I have 2 tables, each with one ID field, a separate
Date and Time fields and a number of other fields.
The tables contain duplicates on the ID field.
I want to do a UNION keeping only the record with the latest
Date and Time.
This would work:
SELECT MyTab.myKeyField, Max(MyTab.myDate) AS myDate
FROM (SELECT myKeyField, myDate
from Table1
union
SELECT myKeyField, myDate
from Table2) AS MyTab
GROUP BY MyTab.myKeyField
But is only taking care of Date, not Time (some records have
the same date but different times)
The other problem is, when I add more fields, I have to
include them in the GROUP BY clause, and this way I end up
with duplicates (because some other fields have different
values)
My group is working on a project for school and neither of us have much experience with SQL or ASP. We are pretty much just writing an SQL query to get the data in a certain date range and using ASP to write the tables with the data in it.
Our problem is the SQL database has separate fields for date and time. There is nothing we can do about this because the VB.NET program that populates the tables automatically does this. We can't figure out how to do the BETWEEN statement when they are separate fields. We can do it for a date range and it works fine. An example of what we want to do is show the data from 11:00 am on 04/01/2008 until 4:00pm 04/03/2008.
Does anyone have any idea what we can do? I really want to learn this but it's frustrating because we can't seem to get much help at school.
Hi,We have a lame app that uses 2 datetime(8) fields, 1 stores the date, theother the time.example query:select aud_dt, aud_tmfrom ordersresults:aud_dt aud_tm2006-06-08 00:00:00.000 1900-01-01 12:32:26.287I'm trying to create a query that give me records from the current date inthe past hour.Here's a script that gives me todays date but I cannot figure out the time:select aud_dt, aud_tm, datediff(d,aud_dt,getdate()), datediff(mi, aud_tm,getdate())from orderswhere (datediff(d,aud_dt,getdate()) = 0)results:aud_dt aud_tmdatediff(0=today) timediff (since 1900-01-01)2006-06-08 00:00:00.000 1900-01-01 12:32:26.287 055978689I added this next part to the above query but it does not work since thedate/time is from 1900-01-01and (datediff(mi, aud_tm, getdate()) <= 60)Thanks for any help.
Good morning.I am importing an XLS file into one of my tables.

We had a divestiture within our company. Now what used to be contained in one database in now split into two databases. One showing all history and one being all current data as of 6/1/2008. Is there an easy way to Union or Join these? Right now I'm currently doing a simple UNION ALL, but can't group the two select statements:
SELECT Year,Location,QtySold FROM historydb
UNION ALL
SELECT Year,Location,QtySold FROM currentdb
Can't do a subset and group both of these selects. How would some of you pro's do this? Right now I can put this in a simple view and then create a SP off of this view that would do this grouping, but it seems like I should be able to do it all in one query. Thanks.
I was working with Microsoft Time Series model (MTS) with some data, when in the mining model viewer, decision tree tab, I realized that the key time variable that I define, it was acting like a split variable.
So, I ask you, this is possible?, because, for me, this should not happen.
After, I review the Data Mining Tutorial by Seth Paul, Jamie MacLennan, Zhaohui Tang and Scott Oveson, and I found, in the Forecasting part, that the key time variable (Time Index) it was acting like a split variable too, in for example, M200 pacific:Quantity and R250 Europe:Quantity.
So people, its possible that a key time variable act like a split variable in a MTS model?
The formula for the above calculated fields are as below:
Opening Balance = carried forward balance from Year 2005 Debit = All positive amount Credit = All negative amount Net Change = Total Credit - Total Debit in Period 01 Balance = Total of Net Change + Opening Bal
Guys, hope someone out there can help me with the sql command for the above report?

I'm trying to extract some data from a table in oracle. The oracle table stores date and time seperately in 2 different columns. I need to merge these two columns and import to sql server database.
I'm struggling with this for a quite a while and I'm not able to get it working.
I tried the oracle query something like this,
SELECT (TO_CHAR(ASOFDATE,'YYYYMMDD')||' '||TO_CHAR(ASOFTIME,'HH24:MM : SS')||':000') AS ASOFDATE
FROM TBLA
this gives me an output of 20070511 23:06:30:000
the space in MM : SS is intentional here, since without that space it appread as smiley
I'm trying to map this to datetime field in sql server 2005. It keeps failing with this error
The value could not be converted because of a potential loss of data
I'm struck with error for hours now. Any pointers would be helpful.
Now I need to display the second field which is a #-separated field as individual fields alongwith tghe other fields that are shown on execution of the query. Can this be done? Please guide me on this...

I have a table that I am using in a package to create an extract from. In that table is an address field called "Street" that is 255 characters in length. My table also has 3 additional fields called address_1, address_2 and address_3 that are each 50 characters in length because that is the requirement for my extract. I need to split the address field up in such a way that if it is longer than 50 characters, it backs up to the first space in the address prior to character #50, puts that info in street1, then from that cut off point used in street1, puts the next 50 up to the prior blank space in street2, then the remainder in street3. Where the extract will be used only has three 50 character fields so if the data runs more than 150 characters, the street3 data will just have to be truncated. No way around that, but I don't anticipate any address getting close to that long. Although doing such a split would be much easier using SQL, the solution requirement is that it be done in the package, not using SQL to do so.
I'm assuming I need to use a "derived column transformation" in my data flow. But, I can't figure out how to do what I need to do with a derived column transformation.
Example of info in an address: 123 Chicamauga Avenue South, Across the Street from International Center Square, Apartment Number 17650 Tokiwa-machi Machida
position 1-50: 123 Chicamauga Avenue South, Across the Street fro
Therefore, Street1 would need to get: 123 Chicamauga Avenue South, Across the Street
I'm looking for a way of taking a query which returns a set of date time fields (probable maximum of 20 rows) and looping through each value to see if it exists in a separate table.
E.g.
Query 1
Select ID, Person, ProposedEvent, DayField, TimeField from MyOptions where person = 'me'
Table
Select Person, ExistingEvent, DayField, TimeField from MyTimetable where person ='me'
Loop through Query 1 and if it finds ANY matching Dayfield AND Timefield in Query/Table 2, return the ProposedEvent (just as a message, the loop could stop there), if no match a message saying all is fine can proceed to process form blah blah.
I'm essentially wanting somebody to select a bunch of events in a form, query 1 then finds all the days and times those events happen and check that none of them exist in the MyTimetable table.
I am trying to implement a sliding window on a table in SQL Server 2005 but i am having some problem. I have two tables, "Letture" and "LettureStorico". The first one receives data on a few seconds basis, some thousands of rows each day. The second is the historical record and should store all the records till midnigh of two days before, that is, if today is November 21st, LettureStorico stores rows till November 19th 23.59:59.997.
At some time during morning of each day i want to run a stored procedures that takes the records older than midnight of two days before in "Letture" and switch them as a partition in "LettureStorico"
Here's what i do:
/*----------------------------------------------------------*/ CREATE PARTITION FUNCTION [partizioneLive](datetime) AS RANGE LEFT FOR VALUES (N'2006-11-15 00:00:00')
CREATE PARTITION FUNCTION [partizioneStorico](datetime) AS RANGE LEFT FOR VALUES (N'2006-11-15 00:00:00')
CREATE PARTITION SCHEME [schemapartizioneLive] AS PARTITION [partizioneLive] ALL TO ([PRIMARY]) ALTER PARTITION SCHEME [schemapartizioneLive] NEXT USED [PRIMARY];/*(1)*/
CREATE PARTITION SCHEME [schemapartizioneStorico] AS PARTITION [partizioneStorico] ALL TO ([PRIMARY]) ALTER PARTITION SCHEME [schemapartizioneStorico] NEXT USED [PRIMARY]; /*(1)*/
CREATE TABLE [dbo].[Letture]( [IdLettura] [bigint] IDENTITY(1,1) NOT NULL, [IdTag] [int] NOT NULL, [IdGatewayBox] [int] NOT NULL, [IsEntrata] [bit] NOT NULL, [Data] [datetime] NOT NULL, [IsRettifica] [bit] NOT NULL, CONSTRAINT [PK_Letture] PRIMARY KEY CLUSTERED ( [Data], [IdLettura] ASC )WITH (IGNORE_DUP_KEY = OFF) ON schemaPartizioneLive(data) ) ON schemaPartizioneLive(data)
ALTER TABLE [dbo].[Letture] WITH CHECK ADD CONSTRAINT [CK_Letture] CHECK (([Data]>='20061115 00:00'))
CREATE TABLE [dbo].[LettureStorico]( [IdLettura] [bigint] IDENTITY(1,1) NOT NULL, [IdTag] [int] NOT NULL, [IdGatewayBox] [int] NOT NULL, [IsEntrata] [bit] NOT NULL, [Data] [datetime] NOT NULL, [IsRettifica] [bit] NOT NULL, CONSTRAINT [PK_LettureStorico] PRIMARY KEY CLUSTERED ( [Data], [IdLettura] ASC )WITH (IGNORE_DUP_KEY = OFF) ON schemaPartizioneStorico(data) ) ON schemaPartizioneStorico(data)
ALTER TABLE [dbo].[LettureStorico] WITH CHECK ADD CONSTRAINT [CK_LettureStorico] CHECK (([Data]<'20061115 00:00'))
Every morning i run a stored procedure that, after dropping the check constraints (i'll recreate the at the end), does the following:
/*-----------------------------------------------------------*/ SET @NewBoundary = dateadd(dd,-1, @dateOfToday)
--this new partition contains the rows i want to switch ALTER PARTITION FUNCTION PartizioneLive() SPLIT RANGE (@NewBoundary) --this new partition is empty ALTER PARTITION FUNCTION PartizioneStorico() SPLIT RANGE (@NewBoundary)
--this works fine, rows are moved ALTER TABLE Letture SWITCH PARTITION 2 TO LettureStorico PARTITION 2
--these two merges lead to two tables partitioned in two partitions each ALTER PARTITION FUNCTION PartizioneLive() MERGE RANGE (@OldBoundaryLive) ALTER PARTITION FUNCTION PartizioneStorico() MERGE RANGE (@OldBoundaryStorico)
Till now, everything is working as expected. Now, when i try to run the same Stored Procedure " a day later" (NewBoundary moved on 1 day) i receive, when i do the "ALTER PARTITION FUNCTION PartizioneLive() SPLIT RANGE (@NewBoundary)" i receive a 7707 error message: "Msg 7707, Level 16, State 1, Line 1 The associated partition function 'PartizioneLive' generates more partitions than there are file groups mentioned in the scheme 'schemapartizioneLive'."
How is this possible if i used the "ALL TO [PRIMARY]" and specified which file to use next as in (1) ? Why all this succeeds the first time (when i have 3 partitions) but not the second (again i have just three partitions, i checked) ?

What I am trying to do is figure out how much time is used for production per day. The problem is, there are production runs that run over midnight and possible multiple days without ending. For example, if I have the following data:
Hi all,I'm working on the schema for a database that must represent data about stock& bond funds over time. My connundrum is that, for any of several dimensionfields, including the fund name itself, the dimension may be represented indifferent ways over time, and may split or combine from one period to thenext.When querying from the database for an arbitrary time period, I need the datato be rolled up to the smallest extent possible so that apples can be comparedto apples. For instance, if the North America region becomes 2 regions, USAand Canada, and I query a time period that spans the period in which thissplit occurred, I should roll up USA and Canada and for records in the periodthat has both, and I should call the result something like "(NorthAmerica)(USA/Canada)" in the output. The client specifies that the dimensionoutput must represent all dimensions that went into the input.Of course, I have to account for more complex possibilities as well, e.g.Fund-A splits into Fund-B and Fund-C, then Fund-C merges into Fund-D producing(Fund-A/Fund-D)(Fund-B/Fund-C/Fund-D)(Fund-B/Fund-D)I can think of several ways to handle this issue, and they're allextraordinarily complex and ugly. Any suggestions?Thanks,- Steve Jorgensen
I have a DT_DATE column. I'd like to achieve a conditional split to ignore all records for which the date is below a specific hardcoded date (eg: 2007-03-01).
I'm having a hard time trying to express this using the conditional split transform.
What is the correct syntax to express a DT_DATE literal ?
I am trying to load previous days data at 3 am via a SSIS job.
The Date variable is initiated as DATEADD("dd",-1, GETDATE()) in the for loop.
Now, as this job runs at 3 am, and I set the variable as GETDATE() - 1, it excluded the data from 12 am to 3 am in the resultset as Date is set as YYYY-MM-DD 03:00:00:000 I need this to be set as YYYY-MM-DD 00:00:00:000
I have a Microsoft Access 2007 Database I've developed here that was designed for 2 users. Our CEO saw the Access Database and has added about 20 users. Since the additional users have been given access the Backend Access Database is being killed. I've moved the Data to SQL Server 2005 but there are 2 fields timestart and timeend that worked fine in Access but after moving them to SQL Server now show a datetime of 12/30/1899 7:00 AM instead of just 7:00 AM. So If I run a query to show the time schedule for 03/21/2008 I get nothing. How can I write the query so that it only looks at the time portion of those fields?
What I am trying to accomplish is to make a few extra columns with specified date ranges.
I have FY14 date range in the parameters at the top .. I would like to add a FY 15 column so the year would move up by 1.and also I need to add 2 more columns Prior year current month and This year, current month.
<code> DECLARE @Fy14_start datetime DECLARE @Fy14_end datetime SET @Fy14_start = '2013-07-01' SET @Fy14_end = '2014-06-30' SELECT x.ACCOUNT_NAME, X.STATUS_CODE, COUNT(X.PATIENT_CODE) AS FY14
Right the answer is probably simple but the Internet and books and everything has been no joy to me whatsoever.
I want to split my data stream based on the date. So I want to use a conditional split object to do this.
I entered the following as my case date_created > (DT_DBTIMESTAMP)"01/10/2000"
When I move off the line it stays black so appears to be okay, yet when I run my package it says it is not a boolean result and fails. Can anyone please tell me what I am doing wrong.
Also I cannot filter in the source call due to the sheer amount of work being done on the data before the split.
