bigquery:

Higher level Go wrapper for the google Big Query API

Wraps the core big query google API exposing a simple client interface

Usage

// basic use
// To get the JSON credantials file : Google Developers Console -> API Console -> Credentials -> Add Credentials -> Add Service Account -> Download JSON key
bqClient := client.New(JSON_PEM_PATH)

// run a sync query
query := "select * from publicdata:samples.shakespeare limit 100;"

rows, headers, err := bqClient.Query("shakespeare", DATASET, query)
if err != nil {
  fmt.Println("Error: ", err)
} else {
  fmt.Println("Got rows: ", len(rows))
  fmt.Println("Headers: ", headers)
  fmt.Println("Rows: ", rows)
}

// =================================================================
query := "select * from publicdata:samples.shakespeare limit 100;"

bqClient := client.New(JSON_PEM_PATH)

// run a sync query
query := "select * from publicdata:samples.shakespeare limit 500;"

dataChan := make(chan client.Data)
go bqClient.AsyncQuery(100, DATASET, PROJECTID, query, dataChan)

L:
    for {
      select {
      case d, ok := <-dataChan:
          if d.Err != nil {
              fmt.Println("Error with data: ", d.Err)
              break L
          }

          if d.Rows != nil && d.Headers != nil {
              fmt.Println("Got rows: ", len(d.Rows))
              fmt.Println("Headers: ", d.Headers)
          }

          if !ok {
              fmt.Println("Data channel closed")
              break L
          }
