snowflake.snowpark.functions.iff(condition: Union[Column, str], expr1: Union[Column, None, bool, int, float, str, bytearray, Decimal, date, datetime, time, bytes, list, tuple, dict], expr2: Union[Column, None, bool, int, float, str, bytearray, Decimal, date, datetime, time, bytes, list, tuple, dict]) → Column[source]¶

Returns one of two specified expressions, depending on a condition. This is equivalent to an if-then-else expression.

Parameters:

condition – A Column expression or SQL text representing the specified condition.
expr1 – A Column expression or a literal value, which will be returned if condition is true.
expr2 – A Column expression or a literal value, which will be returned if condition is false.

Examples:

>>> df = session.create_dataframe([True, False, None], schema=["a"])
>>> df.select(iff(df["a"], lit("true"), lit("false")).alias("iff")).collect()
[Row(IFF='true'), Row(IFF='false'), Row(IFF='false')]
