[![Build Status](https://travis-ci.org/ocadaruma/scalikejdbc-bigquery.svg?branch=master)](https://travis-ci.org/ocadaruma/scalikejdbc-bigquery)

ScalikeJDBC extension for Google BigQuery

## Prerequisites

- Java 8

- Scala 2.11.x / 2.12.x / 2.13.x

- ScalikeJDBC 2.4.x or newer

## Installation

```scala

libraryDependencies ++= Seq(

  "com.mayreh" %% "scalikejdbc-bigquery" % "0.1.4",

  "com.google.cloud" % "google-cloud-bigquery" % "1.51.0",

  "org.scalikejdbc" %% "scalikejdbc" % scalikejdbcVersion // specify scalikejdbc version you want. 

)

```

## Usage

```scala

import com.google.auth.oauth2.GoogleCredentials

import com.google.cloud.bigquery.{BigQueryOptions, DatasetId}

import scalikejdbc._, bigquery._

// instantiate BigQuery service and DatsetId

val credentials = GoogleCredentials.fromStream(new FileInputStream("/path/to/key.json"))

val bigQuery = BigQueryOptions.newBuilder()

  .setCredentials(credentials)

  .setProjectId("your-gcp-project-id")

  .build()

  .getService

  

val dataset = DatasetId.of("your-gcp-project-id", "your-dataset")

// build query by QueryDSL then execute

val executor = new QueryExecutor(bigQuery, QueryConfig())

val response = bq {

  selectFrom(User in dataset as u)

    .where.eq(u.id, 42)

}.map(User(_)).single.run(executor)

response.result // => Option[User]

```
