    Establishes a connection with a Snowflake database and provides methods for creating DataFrames and accessing objects for working with files in stages.

    Establishes a connection with a Snowflake database and provides methods for creating DataFrames and accessing objects for working with files in stages.

    When you create a Session object, you provide configuration settings to establish a connection with a Snowflake database (e.g. the URL for the account, a user name, etc.). You can specify these settings in a configuration file or in a Map that associates configuration setting names with values.

    To create a Session from a file:

    val session = Session.builder.configFile("/path/to/file.properties").create

    To create a Session from a map of configuration properties:

    val configMap = Map(
"URL" -> "demo.snowflakecomputing.com",
"USER" -> "testUser",
"PASSWORD" -> "******",
"ROLE" -> "myrole",
"WAREHOUSE" -> "warehouse1",
"DB" -> "db1",
"SCHEMA" -> "schema1"
)
Session.builder.configs(configMap).create

    Session contains functions to construct DataFrames like Session.table, Session.sql, and Session.read

  • implicits

object implicits extends Implicits with Serializable

Provides implicit methods for convert Scala objects to Snowpark DataFrame and Column objects.

To use this, import session.implicits._ :

val session = Session.builder.configFile(..).create
import session.implicits._

After you import this, you can call the toDF method of a Seq to convert a sequence to a DataFrame:

// Create a DataFrame from a local sequence of integers.
val df = (1 to 10).toDF("a")
val df = Seq((1, "one"), (2, "two")).toDF("a", "b")

You can also refer to columns in DataFrames by using $"colName" and 'colName:

// Refer to a column in a DataFrame by using $"colName".
val df = session.table("T").filter($"a" > 1)
// Refer to columns by using 'colName.
val df = session.table("T").filter('a > 1)
