Concatenating data
Assembling a string from parts is done quite often in SQL Server. You may need to put together information from different columns and send the result as a whole to different applications. In this exercise, you will get familiar with the different options for concatenating data.
You will create a message similar to this one: "Chocolate with beans from Belize has a cocoa percentage of 0.6400".
The sentence is created by concatenating two string variables with data from the columns bean_origin and cocoa_percent, from the ratings table.
For restricting the number of results, the query will select only values for the company called "Ambrosia" and bean_type is not unknown.
