Decimal scale in Redshift after division by literal

WebAmazon Redshift treats decimal values as if they are different static types and allows all mathematical operations. Amazon Redshift computes the resulting scale dynamically based on the scales of the operands. If one of the operands is a floating-point number, then Amazon Redshift promotes the other operand to a floating-point number and ... WebSpecifically, DATEDIFF determines the number of date part boundaries that are crossed between two expressions. For example, suppose that you're calculating the difference in years between two dates, 12-31-2008 and 01-01-2009. In this case, the function returns 1 year despite the fact that these dates are only one day apart.
