  • Parameter cannot be null error after success save

    I have the following SQL: SELECT * FROM [Database].dbo.[TagsPerItem] INNER JOIN [Database].dbo.[Tag] ON [Tag].Id = [TagsPerItem].TagId WHERE [Tag].Name IN ('home', 'car') and it returns: Id TagId ItemId ItemTable Id Name SiteId 1 1 1 Content 1 home 1 2 1 2 Content 1 home 1 3 1 3 Content 1 home 1 4 2 4 Content 2 car 1 5 2 5 Content 2 car 1 6 2 12 Content 2 car 1 instead of just two records, which these names are "home" and "car". How can I fix it? Thanks.

  • SQL syntax problem (multiple selects)

    - by user279521
    I am having problems retrieving accurate data values with my stored proc query below: CREATE PROCEDURE usp_InvoiceErrorLog @RecID int AS DECLARE @ErrorString as varchar(1000), @ErrorCode as int; Select @ErrorCode = ErrorCode from tbl_AcctRecv_WebRpt Where RecID = @RecID; IF NOT(@ErrorCode = NULL) Begin Select @ErrorString = ErrorDesc from tbl_ErrDesc Where ErrorCode = @ErrorCode End Select RecID, VendorNum, VendorName, InvNum, InvTotal, (SELECT CONVERT(VARCHAR(11), InvDate, 106) AS [DD MON YYYY]) As InvDate, TicketRequestor, ErrorCode, @ErrorString as ErrorDesc from tbl_AcctRecv_WebRpt Where RecID = @RecID The ErrorDesc column (in the final select statement at the bottom) returns a NULL value, when it should return a valid string data. Any ideas?

  • Replication - User defined table type not propogating to subscriber

    - by Aamod Thakur
    I created a User defined table type named tvp_Shipment with two columns (id and name) . generated a snapshot and the User defined table type was properly propogated to all the subscribers. I was using this tvp in a stored procedure and everything worked fine. Then I wanted to add one more column created_date to this table valued parameter.I dropped the stored procedure (from replication too) and also i dropped and recreated the User defined table type with 3 columns and then recreated the stored procedure and enabled it for publication When i generate a new snapshot, the changes in user defined table type are not propogated to the subscriber. The newly added column was not added to the subscription. the Error messages: The schema script 'usp_InsertAirSa95c0e23_218.sch' could not be propagated to the subscriber. (Source: MSSQL_REPL, Error number: MSSQL_REPL-2147201001) Get help: http://help/MSSQL_REPL-2147201001 Invalid column name 'created_date'.

  • How can I optimize retrieving lowest edit distance from a large table in SQL?

    - by Matt
    Hey, I'm having troubles optimizing this Levenshtein Distance calculation I'm doing. I need to do the following: Get the record with the minimum distance for the source string as well as a trimmed version of the source string Pick the record with the minimum distance If the min distances are equal (original vs trimmed), choose the trimmed one with the lowest distance If there are still multiple records that fall under the above two categories, pick the one with the highest frequency Here's my working version: DECLARE @Results TABLE ( ID int, [Name] nvarchar(200), Distance int, Frequency int, Trimmed bit ) INSERT INTO @Results SELECT ID, [Name], (dbo.Levenshtein(@Source, [Name])) As Distance, Frequency, 'False' As Trimmed FROM MyTable INSERT INTO @Results SELECT ID, [Name], (dbo.Levenshtein(@SourceTrimmed, [Name])) As Distance, Frequency, 'True' As Trimmed FROM MyTable SET @ResultID = (SELECT TOP 1 ID FROM @Results ORDER BY Distance, Trimmed, Frequency) SET @Result = (SELECT TOP 1 [Name] FROM @Results ORDER BY Distance, Trimmed, Frequency) SET @ResultDist = (SELECT TOP 1 Distance FROM @Results ORDER BY Distance, Trimmed, Frequency) SET @ResultTrimmed = (SELECT TOP 1 Trimmed FROM @Results ORDER BY Distance, Trimmed, Frequency) I believe what I need to do here is to.. Not dumb the results to a temporary table Do only 1 select from `MyTable` Setting the results right in the select from the initial select statement. (Since select will set variables and you can set multiple variables in one select statement) I know there has to be a good implementation to this but I can't figure it out... this is as far as I got: SELECT top 1 @ResultID = ID, @Result = [Name], (dbo.Levenshtein(@Source, [Name])) As distOrig, (dbo.Levenshtein(@SourceTrimmed, [Name])) As distTrimmed, Frequency FROM MyTable WHERE /* ... yeah I'm lost */ ORDER BY distOrig, distTrimmed, Frequency Any ideas?

  • Delete a Row from a DataGridView given its index

    - by Ruben Trancoso
    My DataGridView is a single line selection and theres a rowEnter Event where I get the line index every time the selected line changes. private void rowEnter(object sender, DataGridViewCellEventArgs e) { currentRowIndex = e.RowIndex; } when I press a delete button I use the same index to delete the row myDataSet.Avaliado.Rows[currentRowIndex].Delete(); avaliadoTableAdapter.Update(myDataSet.Avaliado); it works fine if no column in the DataGridView is sorted, otherwise a get an error. What should be the way to know the row index in the dataset that corresponds to the rowindex from the DataGridView?

  • Using application roles with DataReader

    - by Shahar
    I have an application that should use an application role from the database. I'm trying to make this work with queries that are actually run using Subsonic (2). To do this, I created my own DataProvider, which inherits from Subsonic's SqlDataProvider. It overrides the CreateConnection function, and calls sp_appsetrole to set the application role after the connection is created. This part works fine, and I'm able to get data using the application role. The problem comes when I try to unset the application role. I couldn't find any place in the code where my provider is called after the query is done, so I tried to add my own, by changing SubSonic code. The problem is that Subsonic uses a data reader. It loads data from the data reader, and then closes it. If I unset the application role before the data reader is closed, I get an error saying: There is already an open DataReader associated with this Command which must be closed first. If I unset the application role after the data reader is closed, I get an error saying ExecuteNonQuery requires an open and available Connection. The connection's current state is closed. I can't seem to find a way to close the data reader without closing the connection.

  • Copying a subset of data to an empty database with the same schema

    - by user193655
    I would like to export part of a database full of data to an empty database. Both databases has the same schema. I want to maintain referential integrity. To simplify my cases it is like this: MainTable has the following fields: 1) MainID integer PK 2) Description varchar(50) 3) ForeignKey integer FK to MainID of SecondaryTable SecondaryTable has the following fields: 4) MainID integer PK (referenced by (3)) 5) AnotherDescription varchar(50) The goal I'm trying to accomplish is "export all records from MainTable using a WHERE condition", for example all records where MainID < 100. To do it manually I shuold first export all data from SecondaryTable contained in this select: select * from SecondaryTable ST outer join PrimaryTable PT on ST.MainID=PT.MainID then export the needed records from MainTable: select * from MainTable where MainID < 100. This is manual, ok. Of course my case is much much much omre complex, I have 200+ tables, so donig it manually is painful/impossible, I have many cascading FKs. Is there a way to force the copy of main table only "enforcing referntial integrity". so that my query is something like: select * from MainTable where MainID < 100 WITH "COPYING ALL FK sources" In this cases also the field (5) will be copied. ====================================================== Is there a syntax or a tool to do this? Table per table I'd like to insert conditions (like MainID <100 is only for MainTable, but I have also other tables).

  • How to use a variable to specify filegroup in MSSQL

    - by gt
    I want to alter a table to add a constraint during upgrade on a MSSQL 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?

  • Auto Generated - CREATE Table Script in SQL 2008 throws error

    - by jack
    I scripted the tables in my dev database using SQL 2008 - generate scripts option (Datbase-right click-Tasks-Generate Scripts) and ran it on the staging database, but the script throws the below error for each table Msg 102, Level 15, State 1, Line 1 Incorrect syntax near '('. Msg 319, Level 15, State 1, Line 15 Incorrect syntax near the keyword 'with'. If this statement is a common table expression, an xmlnamespaces clause or a change tracking context clause, the previous statement must be terminated with a semicolon.

  • AM I using DO WHILE NOT and EOF in VBscript Properly

SQL_Command_String = "SELECT * FROM Seminars WHERE [SeminarID] = 5 ORDER BY DESC" Rs = SQLConnection.Execute(SQL_Command_String) DO WHILE NOT Rs.EOF file1 = "./seminars/" & seminar_type & "/" & seminar_year & "/" & Rs("Date") & "-" & Rs("Year") & "_" & Rs("Last") & ".pdf" file2 = "./seminars/" & seminar_type & "/" & seminar_year & "/" & Rs("Date") & "-" & seminar_year & "_" & Rs("Last") & "(handouts).pdf" file3 = "./seminars/" & seminar_type & "/" & seminar_year & "/" & Rs("Date") & "-" & seminar_year & "_" & Rs("Last") & "_Flyer.pdf" Rs.MoveNext loop Is the SQL_Command_String an invalid SQL Command or is my reader not being used properly when I try to build that specific file path e.g. Rs("Date")? Is there an option where I could do something like: DO WHILE RS.hasNextLine

  • Unable to add Solution to TFS 2010 due to existing (invisible)binding

    - by Refracted Paladin
    I have a smallish utility library I made that I had created in TFS Beta 2 to test out TFS. I now have TFS rc1 installed(and Beta 2 uninstalled) and am trying to add my Solution to TFS. I get an error saying that it is already bound to my old TFS, which was on a different system then this one. Strangely, when I go into Source Control and look at the bindings it says there aren't any. Also, I manually deleted the .vss and .vsc files and it still does it. Ideas? I looked through the numerous other SO topics related to this but unless I missed one none of them are dealing with my issue. Ideas?

  • Database Table Schema and Aggregate Roots

    - by bretddog
    Hi, Applicaiton is single user, 1-tier(1 pc), database SqlCE. DataService layer will be (I think) : Repository returning domain objects and quering database with LinqToSql (dbml). There are obviously a lot more columns, this is simplified view. http://img573.imageshack.us/img573/3612/ss20110115171817w.png This is my first attempt of creating a 2 tables database. I think the table schema makes sense, but I need some reassurance or critics. Because the table relations looks quite scary to be honest. I'm hoping you could; Look at the table schema and respond if there are clear signs of troubles or errors that you spot right away.. And if you have time, Look at Program Summary/Questions, and see if the table layout makes makes sense to those points. Please be brutal, I will try to defend :) Program summary: a) A set of categories, each having a set of strategies (1:m) b) Each day a number of items will be produced. And each strategy MAY reference it. (So there can be 50 items, and a strategy may reference 23 of them) c) An item can be referenced by more than one strategy. So I think it's an m:m relation. d) Status values will be logged at fixed time-fractions through the day, for: - .... each Strategy.....each StrategyItem....each item e) An action on an item may be executed by a strategy that reference it. - This is logged as ItemAction (Could have called it StrategyItemAction) User Requsts b) - e) described the main activity mode of the program. To work with only today's DayLog , for each category. 2nd priority activity is retrieval of history, which typically will be From all categories, from day x to day y; Get all StrategyDailyLog. Questions First, does the overall layout look sound? I'm worried to see that there are so many relationships in all directions, connecting everything. Is this normal, or does it look like trouble? StrategyItem is made to represent an m:m relationship. Is it correct as I noted 1:m / 1:1 (marked red) ? StrategyItemTimeLog and ItemTimeLog; Logs values that both need to be retrieved together, when retreiving a StrategyItem. Reason I separated is that the first one is strategy-specific, and several strategies can reference same item. So I thought not to duplicate those values that are not dependent no strategy, but only on the item. Hence I also dragged out the LogTime, as it seems to be the only parameter to unite the logs. But this all looks quite disturbing with those 3 tables. Does it make sense at all? Or you have suggestion? Pink circles shows my vague attempt of Aggregate Root Paths. I've been thinking in terms of "what entity is responsible for delete". Though I'm unsure about the actual root. I think it's Category. Does it make sense related to User Requests described above?

  • Return unordered list from hierarchical sql data

    - by Milan
    I have table with pageId, parentPageId, title columns. Is there a way to return unordered nested list using asp.net, cte, stored procedure, UDF... anything? Table looks like this: PageID ParentId Title 1 null Home 2 null Products 3 null Services 4 2 Category 1 5 2 Category 2 6 5 Subcategory 1 7 5 SubCategory 2 8 6 Third Level Category 1 ... Result should look like this: Home Products Category 1 SubCategory 1 Third Level Category 1 SubCategory 2 Category 2 Services Ideally, list should contain <a> tags as well, but I hope I can add it myself if I find a way to create <ul> list. EDIT 1: I thought that already there is a solution for this, but it seems that there isn't. I wanted to keep it simple as possible and to escape using ASP.NET menu at any cost, because it uses tables by default. Then I have to use CSS Adapters etc. Even if I decide to go down the "ASP.NET menu" route I was able to find only this approach: http://aspalliance.com/822 which uses DataAdapter and DataSet :( Any more modern or efficient way?

  • MSSQL in ASP.NET application getting unstable after a certain period

    - by Barslett
    Hello, I have an ASP.NET 2.0 application that I made to keep track of disruption reports about our public transport system. The architecture is pretty straight-forward; an MSSQL Express 2008 database, ADO.NET and a DataSet/DAL with a few methods to access the database. There is a set of .aspx pages for the UI in use by our dispatchers and on our public website, as well as a set of SOAP and REST webservices and an RSS feed. Everything worked just fine for more than a year, until two weeks ago. Now and then, it seems as the database enters an unstable mode, and the application starts responding something right, something wrong. The typical error is that apparently, an empty DataTable is returned to the public disruption overview or to the RSS generator. Thus, the user gets e.g. an empty GridView, but no exception is thrown AFAIK, and nothing is written to the Windows Application log. After a restart of the MSSQL Express service, the situation is back to normal. It has to be said that the situation first time appeared a few days after I made a new minor upgrade of the application. The RSS generator was slightly rewritten, and I added a WCF REST service. But the DAL and the database schema were untouched... Any hints of how we could keep the database stable? It is a bit annoying not to have a clue ;-)

  • TransactionScope question - how can I keep the DTC from getting involved in this?

    - by larryq
    (I know the circumstances surrounding the DTC and promoting a transaction can be a bit mysterious to those of us not in the know, but let me show you how my company is doing things, and if you can tell me why the DTC is getting involved, and if possible, what I can do to avoid it, I'd be grateful.) I have code running on an ASP.Net webserver. We have one database, SQL 2008. Our data access code looks something like this-- We have a data access layer that uses a wrapper object for SQLConnections and SQLCommands. Typical use looks like this: void method1() { objDataObject = new DataAccessLayer(); objDataObject.Connection = SomeConnectionMethod(); SqlCommand objCommand = DataAccessUtils.CreateCommand(SomeStoredProc); //create some SqlParameters, add them to the objCommand, etc.... objDataObject.BeginTransaction(IsolationLevel.ReadCommitted); objDataObject.ExecuteNonQuery(objCommand); objDataObject.CommitTransaction(); objDataObject.CloseConnection(); } So indeed, a very thin wrapper around SqlClient, SqlConnection etc. I want to run several stored procs in a transaction, and the wrapper class doesn't allow me access to the SqlTransaction so I can't pass it from one component to the next. This led me to use a TransactionScope: using (TransactionScope tx1 = new TransactionScope(TransactionScope.RequiresNew)) { method1(); method2(); method3(); tx1.Complete(); } When I do this, the DTC gets involved, and unfortunately our webservers don't have "allow remote clients" enabled in the MSDTC settings-- getting IT to allow that will be a fight. I'd love to avoid DTC becoming involved but can I do it? Can I leave out the transactional calls in methods1-3() and just let the TransactionScope figure it all out?

  • Varchar columns: Nullable or not.

    - by NYSystemsAnalyst
    The database development standards in our organization state the varchar fields should not allow null values. They should have a default value of an empty string (""). I know this makes querying and concatenation easier, but today, one of my coworkers questioned me about why that standard only existed for varchar types an not other datatypes (int, datetime, etc). I would like to know if others consider this to be a valid, defensible standard, or if varchar should be treated the same as fields of other data types? I believe this standard is valid for the following reason: I believe that an empty string and null values, though technically different, are conceptually the same. An empty, zero length string is a string that does not exist. It has no value. However, a numeric value of 0 is not the same as NULL. For example, if a field called OutstandingBalance has a value of 0, it means there are $0.00 remaining. However, if the same field is NULL, that means the value is unknown. On the other hand, a field called CustomerName with a value of "" is basically the same as a value of NULL because both represent the non-existence of the name. I read somewhere that an analogy for an empty string vs. NULL is that of a blank CD vs. no CD. However, I believe this to be a false analogy because a blank CD still phyically exists and still has physical data space that does not have any meaningful data written to it. Basically, I believe a blank CD is the equivalent of a string of blank spaces (" "), not an empty string. Therefore, I believe a string of blank spaces to be an actual value separate from NULL, but an empty string to be the absense of value conceptually equivalent to NULL. Please let me know if my beliefs regarding variable length strings are valid, or please enlighten me if they are not. I have read several blogs / arguments regarding this subject, but still do not see a true conceptual difference between NULLs and empty strings.
