Update a column with MIN date grouping by ID
Hey guys,
I have a table with some fields:
I would like to UPDATE MyMinDateTime with the MIN(MyDate) value grouping by MyID.
The expected result would be:
For MyID=1 MyMinDateTime=2018-10-24 15:39:00.000
For MyID=2 MyMinDateTime=2018-10-23 20:39:00.000
For MyID=3 MyMinDateTime=2019-10-24 20:39:00.000
Can't seem to figure out the best way to do this. Any help will be greatly appreciated.
Thanks!
I have a table with some fields:
DROP TABLE #tbl_WithSomeFields
CREATE TABLE
#tbl_WithSomeFields (
MyID VARCHAR(255)
,MyPID VARCHAR(20)
,MyOtherThing VARCHAR(100)
,MyOtherOtherThing VARCHAR(10)
,MyDate DATETIME
,MyMinDateTime DATETIME
);
INSERT INTO
#tbl_WithSomeFields (MyID, MyPID, MyOtherThing, MyOtherOtherThing, MyDate, MyMinDateTime)
VALUES
('1', '1234567', 'A', '12C', '2018-10-24 20:39:00', ''),
('1', '1234567', 'A', '11C', '2018-10-24 15:39:00', ''),
('2', '1234567', 'A', '12B', '2018-10-23 20:39:00', ''),
('2', '1234567', 'A', '13D', '2018-10-24 20:39:00', ''),
('3', '1234567', 'A', '8', '2019-10-24 20:39:00', '');
