各位前輩先進你們好，遇到一個問題想請教
現有一MS SQL資料表a111
MKDAT=生產日期 (中華民國曆)
ORDER_NO=訂單號碼
MKQTY=生產數量
我想求出以查詢日前13個月的訂單生產量每個級距共有多少筆的級距表
1.每月500 pc以下有多少訂單筆數 (COUNT)
2.每月501~1000pc(含)有多少訂單筆數 (COUNT)
3.每月1000 pc以上有多少訂單筆數 (COUNT)
4.每月共有多少訂單筆數 (COUNT)
5.前12個月共有多少訂單筆數 (COUNT)

我在sqlfiddle將資料表建立後，求上1~5點

問題敘述寫 13個月
但第五題寫 12個月
前面四題沒寫期間，當作要找 13個月的資料，因此會有 13筆資料
第五題是算12個月總筆數，因此只有一筆
http://sqlfiddle.com/#!18/beacd/112 => DEMO
SQL :
DECLARE @M13 varchar(6)
SET @M13 = CONVERT(varchar(6),DATEADD(MONTH,-12,GETDATE()),112) - 191100

SELECT PMM,
COUNT(CASE WHEN MKQTY BETWEEN 0 AND 500 THEN 1 END) '500 pc以下',
COUNT(CASE WHEN MKQTY BETWEEN 501 AND 1000 THEN 1 END) '501~1000pc(含)',
COUNT(CASE WHEN MKQTY > 1000 THEN 1 END) '1000 pc以上',
COUNT(*) '每月訂單筆數'
FROM a1111 where PMM >= @M13
GROUP BY PMM;

DECLARE @M12 varchar(6)
SET @M12 = CONVERT(varchar(6),DATEADD(MONTH,-11,GETDATE()),112) - 191100

SELECT count(MKQTY) AS '筆數'
FROM a1111
WHERE PMM >= @M12;

A .以查詢日前13個月 =>13個月 ?
B .5.前12個月 =>前12個月 ?
不一樣嗎 ?
請附上預期的結果

請用 http://sqlfiddle.com/ 把你的測試資料表跟查詢句都做一份線上測試版，SAVE後把網址貼上來，大家比較方便解答，記得選SQL版本

你在尋找 condition aggregate function.可以使用CASE WHEN搭配你的條件.

SELECT PMM,
       COUNT(*) '總訂單筆數',
       COUNT(CASE WHEN MKQTY <= 500 THEN 1 END) '500 pc以下',
       COUNT(CASE WHEN MKQTY BETWEEN 501 AND 999 THEN 1 END) '501~1000pc(含)',
       COUNT(CASE WHEN MKQTY >= 1000 THEN 1 END) '1000 pc以上',
       COUNT(CASE WHEN [PMM] >= 10907 THEN 1 END) '前12個月'
FROM a1111
GROUP BY PMM

dbfiddle

Note 我建議你前12個月資料判斷使用另一個Date的欄位
