错误代码：1136。列计数与第 1 行的值计数不匹配，为什么？

Question

USE Airline;

CREATE TABLE Responsible_for(
Time_work TIME NOT NULL,
date_work DATE NOT NULL,
Staff_ID INT NOT NULL,
Passenger_ID VARCHAR(45) NOT NULL,
 CONSTRAINT FOREIGN KEY(Passenger_ID) REFERENCES Passenger(Passenger_ID),
 CONSTRAINT FOREIGN KEY(Staff_ID) REFERENCES Staff(Staff_ID));

SELECT * FROM airline.Responsible_for;
INSERT INTO  Responsible_for VALUES(
    ('04:00:00','2019-04-01',1235,'1102546778'));

why there is error? thank you

Answer 1

You have an additional pair of parentheses around the list of values that should not be there.

That should be:

INSERT INTO Responsible_for(time_work, date_work, staff_id, passenger_id) 
VALUES ('04:00:00','2019-04-01',1235,'1102546778');

Notes:

• it is a good practice to always enumerate the columns to insert ; this prevents hard-to-debug issues, and can make the code resilient to changes in the structure of the target table

• you use airline at the beginning of the script, so there is no need to prefix the table name with the schema name in the insert statement

• I would recommend against storing the date and time components in separate columns; this makes things unnecessarily complicated (and less efficient) when you need to compare it against a datetime; MySQL has the datetime datatype, that is meant to store both together
