Defining Primary Key 1 column as Primary key

Yes, the provided SQL syntax can be used to create a table for staff members in a college with the Email column defined as the primary key. The syntax you provided is correct. Here's a breakdown of the SQL statement:

• CREATE TABLE Staff: This command creates a new table named Staff.
• Email VARCHAR(200) NOT NULL: This defines a column named Email with a data type of VARCHAR and a maximum length of 200 characters. The NOT NULL constraint ensures that the Email field cannot contain NULL values.
• Name VARCHAR(255) NOT NULL: This defines a column named Name with a data type of VARCHAR and a maximum length of 255 characters. The NOT NULL constraint ensures that the Name field cannot contain NULL values.
• CONSTRAINT PK_Email PRIMARY KEY (Email): This adds a constraint to the table, naming it PK_Email, and sets the Email column as the primary key for the table. The primary key constraint ensures that each value in the Email column is unique and not null.

The complete SQL syntax is:

CREATE TABLE Staff (
    Email VARCHAR(200) NOT NULL,
    Name VARCHAR(255) NOT NULL,
    CONSTRAINT PK_Email PRIMARY KEY (Email)
);

This syntax will successfully create the Staff table with Email as the primary key.
