🚀 Step-by-Step SQL Assignment Execution (Oracle Live SQL)
In this post, I am sharing my DBMS SQL Assignment execution using Oracle Live SQL.
I have included explanations and screenshots for each step to make the process clear and easy to follow.
1️⃣Create Faculty Table (DDL)
The first task was to create a Faculty table with the following fields:
FacultyID – Primary Key
FacultyName – Not Null
Dept – Department name
Email – Unique constraint

2️⃣Insert Students Data (DML)
Next, I inserted three students into the Students table, each belonging to different departments.

3️⃣Alter Table – Add Phone Number
I modified the Students table to add a new column PhoneNo.
This column ensures that phone numbers are 10 digits long.

4️⃣Define Constraints on Courses Table
The Courses table was updated with a constraint to make sure that Credits cannot be less than 1 or more than 5.

5️⃣SELECT with Functions
I displayed the student names in uppercase and also calculated the length of their email IDs.
