr SQL type can now be used without enabling the network-address feature.

  • Added support for SQLite's UPSERT. You can use this feature above SQLite version 3.24.0.

  • Added ability to create custom aggregate functions in SQLite.

  • Multiple aggregate expressions can now appear together in the same select clause. See the upgrade notes for details.

  • ValidGrouping has been added to represent whether an expression is valid for a given group by clause, and whether or not it's aggregate. It replaces the functionality of NonAggregate. See the upgrade notes for details.

  • It is now possible to inspect the type of values returned from the database in such a way to support constructing a dynamic value depending on this type.

  • Added a without-deprecated feature that unconditionally disables deprecated items. Use this feature flag to verify that none of your dependencies is setting the with-deprecated flag internally.

  • Added support for PostgreSQL's SIMILAR TO and NOT SIMILAR TO.

  • Added #[diesel(serialize_as)] analogous to #[diesel(deserialize_as)]. This allows customization of the serialization behaviour of Insertable and AsChangeset structs.
