Multiple COUNT SELECTS from the same table in one query

Question

For some people it might look very simple, but I just simply can\'t get it.
I have multiple MS-SQL SELECT queries from the same table over and over:

Answer 1

You can use a GROUP BY Page

SELECT
  Page
, COUNT(Page) as "nb"
FROM someTable
GROUP BY Page

You can also do a GROUP BY CASE...

SELECT
  CASE
    WHEN Page LIKE '%AEC%' THEN "AEC"
    WHEN Page LIKE '%TOL%' THEN "TOL"
    ELSE ""
  END AS "type"
, count(Page) as "nb"
FROM someTable
GROUP BY type

You can also COUNT IF

SELECT
  COUNT(IF(Page LIKE '%AEC%', 1, NULL) THEN "AEC"
, COUNT(IF(Page LIKE '%TOL%', 1, NULL) THEN "TOL"
FROM someTable
