I need to get the results showing below but get stuck. Any helps would greatly appreciate.

IF OBJECT_ID('Tempdb.dbo.#t', 'u') IS NOT NULL
DROP TABLE #t
GO

CREATE TABLE #t
(
LoanId INT NULL,
IsBidAccepted BIT NOT NULL,
RRA VARCHAR(20) NULL,
ConstStartdt DATETIME NULL,
ConstEnddt DATETIME NULL,
rk TINYINT
)
GO

INSERT #t
SELECT 104825, 0, 'mjones', NULL, NULL, 1
UNION ALL
SELECT 104825, 0, 'mjones', NULL, NULL, 2
UNION ALL
SELECT 108335, 0, 'mjones', '10/19/2009', '12/11/2009', 1
UNION ALL
SELECT 108335, 1, 'mjones', '10/19/2009', NULL, 2

UNION ALL
SELECT 105270, 0, 'JPeacock', '08/31/2009', '09/09/2009', 1
UNION ALL
SELECT 105270, 1, 'JPeacock', NULL, NULL, 2
UNION ALL
SELECT 107054, 0, 'shickey', NULL, NULL, 1
UNION ALL
SELECT 105256, 1, 'jdominguez', NULL, NULL, 1
GO

SELECT *
FROM #t;
GO

IsBidAccepted = 0 Not accepted, 1 = accepted.

Business rules: If the multiple LoanId are the same RETURN where IsBidAccepted = 1 and ConstStartdt IS NULL OR ConstEnddt IS NULL
If the multiple loanId are the same RETURN where and IsBidAccepted = 0 and ConstStartdt IS NULL OR ConstEnddt IS NULL

-- Desire results:
LoanId IsBidAccepted RRA ConstStartdt ConstEnddt rk
----------- ------------- -------------------- ----------------------- ----------------------- ----
104825 0 mjones NULL NULL 2
108335 1 mjones 2009-10-19 00:00:00.000 NULL 2
105270 1 JPeacock NULL NULL 2
107054 0 shickey NULL NULL 1
105256 1 jdominguez NULL NULL 1

[code]
SELECT LoanId, IsBidAccepted, RRA, ConstStartdt, ConstEnddt, rk
FROM
(
SELECT ROW_NUMBER() OVER (PARTITION BY LoanId ORDER BY rk DESC) AS Seq, LoanId, IsBidAccepted, RRA, ConstStartdt, ConstEnddt, rk
FROM Table
WHERE ConstStartdt IS NULL OR ConstEnddt IS NULL
)t
WHERE Seq=1
