MySQL错误1452插入数据

Question

I am trying to insert data into a database I have designed, and am receiving an error 1452.

SOLVED.

Answer 1

As far as the error concerned most likely you don't have rows in one or all parent tables ( Customer , Branch , AccountTypes ) with PK values that you're trying to refer to in your INSERT statement ( 1 , "40-20-23" , "Current" accordingly).

Insert these rows first

INSERT INTO Customer (FirstName, ...) VALUES(...);
INSERT INTO Branch (BranchSortCode, ...) VALUES('40-20-23', ...);
INSERT INTO AccountTypes (AccountType, ...) VALUES('Current', ...);
