Reading Results From Sys.dm_db_index_physical_stat
Mar 6, 2007
Could you help me understand the results of running sys.dm_db_index_physical_stats? select top 10 * from sys.dm_db_index_physical_stats(db_id('web_db1'), OBJECT_ID('tblUser'), NULL, NULL, 'DETAILED');
I see this table. Two HEAP indexes seem to have issues. Shall I simply rebuild the index for this table. How may I convert a table to have a clustered index if it has lots of transactions?

hi, like, if i need to do delete some items with the id = 10000 then also need to update on the remaining items on the with the same idthen i will need to go through all the records to fetch the items with the same id right? so, is there something that i can use to hold those records so that i can do the delete and update just on those records and don't need to query twice? or is there a way to do that in one go ?thanks in advance!
I have four tables: Customer (CustomerId INT, CountyId INT), County (CountyId INT), Search(SearchId INT), and SearchCriteria (SearchCriteriaId INT, SearchId INT, CountyId INT, [others not related to this]).
I want to search Customer based off of the Search record, which could have multiple SearchCriteria records. However, if there aren't any SearchCriteria records with CountyId populated for a given Search, I want it to assume to get all Customer records, regardless of CountyId.
Right now, I'm doing it this way.
DECLARE @SearchId INT = 100 SELECT * FROM Customer WHERE CountyId IN ( SELECT CASE WHEN EXISTS(SELECT CountyId FROM SearchCriteria WHERE SearchId = @SearchId) THEN SearchCriteria.CountyId
[Code] .....
This works; it just seems cludgy. Is there a more elegant way to do this?
Hello. I currently have a website that has a table on one webpage. When a record is clicked, the primary key of that record is transfered in the query string to another page and fed into an sql statement. In this case its selecting a project on the first page, and displaying all the scripts for that project on another page. I also have an additional dropdownlist on the second page that i use to filter the scripts by an attribute called 'testdomain'. At present this works to an extent. When i click a project, i am navigated to the scripts page which is empty except for the dropdownlist. i then select a 'testdomain' from the dropdownlist and the page populates with scripts (formview) for the particular test domain. what i would like is for all the scripts to be displayed using the formview in the first instance when the user arrives at the second page. from there, they can then filter the scripts using the dropdownlist. My current SQL statement is as follows. SelectCommand="SELECT * FROM [TestScript] WHERE (([ProjectID] = @ProjectID) AND ([TestDomain] = @TestDomain))" So what is happening is when testdomain = a null value, it does not select any scripts. Is there a way i can achieve the behaivour of the page as i outlined above? Any help would be appreciated. Thanks, James.

Hi all, I have the following SQLDataSource statement which connects to my Gridview:<asp:SqlDataSource ID="SqlDataSourceStandings" runat="server" ConnectionString="<%$ ConnectionStrings:ConnectionString %>" SelectCommand="SELECT P.firstName, P.lastName, T.teamName, IsNull(P.gamesPlayed, 0) as gamesPlayed, IsNull(P.plateAppearances,0) as plateAppearances, IsNull( (P.plateAppearances - (P.sacrifices + P.walks)) ,0) as atbats, IsNull(P.hits,0) as hits, P.hits/(CONVERT(Decimal(5,2), IsNull(NullIF(P.atbats, 0), 1))) AS [average], (P.hits + P.walks)/(CONVERT(Decimal(5,2), IsNull(NullIF( (P.atbats + P.sacrifices + P.walks) , 0), 1))) AS [OBP], (P.hits - (P.doubles + P.triples + P.homeRuns) + (2 * P.doubles) + (3 * P.triples) + (4 * P.homeRuns)) / (CONVERT(Decimal(5,2), IsNull(NullIF(P.atbats, 0), 1))) AS [SLG], P.singles, P.doubles, P.triples, P.homeRuns, P.walks, P.sacrifices, P.runs, P.rbis FROM Players P INNER JOIN Teams T ON P.team = T.teamID ORDER BY P.firstName, P.lastName"></asp:SqlDataSource>There are 8 teams in the database, and somehow the average and obp results are as expected for all teams except where T.teamID = 1. This doesn't make sense to me at all! For example, I get the following results with this same query: First NameLast NameTeamGPPAABHAVGOBPSLG1B2B3BHRBBSACRRBI
ErikGalvezMelville82625180.7200000.7307691.24000011322101015 As you can see, all teams except for Safe Haven's have the correct AVG and OBP. Since AVG is simply H/AB, it doesn't make sense for Gabriel Helbig's results to be 1.00000. Can anyone shed ANY light on this please?Thank you in advance,Markuu ***As a side note, could anyone also let me know how I could format the output so that AVG and OBP are only 3 decimal places? (ex: 0.719 for the 1st result)***
Hi, I have a web form that lets users search for people in my database they wish to contact. The database returns a paged set of results using a CTE, Top X, and Row_number(). I would like to give my users to option of removing individual people from this list but cannot find a way to do this. I have tried creating a session variable with a comma delimited list of ID's that I pass to my sproc and use in a NOT IN() statement. But I keep getting a "Input string was not in a correct format." Error Message. Is there any way to do this? I am still new to stored procedures so any advice would be helpful. Thanks
Hi, when I copy and paste results from query analyzer into Excel it appears that values with zeroes at the end loose the zeroes. Example, if I copy and paste V128.0 into an Excel cell it comes out as V128 or if I copy 178.70 it displays as 178.7 - any ideas? I'm using SQL Enterprise Manager for 2000.
hi guys, Can anyone advise me how how to read an excel doc i have stored locally? I need to be able to start the read from say row number 6 and finish the read once i get to a row that contains a pre-determined word signifying the end of processing. I intend to store the parsed data in an array that will be used as the data source for a gridview or repeater object on another asp page. I'm using ASP.net 2.0 and C# by the way. thanks in advance for any help!!!
Dim objCon2 As New SqlConnection() objCon2.ConnectionString = "a standard connection string" objCon2.Open()
Dim objCommand As SqlCommand objCommand = New SqlCommand(strSQL, objCon2) Dim objReader As SqlDataReader objReader = objCommand.ExecuteReader()
Label1.Text = objReader("email")
strSQL is a select command which I've checked (using SQL Query analyzer) does return data. I know the connection string is valid (and I presume if it wasn't that it'd fail on objCon2.open, which it doesn't).
So why oh why do I get this error on the last line (and yes, there is an "email" field in the contents of the reader)
System.InvalidOperationException: Invalid attempt to read when no data is present.
I have this code that I hacked together from someone else's example. I kind of understand how it works. I just don't know if it will and i am not in a location right now to check. I was wondering if I did this correctly first, second how can it improve and should i do something different. Basically i just want to check the password in a database. I am passing the username and password to this function from another functioprivate bool authUser(string UserName, string Password){ string connectionString = ConfigurationSettings.AppSettings["DBConnectionString"]; SqlConnection DBConnection = new SqlConnection(connectionString); bool result = false; DBConnection.open() SqlCommand checkCommand = new SqlCommand("SELECT password FROM Users WHERE userName='" + Password + "', DBConnection) SqlDataReader checkDataReader = checkCommand.ExecuteReader(); if(checkDataReader.GetString(0) == Password) { result = true; } else { result = false; } checkDataReader.Close(); DBConnection.Close(); return result;}Thank you Buddy Lindsey
Does anyone know how to read transaction log besides trace and profiler. The current situation is some one in our org. deleted an item and I'm trying to find out who and when.
I have some records that have been deleted. I need to find out who did it and to do that I need to read the logs. Are there any utilities that will allow me to read login 7.0? How about 6.5?
We are having continual problems with our transaction log filling up on one of our major applications. Does anyone know of a way or tool to read the transaction log? We want to determine what is causing this problem.
Is there a way, in SQL 7.0 to print out or view what's in the Transaction Log? In 6.5 you could view the table syslogs, but I don't see any documentation anywhere on how to do this in 7.0.
I received a SQL Server 6.5 database (.dat file) on a removeable drive. I'm currently running 7.0. Is there any way to read/import/link to this data without installing 6.5. And if I have to install 6.5 how do I get the system to see the database?

Hi, I've been a developer for 20 some years, but never learned the design steps of a complex database. Can you give me a book or 2 to bring me up to speed with the latest database design and data modeling techniques?
I do a lot of file processing and I usually run a little script I copyand paste to read directory information to see if a new file it thereand then process the file if it is. So, I decided to wise up and makea stored procedure to automate a lot of that.The pivotal step in this is that i run a command that looks like:CREATE TABLE #DIR (FileName varchar(100))DECLARE @Cmd varchar(1050)SET@Cmd = 'DIR "' + @Path + CASE WHEN RIGHT(@Path, 1) = '' THEN ''ELSE '' END + @WildCard + '"'INSERT INTO #DIREXEC master..xp_CmdShell @CmdWhen I run the stored procedure I get back the files and folders inthere that match the wildcard and all is good!!!!....Until I try to put that information into a table while calling thatstored procedure:CREATE TABLE #Files (Path varchar(100),FileName varchar(100),PathAndFileName varchar(150),FileDateTime SmallDateTime,FileLength int,FileType Varchar(10))INSERT INTO #FilesEXEC sp_GetFileNames @Path = '\isoft2ftpLegacyBilling', @Wildcard= '*.txt'When I run this I get:Server: Msg 8164, Level 16, State 1, Procedure sp_GetFileNames, Line53An INSERT EXEC statement cannot be nested.Because I use an INSERT EXEC to with the results from the @Cmd.Anybody have any ideas how I can get that information into a table?I did try to just copy the data to c: empdir.txt and then bulkimport it in. But when it runs the @Cmd to create the file it comesback with a NULL value and my stored procedure returns two sets ofvalues... which I can't do.So, I would appreciate anybody who can help.Thanks!-utah
I posted this in the Windows Forms Data Binding section, and they directed me to the .Net data section. I posted it there and waited a week with no replies. I'm hoping someone here can at least give me an idea of what the problem might be.
