This is a SQL code that selects a column named "ftp_bucket" from the table "people". It creates different categories of values depending on the conditionals. The categories are based on two attributes of each person: "profile_weight_in_grams" and "profile_ftp".
The code first checks if the weight of the person (in grams) is greater than 10,000. If yes, it calculates the "watts per kilogram" (wkg) value by dividing "profile_ftp" by the weight of the person in kilograms (i.e., "profile_weight_in_grams/1000.0"). If this "wkg" value falls within certain ranges, the code assigns specific labels to the "ftp_bucket" column, such as "<2.5 wkg", "Between 2.5 and 3.2 wkg", and so on. Finally, if no conditions are met, the code assigns "N/A" to the "ftp_bucket" column.
