In SQL, How to add values after add a new column in the existing table?

Question

I created a table and inserted 3 rows. Then I added a new column using alter. How can I add values to the column without using any null values?

Answer 1

Why don't you use UPDATE statement:

UPDATE tablename SET column=value <WHERE ...>

WHERE is optional. For instance in T-SQL for table:

I can update column NewTestColumn by this statement:

UPDATE [dbo].[Table] SET [NewTestColumn] = 'Some value'
