    Hello I have doubt at 9:00 of this lecture whole we are modifying the datatype so the value entered already are in int so it doesn’t affect it??
    For example we modified id to varchar and the already existing data in id contain numbers so how it doesn’t affect??

    Hey i have a doubt , you have told earlier that we will use semi colon in the last sentence only but when u have shown the implementation , u have given semi colon after each command after create table , then alter table add column command and then drop column command also .
    Could u please specify the use of semi colons again and again ?
    Also please clarify the use of brackets in the syntax of the commands and not using the same brackets in the actual command when we write . How so ? Those brackets thing is really confusing me

      When he told earlier it was in the case of create table where u are giving all specifications of the table.The whole thing he wrote there was an entire SQL command.The ; is mandatory when u finish the whole command.Here sir is giving separate commands for each task he performs so he provided ; in each of them in the end.As the create table command is very long and these are short that's where u got confused.Don't worry, just remember that the ; always comes at the end of each command.
