  Provides utility functions that generate Column expressions that you can pass to DataFrame transformation methods.

  Provides utility functions that generate Column expressions that you can pass to DataFrame transformation methods. These functions generate references to columns, literals, and SQL expressions (e.g. "c + 1").

  This object also provides functions that correspond to Snowflake system-defined functions (built-in functions), including functions for aggregation and window functions.

  The following examples demonstrate the use of some of these functions:

      // Use columns and literals in expressions.
      df.select(col("c") + lit(1))

      // Call system-defined (built-in) functions.
      // This example calls the function that corresponds to the ADD_MONTHS() SQL function.
      df.select(add_months(col("d"), lit(3)))

      // Call system-defined functions that have no corresponding function in the functions object.
      // This example calls the RADIANS() SQL function, passing in values from the column "e".
      df.select(callBuiltin("radians", col("e")))

      // Call a user-defined function (UDF) by name.
      df.select(callUDF("some_func", col("c")))

      // Register and call an anonymous UDF.
      val myudf = udf((x:Int) => x + x)
      df.select(myudf(col("c")))

      // Evaluate an SQL expression
      df.select(sqlExpr("c + 1"))

  For functions that accept scala types, e.g. callUdf, callBuiltin, lit(), the mapping from scala types to Snowflake types is as follows:

      String => String
      Byte => TinyInt
      Int => Int
      Short => SmallInt
      Long => BigInt
      Float => Float
      Double => Double
      Decimal => Number
      Boolean => Boolean
      Array => Array
      Timestamp => Timestamp
      Date => Date

###

#### case class builtin(functionName: String) extends Product with Serializable

Function object to invoke a Snowflake builtin. Use this to invoke any builtins not explicitly listed in this object.

Example

    val repeat = functions.builtin("repeat")
    df.select(repeat(col("col_1"), 3))
