Interesting Behavior, Sql 2005 Std, Order By Date Convert To String
Feb 19, 2008
Note the code below, running on the version noted.
I just found this today, figured I'd share. Not sure if it's a known bug or a "special" feature. The only difference between the two queries is the 3rd line, everything else is the same. Notice that the sort order changes, yet no errors or warnings are given. I assume that the table aliases are ignored for the order by, unless there are duplicate column names in the results.
I abstracted this from a bug I discovered in one of my apps today, where I have sales reps assigned to their clients with start and end dates. A while back, a developer asked me to format the dates without the time portion, and when I did so, I introduced the problem. I resolved it temporarily by ordering by convert(datetime, startdate) but I found it strange that the column alias match overrides the table alias attempted match in the order by. Another way to get around this would be to change the column aliases, then the sort order would be as desired, but I didn't want to have to change the app code for something so trivial.
My apologies if this is a duplicate.

I've been experimenting with the new SQL Server Service Broker, and I think I've discovered some interesting behavior. Service Broker relies on "Queues" to store messages that need to be processed. Service Broker operates by sending a message from one Queue (the INITIATOR Quque) to another Queue (the TARGET Queue). A Queue can have an "Activation Stored Procedure" associated with it. This procedure is what actually processes the messages in the Queue.
The first behavior I obeserved related to the setting of a Queue's RETENTION parameter. The RETENTION parameter indicates whether or not the Queue will retain a copy of the messages it receives. By default, the parameter's value is "OFF" (meaning it will not retain messages). In the Activation Stored Procedure of my TARGET Queue, I used "sp_send_dbmail" to send an e-mail message. I wanted to capture the "conversation_handle" (a uniqueidentifier that identifies a particular message) and include it in the body of the e-mail. I was unable to capture it, because the Queue's RETENTION parameter was "OFF". When I tried to capture the conversation_handle from the INITIATOR queue (whose RETENTION parameter was "ON"), I was successful. The moral of the story is you apparently need to have RETENTION = "ON" if you need to capture information from a Queue.
The second behavior I observed relates to the setting of a Queue's MAX_QUEUE_READERS setting. This setting allows you to automatically invoke multiple instances of the Activation Stored Procedure. As messages come into the Queue, the Queue creates an additional instance of the Activation Stored Procedure up to the number you specified in the MAX_QUEUE_READERS setting. This allows parallel processing of messages in the Queue. There is also a programming technique called a "RECEIVE LOOP" which is used for processing messages. In the RECEIVE LOOP, you have a parameter called WAITFOR which tells the Queue whether it should stay on constant alert for new messages or whether it should time out after a specified number of seconds.
If you have the Queue wait indefinitely (by not specifying a TIMEOUT value in the WAITFOR statement) and you have invoked multiple copies of the Activation Stored Procedure, the procedure will remain in memory indefinitely. Therefore, if you make a change to the code of the Activation Stored Procedure, the change will NOT be reflected in the Activation Stored Procedure until you change the STATUS of the Queue. I had changed my procedure so that it would not send an e-mail, but the e-mails kept coming. The e-mails did not stop until I executed an ALTER QUEUE statement. I ran "ALTER QUEUE queue_name WITH STATUS = OFF;" and then I ran "ALTER QUEUE queue_name WITH STATUS = ON;" After that, the changes were reflected in the procedure.
Be aware of this behavior as you design your Queues.
Hi!I have a little problem. I’m trying to sort a date I have converted like thisConvert(datetime,LH.LoginDateTime,103) as RegistrationDateBut when I use Order by on RegistrationDate it only sort on days:01/11/200601/12/200602/11/200602/12/200603/11/200603/12/2006I’ll guess it’s because of the “varchar� convert, but I need the date to bee inn this format, since I only shall check the date and not the time. Is there a way around this, so I can order it like this? (Se under)01/11/200602/11/200603/11/200601/12/200602/12/200603/12/2006Sample SQL;select Convert(varchar,LH.LoginDateTime,103) as RegistrationDate,select count(*) from LoginHistory AS LH2 where datepart(hh,LH2.LoginDateTime)<7 ANDConvert(varchar,LH2.LoginDateTime,103)>=Convert(varchar,LH.LoginDateTime,103) AND Convert(varchar,LH2.LoginDateTime,103)<=Convert(varchar,LH.LoginDateTime,103)) As beforehour07from LoginHistory AS LHwhere LH.LoginDateTime >='''+ Convert(varchar,@FromDate,113) + ''' ' + 'and LH.LoginDateTime <='''+ Convert(varchar,@ToDate,113) + ''' ' + 'group by Convert(varchar,LH.LoginDateTime,103)'Order by RegistrationDate
I have a table in which a date value is stored as varchar.some of these values are stored ina dd/mm/yyyy format and other values are stored in a yyyy-mm-dd format..Now I wish to retrieve some data by querying between two dates. However I need to convert the varchar date value to datetime in order to do this but since the date value is in two different formats, the following doesn't work.
select date_value from my_table where CONVERT(DATETIME, date_value, 103) between @date1 and @date2
How can you convert the date value to datetime when its stored in mutiple formats. I can't change the table itself as I dont have admin privelages.
I am using DTS to read in a date with the format of YYYYMMDD. I am trying to convert this date to MM/DD/YYYY and then use the CDate function with the following code to load it into a Datetime column in SQL Server:
DTSDestination("DateName") = strHoldDate Main = DTSTransformStat_OK End Function
My DTS package will execute without errors, but it does not add the row. I have been successful using CDate when the source date is in the format MM/DD/YYYY.
Also, do you have any tips on how to debug DTS? How to see what's in a variable, etc.?
In our ERP system we have a field which is a date-picker in the user front end, but the value is stored in an NVARCHAR field and not always consistently. How can I convert this to a date (preferably in the format YYYY-MM-DD HH:MM) that I could use in a calculation?

Hello forum, Is it possible to convert a date stored as a string into a datetime with integration services 2005? My attempts with the €œdata conversion€? fail. The string type form of the date is €˜yyyy-mm-dd€™ and the desired result for use in a Union All is €˜dd/mm/yyyy 12:00:00AM.€™ This outcome is needs so that match on the date can populate a fact table, as the results are coming from two different databases. All advice/help welcomed. Ian
Hello Everyone, How can I convert the string column to date in SSIS. Example: I have a column which is having a value as €œ19890213€? Basically this values is a date Now I wanted this value to be a date value as €œ01/01/2007€?
i had try it out by doing this ways (DT_DATE)(SUBSTRING(DATE_SEEN_SPEC,5,2) + "/" + SUBSTRING(DATE_SEEN_SPEC,7,2) + "/" + SUBSTRING(DATE_SEEN_SPEC,1,4))
but still i'm getting the error message.
I know the this can be achived through type cast in Derived Column compunent, but not sure with which cast please help me out in resoulving this issue.
I am trying to create a report that sums up new cases weekly based on the previous 5 months. I have included some sample data below. The only field that displays a date is called monthSubmitted, varchar 7 and not very useful. How can I first convert this firld to a date ddmmyy?
How would you the code it so the user can run the report on demand at any given time and display the data for the last 5 months on a weekly basis? I am not sure as to how the date calculations should be coded.
Im working with a breaking system and I wont to convert the (FROM) datetime column to accept just time like (4:00:00 AM) without the date (7/23/2004) but it doesn’t have column format like the access ?? I found something in the SQL help :

I have two fields DSRHADTI which is an isodate and DSRHTIME which is 8 char time field in format 10.31.00. I want to take both these fields and put them into a field that is database timestamp so I have converted DSRHDATI to 10 character field. I am then trying to use substring to put both into 18 character field using derived column transformation editor. but it does not like the below. It's red syntax error what am I missing.
(SUBSTRING(Copy of DSRHDATI,1,4) +' /' + SUBSTRING( Copy of DSRHDATI,6,2) + '/ ' + SUBSTRING(Copy of DSRHDATI,9,2)) + SUBSTRING(DSRHTIME,1,2) + '.' + SUBSTRING(DSRHTIME,4,2) + '.' + SUBSTRING(DSRHTIME,7,2)
One I get the above to work I plan on convert 18 char to datetimestamp.
I am using Access 2003 as a front-end to a SQL Server 2005 database.I make design changes using SQL Server Management Studio. I have atable that includes a datetime column. I create a view and sort bythe datetime field. When I initially look at the result it is sortedcorrectly. Then I save the view and re-open it and it is not sorted.I've simplified the view so it only contains the date field and itstill does not sort. Here is the view:SELECT TOP (100) PERCENT Period_DateFROM dbo.Period_SummaryORDER BY Period_Date DESCThe date seems to be a random order.I don't have this problem in the SQL Server 2000 version of thedatabase.Help please!Thanks,Jerry

Dear Experts,Ok, I hate to ask such a seemingly dumb question, but I'vealready spent far too much time on this. More that Iwould care to admit.In Sql server, how do I simply change a character into a number??????In Oracle, it is:select to_number(20.55)from dualTO_NUMBER(20.55)----------------20.55And we are on with our lives.In sql server, using the Northwinds database:SELECTr.regionid,STR(r.regionid,7,2) as a_string,CONVERT(numeric, STR(r.regionid,7,2)) as a_number,cast ( STR(r.regionid) as int ) as cast_to_numberFROM REGION R1 1.00112 2.00223 3.00334 4.0044SELECTr.regionid,STR(r.regionid,7,2) as a_string,CONVERT(numeric, STR(r.regionid,7,2) ) as a_number,cast (STR(r.regionid,7,2) as numeric ) as cast_to_numberFROM REGION R1 1.00112 2.00223 3.00334 4.0044Str converts from number to string in one motion.Isn't there a simple function in Sql Server to convertfrom string to number?What is the secret?Thanks

Well this Query should return the raiserror it returns completes successfuly since todays date is not the same as the date in the database. if you select @datefin_flag it returns NULL and if you select @strip it brings back todays date how can NULL be equal to to todays date assuming that todays date is equal to NULL. ?
Hi, I just realized that when I started using the CONVERT function on my dates in my SELECT statement and try to ORDER BY one of the date fields that I convert, the order isn't actually correct. Here's the statement:
$query = "SELECT id, BroSisFirstName, BroSisLastName, TerrNumber, IsCheckedOut, IsLPCheckedOut, BroSisFirstNameLP, BroSisLastNameLP, CONVERT(char(10),CONVERT(datetime, CAST(checkedOutDate as varchar(12))),101) AS checkedOutDate, CONVERT(char(10),CONVERT(datetime, CAST(returnedDate as varchar(12))),101) AS returnedDate, CONVERT(char(10),CONVERT(datetime, CAST(lpcheckedOutDate as varchar(12))),101) AS lpcheckedOutDate, CONVERT(char(10),CONVERT(datetime, CAST(lpReturnedDate as varchar(12))),101) AS lpReturnedDate FROM Checkouts WHERE IsClosed < 1 ORDER BY checkedOutDate";
It's almost as if it's treating the date as a string. Does anybody know why, and how I can correct the issue? I need to use the CONVERT function because I don't want the whole 00:00:00 returned with each date. And I say it's the CONVERT function because if I take off the CONVERT on one of the fields such as checkedOutDate and try to sort by it, it sorts correctly.
So I have to build dynamic T-SQL because of a date parameter that will be provided. The Date Parameter will be provided in SSRS in normal MM/DD/CCYY format. So how do I then convert that date to my Oracle format
Hi there. I'm trying to extract data from my SQL server & everything in the script I've got is working (extracting correct data) except for one field - which is for the most part it's off by +2 days (on a few occasions - I see it off by just +1 day or even +3, but it's usually the +2 days).
I'm told that it's due to the conversion formula - but - since SQL is not my native language, I'm at a bit of a loss.
The DB table has the date field stored as a type: CHAR (as opposed to 'DATE') Can anyone out there help?
