Take a deep breath before doing this exercise!
Create and set the value of a variable to hold the first word of each episode type in the tblEpisode table:
What your variable should be set to contain.
You can use the CHARINDEX function to find the first instance of a space within each episode type, although there are other ways to get at the first word of each entry. You'll need to use DISTINCT or GROUP BY to show only one value for each episode type.
Separately, write a query to show the first word of each episode type, along with the episode's doctor name and id, and pivot this to show the following:
The number of episodes by doctor, for Normal and Christmas editions.
Since it would be tedious writing the episode types out longhand (and they may change in the future) combine your two queries to get a single one using dynamic SQL to show all of the episode types:
The final query should show these results.
Save this query as Hmmm, then close it down.
