MySQL查詢，怎么了？

Question

我被要求為數據庫創建查詢，該查詢將創建：顯示名字，姓氏，電子郵件和等級（文本標題）的員工列表，他們的技能中包含單詞“視頻”（一個條目）每個員工，即使員工具有多種視頻技能也是如此）

到目前為止，我已經做到了：

SELECT Employee.FirstName, Employee.LastName, Employee.Email, Grade.Title,
FROM Employee INNER JOIN
     Grade
     ON Grade.GradeID = Employee.GradeID INNER JOIN
     EmployeeSkill
     ON EmployeeSkill.EmployeeID = Employee.EmployeeID INNER JOIN
     Skill
     ON Skill.SkillID = EmployeeSkill.SkillID
WHERE Skill.Title LIKE "%video%"

但是，我一直收到1064錯誤，並且不確定自己在做什么錯，請幫忙。

您的查詢的SELECT部分​​中有一個多余的逗號

    SELECT Employee.FirstName,
           Employee.LastName,
           Employee.Email,
           Grade.Title, -- Remove the comma here 
      FROM Employee
INNER JOIN Grade
        ON Grade.GradeID = Employee.GradeID
INNER JOIN EmployeeSkill 
        ON EmployeeSkill.EmployeeID = Employee.EmployeeID 
INNER JOIN Skill 
        ON Skill.SkillID = EmployeeSkill.SkillID
     WHERE Skill.Title LIKE "%video%"
