我有一个包含字段的销售表：产品、日期、数量。我需要像这样以每日格式提取产品明智销售
Product 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 .............. 31 Total Sale
Rice X X X X X X X X X XX XX XX XX XX XX XX............... XX
Tea X X X X X X X X X XX XX XX XX XX XX XX............... XX
有没有人知道如何做到这一点。
您将不得不使用PIVOT，我在这里最多只放了 6 天，最多包括 31
WITH base AS (
SELECT product, day(date) AS DAY, sum(qty) AS tot
FROM product GROUP BY product, date)
SELECT product, [1], [2], [3], [4], [5], [6]
FROM base pivot(sum(tot) FOR DAY IN ([1],[2],[3],[4],[5],[6])) as tot;
这是你想要的吗？
SELECT PRODUCT, T_DATE,SUM(QTY)
FROM (SELECT PRODUCT, TRUNC(DATE) T_DATE,QTY
FROM TABLE_NAME)
GROUP BY PRODUCT, T_DATE
ORDER BY PRODUCT
尝试 -：
DECLARE @cols1 NVARCHAR(MAX);
DECLARE @cols2 NVARCHAR(MAX);
DECLARE @sql NVARCHAR(MAX);
DECLARE @myDate DATE;
DECLARE @dNum AS INT;
SET @myDate = '2013-01-01'
SET @dNum = DATEDIFF(DAY, DATEADD(DAY, 1-DAY(@myDate), @myDate), DATEADD(MONTH, 1, DATEADD(DAY, 1-DAY(@myDate), @myDate)))
DROP TABLE ##tttt;
CREATE TABLE ##tttt (

我已经在 ADVENTUREWORKS 数据库上对其进行了测试。我使用了以下查询：

您可以在 oracle 中使用以下语句
SELECT
