# go-sqlla

Type safe, reflect free, generative SQL Builder

## INSTALL

```

$ go install github.com/mackee/go-sqlla/v2/cmd/sqlla@latest

```

## SYNOPSIS

**person.go**:

```go

package table

//go:generate sqlla

//+table: person

type Person struct {

	ID uint64 `db:"id"`

	FirstName string `db:"first_name"`

	LastName  string `db:"last_name"`

}

```

Run generate:

```

$ ls

person.go

$ go generate

$ ls

person.go person_auto.go

```

Same package as the person.go:

```go

import (

	"database/sql"

	"log"

	_ "github.com/mattn/go-sqlite3"

)

func main() {

	db, err := sql.Open("sqlite3", "./foo.db")

	if err != nil {

		log.Fatalf("failed connect database: %s", err)

	}

	q := NewPersonSQL().Select().ID(uint64(1))

	query, args, err := q.ToSql()

	if err != nil {

		log.Fatalf("query build error: %s", err)

	}

	row := db.QueryRow(query, args...)

	var id uint64

	var firstName, lastName string

	err = row.Scan(&id, &firstName, &lastName)

	if err != nil {

		log.Fatalf("query exec error: %s", err)

	}

	log.Printf("id=%d, first_name=%s, last_name=%s", id, firstName, lastName)

}

```
