MULTISET

Example

DECLARE
  TYPE phone_type IS RECORD (
    country_code NUMBER(3),
    area_code NUMBER(3),
    phone_number VARCHAR2(8)
  );
  TYPE phone_table_type IS TABLE OF phone_type;
  phone_table phone_table_type;
BEGIN
  phone_table := phone_table_type(
    phone_type(1, 408, '1234567'),
    phone_type(1, 650, '7654321')
  );
END;

Output

No specific output is displayed as it is a PL/SQL anonymous block.

Explanation

In this example, two user-defined types are declared: a record type phone_type and a table type phone_table_type. In the BEGIN section, two records are inserted into a table phone_table. The phone_table_type tyep enables creation of a table-like structure in PL/SQL block.

Example

CREATE TABLE Patients (
    PatientID int,
    Name varchar(255),
    Allergies nvarchar(max),
);

INSERT INTO Patients (PatientID, Name, Allergies)
VALUES (1, 'John Doe', 'Penicillin, Latex');

Output

(1 row(s) affected)

Explanation

In the above example, a numeric field PatientID, a string field Name, and a MULTISET field Allergies are defined in the Patients table. The MULTISET field is used to store multiple values in a single field. A single row is inserted into the Patients table. The MULTISET field Allergies in the inserted row contains the values 'Penicillin, Latex'.
