Question

SELECT Id, Value, Sender, Recipient, MIN(DateTime), TypeOf, VideoId, Likes, Comments
FROM xx.dbo.StreamView
WHERE StreamView.TypeOf = 3 AND StreamView.[DateTime] >= "Some DateTime Value Here"

I am trying to get the latest record directly newer than the given DateTime value.

when executing this query I am receiving the following error:

Msg 207, Level 16, State 1, Line 1
Invalid column name 'Some DateTime Value Here'.

Also, when removing this line AND StreamView.[DateTime] >= "Some DateTime Value Here"

I am getting:

Msg 8120, Level 16, State 1, Line 1
Column ‘xx.dbo.StreamView.Id’ is invalid in the select list because it is not contained in either an aggregate function or the GROUP BY clause.

Suggestions? Thanks.

Update

WITH
  sequenced_records AS
(
  SELECT
    ROW_NUMBER() OVER (ORDER BY [DateTime] DESC) AS sequence_id,
    *
  FROM
    xx.dbo.StreamView
  WHERE
    StreamView.TypeOf = 3
    AND StreamView.[DateTime] >= "2011-12-29 01:38:21.607"
)
SELECT
  *
FROM
  sequenced_records
WHERE
  sequence_id = 1

returns -> Msg 207, Level 16, State 1, Line 11
Invalid column name ‘2011-12-29 01:38:21.607’.

Update 2

guys I need to return just a SINGLE record with the minimum datetime in a group of selected items bigger than the given datetime.

Answer 1

MIN() is an aggregate, and as the error says; you must use GROUP BY to use aggregate queries. This means that you can’t get the MIN() of a group and have the individual values from one record in the group at the same time.

There are two alternatives…
– Use GROUP BY to get the MIN() and then use that to look up the record it matches.
– Use an alternative approach, such as ROW_NUMBER()

WITH
  sequenced_records AS
(
  SELECT
    ROW_NUMBER() OVER (ORDER BY [DateTime] ASC) AS sequence_id,
    *
  FROM
    xx.dbo.StreamView
  WHERE
    StreamView.TypeOf = 3
    AND StreamView.[DateTime] >= "Some DateTime Value Here"
)
SELECT
  *
FROM
  sequenced_records
WHERE
  sequence_id = 1

NOTE You do need real datetime in there, such as ‘01012012 23:34’

For environments without ROW_NUMBER() you’d revert to the aggregate approach, using two steps. Such as…

SELECT
  *
FROM
  StreamView
WHEREE
  TypeOf = 3
  AND DateTime = (SELECT MIN(DateTime) FROM StreamView WHERE TypeOf = 3 AND DateTime >= '01012012 23:34')
