Solution
Here are the DDL statements to create the tables as per your requirements:
- Create the DRUG table:
CREATE TABLE DRUG (
DRUG_ID NUMBER PRIMARY KEY,
DRUG_NAME VARCHAR2(100) NOT NULL,
ACTIVE_INGREDIENT VARCHAR2(100) NOT NULL,
CATEGORY VARCHAR2(50) NOT NULL
);
- Create the BATCH table:
CREATE TABLE BATCH (
BATCH_ID NUMBER PRIMARY KEY,
DRUG_ID NUMBER NOT NULL,
BATCH_NUMBER VARCHAR2(50) NOT NULL,
PRODUCTION_DATE DATE NOT NULL,
QUANTITY NUMBER NOT NULL,
CONSTRAINT FK_DRUG_ID FOREIGN KEY (DRUG_ID) REFERENCES DRUG(DRUG_ID),
CONSTRAINT CK_QUANTITY CHECK (QUANTITY > 0)
);
- Create the SHIPMENT table:
CREATE TABLE SHIPMENT (
SHIPMENT_ID NUMBER PRIMARY KEY,
BATCH_ID NUMBER NOT NULL,
SHIPMENT_DATE DATE NOT NULL,
DESTINATION VARCHAR2(255) NOT NULL,
QUANTITY_SHIPPED NUMBER NOT NULL,
CONSTRAINT FK_BATCH_ID FOREIGN KEY (BATCH_ID) REFERENCES BATCH(BATCH_ID),
CONSTRAINT CK_QUANTITY_SHIPPED CHECK (QUANTITY_SHIPPED > 0)
);
These statements will create the tables with the specified constraints. The foreign key constraints ensure that each batch is associated with a specific drug and each shipment is linked to a specific production batch. The check constraints ensure that the QUANTITY and QUANTITY_SHIPPED columns have positive values.
