mysql - How can i convert a price field which is currently varchar to a decimal so my prices will order correctly? -
i using mysql.
i have varchar field incorrectly used price. ordering of table not work correctly putting on 1000 bottom of list.
i need convert price field in existing populated database varchar decimal guess?
any appreciated.
simply use alter table statement.
if example table called 'products' , field called 'product_price' use:
alter table products modify column product_price double;
nb: anything, i'd tempted make backup of data (via mysqldump) prior performing operation - it'll take seconds , it's better safe rather sorry. :-)
