How to add a column to a specific location in a SQL table

In SQL, you can use the ALTER TABLE statement to add a column to a table and specify its location in an existing column.

step:

1. Use ALTER TABLE statement to start the query.
2. Specifies the table name to be modified.
3. Use the ADD COLUMN clause to define the new column to be added.
4. Specifies the name, data type, and any other constraints for the new column.
5. Use the AFTER clause to insert a new column after an existing column.

grammar:

 <code>ALTER TABLE table_name ADD COLUMN new_column_name data_type AFTER existing_column_name;</code>

Example:

Suppose we have a table called employees with id , name and salary columns. Now we need to add a column called department between name and salary columns.

 <code>ALTER TABLE employees ADD COLUMN department VARCHAR(50) AFTER name;</code>

After executing this query, the employees table will look like this:

id	name	department	Salary
1	John Doe	Sales	50000
2	Jane Smith	Marketing	45000
3	Michael Jones	IT	60000
