MySQL Delete语句

我正在创建一个数据库，使用MYSQL并插入了数据。但是，当我尝试删除一行时，我没有运气。有人能帮我理解为什么该行不删除吗？我已经为创建的表提供了insert语句和delete语句，请记住，该表显示为已满

 CREATE TABLE IF NOT EXISTS `new_schema2`.`Employee` (
  `EID` INT NOT NULL,
  `Fname` VARCHAR(45) NOT NULL,
  `Lname` VARCHAR(45) NOT NULL,
  `AddressID` INT NOT NULL,
  `PayLevel` Decimal NOT NULL,
  `Jobtitle` VARCHAR(45) NOT NULL,
  `DateofEmployment` DATE NOT NULL,
  PRIMARY KEY (`EID`))
ENGINE = InnoDB;

#Inserts begin Here
INSERT INTO new_schema2.Employee 
       (EID, Fname, Lname, AddressID, PayLevel, Jobtitle, DateofEmployment) 
       VALUES 
   (    0,'Andrew','Wiggins','7', 10000.00,'Stock Boy','08/11/12' );

INSERT INTO new_schema2.Employee 
       (EID, Fname, Lname, AddressID, PayLevel, Jobtitle, DateofEmployment) 
       VALUES 
       (1,'Andrew','Wiggins','7', 10000.00,'Stock Boy','08/11/12' );

INSERT INTO new_schema2.Employee  
       (EID, Fname, Lname, AddressID, PayLevel, Jobtitle, DateofEmployment) 
       VALUES 
       ('2','Nick','Smith','8', 20000.00,'Cashier','08/10/09' );


 INSERT INTO new_schema2.Employee 
       (EID, Fname, Lname, AddressID, PayLevel, Jobtitle, DateofEmployment) 
       VALUES 
       ('3','Niko','Jackson','9',40000.00,'Manager','05/10/06' );

INSERT INTO new_schema2.Employee 
       (EID, Fname, Lname, AddressID, PayLevel, Jobtitle, DateofEmployment) 
       VALUES 
       ('4','Dante','Henderson','10', 20000.00,'Cashier','06/15/09' );

INSERT INTO new_schema2.Employee 
       (EID, Fname, Lname, AddressID, PayLevel, Jobtitle, DateofEmployment) 
       VALUES 
       ('5','Jessica','Smith','8',22000.00,'Performer','08/09/11' );

INSERT INTO new_schema2.Employee 
       (EID, Fname, Lname, AddressID, PayLevel, Jobtitle, DateofEmployment) 
       VALUES 
       ('6','Alex','Grossi','15',100000.00,'Owner','08/11/02' );

#Delete statements begin here
DELETE FROM new_schema2.employee
WHERE EID = 0 AND Fname='Andrew' AND Lname='Wiggins' AND AddressID='7' AND  DateofEmployment='11/12/08'  AND PayLevel='10000.00'AND  Jobtitle = 'Stock Boy';

您不需要指定删除中的所有列

就用这个

   DELETE FROM new_schema2.employee
   WHERE EID = 0 

---

其未删除的原因是其日期条件失败

你有场吗

`DateofEmployment` DATE NOT NULL

当您在MySQL中插入

08/11/12

时，它将变成

2008-11-12

因此，delete命令应为

DELETE FROM Employee
WHERE EID = 0 
AND Fname='Andrew' 
AND Lname='Wiggins' 
AND AddressID='7' 
AND  DateofEmployment='2008-11-12'  
AND PayLevel='10000.00'
AND Jobtitle = 'Stock Boy';

核对

SELECT DateofEmployment FROM Employee

看看数据是如何显示的，你会自己得到答案。
