The use of CSUM is strongly discouraged. It is a Teradata extension to the ANSI SQL:2011 standard, and is equivalent to the ANSI-compliant SUM window function that specifies ROWS UNBOUNDED PRECEDING as its aggregation group. CSUM is retained only for backward compatibility with existing applications.
