Cast As Numeric Mystery
Feb 8, 2008
I have a varchar field with leading alpha, plus 1 or 2 numerics, like 'A2' or 'A20'
And yet,
select cast(substring(T2.ALPHANUM_CODE, 2, 4) as numeric)
from ...
where ...
/* and substring(T2.ALPHANUM_CODE,2,1) not like '[0-9]' */
/* and substring(T2.ALPHANUM_CODE,3,1) not like '[0-9]' */
/* and substring(T2.ALPHANUM_CODE,4,1) not like '[0-9]' */
/* and substring(T2.ALPHANUM_CODE,5,1) not like '[0-9]' */
this generates a cast as numeric conversion error in my result set.
However, if I supplement my query with each of the commented WHERE clause add-ons in turn, I get 4 zero-record result sets.
So, how can I have nothing but digits 0 thru 9 in each of 4 positions, but the cast as numeric attempt of those 4 character positions as a string fails?
Any thoughts?
Thanks ...

I have a varchar(len=9) field that I want to cast as numeric(9,2). Some of the field values are null but some have valid values (ie 1.00 or .05).
I am selecting data from one table and then updating a different table.
I have a select statement within an insert statement and then an update statement. I've tried a cast statement but not successfully. I get the following error.
[Execute SQL Task] Error: Executing the query "Exec sp_ESTLoadPOData" failed with the following error: "Error converting data type varchar to numeric.". Possible failure reasons:
Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly.

set @a=99362600999900.0000
The 99362600999900 value before numeric is 14 and variable that i declared is of 16 length. Then why this error is coming ? When I set Length 18 then error removed.

Guys
I'm getting the above when trying to populate a variable. The values in question are :
@N = 21
@SumXY = -1303765191530058.2251000000
@SumXSumY = -5338556963168643.7875000000
When I run, SELECT (@N * @SumXY) - (@SumXSumY * @SumXSumY) in QA I get the result OK which is -28500190448996439680147097583285.072256 ie 32 places to left of decimal and 6 to the right
When I try the following ie to populate a variable with that value I get the error -
SELECT R2Top = (@N * @SumXY) - (@SumXSumY * @SumXSumY)@R2Top is NUMERIC (38, 10)
Any ideas ??

I have a table Catalog_Item with 365000 rows. I wish to move the contents of the table to an identical database on a different server using bcp. The table has no primary keys, foreign keys, or indexes. I am able to successfully bcp out the data in character format and native format.
I attempt to bcp the data in to the identical table on the other server, but
the bcp ALWAYS fails at 19000 or 20000 rows; it does not complete, just hangs there in the command window, with no more info. When I use a small data set of 5000 rows, the same happens at the end of those 5000. I have tried to redo the bcp in native mode, and character mode. I have tried to specify the first line starts at 125000. I have tried to bcp the data into a different database on a different server; that also quits at 19000 or 20000 rows.
BCP of other large data sets into the same database occurs smoothly. Only this combination of table and data set is giving this problem.
any ideas?

I am having trouble connecting to an SQL Server from an ASP.NET page
written in C#. I have reduced the code in my page to this: public void Page_Load( object s, EventArgs e ) {
SqlConnection conn = new SqlConnection( "Server=server;User ID=user;Password=pass;" );
conn.Open();
} and I get the following error:
System.Data.SqlClient.SqlException: SQL Server does not exist or access denied.
This
works for other server/user/pass except the one I am having trouble
with. The SQL Server is using SQL & Windows Authentication. I am
able to connect from the machine that is running the webserver via
osql, ODBC, and MS Access using the same arguments (server, user, and
pass), so I know that the SQL server does exist, and the User/Password
should give me access. Does anyone have any ideas why this
isn't working or what ASP.NET is does differently from the other access
methods? Any ideas are greatly appreciated. Thanks, Mark Dane

I have created a maintenance plan which backups to a device which I have created. However the device does not show in explorer and maintenance plan cannot find it when it trys to open the device. Consequently I'm not getting a backup.
Even if I delete the device and re create it things don't change.
Running SQL 7 SP1 on NT SP5 with SMS 2 SP1.
Any help gratefully received....

I was working at a customer site and wanted to verify that backups were indeed being run successfully before I began to make changes.
I noticed a dump device for the production database with the nightly backup in it but I cannot find the task that produces this dump. I did find the task that dumps the log each hour.
Is there another area that some of you DBAs used to schedule dumps other than the task manager that I might be missing? Maybe an AT job?
Thanks.

I am trying to track down an account in SQL 6.5 that keeps showing up in my failed login log. We are using Standard Security.
The log doesn't provide much detail other than the attempted login name and the time/date.
Any ideas on how to track down more information on this mystery account would be appreciated.

Hey All,
Hope this is the right place for this post.
I set up logshipping between two databases recently. everything looks fine. the backup, copy and restore jobs are all suceeding(from the job log). the problem is no Tlogs are being restored in secondary database. The restore job skips all the tlogs and says it did not find any tlog back up file to restore!! The jobs finishes with this:

In general, patch management solutions use an approach very similar to inventory and deployment, although, obviously, implementation details vary. Inventory relies on an external database to establish what is considered to be a recommended patch level and provides criteria for validating whether a particular patch has been installed. Products from Microsoft and Shavlik Technologies (on which HFNetChk, MBSA, and SMS 2.0 Feature Pack are based), keep track of published patches on the Microsoft Web site using the same mechanism, based on an XML formatted file called mssecure.xml. This file, available centrally at predefined locations, serves as a template against which the status of updates on target systems is compared. mssecure.xml can be obtained directly or via its compressed, digitally signed version, mssecure.cab. Both files can be downloaded from:
the Microsoft Web site at https://www.microsoft.com/technet/security/search/mssecure.xml and http://download.microsoft.com/download/xml/security/1.0/nt5/en-us/mssecure.cab
the Shavlik.com Web site at https://xml.shavlik.com/mssecure.xml and http://xml.shavlik.com/mssecure.cab

Calling any OLAP Guru's. Were attempting to improve a vendors BI process which involves running MDX queries against our SSAS cube, then saves the data into their own proprietary database which is taking to long.
We currently run this process on a x16 CPU, 65GB top end server attached to expensive disk subsystem, however a dual-core processor
laptop completely out performs the expensive hardware by around 45% quicker. Both when the configuration is identical or when we ramp up the processes on the expensive hardware it still performs miserably compared to the laptop. Perfmon counters or Profiler don't so much difference when comparing the server and laptop.
Does anyone know why the laptop completely outstrips the expensive top end hardware perfmance wise although the configuration profile is identical?

Hi all,
I found problem with my database and was wondering if anyone here could shed some light on the issue.
I have two tables, Absences and AbsenceDates. The first one records the absence of an employee and the second one records a record for each day of the occurance. I do a full select on the second table and I see primary keys that do NOT exist in the select of the second table. so I dug further and here is what I found.
Select * from Absences (rowcount in Query Analyser is: 20883)
Select * from Absences Order By AbsenceID Desc (rowcount is 443)
The second select contains the data that I am missing in the first select. So, I called a friend and they said to run DBCC CHECKDB and I did. The data came back as follows...
DBCC results for 'Absences '.
There are 21337 rows in 243 pages for object 'Absences'.
CHECKDB found 0 allocation errors and 0 consistency errors in database 'EmployeeAbsenteeism'.
DBCC execution completed. If DBCC printed error messages, contact your system administrator.
now if you add up the rows that the other two selects return it comes to 21326, not 21337. I am assuming that the value that DBCC gets is from sysobjects and that some sort of update would need to be run for it be accurate. This I don't care about too much, what I really need is for my main select statement to return ALL of the data, not just what it feels like returning.
My experience is with programming mainly (6 years in .net) and not DBA, so any help would be greatly appreciated.
Cheers,
Brent

I'm currently running Profiler sessions to track down Lock Timeoutproblems.My Profiler view contains (amongst others) the dbid column.Much of the time, this displays familiar dbids, such as 2 (tempdb) and5 (my main user db). However, it also regularly displays IDs of 0 and132.Using SELECT DB_NAME(), these translate as "master" and "NULL"respectively.Does anyone know:a) why dbid = 0 translates to "master", when the actual id of thisdatabase is 1, andb) why Profiler reports these dbids in the first place?

I have encountred situations like this before, but this onehas me stumped.I have a pretty simple SP that collects information aboutresidential properties from a large database. First step is toquery on the basis of address or location, and collect a temptable of property IDs. Second step is to populate a compositetable of property information by joining the IDs to a table ofcharacterisitics. Third step is to update some fields by findinga single value from multiple candidates in large tables -- onehas 275 million, another 325 million rows -- e.g., the price ofthe most recent sale for a property.As an SP, this takes absolutely forever, and it seems it's doingendless scans of the large tables. So to analyze it, I took thecode and ran it as a script -- turned the parameter definition atthe top into a DECLARE statement, set values for the variablesthat are the input parameters, no other changes, and go. Presto!It runs in no time flat, and the query plans reveal it's usingthe indexes just like it's supposed to. But the SP might takean hour to do the same thing.Any suggestions about what to look for? I believe both versionshave fresh query plans -- I have recompiled (and dropped andrecreated) the SP, and the plain script should have a fresh plan.Maybe it's because the parameter values are known when the scriptruns, but not when the SP is complied? I would really appreciateany pointers, and can provide more information as needed.Thanks,Jim Geissman

CREATE TABLE [dbo].[LOG]([TYPE] [smallint] NULL ,[TIME_STAMP] [datetime],[ID] [varchar] (44))ID is non-unique. I want to select all IDs where the last entry forthat ID is of type 11.Below is the query that I used. Notice that the subquery used is anested (not correlated) subquery meaning that it doesn't use resultsof outer query. This subquery should only be executed once. However,on large number of rows (3 million), this query never returns.I have also attempted to run subquery separately. That takes 1 minute.Then I put the results in temp table and joined that temp table withthe main query. That takes about 2 minutes.Unfortunately, that solution is unacceptable to us since we have tosupport both MSSQL and Oracle with the same queries, and the syntaxfor temp tables or table variables is different in Oracle.Mysterious.Here's the query:-- main queryselect IDfrom logwhere ID in(-- subqueryselect id from log l1where time_stamp =(select max(time_stamp)from log l2where l2.id = l1.idand l2.type = 11))

I was hoping someone could shed some light on wierd situation i'm experiencing. I have the following query:
select count(*) LeadCount
from auto_leads al
where received > dbo.GetDay(GetDate())
dbo.GetDay simply returns a smalldatetime value of today's date.
Now I recently got thrown into a data mess and for some reason this query takes 8 seconds to run. Now the first thing I did was update the stats on the Received column of this auto_leads table. I re-run the query and I'm still getting 8 seconds. I look at the execution plan I can make figure out why this is happening.
I then change the above query so the filter received > dbo.GetDay(GetDate()) is now just received > '5/31/2006' and the query comes back immediately. This doesn't make sense to me because the GetDay function is really simple and comes back immediately. I then try the following query to confirm it isn't a problem with the GetDay function:
declare @Today DateTime
set @Today = dbo.getday(GetDate())
select count(*) leads
from auto_leads al
join type_lead_status tls on (tls.type_lead_status_id = al.type_lead_status_id)
where received > @Today
Sure enough, the query came back immediately. Next thing to go through my mind is that the query execution plan has been cached by SQL Server using the execution plan from before I updated the stats on the received column. So I executed sp_recompile 'auto_leads' and tryed the original query again. Still taking 8-10 seconds to come back.
So my question, is why when I remove the GetDay function call in my query filter is the query slow, as opposed to me just passing a variable into the query? Thanks!

I am trying to format a background color based on the field's value. But the expression always returns the false result.
Here is the expression I am using
=iif(Me.Value="RSB","Red","Blue")
I have also tried
=iif(ReportItems("Type").Value="RSB","Red","Blue")
Both fill the background color blue when the textbox clearly contains RSB. I'm not sure why it cannot find the value. The field data type is Char(4). The textbox values are all uppercase.
This all started when I was trying to use a report parameter for conditional formatting and I realized that it wasn't working. I broke down the expression by directly trying a value.
Any thoughts?

Hi,
I was trying to find numeric characters in a field of nvarchar. I looked this up in HELP.
Wildcard
Meaning
%
Any string of zero or more characters.
_
Any single character.
[ ]
Any single character within the specified range (for example, [a-f]) or set (for example, [abcdef]).
Any single character not within the specified range (for example, [^a - f]) or set (for example, [^abcdef]).
Nowhere in the examples below it in Help was it explicitly detailed that a user could do this.
In MS Access the # can be substituted for any numeric character such that I could do a WHERE clause:
WHERE
Gift_Date NOT LIKE "####*"
After looking at the above for the [ ] wildcard, it became clear that I could subsitute [0-9] for #:
WHERE
Gift_Date NOT LIKE '[0-9][0-9][0-9][0-9]%'
using single quotes and the % wildcard instead of Access' double quotes and * wildcard.
Just putting this out there for anybody else that is new to SQL, like me.
Regards,
Patrick Briggs,

Has anyone seen this before?
Every Sunday morning (a different time each week) there is a full backup created for every database on the server. The backup is not a scheduled backup from any maintenance plan or SQL Agent job. The backup set is unrestorable and has a strange name in the format of 'DBNAME_00_12c95fb7_399d_41ce_9a0d_b5728b6a00ba_'
Because this backup is listed as the last full backup and will not restore, it is causing a problem with our disaster recovery plans as nothing will restore from this point forward to the next full backup.
Does anyone know how a backup record like this can get created, and/or how to find the source. The backups are listed in the backupsets table in msdb - are there other system tables that may hold some clues as to the source of these backups?
Any help or direction would be appreciated.
Thanks

Guys,
In simple terms, our system is as such: We have a website. As someone clicks a button on the website, a stored procedure is executed against our database.
Every single day, between 12:15AM and 12:45AM we have a few stored procedures timing out, with the following message, for example:
2007-04-10 00:37:03,268 [3632] ERROR Service - caught exception Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding. at System.Data.SqlClient.SqlConnection.OnError(SqlExc eption exception, Boolean breakConnection)
I checked and saw that although there are jobs running at that time, all of these jobs are running periodically (e.g. every 30 minutes) and would cause timeouts at other times as well, if they were to blame. Other jobs are running at far away times and checking their history I know that their duraion in no way intersects the time-out times.
I also ran profiler during peak hours and know that no stored procedure of ours has a duration anywhere near 30 seconds (which is the currently set timeout period, although all of our sps run within milliseconds).
I am really puzzled as to what exactly is causing these timeouts. Would anyone suggest any approach to identify the problem. For example, I thought about running profiler (server side tracing) between 12AM and 1AM, but am not sure which counters are best to capture. Any suggestion on this?
Thanks a lot!

I'm importing several hundred thousand lines of text data with multiple columns in each record. While SSIS can redirect a line with an error to an error output is there any way it can "tell me" which column or columns caused the error on that row? (After al,l it certainly recognized that a column was bad, so I'm hoping it can just tell me what it found.)
TIA,

Please, help. Let me start by saying that I have asked several DBA's this question, none of which have been able to provide a solution. I have a very annoying problem. An additional backup of my SQL Server 7 database is recurring every day and it is hogging up space on the server. I only want one recurring backup.
When checking my database backup plan, it seems there is only one backup instance: qarun_1099_release1_db_200207170200.BAK and qarun_1099_release1_tlog_200207170600.TRN. However, when I look in the default backup directory, SQL/Database/Backup, there is an instance in addition to the backup mentioned above with another name: qarun_1099_release1. This "mystery" backup is neither a .BAK or .TRN, but simply a file? I cannot figure out how and where this extra backup is recurring and I want to delete it.
I have tried disabling the jobs in the sysjobsteps and sysjobs tables of the msdb database, but this did not work! The backups are still recurring every day!
Please advise.
Sincerely,
Brett

So I've been monitoring long-running transactions on a SQL Server that hosts a couple of vendor-supplied databases that look after our factory.Today I noticed a pair that have confused my Excel spreadsheet (that I've been using to analyze these transactions).So here's the weird thing that I spotted. Given this query:
SELECT p.spid, p.login_time, at.transaction_begin_time, datediff(second, p.login_time, at.transaction_begin_time) as [difference]
FROM sys.sysprocesses AS p INNER JOIN
sys.dm_tran_session_transactions AS st ON st.session_id = p.spid INNER JOIN
sys.dm_tran_active_transactions AS at ON st.transaction_id = at.transaction_id
[code]....
I had a look in the event log on the server, which had just been rebooted at around that time. It seems that the clock got changed on boot-up, with the size of it quite surprising. This meant that these processes were able to start their transactions *before* they logged on. Hopefully this doesn't cause any other weird problems.So I've requested an investigation about time synchronization on our virtualization hosts... and in the mean time, have set the SQL Server services to 'delayed start'.

I'm having a problem that I think is due to corrupt data. Depending on
the column I use in my order by clause two problems are occuring.
1. No results are returned and I get this error:
A floating point exception occured in the user process.
2. Results are returned but there are a different number of rows depending on which columns I use in my Order By clause.
Examples
SELECT * FROM SymbolStats
ORDER BY calc_date, symbol
Returns - 12207 rows but only includes one of the 25 dates in the table.
----------
SELECT * from SymbolStats
ORDER BY current_hv
Returns - 0 rows.
----------
SELECT * from SymbolStats
ORDER BY average_hv
Returns - floating point error
With more conditions in the WHERE clause the number of results returned varies greatly.
The
fact that different numbers of rows can be returned from the same query
only differing in how they are ordered seems like a bug.
Does this sound like corrupt data? If so, what are the best methods for fixing it?
Thanks,
patrick

I have function that returns a table of information about properties. Thedata comes from three different tables -- addresses (called PropertyID),property characteristics, and events concerning those properties (sales,appraisals, etc.), plus a table that maps one representation of propertytypes into another. The records are selected on the basis of location(longitude & latitude), property type, event type, and a range ofevent dates (upper and lower date specified). There are tens of millionsof records of all types, and almost any location, property type, event typeand date range will yield records.The heart of it is a cursor that selects records from joins on this basis:SELECT <a bunch of fields>FROM Property dJOIN PropTypeMap ptm ON ptm.PropertyTypeID = d.PropertyTypeIDJOIN PropertyID a ON a.PropID = d.PropIDJOIN Event e1 ON e1.PropID = d.PropIDLEFT OUTER JOIN Event e2 ON e2.PropID = d.PropIDWHEREd.LastSaleDate >= @LoDateAND a.GeoLongitude BETWEEN @LowerLon AND @UpperLonAND a.GeoLatitude BETWEEN @LowerLat AND @UpperLatAND ptm.PropCategory = @PropTypeAND a.GeoMatch <= @MinGeoQualityAND e1.EventTypeID = @SaleEventTypeAND e1.TransactionType = 'R'AND e1.EventDt BETWEEN @LoDate AND @HiDateAND e1.EventAmt > 0AND e2.EventTypeID = @AssessmentEventTypeAND e2.EventDt <= @HiDateAND e2.EventAmt > 0Each property has one PropertyID record, one Property record, and N Eventrecords (average perhaps five).What is the mystery? If @HiDate, which is the upper end of the time window,is 2002-11-08 or earlier, nothing is returned. If it's 2002-11-09 or later,oodles of records are found. I get the same query plan for either one, andbased on the content of the data, they should return almost exactly the sameset of records -- exactly the same set in almost all cases, in fact.Is 2002-11-08/09 some sort of magic dividing point? I have replicated thison the large database and on a smaller test version on another SQL Server.(SQL Server 2000) I dropped the indexes and tried it, andthe same thing happened. This is driving me crazy!

Hi
Can anyone tell me how I can CAST these fields AS DECIMAL (19, 2) please?
(SELECT ([Total students] - [withdrawn] - [transferred] - [cancelled]) / [total Students] * 100 AS [Percentage Retained])
Thanks
Daniel

I have
CASE
WHEN (a.type_id in (9))
THEN a.duration
ELSE 0 --CAST ( expression AS data_type )
END 'Time'
I need the duration to be displayed if type is 9 only.
so otherwise id ideally want 'N/A' displayed..
but it won't display it as its not an int ..
is there a way i can just display it temporarily
instaed of 0 ?
