I have question I have Column in My table Revenue , Cost , Order_Type,

I have condition IF Order_Type = 'Success' Then (Revenue - Cost) should display
And if Order_ type Contains 'Return' then (Revenue * -1) and (Cost * -1) should display AS Margin
How i do that can any one help In SQL.

Note - Order_type Have multi-pal Return type like UAE-Return, AE-Return, XYZ-Return like this i just want If Order_Type contains Return value then Above condition should work.

What I have tried:

Declare @OrderType Varchar(Max) = 'Return'



IF CHARINDEX ('Return',@OrderType)> 0
Begin 
Select Revenue * -1 & Cost * -1 ,Sales_Man,Order_Date,Order_Type
From ERP_Source_Table
END
ELSE 
Begin
Select Revenue - Cost 
From ERP_Source_Table
END
 
 Select * from ERP_Source_Table

Do you mean like this:

SQL

DECLARE @OrderType VARCHAR(MAX) = 'Returns'
IF @OrderType = 'Success' 
   SELECT Revenue - Cost FROM MyTable
ELSE IF @OrderType = 'Return'
   SELECT Revenue * -1, Cost * -1 FROM MyTable
ELSE
   SELECT * MyTable

DECLARE @OrderType VARCHAR(MAX) = 'AE-Return'
IF @OrderType = 'Success'
Select Revenue - Cost From ERP_Source_Table
ELSE IF CHARINDEX ('Return',@OrderType) > 0
Select Revenue * -1 , Cost * -1 ,Sales_Man,Order_Date,Order_Type From ERP_Source_Table
ELSE
Select * from ERP_Source_Table

To be precise!
