AWITH cte_name AS (SELECT ...) SELECT * FROM cte_name;

BDEFINE cte_name AS (SELECT ...) SELECT * FROM cte_name;

CCREATE CTE cte_name AS SELECT ...;

DSELECT * FROM WITH cte_name AS (SELECT ...)

Step-by-Step Solution

Solution:

Step 1: Recall the standard CTE syntax
The correct syntax starts with WITH cte_name AS (subquery), followed by the main query.
Step 2: Check each option
WITH cte_name AS (SELECT ...) SELECT * FROM cte_name; correctly shows the CTE definition and usage. Options A, B, and C use invalid keywords or order.
Final Answer:
WITH cte_name AS (SELECT ...) SELECT * FROM cte_name; -> Option A
Quick Check:
CTE syntax starts with WITH = D [OK]

Quick Trick: CTE always starts with WITH keyword followed by AS [OK]
