试图在这里保存自己的大量数据。我目前有以下输出：
CONTID DESCR
001 Area 1
001 Area 2
001 Area 3
我想做的是为每个＆＃34; DESCR＆＃34;输出7条记录。 （区域），每周一天1（相应地为0 - 6）。
示例输出将是：
CONTID DESCR DAYOFWEEK
001 Area 1 0
001 Area 1 1
001 Area 1 2
001 Area 1 3
001 Area 1 4
001 Area 1 5
001 Area 1 6
001 Area 2 0
001 Area 2 1
001 Area 2 2
001 Area 2 3
001 Area 2 4
001 Area 2 5
001 Area 2 6
001 Area 3 etc...
如果可能的话，我想用直接的SQL做这件事。这是一次性的复制/粘贴＆＃34;填写新表的工作。
答案 0 :(得分：3)
您可以使用CROSS JOIN
执行此操作（Thx to @TT。指出，我的答案会被缩短）
DECLARE @tbl TABLE(CONTID INT, DESCR VARCHAR(100));
INSERT INTO @tbl VALUES
(001,'Area 1')
,(001,'Area 2')
,(001,'Area 3');
SELECT *
FROM @tbl AS tbl
CROSS JOIN (VALUES(0),(1),(2),(3),(4),(5),(6)) AS AllDays(DayInx)
答案 1 :(得分：1)
另外，考虑这个其他解决方案也使用交叉连接，但隐式使用派生表，以便将来需要在其特定RDMS中使用通用SQL解决方案的读者：
