Here is the basic syntax of a Multiple CASE WHEN statement: SELECT column1, column2, CASE WHEN condition1 THEN result1 WHEN condition2 THEN result2 ... ELSE default_result END AS new_column FROM your_table; This construct proves invaluable in handling scenarios where more than one condition needs consideration.
No, CASE is a function, and can only return a single value. I think you are going to have to duplicate your CASE logic. The other option would be to wrap the whole query with an IF and have two separate queries to return results.
Selecting multiple columns through SQL query is as straightforward as listing the columns you want to retrieve, separated by commas.
To do this, we simply list the column names in the SELECT clause, separated by commas, followed by the table name.
The syntax involves specifying the column to search in, followed by the LIKE operator and a pattern or wildcard. Here's an example to illustrate this concept: SELECT FROM table_name WHERE column_name LIKE 'pattern' AND column_name IN ('value1', 'value2'); Copied!

Yes, you can order by multiple columns in SQL using the ORDER BY clause. Simply list the column names separated by commas, and define the sort order (ASC or DESC) for each column.
You can also ORDER BY two or more columns, which creates a nested sort . The default is still ascending, and the column that is listed first in the ORDER BY clause takes precedence. The following query and Figure 3 and the corresponding query results show nested sorts.
The CASE statement in SQL is a flexible tool for implementing conditional logic within queries, similar to IF-THEN-ELSE constructs in programming languages. The ORDER BY clause in SQL is used to sort the results of a query based on one or more columns, enhancing data readability and analysis.
