Can we use aggregate functions to filter values in where clause?
You cannot use aggregate functions in a WHERE clause or in a JOIN condition.
Can WHERE be used with aggregate functions?
An aggregate function can be used in a WHERE clause only if that clause is part of a subquery of a HAVING clause and the column name specified in the expression is a correlated reference to a group.
Can I ORDER BY aggregate function?
An aggregate function cannot be used directly in: an ORDER BY clause. Attempting to do so generates an SQLCODE -73 error. However, you can use an aggregate function in an ORDER BY clause by specifying the corresponding column alias or select-item sequence number.
How do you create a filtered query?
To filter data in a query, open it in Datasheet View, click the down-arrow at the top of a column, and select a filter option. You can select multiple values from the list, but in an app, the filter list closes each time you select an option.
How to filter records with aggregate function Avg?
One is sold by more than one grocer; therefore the average price is calculated for each (in our example, SELECT name, AVG (price) ). Beside the aggregate function, we also use the column name in SELECT, so we should use GROUP BY with this column name ( GROUP BY name ).
How to filter after aggregation in SQL Server?
The query you have is actually doing what you want and not what you expressed in the question. If you want to exclude all sales with a value less than 1000, you should use WHERE sales > 1000. But with HAVING SUM (sales) > 1000 the filtering is actually done after the aggregation.
When to use aggregate function in HAVING clause?
The last step is using the aggregate function in the HAVING clause. Remember that HAVING should be put after the GROUP BY clause. It contains the condition which compares the value returned by the aggregate function with a given value.
