i have a user table which consists of property 'user_id' (primary key), 'first_name' and 'last_name'. i have another service table which consists of 'service_id' (primary key) and 'user_info'. is it possible for me to insert the all data collected in user table (last_name and first_name) to a single column 'user_info' in service table?

i dont know why u want to do such a thing other than going for an association . you can use the first name + last name manually on the service table . but an association seems much reliable
