    • Every column in a table has COLUMN_ID. If you have two columns in a table and need to add one more. Newly added will have COLUMN_ID next to last created column. i.e. if last column_id was 2, newly added will have column_id 3. That’s why you cannot create a column in between existing one. And for this you have to drop and recreate you table, with new column sequence. Sql Server Management Studio work in a same way i.e. recreates your table.
