OR is not supported with CASE Statement in SQL Server

🎉🔥 Breaking News: OR is Not Supported with CASE Statement in SQL Server! Here's What You Can Do 🔥🎉

So you've stumbled upon the mysterious case of the unsupported OR operator in the WHEN clause of a CASE statement in SQL Server. Fear not, dear reader, for we have the answers you seek! 👀

🚫 The Forbidden OR Operator

Let's start by addressing the issue at hand. SQL Server does not allow the usage of the OR operator directly in the WHEN clause of a CASE statement. This means that you cannot use the OR operator to specify multiple conditions within a single WHEN statement. Cue the sad trombone 🎶.

💡 Creative Workarounds

But hey, don't be disheartened just yet! There are a couple of nifty workarounds you can utilize to achieve the desired result.

1️⃣ Multiple WHEN Statements

Instead of trying to squeeze multiple conditions separated by OR into a single WHEN statement, you can break them down into multiple WHEN statements. Here's an example:

CASE 
    WHEN ebv.db_no = 22978 OR ebv.db_no = 23218 OR ebv.db_no = 23219 THEN 'WECS 9500' 
    ELSE 'WECS 9520' 
END AS wecs_system

By using separate WHEN statements for each condition, you effectively bypass the OR operator limitation. Ta-da! 🎩

2️⃣ In Operator

Another cool trick in your SQL arsenal is the IN operator. This operator allows you to specify multiple values in a single condition, making your code cleaner and more concise. Check it out:

CASE 
    WHEN ebv.db_no IN (22978, 23218, 23219) THEN 'WECS 9500' 
    ELSE 'WECS 9520' 
END AS wecs_system

By leveraging the power of the IN operator, you can neatly group your conditions together like a happy SQL family. 😊👨‍👩‍👧‍👦
