I need to select unique records from below table
CREATE TABLE #tb1 (date DATETIME , ref1 nvarchar(50),ref2 nvarchar(50), Name nvarchar(50), amount INT )
INSERT INTO #tb1 VALUES
('2017-01-01 08:00','My Ref1','My Second Ref1', 'Mr. A',500),
('2017-01-01 08:01','My Ref1','My Second Ref1', 'Mr. B',500),
('2017-02-01 08:00','My Ref2','My Second Ref2', 'Mr. A',500),
('2017-02-01 08:02','My Ref2','My Second Ref2', 'Mr. B',500),
('2017-02-01 08:01','My Ref2','My Second Ref3', 'Mr. A',500),
('2017-02-01 08:01','My Ref2','My Second Ref3', 'Mr. B',500),
('2017-03-01 08:01','My Ref5','My Second Ref5', 'Mr. C',500),
('2017-03-01 08:02','My Ref5','My Second Ref5', 'Mr. C',500)
Result i,m expecting is as follows
('2017-01-01 08:00','My Ref1','My Second Ref1', 'Mr. A',500)
('2017-02-01 08:00','My Ref2','My Second Ref2', 'Mr. A',500)
('2017-02-01 08:01','My Ref2','My Second Ref3', 'Mr. A',500)
('2017-03-01 08:01','My Ref5','My Second Ref5', 'Mr. C',500)
('2017-03-01 08:02','My Ref5','My Second Ref5', 'Mr. C',500)
- Each record should have unique ref1 & ref2 ( so i exclude 2, 4 & 6 rows)
- And if same name has multiple records with unique ref1 & ref2, but with different datetime then all such records has to be selected. ( So i select both 7th & 8th Records)
How can i write a select statement for this.
Highly appreciate your help for this..
Thanks
