db

Very simple database package based on reform.

import "github.com/compo-io/db"

Usage

var (

	// ErrNoRows is returned when no rows are found
	ErrNoRows = reform.ErrNoRows

	// ErrInitialized is returned when the database is already initialized
	ErrInitialized = errors.New("database already initialized")
)

func Get

func Get() *reform.DB

Get returns database connection if the package was initialized using Init() method, returns nil otherwise. Make sure your are calling Init() before any queries.

func Init

func Init(dsn *string, driver *string) error

Init is initializing the database using optional dsn and driver. It will use default values if nil is passed. This method can only be called once, or will return an error ErrInitialized.

Example

package main

import (
    "log"

    "github.com/compo-io/db"
)

func main() {
    if err := db.Init(nil,nil); err != nil {
        log.Fatal(err)
    }

    db.Get().Query("SELECT * FROM users WHERE id = ?", 1)
}
