How Can I Use CASE Statements in SQL SELECT Statements for Conditional Results?

Using CASE with SELECT Statement for Conditional Results

In SQL, the CASE statement allows you to define multiple conditions and assign corresponding results to each condition. When used within a SELECT statement, it enables you to create dynamic expressions based on the evaluation of conditions.

For instance, consider the following example:

SELECT name, age,
CASE
    WHEN bbb THEN 'blackberry'
    WHEN sss THEN 'samsung'
END AS handphone
FROM (
    SELECT ???? .....
)

In this query, the CASE statement is employed to determine the value for the handphone column based on the values in the bbb and sss columns. If bbb evaluates to true, the result will be 'blackberry'; if sss evaluates to true, the result will be 'samsung'. The results would appear as follows:

name                         age       handphone
xxx1                         yyy1      blackberry
xxx2                         yyy2      blackberry
