Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Open-sourcing SQX, a way to build flexible database models in Go
i like xo's approach https://github.com/xo/xo but it is as is. I would love if something similar comes along that is used by db practititoners that is actively used and supported.

Best sqlc alternative for dynamic queries?
I use xo https://github.com/xo/xo . It generates CRUD queries by default so i don't have to write basic queries and it has option to write complex queries like sqlx. Only issue is it is not well documented.

Why SQL is right for Infrastructure Management
SQL is an old, irregular language to work with, but it is better known than HCL and SQL already has it's own Pulumi/CDK in the form of every ORM with introspection (like Javascript's Prisma, Python's Django, Go's XO etc) and QueryBuilder (LINQ, Knex, etc) in whatever programming language you prefer. You probably already know it.

Help with XO's new templating, how to access fields and params
I am using the library xo to generate basic data retrieval code from a sql schema for a crud api.

Matt Mueller: Building Modern Web Applications Faster With Bud
Sorry for the confusion, we're not generating the database client itself, more like generating an ORM around a database client. The ORM takes these database clients as dependencies. It's very similar to the way XO works with it's multi-database support: https://github.com/xo/xo/tree/master/_examples/northwind

What’s your preferred setup to work with SQL DB (without ORM) ?
i use xo . Reason is i prefer designing schema first and creating golang scaffolding later. Xo takes schema and gives me basic create/update/delete operations by default and i can also generate gocode for any sql queries that i write.

sqlc: Generating go code from sql statements
Thanks for sharing your thoughts! I see that it works best with Postgresql. The other commenter mentioned https://github.com/xo/xo for MySql which might work well.

Thanks for your comment and question @onionisfruit. Top-notch handle too!
>> What are your plans for models and persistence?
I haven't worked out all the details, but it's going to be some blend of https://github.com/xo/xo and https://sqlc.dev/.
Design goals:
1. High-level, type-safe "ORM" that's generated from your database schema.

Ask HN: ORM or Native SQL?
Cornucopia is neat. I wrote a similar library in Go [1] so I'm very interested in comparing design decisions.
The pros of the generated code per query approach:
- App code is coupled to query outputs and inputs (an API of sorts), not database tables. Therefore, you can refactor your DB without changing app code.
- Real SQL with the full breadth of DB features.
- Real type-checking with what the DB supports.
The cons:
- Type mapping is surprisingly hard to get right, especially with composite types and arrays and custom type converters. For example, a query might return multiple jsonb columns but the app code wants to parse them into different structs.
- Dynamic queries don't work with prepared statements. Prepared statements only support values, not identifiers or scalar SQL sub-queries, so the codegen layer needs a mechanism to template SQL. I haven't built this out yet but would like to.

What are the things with Go that have made you wish you were back in Spring/.NET/Django etc?
pggen is another fantastic library in this genre, which specifically targets postgres. It is driven by pgx. Can not recommend enough.

Exiting the Vietnam of Programming: Our Journey in Dropping the ORM (In Golang)
> Do you write out 120 "INSERT" statements, 120 "UPDATE" statements, 120 "DELETE" statements as raw strings
Yes. For example: https://github.com/jschaf/pggen/blob/main/example/erp/order/....
> that is also using an ORM
ORM as a term covers a wide swathe of usage. In the smallest definition, an ORM converts DB tuples to Go structs. In common usage, most folks use ORM to mean a generic query builder plus the type conversion from tuples to structs. For other usages, I prefer the Patterns of Enterprise Application Architecture terms [1] like data-mapper, active record, and table-data gateway.

Back to basics: Writing an application using Go and PostgreSQL
You might like pggen (I’m the author) which only supports Postgres and pgx. https://github.com/jschaf/pggen
pggen occupies the same design space as sqlc but the implementations are quite different. Sqlc figures out the query types using type inference in Go which is nice because you don’t need Postgres at build time. Pggen asks Postgres what the query types are which is nice because it works with any extensions and arbitrarily complex queries.

How We Went All In on sqlc/pgx for Postgres + Go
Any reason to use sqlc over pggen ? If you use Postgres, it seems like the superior option.

What are your favorite packages to use?
Agree with your choices, except go-json which I never tried. pggen is fantastic. Love that library. The underlying driver, pgx, is also really well written.

I don't want to learn your garbage query language
You might like the approach I took with pggen[1] which was inspired by sqlc[2]. You write a SQL query in regular SQL and the tool generates a type-safe Go querier struct with a method for each query.
The primary benefit of pggen and sqlc is that you don't need a different query model; it's just SQL and the tools automate the mapping between database rows and Go structs.

What is the best way to use PostgreSQL with Go?
I created pggen a few weeks ago to create my preferred method of database interaction: I write real SQL queries and I use generated, type-safe Go interfaces to the queries. https://github.com/jschaf/pggen
What are some alternatives?
sqlc - Generate type-safe code from SQL
igor - igor is an abstraction layer for PostgreSQL with a gorm like syntax.
SQLBoiler - Generate a Go ORM tailored to your database schema.
sqlpp11 - A type safe SQL template library for C++
prometheus - The Prometheus monitoring system and time series database.
pggen - A database first code generator focused on postgres
BTrDB - Berkeley Tree Database (BTrDB) server
SqlKata Query Builder - SQL query builder, written in c#, helps you build complex queries easily, supports SqlServer, MySql, PostgreSql, Oracle, Sqlite and Firebird
dat - Go Postgres Data Access Toolkit
