|Parameter||What it should contain|
|@First||The name of an event|
|@Second||The details for an event|
Your function should sum:
Your function should then return this value as an integer. As a reminder, here's the syntax of a basic function:
CREATE FUNCTION NameOfFunction(
Test that your function works by running a query like this:
-- this should return the number 7 (4 + 3)
AS 'Number of letters'
Incorporate this function within a query to list out events in order of the total number of characters used, with the shortest first:
The first few events this query should return.
