Solution

The correct answer is C. WHERE is used to filter rows before aggregation, whereas HAVING is used to filter groups after aggregation.

Here's a step-by-step explanation:

  1. WHERE clause: The WHERE clause is used in SQL to filter records that are necessary according to a certain condition. It is used before the aggregation process. This means that the WHERE clause filters the rows before they are summarized by GROUP BY.

  2. HAVING clause: The HAVING clause is used to filter the results of a GROUP BY query. It operates on the results of the aggregation, filtering groups based on a condition. This means that the HAVING clause filters the rows after they have been grouped.

So, the main difference between WHERE and HAVING in SQL syntax is when they filter the data - WHERE does it before aggregation, and HAVING does it after.
