When it comes to handling conditional logic in SQL, developers have long debated the merits of two prominent approaches: the traditional if-else method and the powerful CASE statement
Are you a staunch supporter of if-else or an advocate for the versatility of CASE?
Logic 1: Using If-Else Statment
CREATE PROCEDURE FlagOrderPriority
    @OrderID INT,
    @OrderValue DECIMAL(10, 2)
AS
BEGIN
    SET NOCOUNT ON;
    DECLARE @Priority VARCHAR(20);
    IF @OrderValue > 30
        SET @Priority = 'Big Customer Order';
    ELSE IF @OrderValue >= 10 AND @OrderValue <= 30
        SET @Priority = 'Medium Order';
    ELSE
        SET @Priority = 'Low priority order';
    -- Log the order priority
    INSERT INTO OrderLog (OrderID, Priority)
    VALUES (@OrderID, @Priority);
END;
Logic 2: Using Case Statement
CREATE PROCEDURE FlagOrderPriority
    @OrderID INT,
    @OrderValue DECIMAL(10, 2)
AS
BEGIN
    SET NOCOUNT ON;
    DECLARE @Priority VARCHAR(20);
    SET @Priority = CASE
        WHEN @OrderValue > 30 THEN 'Big Customer Order'
        WHEN @OrderValue >= 10 AND @OrderValue <= 30 THEN 'Medium Order'
        ELSE 'Low priority order'
    END;
    -- Log the order priority
    INSERT INTO OrderLog (OrderID, Priority)
    VALUES (@OrderID, @Priority);
END;
