Question
The CASE expression is the same as ________ statement in other programming languages.
- if/else
- while/do
- for
- continue
Solution
The CASE expression in SQL is essentially analogous to the "if/else" statement found in many other programming languages.
Explanation:
-
Functionality Comparison: The CASE expression allows for conditional logic, evaluating expressions and returning a corresponding result based on specified conditions. This is similar to an "if/else" statement where different blocks of code are executed based on a condition being true or false.
-
Control Flow: Just like "if/else", you can have multiple conditions in a CASE expression which makes it possible to implement complex conditional logic. In programming languages, "if/else" statements can also handle multiple branches and allow for default cases with "else", which is comparable to the ELSE portion of the CASE expression.
-
Usage Context: While "if/else" can be utilized in procedural programming to control the flow of execution, CASE is primarily used within SQL queries to determine which value should be returned based on certain criteria.
Given these similarities and functionalities, you can confidently state that the CASE expression in SQL is the same as an "if/else" statement in other programming languages.
