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

Suppose you have a Employee table with these columns Employee_ID, Emp_Name,Emp_Email initially. Later you decide to add Emp_Department column to this table. To enter values to this column, you can use the following query :

Update *Table_Name* set *NewlyAddedColumnName*=Value where *Columname(primary key column)*=value

Example update TblEmployee set Emp_Department='Marketing' where Emp_ID='101'
