Create a function which takes in a vowel and returns a table containing all of the categories, countries and continents which contain that vowel:
The top 4 results when you run your function using the vowel I as input, for example.
The function will need one parameter to take in the vowel and a table variable to store the output from each separate select.
CREATE FUNCTION NameGoesHere
(@Para1 datatype)
RETURNS @TableName TABLE
(Column 1 datatype
,Column 2 datatype)
AS
BEGIN
INSERT INTO @TableName
--SELECTS GO IN HERE
INSERT INTO @TableName
--SELECTS GO IN HERE
INSERT INTO @TableName
--SELECTS GO IN HERE
RETURN
END
If you call your function once for each vowel within a SELECT statement, you could display the results for each vowel:
A shock result - E wasn't the most common vowel.
Optionally save this as Vowel please bob.sql and close it down.
