Here is what I am trying to do. Suppose that I have a table called 'table_1' as follows
id_no | FirstName ------------------------ 1111 | John 2222 | Joe 3333 | Susan 4444 | Eli
Now a want to insert a new field to this table, called 'LastName'. I could use the 'ALTER TABLE' statement to add it to the field. However, that column only has 'NULL'. Then how do I populate this column with the data that I have.
You are most of the way there. After adding the column, you will want to do a set of SQL updates to fill in the data.
