SELECT column1, column2, 
  CASE 
    WHEN condition1 THEN result1
    WHEN condition2 THEN result2
    ELSE result3
  END AS new_column
FROM your_table;

In this example, column1 and column2 are the columns you want to select from the table your_table. The CASE WHEN statement begins with the CASE keyword followed by multiple WHEN conditions. If condition1 is true, result1 will be returned for the new column new_column. If condition2 is true, result2 will be returned. If none of the conditions are met, result3 will be returned.

You can customize the conditions and results based on your specific requirements. The AS keyword is used to assign an alias to the new column, which is optional.
