关于数据库的连接查询

我在同一个数据库下建立了三个表:
1,表:project

projectId

projectName

2,表:position

positionId

positionName

3,表:work

workId	workprojectId	workpositionId	workAmount	workTime	workStatus	testTime
int	int	int	int	datetime	binary	int

而projectId和position都是work的外键,对应:workprojectId和workpositionId,要取得如下数据:
projectName, positionName, workAmount,workTime,  workStatus, testTime则是如下sql语句(想了老半天,后来在
SQLExpress下查询成功)

SELECT project.projectName, position.positionName, [work].workAmount, [work].workTime,
      [work].workStatus, [work].testTime
FROM position INNER JOIN
      [work] ON position.positionId = [work].workposition INNER JOIN
      project ON [work].workprojectId = project.projectId
