How can an incremental value be added to an existing value in the same table?

edit

To add an incremental value to an existing value in the same table, you can use an UPDATE statement with the SET clause and the addition operator (+) to update the column value. Here's an example SQL query:

UPDATE my_table
SET my_column = my_column + incremental_value
WHERE some_condition = some_value;

In this query, my_table is the name of the table you want to update, my_column is the name of the column you want to update, and incremental_value is the value you want to add to the existing value in my_column. You can also specify a condition in the WHERE clause to update only the rows that match the condition.
