SQL Join vs Where子句

Question

请任何人解释一下这两个陈述之间有什么区别，

SELECT [EmployeeStats].EmpName, [EmployeeStats].Desiganation,[TeamStats].TLGroupID,
    [TeamStats].[Shift]
FROM [EmployeeStats],[TeamStats]
WHERE [EmployeeStats].TeamID = TeamStats.TeamID

并且

SELECT [EmployeeStats].EmpName, [EmployeeStats].Desiganation [TeamStats].TLGroupID,
    [TeamStats].[Shift]
FROM [EmployeeStats]
INNER JOIN [TeamStats]
ON [EmployeeStats].TeamID=TeamStats.TeamID
