Q: Which SQL tool evaluates one or more criteria and, upon the satisfaction of a condition, returns a value?
- THEN
- WHEN
- CASE
- ELSE
Explanation: The CASE statement is a SQL tool that evaluates one or more conditions and provides a value as soon as a condition is satisfied. This tool may be used in conjunction with other SQL tools. You can implement conditional logic in SQL by using the CASE statement, which involves sequentially assessing several conditions and delivering a given result after a condition has been fulfilled. This may come in handy when constructing more complicated queries with the usage of conditional expressions.
