Can we use WHERE and having clause together?

Question

We can combine the WHERE and HAVING clause together in a SELECT query. In this case, the WHERE clause is used first to filter individual rows. The rows are then grouped, perform aggregate calculations, and finally, the HAVING clause is used to filter the groups.

Can WHERE and HAVING be used together?

Yes, an SQL query can contain a WHERE and HAVING clause. You will use these together when you want to extract (or filter) rows for a group of data using a WHERE clause and apply a condition on the aggregate using the HAVING clause.

Can HAVING clause be used with WHERE?

The Having clause is used with aggregate functions (for example sum, count etc.) because the Where clause is not used with aggregate functions. The Having clause is used in a GROUP BY clause. When GROUP BY is not used, most of the time you will get the same result with the Where or Having clause.

Can we use HAVING and WHERE clause in same query?

A query can contain both a WHERE clause and a HAVING clause. In that case: The WHERE clause is applied first to the individual rows in the tables or table-valued objects in the Diagram pane. Only the rows that meet the conditions in the WHERE clause are grouped.

Can we use GROUP BY HAVING and WHERE clause together?

HAVING Clause always utilized in combination with GROUP BY Clause. HAVING Clause restricts the data on the group records rather than individual records. WHERE and HAVING can be used in a single query.
