How to Change Column Order in DB2

In DB2, when adding a new column, you cannot directly specify the order of the column, as the order of columns in a table is determined by the order in which the table was created. However, you can adjust the order of columns by following these steps:

1. Create a new temporary table and copy the fields from the original table to the temporary table in the desired order one by one.
2. delete the original table
3. Recreate the original table and copy each field from the temporary table back into the original table in the desired order.

Before making any adjustments to the field order, be sure to back up the original table data to prevent data loss.
