  • t-sql recursive query

    - by stackoverflowuser
    Based on an existing table I used CTE recursive query to come up with following data. But failing to apply it a level further. Data is as below id name parentid -------------------------- 1 project 0 2 structure 1 3 path_1 2 4 path_2 2 5 path_3 2 6 path_4 3 7 path_5 4 8 path_6 5 I want to recursively form full paths from the above data. Means the recursion will give the following output. FullPaths ------------- Project Project\Structure Project\Structure\Path_1 Project\Structure\Path_2 Project\Structure\Path_3 Project\Structure\Path_1\path_4 Project\Structure\Path_2\path_5 Project\Structure\Path_3\path_6 Thanks

  • SQL Server Express performance issue

    - by Developer IT
    Hi folks ! I know my questions will sound silly and probably nobody will have perfect answer but since I am in a complete dead-end with the situation it will make me feel better to post it here. So... I have a SQL Server Express database that's 500 Mb. It contains 5 tables and maybe 30 stored procedure. This database is use to store articles and is use for the Developer It web site. Normally the web pages load quickly, let's say 2 ou 3 sec. BUT, sqlserver process uses 100% of the processor for those 2 or 3 sec. I try to find which stored procedure was the problem and I could not find one. It seems like every read into the table dans contains the articles (there are about 155,000 of them and 20 or so gets added every 15 minutes). I added few index but without luck... It is because the table is full text indexed ? Should I have order with the primary key instead of date ? I never had any problems with ordering by dates.... Should I use dynamic SQL ? Should I add the primary key into the url of the articles ? Should I use mutiple indexes for seperate columns or one big index ? I you want more details or code bits, just ask for it. Basicly, every little hint is much apreciated. Thanks.

  • Computed column should result to string

    - by strakastroukas
    Here is a snap of my database. Both col1 and col2 are declared as int. My ComputedColumn currently adds the Columns 1 and 2, as follows... col1 col2 ComputedColumn 1 2 3 4 1 5 Instead of this, my ComputedColumn should join the columns 1 and 2 (includimg the '-' character in the middle) as follows... col1 col2 ComputedColumn 1 2 1-2 4 1 4-1 So, what is the correct syntax?

  • APplication performance issue : SqlServer & Oracle

    - by Mahesh
    Hi, We have a applicaiton in Silverlight,WCF, NHibernate. Currently it is supporting SQL Serve and Oracle database. As it's huge data, it is running ok on SQL Sevrer. But on Oracle it is running very slow. For one functionality it takes 5 Sec to execute on SQL Server and 30 Sec on Oracle. I am not able to figure out what will be issue. Two things that i want to share with you about our database. 1) Database: contains one base table contains column of type SQLServer: [Text] Oracle: [NCLOB] 2) Our database structure is too much normalized. May be in the oracle i have used NCLOB, that is the cause of the performance. I mean i don't know the details about it.... Can anyone please let me know what will be cause? Or Which actions do i need to follw to improve the performance as equal as SqlServer.? Thanks in advance. Mahesh.

  • Different execution plan for similar queries

    - by Graham Clements
    I am running two very similar update queries but for a reason unknown to me they are using completely different execution plans. Normally this wouldn't be a problem but they are both updating exactly the same amount of rows but one is using an execution plan that is far inferior to the other, 4 secs vs 2 mins, when scaled up this is causing me a massive problem. The only difference between the two queries is one is using the column CLI and the other DLI. These columns are exactly the same datatype, and are both indexed exactly the same, but for the DLI query execution plan, the index is not used. Any help as to why this is happening is much appreciated. -- Query 1 UPDATE a SET DestKey = ( SELECT TOP 1 b.PrefixKey FROM refPrefixDetail AS b WHERE a.DLI LIKE b.Prefix + '%' ORDER BY len(b.Prefix) DESC ) FROM CallData AS a -- Query 2 UPDATE a SET DestKey = ( SELECT TOP 1 b.PrefixKey FROM refPrefixDetail b WHERE a.CLI LIKE b.Prefix + '%' ORDER BY len(b.Prefix) DESC ) FROM CallData AS a

  • Use SQL to filter the results of a stored procedure

    - by Ben McCormack
    I've looked at other questions on Stack Overflow related to this question, but none of them seemed to answer this question clearly. We have a system Stored Procedure called sp_who2 which returns a result set of information for all running processes on the server. I want to filter the data returned by the stored procedure; conceptually, I might do it like so: SELECT * FROM sp_who2 WHERE login='bmccormack' That method, though, doesn't work. What are good practices for achieving the goal of querying the returned data of a stored procedure, preferably without having to look of the code of the original stored procedure and modify it.

  • T-SQL error object exists when separated in if/else blocks

    - by Jeff O
    I get the error: Msg 2714, Level 16, State 1, Line 16 There is already an object named '#mytemptable' in the database. There are ways around it, but wonder why this happens. Seems like SQL Server is verifying both blocks of the if/else statement? declare @choice int select @choice = 1 if @choice = 1 begin select 'MyValue = 1' AS Pick into #my_temp_table end else begin select 'MyValue <> 1' AS Pick into #my_temp_table end select * from #temptable drop table #temptable If the tables have different names, it works. Or if I create the temp table and use Insert Into... statements that works as well.

  • How can I iterate over a recordset within a stored procedure?

    - by David
    I need to iterate over a recordset from a stored procedure and execute another stored procedure using each fields as arguments. I can't complete this iteration in the code. I have found samples on the internets, but they all seem to deal with a counter. I'm not sure if my problem involved a counter. I need the T-SQL equivalent of a foreach Currently, my first stored procedure stores its recordset in a temp table, #mytemp. I assume I will call the secondary stored procedure like this: while (something) execute nameofstoredprocedure arg1, arg2, arg3 end

  • Linq to sql Incorrect varchar length

    - by scott
    I have a table with a nullable varchar(50) column in it. When I am updating the value through linq to sql and trace the call in profiler it is defining the parameter as varchar(36). This is obviously causing some minor issues when we are trying to insert data that is between 37 and 50 characters long. I have tried removing the table and re-adding it to the design surface but the same thing happens. I also tried removing that property and adding it manually, same issue. When I look at the designer.cs code it shows the attribute properly: [Column(Storage="_Name", DbType="VarChar(50)")] I am out of ideas, anybody seen this before? Every other column is correct.

  • Power error handling inside of sql function

    - by user172062
    I have a power function call inside of a sql function. What is the correct way to handle overflow and underflow conditions since I cannot use a Try Catch inside of a function. I am also trying to avoid modifying the ARITHABORT, ANSI_WARNINGS, and ARITHIGNORE settings in the calling code. GO CREATE FUNCTION TestPow() RETURNS DECIMAL(30, 14) AS BEGIN DECLARE @result FLOAT SET @result = POWER(10.0, 300) RETURN @result END GO SELECT dbo.TestPow()

  • Detecting if SQL Server Compact Edition 3.5 SP2 x64 is installed?

    - by Nate Zaugg
    I am building an installer and I want to bootstrap SQL Server Compact Edition 3.5 SP2. The problem is that I am looking for the registry key HKLM\SOFTWARE\Microsoft\Microsoft SQL Server Compact Edition\v3.5\ENU\DesktopRuntimeVersion. The reason that is a problem is that for 64-bit machines SQL CE requires that both the 32-bit and 64-bit installers are run. You can't install the 64-bit version until the 32-bit version is installed. As soon as the 32-bit version is installed the registry key is populated and my bootstrapper, dotNetInstaller detects that the registry key is there and the x64 version is never installed. Any ideas on how to tell if the x64 version is installed even if the x32 is installed?

  • Pointer incrementing query

    - by Craig
    I have been looking at this piece of code, and it is not doing what I expect. I have 3 globals. int x, y, *pointer, z; Inside of main I declare them. x = 10; y = 25; pointer = &x; now at this point &x is 0x004A144 &y is 0x004A138 pointer is pointing to 0x004A144 Now when I increment: y = *++pointer; it points to 0x004A148, this is the address y should be at shouldn't it? The idea is that incrementing the pointer to 'x' should increment it to point at y, but it doesn't seem to want to declare them in in order like I expect. If this a VS2005 / 2008 problem? Or maybe an Express problem? This isn't really homework, as I have done it a couple of years ago but I was revising on my pointer stuff and I tried this again. But this time I am getting unexpected results. Does anyone have opinions on this? *UPDATE sorry should be more clear, 'thought' on declaration 'y' should be at 148, and that incrementing the pointer pointing to x should increment 'pointer' to 148 (which it does), but that isn't where y is. Why isn't y declaring where it should be.

  • SQL Server: How to remove empty lines in SSMS?

    - by atricapilla
    I have many .sql files with lots of empty lines e.g. WITH cteTotalSales (SalesPersonID, NetSales) AS ( SELECT SalesPersonID, ROUND(SUM(SubTotal), 2) FROM Sales.SalesOrderHeader WHERE SalesPersonID IS NOT NULL GROUP BY SalesPersonID ) SELECT sp.FirstName + ' ' + sp.LastName AS FullName, sp.City + ', ' + StateProvinceName AS Location, ts.NetSales FROM Sales.vSalesPerson AS sp INNER JOIN cteTotalSales AS ts ON sp.BusinessEntityID = ts.SalesPersonID ORDER BY ts.NetSales DESC Is ther a way to remove these empty lines in SQL Server Management Studio? This is what I would like to have: WITH cteTotalSales (SalesPersonID, NetSales) AS ( SELECT SalesPersonID, ROUND(SUM(SubTotal), 2) FROM Sales.SalesOrderHeader WHERE SalesPersonID IS NOT NULL GROUP BY SalesPersonID ) SELECT sp.FirstName + ' ' + sp.LastName AS FullName, sp.City + ', ' + StateProvinceName AS Location, ts.NetSales FROM Sales.vSalesPerson AS sp INNER JOIN cteTotalSales AS ts ON sp.BusinessEntityID = ts.SalesPersonID ORDER BY ts.NetSales DESC

  • Fastest way to compress a database or .bak file and transfer it

    - by Nai
    As per the question title. I wonder if there are special programmes or commands that makes zipping up a .bak file and transferring it super quick. I read abour xp_cmdshell here but I'm not sure about the speed. My .bak file is about 12 gigs at the moment. Related to this is the possibility of using Red Gate's SQL Data Compare to just transfer the differential data across the network pipeline but I have never used SQL Data Compare before and I'm not sure how it goes about doing INSERTS on tables with Primary Keys and such. Also, not sure about the speed. Does anyone have any experience with this programme or similar programmes? Cheers!

  • Unable to create PDB file

    - by Ryan Smith
    For some reason this error started popping up today on one of my projects. Error 1 Unable to write to output file 'C:\MyProject\Release\MyProject.pdb': Unspecified error If I go into advanced compile options and change it to not generate and debug info, my project compiles fine. I have tried setting the permissions on the Release folder to full for everyone, so I would assume it's not a permissions issue. Also, I don't see anything in my log files that would provide me with more information about the issue. Does anyone know why this error would just start showing up or a way to fix it? Thanks. Update: I have rebooted my machine, restarted VS several times and have even completely deleted the existing OBJ file where the issue is happening. It's still giving me the same error. This is a simple one project solution that was working fine just last week. It appears to be an issue with VS trying to build the PDB file because I can delete them out of the Release and Debug folders without issue. When I try rebuilding them VS will start creating the file (about 1.4MB is size) but I still get the error.

  • Create view or SP, only if the DB contains a pattern

    - by Randall Salas
    Hi all: I am working on a script, that needs to be run in many different SQL servers. Some of them, shared the same structure, in other words, they are identical, but the filegroups and the DB names are different. This is because is one per client. Anyway, I would like when running a script, If I chose the wrong DB, it should not be executed. I am trying to mantain a clean DB. here is my example, which only works for dropping a view if exists, but does not work for creating a new one. I also wonder how it would be for creating a stored procedure. Thx a lot. if exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[ContentModDate]') and OBJECTPROPERTY(id, N'IsView') = 1) AND CHARINDEX('Content', DB_NAME()) 0 drop view [dbo].[ContentModDate] GO IF (CHARINDEX('Content', DB_NAME()) 0)BEGIN CREATE VIEW [dbo].[Rx_ContentModDate] AS SELECT 'Table1' AS TableName, MAX(ModDate) AS ModDate FROM Tabl1 WHERE ModDate IS NOT NULL UNION SELECT 'Table2', MAX(ModDate) AS ModDate FROM Table2 WHERE ModDate IS NOT NULL END END GO
