Description

SUM calculates the sum over an INT or FLOAT column.

The data type of the result is the same as the input column data type. So the sum of an INT column will be of type INT.

Syntax

SUM ( table.column )

Null handling

Null values are ignored, meaning that they don't influence the result. If all values of a group are null, the result for this group is also null.

Tips

If the size of the source column greatly exceeds the number of aggregated groups, the sum for each group will be executed in parallel. Therefore, to achieve a good performance, multiple CPU cores and balanced aggregation (as described) are preferable.(Since:  CELONIS 4.3)

Example

Sum of small integers.
