Correcting SQL for EVENT Table Creation

CREATE TABLE EVENT ( EventName VARCHAR2(100) NOT NULL, VenueName VARCHAR2(100) NOT NULL, CONSTRAINT EventPK PRIMARY KEY (EventName), CONSTRAINT VenueFK FOREIGN KEY (VenueName) REFERENCES STUDENT(VenueName), CONSTRAINT EventPK FOREIGN KEY (EventName) REFERENCES STUDENT(EventName) );

It looks like you're trying to create a table named EVENT with some constraints, but there are a few issues in your SQL statement. Specifically, you are trying to create foreign key constraints that reference the STUDENT table, but the STUDENT table is not defined in your statement. Additionally, you cannot have two constraints with the same name (EventPK is used for both the primary key and one of the foreign keys).

Here’s a corrected version of your SQL statement, assuming that the STUDENT table exists and has the appropriate columns:

CREATE TABLE EVENT (
    EventName VARCHAR2(100) NOT NULL,
    VenueName VARCHAR2(100) NOT NULL,
    CONSTRAINT EventPK PRIMARY KEY (EventName), 
    CONSTRAINT VenueFK FOREIGN KEY (VenueName) REFERENCES STUDENT(VenueName),
    CONSTRAINT EventFK FOREIGN KEY (EventName) REFERENCES STUDENT(EventName)
);

Key Changes:

1. Unique Constraint Names: Changed the second EventPK to EventFK to avoid naming conflicts.
2. Assumption of STUDENT Table: This assumes that the STUDENT table exists and has columns VenueName and EventName that can be referenced.

Additional Considerations:

• Ensure that the STUDENT table is created before you create the EVENT table.
• If EventName and VenueName in the STUDENT table are not meant to be foreign keys, you may need to adjust the foreign key constraints accordingly.
• If you want to enforce that VenueName must exist in the STUDENT table, ensure that the STUDENT table has a corresponding VenueName column.
