How can I implement a conditional statement in a SQL SELECT query to return different values based on certain conditions?

Hey everyone! I’m working on a project where I need to analyze some sales data, and I’m stuck on implementing a conditional statement in my SQL SELECT query.

Here’s the scenario: I’ve got a table called `Orders` that has columns for `OrderID`, `OrderAmount`, and `OrderDate`. I want to create a new column in my query that categorizes the orders as ‘High’, ‘Medium’, or ‘Low’ based on the `OrderAmount`.

– If the `OrderAmount` is greater than $500, I want it to be labeled ‘High’.
– If it’s between $200 and $500, I want it to be ‘Medium’.
– And if it’s less than $200, it should be ‘Low’.

I’m not sure how to write this condition in my SELECT query. Can anyone help me with the correct syntax to implement this? Thanks in advance!

      Answer to Your SQL Query Problem

      Hello! I understand your confusion regarding implementing conditional statements in SQL. You can achieve your desired output using the CASE statement in your SELECT query. Below is an example of how you can write your query to categorize the orders based on the `OrderAmount`:

              SELECT 
            OrderID, 
            OrderAmount, 
            OrderDate,
            CASE 
                WHEN OrderAmount > 500 THEN 'High'
                WHEN OrderAmount BETWEEN 200 AND 500 THEN 'Medium'
                ELSE 'Low' 
            END AS OrderCategory
        FROM 
            Orders;

      This query selects the `OrderID`, `OrderAmount`, and `OrderDate` columns from your `Orders` table and adds a new column called `OrderCategory` that classifies the orders based on the amount. The CASE statement checks the `OrderAmount` and assigns the appropriate label.

      I hope this helps with your project! If you have any more questions, feel free to ask.

      SQL Conditional Statement for Order Categorization

      Hi!

      To achieve your goal of categorizing `OrderAmount` in your SQL query, you can use the CASE statement. Here’s how you can write your SELECT query:

      SELECT 
    OrderID,
    OrderAmount,
    OrderDate,
    CASE 
        WHEN OrderAmount > 500 THEN 'High'
        WHEN OrderAmount >= 200 AND OrderAmount <= 500 THEN 'Medium'
        ELSE 'Low'
    END AS OrderCategory
FROM Orders;

      This query will create a new column called OrderCategory, which will contain ‘High’, ‘Medium’, or ‘Low’ based on the conditions you specified for OrderAmount.

      Hope this helps you out!

      To implement the conditional statement you’re looking for in your SQL SELECT query, you can use the CASE statement. This allows you to create a new column that categorizes the `OrderAmount` based on your specified criteria. Here is an example of how your query might look:

      SELECT OrderID, OrderAmount, OrderDate,
       CASE 
           WHEN OrderAmount > 500 THEN 'High'
           WHEN OrderAmount BETWEEN 200 AND 500 THEN 'Medium'
           ELSE 'Low'
       END AS OrderCategory
FROM Orders;

      This query will generate a new column called `OrderCategory` that will contain the labels ‘High’, ‘Medium’, or ‘Low’ based on the `OrderAmount` for each row returned from the `Orders` table. Be sure to adjust the conditions based on your actual thresholds, and this should successfully categorize your sales data.
