Aggregate Functions

Overview

As of release 34.0, Export ZOQL supports several aggregate functions, detailed below.

Note that Export ZOQL is used for creating exports from Zuora data sources, and uses a different syntax than standard ZOQL.

avg()

Use avg() to return the average value. 

Limitations

The avg() function supports only numeric values. 

Example

select A.a,avg(A.c) from A group by A.a, B.b

count()

Use count() to return the number of rows. Similar to standard SQL, you can use the following syntax with count():

  • count(*)
  • count(field)

​The count() command is the only Export ZOQL command that supports the use of an asterisk (*). 

Example

select count(*) from A

max()

Use max() to return the largest value.

Example

select count(a),max(c),b from A group by b

min()

Use min() to return the smallest value.

Example

select count(a),min(c),b from A group by b

sum()

Use sum() to return the sum.

Limitations

The sum() function supports only numeric values. 

Example

select A.a, sum(A.b) from A

Limitations of the Aggregate Functions

The aggregate functions have the same limitations as standard SQL aggregate functions.

In addition to specific limitations, you cannot nest aggregate functions.
