SQLCredo

SQLCredo is a type-safe generic SQL CRUD operations wrapper for Go, built on top of sqlx and goqu.

The idea of the package to provide basic CRUD and pagination operations out of the box and simplify adding custom raw SQL-queries to extend functionality.

Features

• Generic type-safe CRUD operations
• Built-in pagination support
• SQL query debugging capabilities
• Support for multiple SQL drivers (tested on sqlite3 and postgres (pgx))
• Transaction support
• Prepared statements by default

Installation

go get github.com/Klojer/sqlcredo

Quick Start

import (
 "context"
 "database/sql"

 "github/Klojer/sqlcredo"
 "github/Klojer/sqlcredo/pkg/model"
)

type User struct {
 ID   int    `db:"id"`
 Name string `db:"name"`
}

func main() {
 ctx := context.Background()

 // Create a new SQLCredo instance
 db, _ := sql.Open("sqlite3", "test.db")
 repo := sqlcredo.NewSQLCredo[User, int](db, "sqlite3", "users", "id")

 // Create
 user := User{ID: 1, Name: "John"}
 _, err := repo.Create(ctx, &user)
 orPanic(err)

 // Read
 users, err := repo.GetAll(ctx)
 orPanic(err)

 // Read with pagination
 page, err := repo.GetPage(ctx,
  model.WithPageNumber(0),
  model.WithPageSize(10),
  model.WithSortBy("name"))
 orPanic(err)

 // Update
 _, err = repo.Update(ctx, 1, &user)
 orPanic(err)

 // Delete
 _, err = repo.Delete(ctx, 1)
 orPanic(err)
}

func orPanic(err error) {
 if err == nil {
  return
 }
 panic(err)
}

See example of repository with custom query: examples/users/users.go

Debug Support

Enable SQL query debugging:

repo.WithDebugFunc(func(sql string, args ...any) {
    log.Printf("SQL: %s Args: %v", sql, args)
})
