学生对 Coursera Project Network 提供的 SQL Joins 的评价和反馈

There were some issues related to this course such as in the 4th lesson, the employees table didn't have a managerid field for the self join exercise. The instructor also switched her alias syntax method without mentioning anything to her audience. There were other subtle mistakes throughout the course and the explanations and examples could be improved. However, it's a good, simple course to continue expanding your SQL knowledge and work through some exercises. The instructor comes across as capable and intelligent but just needs to clean up the course a bit.

I enjoyed this Project Network! I learned more about the differences of all SQL Joints.

Excellent course, very clear.

short and Easy to understand

it was easy to understand

Beginner friendly..

Great course!

Excellent.

very easy to follow. Definitely recommendable. However some mentioned columns are not available and sometimes instruction for the activity is unclear, but it's okay since there are solution walkthroughs in the end

good for basics
