int64_null() -> int64

Returns a null value of type int64.

This is important because some functions, like case(), return more convenient outputs if all their arguments are of the same type.

Domain

This is a scalar function (calculates a single output value for a single input row).

Examples

make_col positive_or_null:case(x > 0, x, true, int64_null())

Create a column 'positive_or_null' which is either a positive int64, or the null int64.
