Aggregate

Abstract

Summarize data by aggregating.

Summarize data by aggregating.

The aggregate operations are: MAX, MIN, COUNT, SUM, AVERAGE, MEDIAN, OR, AND, and STDEV.

You can use the OR and AND functions only with columns that contain Boolean values. The tool returns TRUE if:

  • OR is used and at least one record is true.

  • AND is used and all records are true.

Tip

You can use the COUNT operation without selecting an aggregate column.
