Hi guys

gota a quick question

ok.. lets say.. i have mysql database.. and in that database.. i gota table .. in that table i got a primary key seq_id which is int.. and then i got another table.. and it also has the same key seq_id which is int as well.. and i got data in that table.. now lets say if i wanna change the type from int to char.. will it affect .. my data?

thanks in advance

Yes you may, no data affected but you must convert from int to varchar...
