## product

product — aggregate function to return the cumulative multipication product of a range of values.

## SYNOPSIS

## DESCRIPTION

This function computes a value for each record from the specified column of a base table, and returns the cumulative multiplication product of those values.

Expression `expr` must include the name of a column in a LiveView table, where that column's data type is int, long, or double. The returned value is of the same data type.

## SEE ALSO

This LiveView aggregate function is based on the product aggregate function in the StreamBase expression language.
