Verified Answer
Consider the following SQL code:SELECT CustomerID, COUNT(OrderID) FROM...
The HAVING clause in SQL is used to filter grouped data based on conditions. In this case, it retrieves the CustomerID and OrderID columns from the Orders table, groups them by CustomerID, and counts the total number of orders for each customer, excluding customers with less than or equal to 5 orders.

Consider the following SQL code:SELECT CustomerID, COUNT(OrderID) FROM...
Explanation:
- SELECT Statement:
The SELECT statement retrieves the CustomerID and OrderID columns from the Orders table.
- GROUP BY Clause:
The GROUP BY clause groups the results by CustomerID, allowing us to count the total number of orders for each customer.
- COUNT Function:
The COUNT function is used to count the number of OrderIDs for each CustomerID group.
- HAVING Clause:
The HAVING clause filters the groups based on the condition COUNT(OrderID) > 5, meaning it will exclude customers with less than or equal to 5 orders.
- Final Result:
Therefore, the code retrieves the CustomerID and counts the total number of orders for each customer, excluding customers with less than or equal to 5 orders.
