IN

expr IN (value, ...)

expr IN (subquery)

If expr is equal to any value in the IN list, return true; otherwise, return false.

Subquery can only return one column, and the column types returned by subquery must be compatible with expr types.

If subquery returns a bitmap data type column, expr must be an integer.
