First create a spanner.Client to use throughout your application:
client, err := spanner.NewClient(ctx, "projects/P/instances/I/databases/D")
if err != nil {
log.Fatal(err)
}// Simple Reads And Writes
_, err = client.Apply(ctx, []*spanner.Mutation{
spanner.Insert("Users",
[]string{"name", "email"},
[]interface{}{"alice", "[email protected]"})})
if err != nil {
log.Fatal(err)
}
row, err := client.Single().ReadRow(ctx, "Users",
spanner.Key{"alice"}, []string{"email"})
if err != nil {
log.Fatal(err)
}
