我想从一个看起来像这样的SQL查询中转出记录......
// instead of
parentCursor.get('mylist').splice(...);
// do:
parentCursor.update('mylist', list => list.splice(...));
到一个看起来像这样的键值对...
FirstName Amount PostalCode LastName AccountNumber
John 2.4 ZH1E4A Fork 857685
我想在SQL中完成所有操作。我查看了枢轴示例,但我不确定它是否适用于此。我知道我可以使用临时表,联合但我希望有一个更优雅的解决方案。有人有建议吗?
谢谢你, 保罗

试试这个:
DECLARE @t table(FirstName varchar(10), Amount money, PostalCode varchar(10),
LastName varchar(10), AccountNumber int)
INSERT @t values('John', 2.4, 'ZH1E4A', 'Fork', 857685)
;WITH CTE AS
(
SELECT
[FirstName],
cast([Amount] as varchar(10)) [Amount],
[PostalCode],
[LastName],
cast([AccountNumber] as varchar(10)) [AccountNumber]
FROM @t
)
SELECT [Key],Value
FROM CTE
UNPIVOT
(Value FOR [Key] IN
([FirstName], [Amount], [PostalCode], [LastName], [AccountNumber]) ) AS unpvt
结果:
Key Value
FirstName John
Amount 2.40
PostalCode ZH1E4A
LastName Fork
AccountNumber 857685
