More accurately stated… Move a column after some other column

mysql> ALTER TABLE `mytable` MODIFY COLUMN `mycolumn` [mycolumn definition] AFTER `someothercolumn`;

Move a column to the first position

mysql> ALTER TABLE `mytable` MODIFY COLUMN `mycolumn` [mycolumn definition] FIRST;

Actually it could be done in the same query. For example:
ALTER TABLE mytable MODIFY COLUMN mycolumn VARCHAR(1000) AFTER someothercolumn;

If you have data in the column you intend to move (varchar for example) you (may) lose it completely when moving and changing to INT.

Thanks Masao

Thanks!

So basically, if your column is of a type other than INT, you’ll need to remake it the way it was AFTER you move it. For ENUMs, copy-paste
