CREATE TABLE command is a part of the DDL (Data Definition Language) set of commands in MySQL and it allows a user to create a new table for the given database.
a) Unquoted names can consist of any characters in the SQL Server default character set with an exception that not all the characters can be digits. For example, ‘23test’ is a valid table name but not ‘2345’.
Column definition: A table in SQL must consist of at least one column. All the column definitions must consist of column_name as well as the column data type. You can also optionally include the other column properties like primary key, null, not null, etc.
b) Table and database names can be quoted with a backtick character (`) and can contain any letter/character except the backtick character itself. With the quoted names you can even have table/database names having all digits.
As discussed in the previous sections, in MySQL a table is always in context with the database of which it is a part of. Hence in order to access a table, you can use a fully qualified table name – which is nothing but the combination of database name separated by a period and then the column name.
