SQL-first Golang ORM
最后发布版本: v1.2.1 ( 2024-04-02 22:43:07)
SQL-first Golang ORM for PostgreSQL, MySQL, MSSQL, SQLite and Oracle
Bun is brought to you by :star: uptrace/uptrace. Uptrace is an open-source APM tool that supports distributed tracing, metrics, and logs. You can use it to monitor applications and set up automatic alerts to receive notifications via email, Slack, Telegram, and others.
See OpenTelemetry example which demonstrates how you can use Uptrace to monitor Bun.
Features
- Works with PostgreSQL, MySQL (including MariaDB), MSSQL, SQLite. Oracle.
- ORM-like experience using good old SQL. Bun supports structs, map, scalars, and slices of map/structs/scalars.
- Bulk inserts.
- Bulk updates using common table expressions.
- Bulk deletes.
- Fixtures.
- Migrations.
- Soft deletes.

Why another database client?
So you can elegantly write complex queries:
regionalSales := db.NewSelect().
ColumnExpr("region").
ColumnExpr("SUM(amount) AS total_sales").
TableExpr("orders").
GroupExpr("region")
topRegions := db.NewSelect().
ColumnExpr("region").
TableExpr("regional_sales").
Where("total_sales > (SELECT SUM(total_sales) / 10 FROM regional_sales)")
var items []map[string]interface{}
err := db.NewSelect().
With("regional_sales", regionalSales).
With("top_regions", topRegions).
ColumnExpr("region").
ColumnExpr("product").
ColumnExpr("SUM(quantity) AS product_units").
ColumnExpr("SUM(amount) AS product_sales").
TableExpr("orders").
Where("region IN (SELECT region FROM top_regions)").
GroupExpr("region").
GroupExpr("product").
Scan(ctx, &items)
WITH regional_sales AS (
SELECT region, SUM(amount) AS total_sales
FROM orders
GROUP BY region
), top_regions AS (
SELECT region
FROM regional_sales
WHERE total_sales > (SELECT SUM(total_sales)/10 FROM regional_sales)
)
SELECT region,
product,
SUM(quantity) AS product_units,
SUM(amount) AS product_sales
FROM orders
WHERE region IN (SELECT region FROM top_regions)
GROUP BY region, product
And scan results into scalars, structs, maps, slices of structs/maps/scalars:
users := make([]User, 0)
if err := db.NewSelect().Model(&users).OrderExpr("id ASC").Scan(ctx); err != nil {
panic(err)
}
user1 := new(User)
if err := db.NewSelect().Model(user1).Where("id = ?", 1).Scan(ctx); err != nil {
panic(err)
}
