object functions

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

  310. def when ( condition: Column , value: Column ) : CaseExpr

    Works like a cascading if-then-else statement.

    Works like a cascading if-then-else statement. A series of conditions are evaluated in sequence. When a condition evaluates to TRUE, the evaluation stops and the associated result (after THEN) is returned. If none of the conditions evaluate to TRUE, then the result after the optional OTHERWISE is returned, if present; otherwise NULL is returned. For Example:

    import functions._
    df.select(
      when(col("col").is_null, lit(1))
        .when(col("col") === 1, lit(2))
