    Hi NN,

    In Azure Data Studio, you can change column numeric values using SQL queries by performing an UPDATE statement on your target table. Here's the basic syntax:

    UPDATE your_table_name SET your_column_name = new_value WHERE condition;

    Replace your_table_name with the name of your table, your_column_name with the name of the column you want to update, new_value with the new numeric value you want to set, and condition with the condition that specifies which rows to update (if you want to update specific rows).

    Here's an example that demonstrates how to update the values in a numeric column called quantity in a table named products:

    UPDATE products SET quantity = 10 WHERE category = 'Electronics';

    This query would update the quantity column to 10 for all rows where the category is 'Electronics'.

    Remember to be cautious when using UPDATE statements, especially without a proper WHERE clause, as it can update a large number of rows if not used carefully. It's recommended to make a backup or work with a sample dataset when experimenting with such operations.

    I hope this helps with your query, if you have any questions please let me know.

    Hello,

    You can use theses examples to change column numeric value using sql queries :

    -- Update all rows
    UPDATE Products
    SET Price = 20;
    -- Update rows where the condition is met
    UPDATE Products
    SET Price = 30
    WHERE ProductID = 1;
    -- Increment by 5
    UPDATE Products
    SET Price = Price + 5;
    -- Decrement by 2
    UPDATE Products
    SET Price = Price - 2;
    -- Multiply by 2
    UPDATE Products
    SET Price = Price * 2;
    -- Divide by 2
    UPDATE Products
    SET Price = Price / 2;
    

    Hope this helps

    Regards
