Jul 20, 2005At my current workplace, whenever I check table sizes using the'reserved' column from sysindexes, or sp_spaceused, I get a total forall user tables which exceeds the physical size of the database.Running sp_spaceused with no parameteres, I get a NEGATIVE value forunallocated space in the database, but only see this if I return theresults in GRID format in QA (text format gives less output):DatabaseName DatabaseSize Unallocated Spacexxxxx_xxxxx11502.38 MB-4874.80 MBReserved Data index_size unused16602800 KB7013752 KB2381904 KB7207144 KBIf I re-run sp_spaceused with the @updateusage='TRUE' option, thisoutput gets corrected to:DatabaseName DatabaseSize Unallocated Spacexxxxx_xxxxx11502.38 MB2773.76 MBReserved Data index_size unused8770680 KB6928168 KB1808096 KB34416 KBwhich shows a substantial difference in the Reserved/Data/Index/Unusedsizes.This happens every day - any ideas about:1) Why this might be happening on such a large scale, and2) Is it conceivable that these discrepancies in space allocationinformation could be causing performance problems?

Jun 4, 2007I've sure I have a problem that hasn't been addressed on the forum exactly. I have a SQL 2000 database that the SSIS designer sees, meaning it is a member of the 'Server Explorer' group. I am trying to update my SQL 2005 database based on values from a SQL 2000 database table using an OLE DB Command data flow transformation. I use a SELECT query in the OLE DB Source control to get the required columns. I use an UPDATE statement to identify where to place the columns retrieved from the source. I get an error that tells me that the update statement fails because it can't identify the SQL 2000 database I am trying to use. The highlighted part of the error is something I haven't seen in the similar posts I've read. And, it's ironic because the server is actually 'linked'.

Clustering For Anomaly Detection
Mar 14, 2008Hi,
I have been trying to use the Clustering algorithm for Anomaly Detection, but it has been quite difficult to get correct results for PredictCaseLikelihood.
Using a very large number of clusters helped, but there are other problems.
The algorithm does not take into account all the columns in my nested table, but only uses Exists/Not Exists for the nested table key column. In my case the nested table contains also a column with a count of key attribute.
I am about to abandon the Sql Data Mining.
Does anyone have more insights into tuning the Clustering algorithm for anomaly detection?
Thanks

Dateadd Date Calculation Anomaly
Apr 3, 2008I am doing monthly reporting for whole months, all starting on the 1st of each month and finishing on the last day of the month
I use dateAdd to calculate the end of the month - so I add 1 month and subtract 1 second (start time is always 00:00:00).
--dFrom is Jan 01 2008 00:00:00
select @dTo=dateadd(ss,-1,dateadd(mm,1, @dFrom))
when I print dTo it is not Jan 31 2008 23:59:59 but Feb 01 2008.
Why is this?
Only starts to behave when I set the number of seconds I am adding from -1 to -31.
Time of date is unimportant: as storing all dates as midday (any data type which ONLY supports date? not interested in the time really).
Subtracting one minute from midnight works fine, but that said: I am curious to understand why I am getting the funny behaviour above.
1. Maintenance Cleanup. 2. 'View History' Anomaly
Mar 31, 2008Hi. I'm very new to SQL Server and would greatly appreciate any advice with regard to my two questions below.
I've recently been given responsibility for a pair of clustered Windows 2003 servers running SQL Server 2005. Looking through SQL Server Management Studio, I found the following three maintenance plans:
- System Maintenance Plan (all system databases)
- Plan 1 (1 database)
- Plan 2 (4 databases).
All three maintenace plans had the following elements configured, in the following order:
- Check Database Integrity
- Backup Database (Full)
- Shrink Database
- Update statistics
- Clean Up History
with the exception that Plan 1 doesn't have a 'Shrink Database' task (because, I'm told, its data is pretty static), but none had a Maintenance Cleanup Task, so I added one to each plan specifying 14 days of old backups to be kept in all cases except Plan 1, where I limited it to 2 days, the database being over 7 GB in size. All links between tasks in all plans are AND constraints, value 'Completion'. All .BAKs are written to tape by Symantec Backup Exec as part of the daily backup.
Two questions from this:
1. Since .BAKs are written to separate folders for each database, do I need, for example, four Maintenance Cleanup Tasks for the Plans covering four databases - one for each folder/database? I can't see a way of specifying that a Maintenance Cleanup Task should apply to multiple databases or search subfolders based on database name, so I assume I need four consecutive Maintenance Cleanup Tasks within a single plan? Is this the way to do it?
2.The data displayed when I right-click a maintenance plan and choose View History shows:
date and time run
plan name
task name
duration
log type
log source
Since I added a Maintenance Cleanup Task to each plan, the only task shown in the Task Name column is Cleanup History (set to 'Older than 7 days'), and the duration is 00:00:00, where previously all tasks were shown and the overall duration was over a minute.
However, the .BAK files are being created (size looks OK), the application log contains entries suggesting the backups and other tasks completed successfully, and if I expand the SQL Server Logs node and view the current file I can see entries which give the same 'success' messages (presumably this log is the source of the 'success' messages in the application log?).
Why does there appear to be an anomaly between the 'View History' display and the SQL Server Log and application log? Should I be worried, or is what I can see in the SQL Server Logs and application log sufficient grounds for a good night's sleep?
Thanks,
Ed
Strange Date/time Anomaly, Or Am I Just Stoopid?
Aug 30, 2005To set up the problem, paste this into QA:if exists (select * from dbo.sysobjects where id =object_id(N'[dbo].[WorkOTRate]') and OBJECTPROPERTY(id, N'IsUserTable')= 1)drop table [dbo].[WorkOTRate]GOCREATE TABLE [dbo].[WorkOTRate] ([TimeFrom] [smalldatetime] NOT NULL ,[TimeTo] [smalldatetime] NOT NULL ,[RateMultiplier] [float] NOT NULL) ON [PRIMARY]GOINSERT INTO dbo.WorkOTRate (TimeFrom, TimeTo, RateMultiplier)VALUES ('18:00:00', '23:59:59', 1.2)SELECT TimeFrom, TimeTo, RateMultiplier FROM dbo.WorkOTRateThis gives the following result:1900-01-01 18:00:001900-01-02 00:00:001.2So, it's storing the time 23:59:59 as midnight. That's odd.(NOTE: If you rescript the table using datetime instead ofsmalldatetime types, the data are stored correctly.)It gets worse (or better, if you like perversity).If I go to Enterprise Manager, right-click on WorkOTRate and select"Open Table" -> "Return All Rows" I get:01/01/1900 18:00:0002/01/19001.2So, I bite the bullet and change the two column types to datetime,clear out the old data and run the INSERT again. The data looks betternow.Go back to the view in EM.If I put the cursor in a new row, and type into the TimeFrom column18:30:00 and the TimeTo column 19:30:00 and the RateMultiplier column1.3, and refresh the data by pressing the red shriek !, I get this:01/01/1900 18:00:0001/01/1900 23:59:591.218:30:0019:30:001.3If I re-run the SELECT from the QA, I get this:1900-01-01 18:00:00.0001900-01-01 23:59:59.0001.21899-12-30 18:30:00.0001899-12-30 19:30:00.0001.3Is it just me, or does this seem to be remarkably inconsistent?Edward

Execution Time Anomaly In Stored Procedures In SQL Server 2005
Dec 3, 2006Background: We have SQL Server 2005 x64 running on a quad-core (dual dual-core) machine with 16GB of RAM. The database is about 10GB in size and we execute around a million stored procedures a day on it. Our application uses about 1000 different stored procedures on this machine. The application is a transactional B2B web-app with about 2000 users.
The problem we have is a really odd one that I can't seem to find much information on. We have a small number (3-4) of stored procedures that's exibiting this problem.
The stored proc in question takes on average 100ms CPU time to execute. It's a fairly complex stored proc, about 300 lines long, 6-7 select statements and it uses temp tables. No updates / inserts except for on the temp tables. It's executed about 5000 times per day. About once a week, though, execution times will suddenly jump up to 3000 ms average. This happens randomly during the day, although it seems to happen more often on Monday mornings (the DB is mostly unutilized over the weekend)
To fix this, I force the DB to recalculate the execution plan by adding / removing (depending what I did last time around) the line 'set arithabort on' at the top of the stored procedure. I have no idea why this works, but it does. Within seconds of changing it, the stored proc execution time will go back to it's normal range of 60-150ms.
I've tried setting the execution plan of the stored procedure but I can't get it to work - the execution plan is very long and I don't know how to debug the error I get.
What is happening? This happens with a couple of stored procedures - usually the more complex ones. Has anyone seen anything like this?
Problem With Isnull. Need To Substitute Null If A Var Is Null And Compare It To Null And Return True
Sep 20, 2006Hey. I need to substitute a value from a table if the input var is null. This is fine if the value coming from table is not null. But, it the table value is also null, it doesn't work. The problem I'm getting is in the isnull line which is in Dark green color because @inFileVersion is set to null explicitly and when the isnull function evaluates, value returned from DR.FileVersion is also null which is correct. I want the null=null to return true which is why i set ansi_nulls off. But it doesn't return anything. And the select statement should return something but in my case it returns null. If I comment the isnull statements in the where clause, everything works fine. Please tell me what am I doing wrong. Is it possible to do this without setting the ansi_nulls to off??? Thank you
set ansi_nulls off
go
declare
@inFileName VARCHAR (100),
@inFileSize INT,
@Id int,
@inlanguageid INT,
@inFileVersion VARCHAR (100),
@ExeState int
set @inFileName = 'A0006337.EXE'
set @inFileSize = 28796
set @Id= 1

set @inFileVersion =NULL
set @ExeState =0

DR.[FileName] = @inFileName
AND DR.FileSize =@inFileSize

Subscription Issue With Null Default Parameter - Key Cannot Be Null
May 3, 2007I have a report that is run on a monthly basis with a default date of null. The stored procedure determines the month-end date that it should use should it be sent a null date.
The report works fine when I tell it to create a history entry; however, when I try to add a subscription it doesn't appear to like the null parameter value. Since I have told the report to have a default value of null it doesn't allow me to enter a value on the subscription page.
Now, I suppose I could remove the parameter altogether from the stored proc, but then the users would never be able to run the report for a previous time period. Can someone explain to me why default values aren't allowed to be used on subscriptions when they seem to work fine for ad hoc and scheduled reports? This is really quite frustrating as most of my reports require a date value and default to null so that the user doesn't have to enter them for the latest data.
An internal error occurred on the report server. See the error log for more details. (rsInternalError) Get Online Help

Returned SQLParam.SqlValue Is {Null} But Can't Test For Null?
Nov 5, 2007I run a stored procedure for which I have a return variable. The stored procedure returns the ID of a row in a table if it exists:
m_sqlCmd.ExecuteScalar();
The m_sqlCmd has been fed an SQLParameter with direction set to output.
When the stored proc returns, I want to test it. Now when there IS a row it returns the ID ok.
When the row doesn't exist, in my watch I have:
m_sqlParam.SqlValue with value {Null}
I can't seem to work out how to test this value out.
I've tried several things but none seem to work.
This line compiles ok, but the following runs into the IF statement as if the SqlValue is null??
if (m_sqlParam.SqlValue != null)....
{
// I'm here!! I thought the watch says this is null???
}
Sorry if this is obvious, but I can't work this one out!!

WITH RETURNS NULL ON NULL INPUT Not Working?
May 3, 2006Hello.
I've built a sample CLR function with the following declaration....
CREATE FUNCTION GetManager(@DeptCode nvarchar(3))
RETURNS nvarchar(1000)
WITH RETURNS NULL ON NULL INPUT
AS
EXTERNAL NAME Assembly1.[ClassLibrary1.MyVBClass].MyManager
And it works as expected, except when I use NULL:
DECLARE @MyManager nvarchar(1000)
EXEC @MyManager = dbo.GetManager NULL
PRINT @MyManager
It returns the value "Unknown" as it would have for any unknown DeptCode, as-programmed.
I'm of the theory it should have returned NULL without actually firing the function? Or is this only for non-CLR items... or stored procedures, not functions?

Now there is another similar column -colz varchar(10) which stores date but doesnt have case condition so whenever date has no value its shows null which is database null.
So whats the difference between database null and string null ?
How can we show database null for the case condition instead of string "null"?
Adding Null And Non-null Columns Together ----??
Nov 27, 2000I have two columns A (which allows nulls) and B( which does not allow nulls).
How can I add the contents of columns A and B SO THAT I DO NOT GET A NULL RESULT WHEN A IS NULL.
The result of A+B concatanation will be stored in a column, C.
Appreciate your help

Null Result Returned Even Though IS NOT NULL Specified.
Apr 25, 2007Hi guys,
I've got a query on a particular table returning an odd result:
SELECT DISTINCT WorkStation
FROM Invoice
WHERE WorkStation Is Not Null
ORDER BY WorkStation
This query returns the rows I'd expect plus a null row. This doesn't happen in databases at other sites, or in other tables at this site. The following query behaves as I'd expect returning only non-null AccountNumbers.
SELECT DISTINCT AccountNumber
FROM Suppliers
WHERE AccountNumber Is Not Null
ORDER BY AccountNumber
I can't reproduce these results on another site on a table of the same structure, or on another table at this site.
Any suggestions as to what might be going on?

Does not reproduce this problem (and so is a probable fix) but the questions remains, what causes this?

Default Constraints NULL / Not NULL
Aug 2, 2015I have 595 default constraints in my database. I can return a list of them using the following:
select * from sys.default_constraints
Is there a way I can return a list of just the ones where NULL is still allowed? I want to update all of the columns with a default value to not allow NULLs.

Changing The Column From NULL To NOT NULL
Feb 28, 2008Hi all,
One of my columns is the table has some Null values, and I Would like to stop having NULL values into that column any more.
I know, If I alter the column to NOT NULL will throw me an error, since it does a batch update.
Is there any way to achieve this...
Thanks...
Value Is Null Remotely - Non Null Locally
Aug 15, 2006ok here is a WIERD issue.
I've NEVER EVER had this issue, I have always done this and it works great both locally and remotely.
I have a table, which is a "customers" table.
I have a stored procedure which takes in parameters (name, address, password etc...) and returns me back, via a parameter declared as output - the customer ID.
I've always done this, and works great.
Now, this works fine locally.
IF I try to run this/do the exact same execution of commands (create a customer) remotely (where the database is stored, so copying everything from local to "over there") it does not work.
I get a DBNULL value back from the parameter, declared as an int output.
IF I copy and paste this Stored procedure Query/command into Query Analyzer and execute it (on the remote connection) and run it, giving it the exact same values as I do, it works perfect and returns me the correct value.
I've even dropped and recreated the stored procedure but makes no difference.
Any ideas why?
here is the proc....
CREATE PROCEDURE [dbo].[DoCreateNewCustomer] (
@theFirstName nvarchar(25),
@theLastName nvarchar(25),
@theAddress nvarchar(50),
@theCity nvarchar(15),
@thePostCode nvarchar(9),
@thePhoneNumber nvarchar(21),
@theMobilePhoneNumber nvarchar(21),
@theIPAddress nvarchar(25),
@thePassword nvarchar(50),
@theEmailAddress nvarchar(30),
@result int output
)
AS
SET @result = (SELECT [ID] FROM Customers WHERE emailAddress = @theEmailAddress)
IF @result IS NOT NULL
SET @result = -1
ELSE
BEGIN
SET @result = @@IDENTITY
INSERT INTO Customers (
Firstname,
Lastname,
Address,
City,
Postcode,
PhoneNumber,
MobileNumber,
IPAddress,
[Password],
EmailAddress
)
VALUES (
@theFirstName,
@theLastName,
@theAddress,
@theCity,
@thePostCode,
@thePhoneNumber,
@theMobilePhoneNumber,
@theIPAddress,
@thePassword,
@theEmailAddress
)
END
GO
Any ideas why it does not work when calling the stored proc from either a web app, or through QA remotely but works fine when I run that command in QA or locally?
Again, if I do:
EXEC DoCreateNewCustomer { params } - the output result it gives me is DBNULL (if on remote connection)
If I do this locally, perfect
If I copy and paste pretty much the SP into QA and execute it on the remote connection, works great, and also locally.
