I have the following table in SQL Server 2008:
CREATE TABLE tbl (ID INT, dtIn DATETIME2, dtOut DATETIME2, Type INT)
INSERT tbl VALUES
(1, '05:00', '6:00', 1),
(2, '05:00', '7:00', 1),
(3, '05:01', '8:00', 1),
(4, '05:00', '8:00', 1),
(5, '05:00', '6:00', 2),
(6, '05:00', '7:00', 2)
that selects IDs of all records of the same type, with the same dtIn date, ordered by stOut in ascending order:
SELECT DISTINCT tbl.id FROM tbl
LEFT JOIN tbl AS t1
ON tbl.type = t1.type AND
tbl.dtIn = t1.dtIn
ORDER BY tbl.dtOut ASC
But it gives me an error:
ORDER BY items must appear in the select list if SELECT DISTINCT is specified
I tried putting that ORDER BY in different places and it all doesn't seem to work. What am I doing wrong here?
