Question

Answer 1

You can use :

SELECT SUBSTRING_INDEX('TACOMA, Washington, 98477', ',', 2)

You can read more here.

And the update statement :

UPDATE my_table
    SET my_col = SUBSTRING_INDEX(my_col, ',', 2)

Where you need to replace my_table with your table name and my_col with the column you need to be updated.
