  • Trying to verify understanding of foreign keys SQL Server

    - by msarchet
    So I'm working on just a learning project to expose myself to doing some things I do not get to do at work. I'm just making a simple bug and case tracking app (I know there are a million this is just to work with some tools I don't get to). So I was designing my database and realized I've never actually used Foreign Keys before in any of my projects, I've used them before but never actually setting up a column as a FK. So I've designed my database as follows, which I think is close to correct (at least for the initial layout). However When I try to add the FK's to the linking Tables I get an error saying, "The tables present in the relationship must have the same number of columns". I'm doing this by in SQLSMS by going to the Keys 'folder' and adding a FK. Is there something that I am doing wrong here, I don't understand why the tables would have to have the same number of columns for me to add a FK relationship between the tables?

  • .NET and Closing SQL Server connections

    - by user307076
    I am having a hard time figuring out why the following constructor will not close connnections. When I view the active connections. Here is the code that I have.

  • varchar comparison in SQL Server

    - by Ram
    I am looking for some SQL varchar comparison function like C# string.compare (we can ignore case for now, should return zero when the character expression are same and a non zero expression when they are different) Basically I have some alphanumeric column in one table which needs to be verified in another table. I cannot do select A.col1 - B.col1 from (query) as "-" operator cannot be applied on character expressions I cannot cast my expression as int (and then do a difference/subtraction) as it fails select cast ('ASXT000R' as int) Conversion failed when converting varchar 'ASXT000R' to int Soundex would not do it as soundex is same for 2 similar strings Difference would not do it as select difference('abc','ABC') = 4 (as per msdn, difference is the difference in the soundex of 2 character expressions and difference =4 implies least different) Is there any other way of doing it ?

  • similarity between strings - sql server 2005

    - by csetzkorn
    Hi, I am looking for a simple way (UDF?) to establish the similarity between strings. The SOUNDEX and DIFFERENCE function do not seem to do the job. Similarity should be based on number of characters in common (order matters). For example: Spiruroidea sp. AM-2008 and Spiruroidea gen. sp. AM-2008 should be recognised as similar. Any pointers would be very much appreciated. Thanks. Christian

  • Sql Server Maintenance Plan Tasks & Completion

    - by Ben
    Hi All, I have a maintenance plan that looks like this... Client 1 Import Data (Success) -> Process Data (Success) -> Post Process (Completion) -> Next Client Client 2 Import Data (Success) -> Process Data (Success) -> Post Process (Completion) -> Next Client Client N ... Import Data and Process Data are calling jobs and Post Process is an Execute Sql task. If Import Data or Process Data Fail, it goes to the next client Import Data... Both Import Data and Process Data are jobs that contain SSIS packages that are using the built-in SQL logging provider. My expectation with the configuration as it stands is: Client 1 Import Data Runs: Failure - Client 2 Import Data | Success Process Data Process Data Runs: Failure - Client 2 Import Data | Success Post Process Post Process Runs: Completion - Success or Failure - Next Client Import Data This isn't what I'm seeing in my logs though... I see several Client Import Data SSIS log entries, then several Post Process log entries, then back to Client Import Data! Arg!! What am I doing wrong? I didn't think the "success" piece of Client 1 Import Data would kick off until it... well... succeeded aka finished! The logs seem to indicate otherwise though... I really need these tasks to be consecutive not concurrent. Is this possible? Thanks!

  • Which can handle a huge surge of queries: SQL Server 2008 Fulltext or Lucene

    - by Luke101
    I am creating a widget that will be installed on several websites and blogs. The widget will analyse the remote webpage title and content, then it will return relevent articles/links on my website. The amount of traffic we expect will be very huge roughly 500K queries a day and up from there. I need the queries to be returned very quickly, so I need the candidate to be high performance, similar to google adsense. The remote title can be from 5 to 50 words and the description we will use no more then 3000 words. Which of these two do you think can handle the load.

  • Reporting Services SQL Server 2005 File Share Error

    - by NicholasM
    Hi, I have a problem with Reporting Services, on an XP box, trying to save subscription reports onto a Windows 7 box over the network. No matter the permissions or accounts used by reporting services it always comes back with "A logon error occurred when attempting to access the file share. The user account or password is not valid." Since this is saving reports over the network and both admin accounts and open network/file permissions to everyone were both tried so I'm left wondering if this is an issue with Reporting Services 2005 has troubles with Windows 7 over the network. Any help would be appreciated, Thanks.

  • find rows that fall between a day and time of the week in sql server

    - by Corgalore
    I have a table of rows in MS SQL that contain a start and end day of the week, hour, and time. I need a T-SQL query that can pull rows from that table where GETDATE matches the day of week and time of those rows. Specifically, I need the query to work if a row has a day/time that starts on one day of the week and ends on the next day. Here's the structure I'm working with: _start_day_of_week (int) = 5_start_hour (int) = 15_start_minute (int) = 30 _end_day_of_week (int) = 6_end_hour (int) = 2 _end_minute (int) = 30 _title (string) = 'My Sample Row' _id (int) = 1 How would I retrieve this row given the current DATETIME?

  • Copy whole SQL Server database into JSON from Python

    - by Oli
    I facing an atypical conversion problem. About a decade ago I coded up a large site in ASP. Over the years this turned into ASP.NET but kept the same database. I've just re-done the site in Django and I've copied all the core data but before I cancel my account with the host, I need to make sure I've got a long-term backup of the data so if it turns out I'm missing something, I can copy it from a local copy. To complicate matters, I no longer have Windows. I moved to Ubuntu on all my machines some time back. I could ask the host to send me a backup but having no access to a machine with MSSQL, I wouldn't be able to use that if I needed to. So I'm looking for something that does: db = {} for table in database: db[table.name] = [row for row in table] And then I could serialize db off somewhere for later consumption... But how do I do the table iteration? Is there an easier way to do all of this? Can MSSQL do a cross-platform SQLDump (inc data)? For previous MSSQL I've used pymssql but I don't know how to iterate the tables and copy rows (ideally with column headers so I can tell what the data is). I'm not looking for much code but I need a poke in the right direction.

  • What should I do with syncobj in SQL Server

    - by hgulyan
    Hi. I run this script to search particular text in sys.columns and I get a lot of "dbo.syncobj_0x3934443438443332" this kind of result. SELECT c.name, s.name + '.' + o.name FROM sys.columns c INNER JOIN sys.objects o ON c.object_id=o.object_id INNER JOIN sys.schemas s ON o.schema_id=s.schema_id WHERE c.name LIKE '%text%' If I get it right, they are replication objects. Is it so? Can i just throw them away from my query just like o.name NOT LIKE '%syncobj%' or there's another way? Thank you.

  • SQL Server: Are temp tables or unions better?

    - by Jonathan Allen
    Generally speaking, for combining a lot of data is it better to use a temp table/temp variable as a staging area or should I just stick to "UNION ALL"? Assumptions: No further processing is needed, the results are sent directly to the client. The client waits for the complete recordset, so streaming results isn't necessary.

  • SQL Server view: how to add missing rows using interpolation

    - by Christopher Klein
    Running into a problem. I have a table defined to hold the values of the daily treasury yield curve. It's a pretty simple table used for historical lookup of values. There are notibly some gaps in the table on year 4, 6, 8, 9, 11-19 and 21-29. The formula is pretty simple in that to calculate year 4 it's 0.5*Year3Value + 0.5*Year5Value. The problem is how can I write a VIEW that can return the missing years? I could probably do it in a stored procedure but the end result needs to be a view.

  • Test-First development tool for SQL Server 2005?

    - by Jeff Jones
    For several years I have been using a testing tool called qmTest that allows me to do test-driven database development for some Firebird databases. I write a test for a new feature (table, trigger, stored procedure, etc.) until it fails, then modify the database until the test passes. If necessary, I do more work on the test until it fails again, then modify the database until the test passes. Once the test for the feature is complete and passes 100% of the time, I save it in a suite of other tests for the database. Before moving on to another test or a deployment, I run all the tests as a suite to make sure nothing is broken. Tests can have dependencies on other tests, and the results are recorded and displayed in a browser. Nothing new here, I am sure. Our shop is aiming toward standardizing on MSSQLServer and I want to use the same procedure for developing our databases. Does anyone know of tools that allow or encourage this kind of development? I believe the Team System does, but we do not own that at this point, and probably will not for some time. I am not opposed to scripting, but would welcome a more graphical environment. Any suggestions?

  • SQL Server: Output an XML field as tabular data using a stored procedure

    - by Pawan
    I am using a table with an XML data field to store the audit trails of all other tables in the database. That means the same XML field has various XML information. For example my table has two records with XML data like this: 1st record: <client> <name>xyz</name> <ssn>432-54-4231</ssn> </client> 2nd record: <emp> <name>abc</name> <sal>5000</sal> </emp> These are the two sample formats and just two records. The table actually has many more XML formats in the same field and many records in each format. Now my problem is that upon query I need these XML formats to be converted into tabular result sets. What are the options for me? It would be a regular task to query this table and generate reports from it. I want to create a stored procedure to which I can pass that I need to query "<emp>" or "<client>", then my stored procedure should return tabular data.

  • SQL Server insert performance

    - by Jose
    I have an insert query that gets generated like this INSERT INTO InvoiceDetail (LegacyId,InvoiceId,DetailTypeId,Fee,FeeTax,Investigatorid,SalespersonId,CreateDate,CreatedById,IsChargeBack,Expense,RepoAgentId,PayeeName,ExpensePaymentId,AdjustDetailId) VALUES(1,1,2,1500.0000,0.0000,163,1002,'11/30/2001 12:00:00 AM',1116,0,550.0000,850,NULL,@ExpensePay1,NULL); DECLARE @InvDetail1 INT; SET @InvDetail1 = (SELECT @@IDENTITY); This query is generated for only 110K rows. It takes 30 minutes for all of these query's to execute I checked the query plan and the largest % nodes are A Clustered Index Insert at 57% query cost which has a long xml that I don't want to post. A Table Spool which is 38% query cost <RelOp AvgRowSize="35" EstimateCPU="5.01038E-05" EstimateIO="0" EstimateRebinds="0" EstimateRewinds="0" EstimateRows="1" LogicalOp="Eager Spool" NodeId="80" Parallel="false" PhysicalOp="Table Spool" EstimatedTotalSubtreeCost="0.0466109"> <OutputList> <ColumnReference Database="[SkipPro]" Schema="[dbo]" Table="[InvoiceDetail]" Column="InvoiceId" /> <ColumnReference Database="[SkipPro]" Schema="[dbo]" Table="[InvoiceDetail]" Column="InvestigatorId" /> <ColumnReference Column="Expr1054" /> <ColumnReference Column="Expr1055" /> </OutputList> <Spool PrimaryNodeId="3" /> </RelOp> So my question is what is there that I can do to improve the speed of this thing? I already run ALTER TABLE TABLENAME NOCHECK CONSTRAINTS ALL Before the queries and then ALTER TABLE TABLENAME NOCHECK CONSTRAINTS ALL after the queries. And that didn't shave off hardly anything off of the time. Know I am running these queries in a .NET application that uses a SqlCommand object to send the query. I then tried to output the sql commands to a file and then execute it using sqlcmd, but I wasn't getting any updates on how it was doing, so I gave up on that. Any ideas or hints or help?

  • SQL Server: collect values in an aggregation temporarily and reuse in the same query

    - by Erwin Brandstetter
    How do I accumulate values in t-SQL? AFAIK there is no ARRAY type. I want to reuse the values like demonstrated in this PostgreSQL example using array_agg(). SELECT a[1] || a[i] AS foo ,a[2] || a[5] AS bar -- assuming we have >= 5 rows for simplicity FROM ( SELECT array_agg(text_col ORDER BY text_col) AS a ,count(*)::int4 AS i FROM tbl WHERE id between 10 AND 100 ) x How would I best solve this with t-SQL? Best I could come up with are two CTE and subselects: ;WITH x AS ( SELECT row_number() OVER (ORDER BY name) AS rn ,name AS a FROM #t WHERE id between 10 AND 100 ), i AS ( SELECT count(*) AS i FROM x ) SELECT (SELECT a FROM x WHERE rn = 1) + (SELECT a FROM x WHERE rn = i) AS foo ,(SELECT a FROM x WHERE rn = 2) + (SELECT a FROM x WHERE rn = 5) AS bar FROM i Test setup: CREATE TABLE #t( id INT PRIMARY KEY ,name NVARCHAR(100)) INSERT INTO #t VALUES (3 , 'John') ,(5 , 'Mary') ,(8 , 'Michael') ,(13, 'Steve') ,(21, 'Jack') ,(34, 'Pete') ,(57, 'Ami') ,(88, 'Bob') Is there a simpler way?

  • Remove another user's lock obtained with sp_getapplock on SQL Server

    - by joshperry
    We have a system that uses sp_getapplock to create an exclusive mutex any time someone opens an order in the GUI. This is used to prevent multiple people from making changes to an order simultaneously. Sometimes people will open an order and go home, leaving it open. This effectively blocks anyone from being able to make changes to the order. I then get emails, calls and end up doing a kill <spid> in enterprise manager. Obviously I've gotten sick of this and want to make a quick self-service webform. The main problem I've run into is that kill requires sysadmin privileges, which I do not want to give to the user that the our website runs as. I have tried sp_releaseapplock but this doesn't let you release another user's lock (even when calling it as a sysadmin). So, finally my question; does anyone know of an alternative method to release a lock that was obtained by another user using sp_getapplock?
