Question
For relation having schema as follows:Student(rollno number, name varchar2, address varchar2, age number, regno number)Which of the following is the correct way to create a table in the database?*1 pointcreate table student(rollno number[6], name varchar2[20], address varchar2[20], age number[3], regno number[10])create table student(rollno number[6], name varchar2[20], address varchar2[20], age number[3], regno number[10]);create table Student(rollno number[6], name varchar2[20], address varchar2[20], age number[3], regno number[10])None of the above
Solution
The correct way to create a table in the database, according to the schema provided, is:
create table student(rollno number(6), name varchar2(20), address varchar2(20), age number(3), regno number(10));
Please note that the square brackets [] are replaced with parentheses () in the data types. Also, SQL is not case sensitive, so 'student' and 'Student' are considered the same. However, it's a good practice to keep the table name in lower case for consistency.
