• I cannot connect to SQL Server Express using VB.NET

  - by konin

  Can someone tell me what I am missing? I am using this connection string to connect to my database and still it won't connect: Dim str As String = "Provider = .NET Framework Data Provider for SQL Server; Data Source=C:\Users\konin\Documents\UHMS\bin\Debug\UHMS.mdf;Integrated Security=True;Connect Timeout=30;User Instance=True" This is the process I used to get the data source: right-click the database select properties and click select data source I hope I am clear enough. Thanks for reading. Edit: Error Message is as follows: unable to connect to database please contact administrator

• Sql Server SMO connection timeout not working

  - by Uros Calakovic

  I have the following PowerShell code: function Get-SmoConnection { param ([string] $serverName = "", [int] $connectionTimeout = 0) if($serverName.Length -eq 0) { $serverConnection = New-Object ` Microsoft.SqlServer.Management.Common.ServerConnection } else { $serverConnection = New-Object ` Microsoft.SqlServer.Management.Common.ServerConnection($serverName) } if($connectionTimeout -ne 0) { $serverConnection.ConnectTimeout = $connectionTimeout } try { $serverConnection.Connect() $serverConnection } catch [system.Management.Automation.MethodInvocationException] { $null } } $connection = get-smoconnection "ServerName" 2 if($connection -ne $null) { Write-Host $connection.ServerInstance Write-Host $connection.ConnectTimeout } else { Write-Host "Connection could not be established" } It seems to work, except for the part that attempts to set the SMO connection timeout. If the connection is successful, I can verify that ServerConnection.ConnectTimeout is set to 2 (seconds), but when I supply a bogus name for the SQL Server instance, it still attempts to connect to it for ~ 15 seconds (which is I believe the default timeout value). Does anyone have experience with setting SMO connection timeout? Thank you in advance.

• Why better isolation level means better performance in SQL Server

  - by Oleg Zhylin

  When measuring performance on my query I came up with a dependency between isolation level and elapsed time that was surprising to me READUNCOMMITTED - 409024 READCOMMITTED - 368021 REPEATABLEREAD - 358019 SERIALIZABLE - 348019 Left column is table hint, and the right column is elapsed time in microseconds (sys.dm_exec_query_stats.total_elapsed_time). Why better isolation level gives better performance? This is a development machine and no concurrency whatsoever happens. I would expect READUNCOMMITTED to be the fasted due to less locking overhead. Update: I did measure this with DBCC DROPCLEANBUFFERS DBCC FREEPROCCACHE issued and Profiler confirms there're no cache hits happening. Update2: The query in question is an OLAP one and we need to run it as fast as possible. Closing the production server from outside world to get the computation done is not out of question if this gives performance benefits.

• Query to return internal details about stored function in SQL Server database

  - by Anthony

  I have been given access to a SQL Server database that is currently used by 3rd party app. As such, I don't have any documentation on how that application stores the data or how it retrieves it. I can figure a few things out based on the names of various tables and the parameters that the user-defined functions takes and returns, but I'm still getting errors at every other turn. I was thinking that it would be really helpful if I could see what the stored functions were doing with the parameters given to return the output. Right now all I've been able to figure out is how to query for the input parameters and the output columns. Is there any built-in information_schema table that will expose what the function is doing between input and output?

• I need a query designed for MySQL translated to work for SQL Server 2005

  - by brookmarker

  I've spent a whole day on this already without figuring it out. I'm hoping somebody can help me translate the following MySQL query to work for SQL Server 2005: SELECT MAX ( messages.date ) AS maxdate, topics.id AS topicid, topics.*, users.* FROM messages, topics, users WHERE messages.topic_id = topics.id AND topics.user_id = users.id AND topics.forum_id = " . $forumid . " GROUP BY messages.topic_id ORDER BY maxdate DESC $forumid is a QueryString value defined in the following VB.NET code-behind code: forumName.Text = "<a href='ViewForum.aspx?forumid=" & row.id & "'>" & row.name & "</a>" I'd be super grateful if u can help.

• How to use correctly the Query Window in SQL Server 2008

  - by Richard77

  Hello, What should I do to avoid that commands be executed each time I hit 'Execute !. icon' I mean this USE master; GO CREATE DATABASE Sales GO USE Sales; GO CREATE TABLE Customers( CustomerID int NOT NULL, LName varchar (50) NOT NULL, FName varchar (50) NULL, Status varchar (10), ModifiedBy varchar (30) NULL ) GO When I click Execute!, Sql Server tries to redo the same thing. What I do for now is to delete the Query Window completely then write what I need before clicking the Execute icon. But, I doubt that I should be doing that. What can I do to keep writing the commands without having each time to clear the Query Window? Thanks for helping

• SQL Server, Remote Stored Procedure, and DTC Transactions

  - by marc

  Our organization has a lot of its essential data in a mainframe Adabas database. We have ODBC access to this data and from C# have queried/updated it successfully using ODBC/Natural "stored procedures". What we'd like to be able to do now is to query a mainframe table from within SQL Server 2005 stored procs, dump the results into a table variable, massage it, and join the result with native SQL data as a result set. The execution of the Natural proc from SQL works fine when we're just selecting it; however, when we insert the result into a table variable SQL seems to be starting a distributed transaction that in turn seems to be wreaking havoc with our connections. Given that we're not performing updates, is it possible to turn off this DTC-escalation behavior? Any tips on getting DTC set up properly to talk to DataDirect's (formerly Neon Systems) Shadow ODBC driver?

• JQuery post not working when moving web-app to a win server 2003

  - by karl

  I have build a webapplication using ASP.NET MVC and JQuery. On my local machine this works fine,but when moving it to a Windows server 2003 the JQuery method post stops working. I'm also using the load method and this works fine. function methodOne(id) { alert("debug1: <%= Url.Action( "MethodOne", "controller" ) + "/" %>" + id); $.post <%= Url.Action( "MethodOne", "controller" ) + "/" %>" + id, function(data) { alert("debug2"); ... } else { alert("Debugg: Add presentation to user failed"); } }); } The debug2 is never outputed. $('#panel').load("<%= Url.Action( "Method", "Controller" ) %"); Works fine.

• Pear MDB2 class and raiserror exceptions in SQL Server

  - by drholzmichl

  Hi, in SQL Server it's possible to raise an error with raiserror(). I want to use a severity, which doesn't interrupt the connection. This error is raised in a stored procedure. In SQL Management Studio all is fine and I get my error code when executing this SP. But when trying to execute this SP via MDB2 in PHP5 this doesn't work. All I get is an empty array. MDB2 object is created via (including needed options): $db =& MDB2::connect($dsn); $db->setFetchMode(MDB2_FETCHMODE_ASSOC); $db->setOption('portability',MDB2_PORTABILITY_ALL ^ MDB2_PORTABILITY_EMPTY_TO_NULL); The following works (I get a PEAR error): $db->query("RAISERROR('test',11,0);"); But when calling a stored procedure which raises this error via $db->query("EXEC sp_raise_error"); there is not output. What's wrong?

• PLESK direct www.domain.com to another server with a unique IP

  - by Cudos

  Hello. I got a customer where I host mail and www address on my server with PLESK 9.2 I want to direct the www address to another IP address like this: Original: www.domain.com -> IP: 1.2.3.4 mail.domain.com -> IP: 1.2.3.4 webmail.domain.com -> IP: 1.2.3.4 New: www.domain.com -> IP: 22.22.22.22 mail.domain.com -> IP: 1.2.3.4 webmail.domain.com -> IP: 1.2.3.4

• Fatal Error when using ADODB in VB6 on Windows Server 2003 SP2

  - by m.edmondson

  We've got a legacy app (VB6) which works fine on an old Windows Server 2003 box and has been for many years. Recently we've had to move it to a different physical location and in doing this we cloned the box with virtualisation and placed it elsewhere. In theory these two environments should be identical. On the new box however the app falls over when calling the RecordCount method of an ADODB.Recordset. I should say that I can successfully read the ADODB.RecordSet.Properties.Count property with no problem on the line before. The event viewer reports the following: Event Type: Error Event Source: Application Error Event Category: (100) Event ID: 1000 Date: 28/09/2012 Time: 11:15:27 User: N/A Computer: APP01 Description: Faulting application Control.exe, version 1.0.0.6, faulting module ntdll.dll, version 5.2.3790.4789, fault address 0x0002c6e4. I can only imagine there is something wrong with using ADODB within a virtualised environment. Any ideas?

• Obtain Update Table Lock at start of Stored Procedure in SQL Server

  - by Jim Hurne

  I'm writing a SQL Server stored procedure in which I want to lock a table for update before executing the body of the stored procedure. I don't want to prevent other processes from reading the table, but I do want to prevent other processes updating the table. Here is my first attempt: CREATE PROCEDURE someProcedure BEGIN SET TRANSACTION ISOLATION LEVEL READ COMITTED BEGIN TRANSANCTION SELECT COUNT(*) FROM TheTable WITH (UPDLOCK, TABLOCK) -- Pause procedure so that we can view the locks with sp_lock WAITFOR DELAY '00:15' -- Do stuff COMMIT END When I execute the stored procedure, and invoke sp_lock, I see that the table is indeed locked. However, it's locked with an Exclusive lock instead of an update lock: spid | dbid | ObjId | IndId | Type | Resource | Mode | Status ------------------------------------------------------------------ 63 | 10 | 233208031 | 0 | TAB | | X | GRANT How can I get an update (U) lock instead?

• ASP.NET MVC Deployed Application Server Address

  - by Jacob Huggart

  I have an application that sends an email to a user so that they may access a web form. In the email there is just a link to the start page of this form. Currently, I have the value for the form location hardcoded. Once the app is deployed I know it is in inetpub/wwwroot/appName, which results in a URL of serverip:appPort/appName. What is the C# to get the serverip:appPort portion of the URL that I need? I think that server.mappath() might work, but for some reason I can't get to the method even though I have the necessary references.

• List of all index & index columns in SQL Server DB

  - by Anton Gogolev

  How do I get a list of all index & index columns in SQL Server 2005+? The closest I could get is: select s.name, t.name, i.name, c.name from sys.tables t inner join sys.schemas s on t.schema_id = s.schema_id inner join sys.indexes i on i.object_id = t.object_id inner join sys.index_columns ic on ic.object_id = t.object_id inner join sys.columns c on c.object_id = t.object_id and ic.column_id = c.column_id where i.index_id > 0 and i.type in (1, 2) -- clustered & nonclustered only and i.is_primary_key = 0 -- do not include PK indexes and i.is_unique_constraint = 0 -- do not include UQ and i.is_disabled = 0 and i.is_hypothetical = 0 and ic.key_ordinal > 0 order by ic.key_ordinal which is not exactly what I want. What I want is to list all user-defined indexes (which means no indexes which support unique constraints & primary keys) with all columns (ordered by how do they apper in index definition) plus as much metadata as possible.

• DataReader Behaviour With SQL Server Locking

  - by Graham

  We are having some issues with our data layer when large datasets are returned from a SQL server query via a DataReader. As we use the DataReader to populate business objects and serialize them back to the client, the fetch can take several minutes (we are showing progress to the user :-)), but we've found that there's some pretty hard-core locking going on on the affected tables which is causing other updates to be blocked. So I guess my slightly naive question is, at what point are the locks which are taken out as a result of executing the query actually relinquished? We seem to be finding that the locks are remaining until the last row of the DataReader has been processed and the DataReader is actually closed - does that seem correct? A quick 101 on how the DataReader works behind the scenes would be great as I've struggled to find any decent information on it. I should say that I realise the locking issues are the main concern but I'm just concerned with the behaviour of the DataReader here.

• What to monitor on MSSQL Server

  - by user361434

  Hi all I have been asked to monitor MSSQL Server (2005 & 2008) and am wondering what are good metrics to look at? I can access WMI counters but am slightly lost as to how much depth is going to be useful. Currently I have on my list: user connections logins per second latch waits per second total latch wait time dead locks per second errors per second Log and data file sizes I am looking to be able to monitor values that will indicate a degradation of performance on the machine or a potential serious issue. To this end I am also wondering at what values some of these things would be considered normal vs problematic? As I reckon it would probably be a really good question to have answered for the general community I thought i'd court some of you DBA experts out there (I am certainly not one of them!) Apologies if a rather open ended question. Ry

• Solving a SQL Server Deadlock situation

  - by mjh41

  I am trying to find a solution that will resolve a recurring deadlock situation in SQL server. I have done some analysis on the deadlock graph generated by the profiler trace and have come up with this information: The first process (spid 58) is running this query: UPDATE cds.dbo.task_core SET nstate = 1 WHERE nmboxid = 89 AND ndrawerid = 1 AND nobjectid IN (SELECT nobjectid FROM ( SELECT nobjectid, count(nobjectid) AS counting FROM cds.dbo.task_core GROUP BY nobjectid) task_groups WHERE task_groups.counting > 1) The second process (spid 86) is running this query: INSERT INTO task_core (…) VALUES (…) spid 58 is waiting for a Shared Page lock on CDS.dbo.task_core (spid 86 holds a conflicting intent exclusive (IX) lock) spid 86 is waiting for an Intent Exclusive (IX) page lock on CDS.dbo.task_core (spid 58 holds a conflicting Update lock)

• SQL Server - Compare int values in a select clause

  - by Russell

  This is what I thought would be a simple select clause, however the following is giving me grief! I am using SQL Server 2008. Basically I want to compare two integer values and return the boolean result in the select clause. Here is a simple example: DECLARE @A INT DECLARE @B INT SET @A = 1 SET @B = 2 SELECT @A = @B Currently the only output is "Command(s) completed successfully." Where I reasonably believe it is assigning @A to @B. I thought this would be simple but have not been able to achieve this. Any help would be great! Thanks

• SQL Server T-SQL statement to replace/delete sub-strings

  - by StefanE

  Hi, I have a table with 6 columns containing HTML content with some markups in it and now when moving to a new designed site most of this HTML code has to be deleted. More or less all tags except <B> and </B>. Is there a nice way of doing this, identify all tags end delete them within the data? I'm sure there are no < symbols in the test so a regular expression would maybe work? My alternative is to fetch every row, process it and update the database but I'm guessing this is possible to do in T-SQL directly. My server is an MSSQL 2008 and is located in a hosted environment but I can fetch a local copy if needed. Thanks, Stefan

• 'Out of Memory exception' in sql server 2005 xml column

  - by Raghuraman

  Hi All, I am devloping a windows forms application and am using sql server 2005 database as my backend. I am having an xml column in my database. I am using ultrawingrid control in my application.I obtain the xml of the dataset which is bound to my ultrawingrid control and pass that as a parameter value to the stored procedure where am inserting this value into the xml column which I specified. The columns in my grid are dynamic and hence there can be any no of columns in my grid. I got 'out of memory' exception in the dataset.GetXml() statement since there were more no of columns I believe.So, what I did is that I used dataset.WriteXml() method and stored all the xml contents into an xml file, loaded the xml file into the XmlDocument object and then passed the xmlnodereader as the value to the stored procedure parameter.Now, while executing the stored procedure am getting the same 'out of memory' exception. How could I resolve this issue?

• ASP.NET and SQL server with huge data sets

  - by Jake Petroules

  I am developing a web application in ASP.NET and on one page I am using a ListView with paging. As a test I populated the table it draws from with 6 million rows. The table and a schema-bound view based off it have all the necessary indexes and executing the query in SQL Server Management Studio with SELECT TOP 5 returned in < 1 second as expected. But on the ASP.NET page, with the same query, it seems to be selecting all 6 million rows without any limit. Shouldn't the paging control limit the query to return only N rows rather than the entire data set? How can I use these ASP.NET controls to handle huge data sets with millions of records? Does SELECT [columns] FROM [tablename] quite literally mean that for the ListView, and it doesn't actually inject a TOP <n> and does all the pagination at the application level rather than the database level?

• SQL Server Import table keeping default values

  - by Chrissi

  I am importing a table from one database to another in SQL Server 2008 by right-clicking the target database and choosing Tasks Import Data... When I import the table I get the column names and types and all the data fine, but I lose the primary key, identity specifications and all the default values that were set in the source table. So now I have to set all the default values for each column again manually. Is there any way to get the default values with the import, or even after with a Query? I am VERY new to this and flailing in the dark, so forgive me if this is a really stupid question...

• SQL Server 2008 - Search Query

  - by user208662

  Hello, I am not a SQL Expert. I’m trying to elegantly solve a query problem that others have had to have had. Surprisingly, Google is not returning anything that is helping. Basically, my application has a “search” box. This search field will allow a user to search for customers in the system. I have a table called “Customer” in my SQL Server 2008 database. This table is defined as follows: Customer UserName (nvarchar) FirstName (nvarchar) LastName (nvarchar) As you can imagine, my users will enter queries of varying cases and probably mis-spell the customer’s names regularly. How do I query my customer table and return the 25 results that are closest to their query? I have no idea how to do this ranking and consider the three fields listed in my table. Thank you!

• Using [delphi] MadExcept errorhandling with MS Echange Server 2007

  - by Tony

  I currently use madExcept.MailAsSmtpClient to send my bug reports. However a couple of large clients have upgraded to Exchange Server 2007 and we can't get the SMTP support for our app configured (the app runs on individual workstations so the messages aren't all coming from one IP. We can configure an authenticated account in exchange and access it via SMTP from other clients but it rejects madExcept for some reason). So I have two questions 1) has anyone successfully configured that combo ? or 2) is there an example somewhere of how to use the madExcept.UploadViaHTTP option?

• How to use a variable to specify filegroup in SQL Server

  - by gt

  I want to alter a table to add a constraint during upgrade on a SQL Server database. This table is normally indexed on a filegroup called 'MY_INDEX' - but may also be on a database without this filegroup. In this case I want the indexing to be done on the 'PRIMARY' filegroup. I tried the following code to achieve this: DECLARE @fgName AS VARCHAR(10) SET @fgName = CASE WHEN EXISTS(SELECT groupname FROM sysfilegroups WHERE groupname = 'MY_INDEX') THEN QUOTENAME('MY_INDEX') ELSE QUOTENAME('PRIMARY') END ALTER TABLE [dbo].[mytable] ADD CONSTRAINT [PK_mytable] PRIMARY KEY ( [myGuid] ASC ) ON @fgName -- fails: 'incorrect syntax' However, the last line fails as it appears a filegroup cannot be specified by variable. Is this possible?
