Hello Folks,

Is it possible to alter a table column , create a new column from the contents of an already existing Column..
e.g
ALTER TABLE `tb_name` ADD `new_column` VARCHAR( 250 ) FROM `tb_name` CHARACTER SET latin1 COLLATE latin1_swedish_ci NOT NULL AFTER `old_column`  but i want all the contents from the old_column to be replicated to the new_column..

Thanks in advance

I don't think so.
You have to run update query after alter table.

Youn need the aletr column to ad new column
andafter that you need to run update statement to move data to new column

Update `tb_name`
set `new_column`  = `old_column`
