When running the DBCC newalloc command I get some errors like the following:
"extent 51400 is in the wrong segment"
"chain processed with bad segment for object 448004627"
I've checked the system tables and system stored procedures and see no reference to page numbers being mapped to segments or identifying which extents are associated to which tables. I'm trying to determine which pages are associated with these extents so that I can print them to view the content. Any ideas how to determine the page numbers associated with extents and which extents are associated with each table?
Is there a way to convert an image pointer to a page ID that could beused in DBCC pagei.e.select TEXTPTR(document)FROM testdocs where id = 1resturns0xFEFF3601000000000800000003000000select convert(int,TEXTPTR(document)) FROM testdocs where id =1returns50331648dbcc page (9,3,8,1)dumps the first page of the imageI am trying to map 0xFEFF3601000000000800000003000000 - > pagenumber 8thanks
i'm not sure that i understand how sql server stores data.
in documentation, i found that sql server stores data in pages.
every page have size of 8192 bytes (8060).
as i understand well, every table row is stored in one page. also, every table row can not be larger then one page. and that's where my confusion starts - because it sounds like we can not have data in table that is larger then 8060.
please, if you can you help me to understand this.
I have a report with a column which contains either a string such as "N/A" or a number such as 12. A user exports the report to Excel. In Excel the numbers are formatted as text.
I already tried to set the value as CDbl which returns error for the cells containing a string.
The requirement is to export the column to Excel with the numbers formatted as numbers and the strings such as "N/A' in the same column as string.
I have started to look at the way our production DB has been defined and set up, with the view to improving performance.
The DB is now 11gb, and the original size was set up as 3000mb, the rest has been take in 10% additional extents.
Now, back in my DB2 DBA days, this was a bad thing to have any data spread across extents as they may not be contiguous. I am assuming that is the same with SQL Server. Can someone confirm/deny this?
If this is the case, how can I get the DB back into one primary partition?
I am reading the official documentation on pages and extents. I've also read an article on the official SQL Server Blog (sadly, I can't link as a new member). These articles do a good job explaining what an extent is.Why use extents at all?I can't find a good example anywhere of how grouping pages into extents make SQL Server work more efficiently. Any good example of what SQL Server would be missing if it didn't have extents at all, and how extents fix this?
Dynamic Log File Growths Remaining alarm becomes active when a non fixed size log file in any database is in danger of running out of space to grow. It is raised when a log file is almost full and the file cannot automatically grow enough to relieve the problem.
We have our databases with Enable Autogrowth (in Megabytes), and then a Maximum File Size (Limited to a MB value).
Example: If one of the database logs (or possibly filegroup primary) picks up another extent and is about 5 extents (arbitrary value) away from running out of growth room, an alert would be sent to an email address/profile.
P.S. Yes, there are multiple databases on this one instance and the script should loop to run through all of them.
is there a setting that will ebnable uniform extent allocation uponcreation of index/table by default ?if there isn't any default setting can you code it in?thanks,Doron
Why does M$ Query Analyzer display all numbers as positive, no matterwhether they are truly positive or negative ?I am having to cast each column to varchar to find out if there areany negative numbers being hidden from me :(I tried checking Tools/Options/Connections/Use Regional Settings bothon and off, stopping and restarting M$ Query Analyer in betwixt, butno improvement.Am I missing some other option somewhere ?
I have a table with a column ID of ContentID. The ID in that column is all NULLs. I need a way to change those nulls to a number. It does not matter what type of number it is as long as they are different. Can someone point me somewhere with a piece of T-SQL that I could use to do that. There are over 24000 rows so cursor change will not be very efficient.
I have created one reports but all the records are displaying on one page.find a solution to display the records page by page. I created the same report without group so the records are displaying in page by page.
I have an 'ID' column. I'm up to about ID number 40000, but not all are in use, so ID 4354 might not be in any row. I want a list of all numbers which aren't in use. I want to write something like this:
select [numbers from 0 to 40000] where <number> not in (select distinct id from mytable)
Hello I have a project that uses a large number of MS Data access pages created in Access 2003 and runs on MS SQL2005.
When I am on lets say my client, (first page in a series) data access page and I have completed the fields in the (DAP), I am directing my users to the next step of the registration process by means of a hyperlink to another Data access page in the same web but in a linked or sometimes different table.
I need to pass data entered /created on the first page to the next page and populate the next page with some data from the first page / table. (like staying on the client name and ID when i go to the next page)
I also need the first data access page to open and display a blank or new record. Not an existing record. I will also be looking to creata a drop down box as a record selector.
Any pointers in the right direction would be appreciated. I am some what new to data access pages so a walk through would be nice but anything you got is welcome. Thanks Peter€¦
I have recently started working on a OLAP application. The database is around 35 gig, with over half of that space being taken by the indexes. What has happened is previous developers have added indexes to attempt to improve the performance of a select statement (for reporting). Some of the indexes work, but many do not.
I would like to drop the ineffective indices. What I would like is a way to find if indexes are being used, preferably by object name. Is there a third party vendor that can monitor objects and how much they are used? Is there another way to do this using SQL?
How can get an object's dependencies in SQL Server. For example it I have written a procedure which accesses some tables inside it then the procedure is said to be dependent on that table. Or one procedure might call another procedure and hence dependent.
Can I know an object's dependent objects from any system table. I think Oracle has a table USER_DEPENDENCIES which provides this info (I may be wrong :-().
Some columns in transaction tables are "mandatory fields" on the dataentry screens, and as a result tend to accumulate junk entries, wherethe user puts something, anything, in the window in order to get theGUI to accept the screen. This filler isn't as elaborate as LoremIpsum, but more likely characters from adjacent keys on the second rowof the keyboard, like "lkjkljl". This non-data gets in the way ofapplications that use the data. I wonder if there is a way torecognize and ignore this stuff -- I would assume it's a well-knownproblem, but I haven't found any literature on it. Any pointerswelcome. And sorry if this is off-topic for a DB group.Thanks,Jim Geissman
Hi AllThe problem:!!I want to create a temp table which is common between different usersso that each user could select his rows and print them withoutprinting others selection.All clients use the same connection string.Is there a way to identify users?I think it's possible to delete rows of a user when he logs out theprogram.Do I think right?thanks very muchHafez
Has previous work been done on this? Is their a library one can download? Here's the problem. In an aricle a person or author may make a statement about a subject or a person. I am making a database on this.
For example, here in Israel, PM Olmert may make a statement on the teacher's strike or on Abu Mazen. The article may say, speaking of Mazen, Olmert said such and such. PM Olmert said, "xxxxxxx......." with the previous material making it clear whathe was speaking of.
Right now I have ugly code. Is there a neat way of doing this?
If this is the wrong forum, can somebody direct me to the right forum?
But, at the same time, also want to include two additional columns identifying or even inserting 1's against each of the first Customer_ID considering the first two columns, and the second one on the single column itself?In other words consider the following sample, how to add 1 to the last two columns where either the Customer appears for the first time in context with the Region and Branch Fields or to be appearing on it's own for the first time:
Region Branch Customer Transaction Required_A Required_B
Hell Sir, I am using repeater control to show the result after search .and using checkbox control in itemtemplate row .After searchresult i am facing a problem in identifying the checked checkboxes in the itemtemplate of repeater control . Please provide appropriate solution .... thanks for ur attention...
Hi everybody, I'm migrating a table that has above 20,000 records and lot of duplication.Let's say an Employee table with multiple records having slight diference in the EmployeeName field.Now nobody would like to sit and manually identify them with such hugh number of records. Is there any way which would help me identify most of them and reduce the redundancy.
We would have come across locks on rows, tables etc. How do we handle it through code (SP)!!!
A job is executed at 12 pm midnight on a table. This table exists on an 24X7 accessed (users will be access the table anytime in the day/night) database. We need to execute this job if this table is not locked at 12 pm. Can we have the solution for the listed are two scenarios:
1. You have a normal user and do not have system privilege. How would you design the database(Table)? Is it possible? 2. You have all the privileges on the system tables. What would be the sql script to help us identify the lock? How will it be used in your code? Or is there exception handling !!!
I wand to higllight the duplicate student .I am considering two parameter Name and Birthdate to identify such records even though the probablity of two different student having same name and same DOB is very less.Margin for bad result is relatively low for me.
Can we identify the reason for a Deadlock , after it has passed. I mean can I get to knw the reason as to why the deadlock occured yesterday on my production box.
I had not left the profiler on ... neither did I send the dead lock erorrs to the SQL error logs using the DBCC TRACEON (1204, 3605, -1)
I am trying to test some data handling between two different versions of an application.
I have restored the database schema twice, once as DB_old and once as DB_new.
I import a transaction using the new application into DB_new and I import the SAME transaction into the DB_old using the old version of application.
I then have to eyeball the data in SQL Query Analyzer to try to identify problems where the fields have received different values.
I have done this by running a select statement twice telling it to use both of the databases and then viewing it in two grids. There are a lot of columns so I have to do a lot of scrolling across the screen to do the comparison, and since the view is in two separate grids I have to hop back and forth and click the scroll bars, etc.
It seems like there has to be a better way. I don't suppose there is a way to lock the two grids so they both scroll together is there?
I was thinking maybe I could insert each of the selects into a temporary table and then do some kind of comparison to identify which values were different in each column. Some of the columns will have differences, like the timestamp, but if I could somehow identify which columns were different then I could eyeball them to identify which of those were okay to be different and which of them were actually bugs from the changed application version.
I have no idea how to identify those individual columns with different data values or even where to start.
Just so you understand better what I am doing now here is the query I am running that I then eyeball: use DB_new select * from claim where claim_id = 35144 use DB_old select * from claim where claim_id = 35144
I'm getting the following from DBCC CBECKDB (there are other errors in there, too but this is the one that concerns me at the moment):
Msg 8939, Level 16, State 42, Line 1 Table error: Object ID 1227270540, index ID 255, page (1:5359776). Test (m_slotCnt <= 1 && m_type == TEXT_TREE_PAGE) failed. Values are 8 and 1.

CHECKDB found 0 allocation errors and 4 consistency errors in table '(Object ID 1227270540)' (object ID 1227270540).
...returns null. I've checked the sysobjects table for this ID, and it doesn't show up. Any ideas on how I can identify what this object is? Let me know if you want more info. This is SQL 2000, sp4, the DB is about 60GB and it's the only one on the system having issues. The issue has been around for a while (more than a month), and is consistent. I can post all of the DBCC output if you really want/need it. I was just hesitant to do so since it's so huge.
Boy, 4th day on the job and the hits just keep coming. :-) (Not complaining. I'm learning a lot!)
UPDATE: 2007.06.04_15:44 - Funny: When I ran dbcc checktable(CheckItem), I got all of the error messages displayed below, both for the mystery object ID and for the CheckItem table. I guess that's solved, but I'd still like to know if it's possible to have identified this another way, if anyone has time. Thanks.
-D.
