Below is the code that I used to create my table of Customer (I've also created another table for AccountID, and they're currently both empty). CREATE TABLE Customer ( CustomerID NUMBER NOT NULL, AccountID NUMBER(20) NOT NULL, CustomerType VARCHAR(10) NOT NULL, CustomerStatus VARCHAR(10) NOT NULL, CONSTRAINT customer_pk PRIMARY KEY (CustomerID), CONSTRAINT check_customer_status CHECK(CustomerStatus IN ('Ineligible', 'Eligible')), CONSTRAINT check_customer_type CHECK(CustomerType IN ('NonResident', 'Residential')) ); I've attempted to establish foreign key and insert the sample data, but the aforementioned error kept appearing. ALTER TABLE Customer ADD FOREIGN KEY (AccountID) REFERENCES Account(AccountID); INSERT INTO Customer (CustomerID, AccountID, CustomerType, CustomerStatus) VALUES (123485, 227482, 'nonresidential', 'eligible'); Anyway I could fix this?
