My three minute practice teaching video on Filtering in SQL taken from the Database and SQL Lesson. I used IShowU to record it but somehow managed to set the recording so it clipped the left hand character from the video.
The video is posted on YouTube.
As discussed in the last group call, I used a couple of ‘invisible keystrokes’ and based on feedback from others in my group I should have been clearer about how I was achieving some of the results (e.g. use of up arrow to get previous command, use of ‘ctrl+L’ on Mac to clear the screen).
