Using Aggregate Functions.
This module describes how to use aggregate functions.
When you use aggregate functions, you usually must also create a GROUP BY clause.
You often see these functions(for example, Sum, Count, and Avg) referred to as aggregate functions.
In contrast, many of the aggregate functions work only on data in fields set to a specific data type.
Access provides two ways to add Count and other aggregate functions to a query.
In contrast, many of the aggregate functions work only on data in fields set to a specific data type.
You can't update data if more than one base table is affected orthe view contains aggregate functions or a DISTINCT clause.
Remember that Access provides more aggregate functions for queries than it does for the Total row.
Also, if you work with an Access project(an Access front end connected to a Microsoft SQL Server database),you can use the larger set of aggregate functions that SQL Server provides.
You use aggregate functions when you need to calculate a single value, such as a sum or an average.
Remember that Access provides additional aggregate functions, but you must use them in queries.
Domain aggregate functions return statistical information about a specific domain or set of records.
For more information aboutthe available aggregate functions, see the article SQL Aggregate Functions.
Operands in expr can include the name of a table field, a constant, or a function(which can be either intrinsic or user-defined but not one of the other SQL aggregate functions).
If you apply aggregate functions to all the fields in a query, you do not have to create the GROUP BY clause.
Note: The how-to sections in this document emphasize using the Sum function, but remember that you can use other aggregate functions in your Total rows and queries.
In a SQL statement that contains aggregate functions, lists fields that are not summarized in the SELECT clause.
You use totals queries and aggregate functions only when you need to find data that falls into a set of groups or categories.
For example, continuing the previous example,if your SELECT clause applies an aggregate function to[E-mail Address] but not to Company, your GROUP BY clause would resemble the following.
The groups are created by cross-referencing columns included in the GROUP BY clause,and then applying the query's aggregate function to produce summary values for the additional super-aggregate rows.
Indicates that the contents of the data column are being summarized for output(are included in a SUM, AVG,or other aggregate function).
So we will begin with the Aggregate Function Differential.
Use the Aggregate Differential Function to solve the formula we learned last time.
You then use an aggregate function, such as Max or Min to return the highest or lowest value, or First or Last to return the earliest or latest date.
This application also has some analytics functions to collect and aggregate statistics.
