Bigquery Entity Tag - go

Question

When I loaded my data from Cloud Storage into Bigquery, the click_url field turned into Record type when get created even though it's a string (maybe because of the noindex not sure tho). When I try to insert the data into BigQuery using Inserter. I got this error message:
Cannot convert std::string to a record field:optional .Msg_0_CLOUD_QUERY_TABLE.Msg_1_CLOUD_QUERY_TABLE_click_url click_url = 1
Table in bigquery:
Schema:
Here's the code:
type Product struct {
Name string `datastore:"name" bigquery:"name"`
ClickUrl string `datastore:"click_url,noindex" bigquery:"click_url"`
DateAdded time.Time `datastore:"date_added" bigquery:"date_added"`
}
func insertRows(data interface{}) error {
projectID := "my-project-id"
datasetID := "mydataset"
tableID := "mytable"
ctx := context.Background()
client, err := bigquery.NewClient(ctx, projectID)
if err != nil {
return fmt.Errorf("bigquery.NewClient: %v", err)
}
defer client.Close()
inserter := client.Dataset(datasetID).Table(tableID).Inserter()
if err := inserter.Put(ctx, data); err != nil {
return err
}
return nil
}
func main() {
product := Product{"product_name", "click_url", "date_added_value"} // Example data from datastore
if err := insertRows(product); err != nil {
fmt.Println(err)
}
}
What should I put on the entity tag "bigquery:click_url" to make this work?

Answer 1

Because the ClickUrl in BigQuery is a STRUCT type, which has key-value pairs.
Maybe try this?
type Product struct {
Name string `datastore:"name" bigquery:"name"`
ClickUrl struct {
String string
Text string
Provided string
} `datastore:"click_url,noindex" bigquery:"click_url"`
DateAdded time.Time `datastore:"date_added" bigquery:"date_added"`
}
