表结构



将记录上下两条合并成一行



SQL语句

1.详细记录

SELECT *,DATEDIFF(DAY, K.JYSJ, B.JYSJ) AS TS
FROM (
SELECT B1.YE, B1.JYSJ, ROW_NUMBER() OVER (ORDER BY JYSJ) AS R
FROM (
SELECT A.YE, A.JYSJ
FROM FIXF_SVR_XZHJYMX A
WHERE A.ZHID = '000090000000044076'
AND CAST(LEFT(convert(varchar, A.JYSJ, 120), 10) AS datetime) >= CAST('2016-12-30' AS datetime)
AND CAST(LEFT(convert(varchar, A.JYSJ, 120), 10) AS datetime) <= CAST('2017-12-30' AS datetime)
UNION ALL
SELECT 0, CAST('2017-12-30' AS datetime)
) B1
) K, 
(
SELECT B1.YE, B1.JYSJ, ROW_NUMBER() OVER (ORDER BY JYSJ) AS R
FROM (
SELECT A.YE, A.JYSJ
FROM FIXF_SVR_XZHJYMX A
WHERE A.ZHID = '000090000000044076'
AND CAST(LEFT(convert(varchar, A.JYSJ, 120), 10) AS datetime) >= CAST('2016-12-30' AS datetime)
AND CAST(LEFT(convert(varchar, A.JYSJ, 120), 10) AS datetime) <= CAST('2017-12-30' AS datetime)
UNION ALL
SELECT 0, CAST('2017-12-30' AS datetime)
) B1
) B
WHERE K.R = B.R - 1

2.删除余额和天数为0的记录

SELECT Z.YE, Z.TS

FROM (
SELECT K.YE, DATEDIFF(DAY, K.JYSJ, B.JYSJ) AS TS
FROM (
SELECT B1.YE, B1.JYSJ, ROW_NUMBER() OVER (ORDER BY JYSJ) AS R
FROM (
SELECT A.YE, A.JYSJ
FROM FIXF_SVR_XZHJYMX A
WHERE A.ZHID = '000090000000044076'
AND CAST(LEFT(convert(varchar, A.JYSJ, 120), 10) AS datetime) >= CAST('2016-12-30' AS datetime)
AND CAST(LEFT(convert(varchar, A.JYSJ, 120), 10) AS datetime) <= CAST('2017-12-30' AS datetime)
UNION ALL
SELECT 0, CAST('2017-12-30' AS datetime)
) B1
) K, 
(
SELECT B1.YE, B1.JYSJ, ROW_NUMBER() OVER (ORDER BY JYSJ) AS R
FROM (
SELECT A.YE, A.JYSJ
FROM FIXF_SVR_XZHJYMX A
WHERE A.ZHID = '000090000000044076'
AND CAST(LEFT(convert(varchar, A.JYSJ, 120), 10) AS datetime) >= CAST('2016-12-30' AS datetime)
AND CAST(LEFT(convert(varchar, A.JYSJ, 120), 10) AS datetime) <= CAST('2017-12-30' AS datetime)
UNION ALL
SELECT 0, CAST('2017-12-30' AS datetime)
) B1
) B
WHERE K.R = B.R - 1

) Z

WHERE Z.TS > 0 AND Z.YE > 0
