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 namedStaff.Email VARCHAR(200) NOT NULL: This defines a column namedEmailwith a data type ofVARCHARand a maximum length of 200 characters. TheNOT NULLconstraint ensures that theEmailfield cannot contain NULL values.Name VARCHAR(255) NOT NULL: This defines a column namedNamewith a data type ofVARCHARand a maximum length of 255 characters. TheNOT NULLconstraint ensures that theNamefield cannot contain NULL values.CONSTRAINT PK_Email PRIMARY KEY (Email): This adds a constraint to the table, naming itPK_Email, and sets theEmailcolumn as the primary key for the table. The primary key constraint ensures that each value in theEmailcolumn 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)
);
