To add a new column to an existing table in MySQL and assign values to it, you can use the ALTER TABLE statement along with the UPDATE statement.

Here are the specific steps:

  1. Change the structure of a table
  2. your table
  3. freshly created column
ALTER TABLE your_table ADD COLUMN new_column INT;

This will add an integer type column field named new_column to the table.

  1. Update (noun)
  2. fresh column
UPDATE your_table SET new_column = 10;

This will set the values of all rows in the new_column column to 10.

Note: If you only want to set values for specific rows, you can add a suitable WHERE clause in the UPDATE statement to filter the rows.
