sql

SQL Server 2005에는 프로덕션에 넣은 모든 코드를 나열하는 cm_production 테이블이 있습니다. 테이블에는 ticket_number, program_type 및 program_name 및 push_number가 다른 열과 함께 있습니다.

목표 : 모든 DISTINCT 프로그램 이름을 프로그램 유형 및 푸시 번호로 계산

내가 지금까지 가지고있는 것은 :

DECLARE @push_number INT;
SET @push_number = [HERE_ADD_NUMBER];

SELECT DISTINCT COUNT(*) AS Count, program_type AS [Type]
FROM cm_production
WHERE push_number=@push_number
GROUP BY program_type

이것은 저를 거기에 데려다 주지만 별개의 이름이 아닌 모든 프로그램 이름을 세는 것입니다 (이 쿼리에서 예상하지는 않습니다). 별개의 프로그램 이름을 선택하지 않고 계산하는 방법을 내 머리에 감쌀 수는 없습니다. 또는 뭔가.

SELECT COUNT(DISTINCT program_name) AS Count,
  program_type AS [Type]
FROM cm_production
WHERE push_number=@push_number
GROUP BY program_type

SELECT Region, count(*)
FROM item
WHERE Region is not null
GROUP BY Region

Region, count
Denmark, 4
Sweden, 1
USA, 10

SELECT COUNT(*)
FROM (SELECT DISTINCT column1,column2
      FROM  tablename
      WHERE condition ) as dt

SELECT COUNT(DISTINCT program_name) AS Count, program_type AS [Type]
FROM cm_production
WHERE push_number=@push_number
GROUP BY program_type

SELECT
    COUNT(program_name) AS [Count],program_type AS [Type]
    FROM (SELECT DISTINCT program_name,program_type
              FROM cm_production
              WHERE push_number=@push_number
         ) dt
    GROUP BY program_type
