Beta release of v1.9.0. Please report any issues in the linked discussion.

Core

• cmd: Fix sqlc init (#959)

MySQL

• Generate correct code for booleans
• Calling mysql LAST_INSERT_ID(expr) function (#977)

PostgreSQL

• Support PostgreSQL 12 and 13 features by upgrading to pg_query_go/v2 (#949)
• Fix ALTER TYPE to update column types (#973)

Python

• Add experimental Python support behind the --experimental flag

Changelog

Core

• Initial Windows Support (#886)
• UNION support (#896)
• Publish documentation at https://docs.sqlc.dev
• cmd: Allow config file location to be specified (#863)
• Exit with non-zero error code when parsing fails (#870)

MySQL

• Compile tinyint(1) to bool (#873)
• Support joins in update statements (#883)

Notes

The new MySQL engine, code-named Dolphin, is now default. The old engine has been removed. Your generated code will be different, but should be easy to adapt. Please open an issue if your code is now broken. If you were using the mysql:beta engine, you'll need to change that to mysql.

Changelog

Core

• Add option to return emit db tags for struct fields (#656)
• Add support for variadic stored procedures and functions (#798)
• Fix issue installing sqlc via go get (#744)
• Add support for nontrivial import paths for overrides (#785)

Go

• You can now specify the go_type import path of an override using an object instead of a string.

overrides:
  - db_type: "uuid"
    go_type:
      import: "gopkg.in/guregu/null.v3"
      package: "null"
      type: "Bool"

MySQL

• Add function definitions for all built-in MySQL functions (#796)
• Upgrade to the latest version of pingcap/parser (#744)

Notes

The new MySQL engine, code-named Dolphin, has finally landed. To try it out, use mysql:beta for the engine value in sqlc.json. This uses the same compiler infrastructure as the PostgreSQL engine, giving it feature parity and making it easier to maintain.

The old engine is official deprecated and will be placed behind the mysql:deprecated name in v1.6.0. The engine will be completely removed in v1.7.0. For more information, see the MySQL roadmap.

On the PostgreSQL side of things, I've used some magic to generate function signatures for all built-in functions. This also includes many of the most popular PostgreSQL extensions. You will need to make sure to have CREATE EXTENSION ... in your schema to get this functionality.

Changelog

Core

• Add option to return empty slices (instead of nil slices) in :many queries
• Use "nullable" instead of "null" in configuration file (#571)
• Add debugging support via SQLCDEBUG (#573)
• Support calling functions with defaults (#635)

PostgreSQL

• Add support for the money type (#552)
• Add support for 'cidr' and 'interval' types (#601)
• Generate all functions in pg_catalog (#550)

MySQL

• Add the mysql:beta engine, which will be the default next release

Notes

This release includes a complete refactor of the compiler internals. The compiler now uses a database-agnostic SQL AST. The PostgreSQL backend uses this new code path by default. I've tested the new path extensively, but you still may run into bugs. If you do, you can use the old code path by setting the the following environment variable: SQLC_EXPERIMENTAL_PARSER=off. The old code path will be removed in v1.5.0, so please report any bugs you run into.

A new :execresult query command has been added. The generated methods will return (sql.Result, error), the same as DB.ExecContext.
