Column reordering is not supported. If you really need an exact order
you have three choices:
1. Use explicit column names in SELECTs (not SELECT *).
2. CREATE VIEW with column order you desire.
3. Create a new table and populate it with data from old table, then drop
old table and rename the new one.
