BigQuery SQL Driver for Golang

This is an implementation of the BigQuery Client as a database/sql/driver for easy integration and usage.

Goals of project

This project is meant to be a basic database/sql driver implementation for Golang so that developers can easily use tools like Gorm, and *sql.DB functions, with Google's BigQuery database.

Usage

Check out the example application in the examples directory, for a few examples.

As this is using the Google Cloud Go SDK, you will need to have your credentials available via the GOOGLE_APPLICATION_CREDENTIALS environment variable point to your credential JSON file.

Vanilla *sql.DB usage

Just like any other database/sql driver you'll need to import it

package main

import (
    "database/sql"
    _ "github.com/tozh/go-sql-bigquery"
    "log"
)

func main() {
    db, err := sql.Open("bigquery", 
        "bigquery://projectid/dataset")
    if err != nil {
        log.Fatal(err)
    }
    defer db.Close() 
    // Do Something with the DB

}

Gorm Usage

For gorm

package main

import (
    "github.com/jinzhu/gorm"
    _ "github.com/tozh/go-sql-bigquery/dialects/bigquery"
    "log"
)

func main() {
    db, err := gorm.Open("bigquery", 
        "bigquery://projectid/dataset")
    if err != nil {
        log.Fatal(err)
    }
    defer db.Close() 
    // Do Something with the DB

}
