Understanding the Difference Between WHERE and HAVING Clause in MySQL

When working with MySQL queries, it's crucial to grasp the distinction between the WHERE and HAVING clause. The focus keyword in this context is "WHERE vs HAVING clause in MySQL."

The WHERE clause is used to filter records before grouping and aggregation functions are applied. It is primarily used to restrict the result set based on specified conditions. On the other hand, the HAVING clause is used to filter records after the GROUP BY clause, and it is applied to aggregated functions like COUNT, SUM, AVG, etc.

In summary, while the WHERE clause filters individual rows based on specified conditions, the HAVING clause filters grouped rows based on specified conditions after the grouping operation. Understanding when to use each clause is essential for writing efficient and accurate MySQL queries.

By utilizing the WHERE and HAVING clauses effectively, you can enhance the performance of your MySQL queries and retrieve the desired results accurately.
