I have a web page that has been in production for over a year. On occasion the web app users report sporadic errors which last a few minutes then go away. The page loads up a generic DataSet, and then that DataSet is assigned to a datagrid on the page. The error is that a column that is expected to be in the dataset is not found. I know this column must exist in the database because its a required field. After we reset IIS, then all returns to normal and the errors go away. Below is the stack trace.
Exception: System.IndexOutOfRangeException Message: Cannot find column LastName. Source: System.Data at System.Data.DataTable.ParseSortString(String sortString) at System.Data.DataView.UpdateIndex(Boolean force) at System.Data.DataView.SetIndex(String newSort, DataViewRowState newRowStates, DataFilter newRowFilter) at System.Data.DataView..ctor(DataTable table, String RowFilter, String Sort, DataViewRowState RowState) at MySystem.Web.GuestSearch.ShowResults(DataSet ds, Int32 currentPageIndex) at MySystem.Web.GuestSearch.LoadResults(Int32 currentPageIndex) at MySystem.GuestSearch.btnSearch_Click(Object sender, EventArgs e) at System.Web.UI.WebControls.Button.OnClick(EventArgs e) at System.Web.UI.WebControls.Button.System.Web.UI.IPostBackEventHandler.RaisePostBackEvent(String eventArgument) at System.Web.UI.Page.RaisePostBackEvent(IPostBackEventHandler sourceControl, String eventArgument) at System.Web.UI.Page.RaisePostBackEvent(NameValueCollection postData) at System.Web.UI.Page.ProcessRequestMain()
Our DBA can find no problems on the database side and our web servers don't log any system event problems either. I do not understand why resetting IIS helps the issue. I need to find the real cause of the problems rather than just resetting IIS all the time. Any ideas?
I'm using a SqlDataSource with a GridView to look at the contents of a table. I'd like to display the number of rows returned by the query in a label above the grid. How do I get a hold of this value? I can't find where it's exposed through the DataSource or the Grid. I can get the number of rows in the currently displayed page, but that's not the value I'm after.
I am working on a company sign out sheet for our Intranet. The application accesses a sql database. I tried using a datareader as well as a dataset to access a small piece of information regarding the group that each employee belongs to in the company. My last attempt was to assign the value to the text property of a text box and evaluate the text from the text box with the Select Case but that did not work either.The application is supposed to generate an email to our receptionist as well as to the group technical assistant responsible for each group according to the value that is passed into the Select Case statement. With the datareader as well as the dataset and even now with creating a text box and accessing the text property, I was able to assign the group value to a variable (I can see the value in the subject of the email), but when the variable is supposed to be evaluated by the select case statement it skips right through all of the cases to case else and uses only the receptionist's address in the email as if it doesn't even see the value of the variable. I have searched for a possible answer to the problem I am but so far have had no luck. Any ideas? I included the part of the code that I am having trouble with: '********************************************************************************************' New DataSet is created to determine the group the employee belongs to so that the appropriate' group technical assistant is emailed when employee signs out'******************************************************************************************** ' declare variablesDim sqlGroup As String ' string variable to store sql statement for datasetDim BLGroup As String ' string variable to store the bl group of the employeeDim emailAddress As String ' string variable to store resulting email address Dim groupDS As DataSet ' dataset variableDim groupAdapter As SqlDataAdapter ' sql data adapter variable' sql statement to access group value from the databasesqlGroup = "SELECT BLGroup FROM BLGroupsView WHERE (RTRIM(fname) + ' ' + LTRIM(lname)='" & employee & "')" ' repopen the connection (leftover from working with the datareader)Connection.Open()' create new SqlDataAdapter applying sql statement and connectiongroupAdapter = New SqlDataAdapter(sqlGroup, Connection)' create new dataset groupDS = New DataSet()' populate the datasetgroupAdapter.Fill(groupDS, "BLGroupsView") ' get the value stored in the BLGroup column (only one row is returned at a time) BLGroup = groupDS!BLGroup' Create GroupTextBox TextBox control.Dim GroupTextBox As New TextBox()' Set options for the UserTextBox TextBox control.GroupTextBox.ID = "GroupTextBox"GroupTextBox.Visible = "False"GroupTextBox.Text = BLGroup' just trying anything with this next line, even when i didn't set this the select case statement did not seem to see the value returned by the variableGroupTextBox.runat = "server" ' use a select case statement to evaluate the value of the group (didn't work when I passed in the BLGroup variable eitherSelect Case GroupTextBox.TextCase "bh"emailAddress = "receptionist@myaddress.com; bhassistant@myaddress.com"Case "env"emailAddress = "receptionist@myaddress.com; envassistant@myaddress.com"Case "sw"emailAddress = "receptionist@myaddress.com; swassistant@myaddress.com"Case "fac"emailAddress = "receptionist@myaddress.com; facassistant@myaddress.com"Case "www"emailAddress = "receptionist@myaddress.com; wwwassistant@myaddress.com"Case ElseemailAddress = "receptionist@myaddress.com"End Select '*************************************************************************************************' set new message objectDim myMessage As System.Web.Mail.MailMessage = New System.Web.Mail.MailMessage()'**********************************************************' set message properties'********************************************************** myMessage.From = "me@myaddress.com"myMessage.To = emailAddressmyMessage.Subject = employee & " Signing Out at " & TimeOut.Text & " " & BLGroupmyMessage.Body = employee & " Signing Out at " & TimeOut.Text & " for " & Destination.Text & " will potentially return at " & EstTimeIn.Text'***********************************************************' set smtp server namesmtpMail.SmtpServer = "mailserver1"' send email using smtpsmtpMail.Send(myMessage) It sends the message and returns the BLGroup value everytime but only sends to the receptionist.

I have an existing call to a webservice that updates an MDB with data from a dataset. I was now moving to a process using SQL Compact Edition sdf instead of an mdb.
I belive I have to DROP/Truncate the table in the SDF file, then create a new table then somehow insert the results of the retrieved dataset into the new table. DOes anybody have any pointers to help me out?
Here is my old way of doing it, using access.
Thanks.

In one of my projects, i have been using the SSRS web service to render a report as pdf and then manually emailing it out.
I need to know whether the data set for the report returned any data or not (so that i can avoid emailing the report with a blank report body).
Ofcource this can be done by executing the same query (same as the query for the report) from C# code and checking the count of the resultset, before calling the SSRS Render method. But it might not be an efficient method.
Was wondering the the SSRS Web Service provides an property or method that can let me figure out whether the resultset was empty or not (after the report execution).
I have the following sql:SELECT courseModuleCode FROM courses WHERE courseCode like '%' + @prefixText + '%'UNION SELECT courseName FROM courses WHERE courseName like '%' + @prefixText + '%' UNIONSELECT TeacherName FROM courses WHERE TeacherName like '%' + @prefixText + '%' it returns one column, i want to name tha column as "words"how do i do it?thanks
in the 2nd case, column1 contains all the same values, so yes
is there anyway i can check this? i would be doing this in a trigger.. say when a new row is inserted, the value of column1 is inserted, but col 2 is null.. so when they try to fill in the value for col2 of that row, the trigger checks to see if the value they put for col 2 is already in the table.. if it isn't, then everything is ok. but if it is already in teh table, then it checks col1 to see if all the values of col1 are the same
Is there a way to hide a column if there is no data for that column? Suppose that I have a SP (lets call it wrapper) which will call multiple SP's. But for any one run, there'll be only one SP which is called. But the columns returned by these SP's is obviously different. So, in order to accomodate the output, can I create a table, add all the possible columns to it, and set the properties of the individual columns such that they will be hidden if there is no data in them? Example, SP 1 returns - ServerName, Location, OS ; SP 2 returns ServerName and location only. Now if the wrapper SP calls only the second SP (SP 2) can I configure in such a way that the third column (OS) is not displayed at all? (In normal cases, it would appear but without any data in it)...
I¡¦ve got a table with the following as well as other info:
User ID DirectoryTypeID (int) Region ID (int)
I need to run a query where I could get the region ID, then, in the second column, I¡¦d get all distinct directory types within that region. For example, if I run the query:
In a query in Management Studio, I want to output data to a text file (via Results in text button) without column names and hyphens or dashes, I have searched all SET commands with bad luck because SET FMTONLY OFF do exactly the opposite.
I know this could be a silly question because I have received suggestions in other ways to do that, but I am intrigued If there is a way to prevent column name from being displayed/returned from a query.

I am building reports against our TFS development db. One of the reports tracks days spent (Dwell Time) in various status categories (eg: New, Assigned, In Development, Hold, etc) for a given "ticket". For a fixed list of values from {Work Item].System_State, I can send the results (days in Assigned) to the column named (Assigned) for each status for each event in the [Work Item History], and then sum them for each ticket as: Ticket ID New Assigned InDev etc 1230001 2 0 0 ... 1230001 0 1 2 ....
SUM 2 1 2 .... However, I have many different Projects, each of which use their own Status names. I don't want to duplicate the same basic report, if I can avoid it.
How can I name and generate this data for the unique Status list for each Project?
Simplest analog is: name = First(Fields!Status.Value, "TFSdb") and allows value for a column name (category) as: =IIF(Fields!Status.Value = First(Fields!Status.Value, "TFSdb"), Fields!Days.Value, 0) However this fails beause: 1. It only delivers the FIRST status value, and, 2. I cannot SUM an expression which is itself an aggregate (using First).
I have a question regarding the values returned in the SEARCHABLE column of the system stored procedure sp_datatype_info. What do ALL of the values mean? The SQL Server BOL only provides meanings for the values 0 and 1, but I am also seeing values 2 and 3. What are the meanings of these values?
I can preview the SQL command in the OLE DB Source Editor and bring back all columns and results just fine but when I click on the Columns I get
TITLE: Microsoft Visual Studio ------------------------------ The component reported the following warnings: Error at Data Flow Task [OLE DB Source [1]]: No column information was returned by the SQL command.
The columns are there in the preview - why can't SSIS get the column information?
Hi, I was wondering if any SQL Server gurus out there could help me...I have a table which contains text resources for my application. The text resources are multi-lingual so I've read that if I add a html language indicator meta tag e.g.<META NAME="MS.LOCALE" CONTENT="ES">and store the text in a varbinary column with a supporting Document Type column containing ".html" of varchar(5) then the full text index service should be intelligent about the language word breakers it applies when indexing the text. (I hope this is correct technique for best multi-lingual support in a single table?)However, when I come to query this data the results always return 0 rows (no errors are encountered). e.g.DECLARE @SearchWord nvarchar(256)SET @SearchWord = 'search' -- Yes, this word is definitely present in my resources.SELECT * FROM Resource WHERE CONTAINS(Document, @SearchWord)I'm a little puzzled as Full Text search is working fine on another table that employs an nvarchar column.Any pointers / suggestions would be greatly appreciated. Cheers,Gavin.

I have had to add a new column to a mobile 5 database in VS2005. I obviously have added it in the wrong way. I have two applications that use the same db. The .net application accesses the table with the new column fine., this is where I added it first. When I try to add the column to the Compact framework (Pocket Pc) app I get this error when I try to run the application. In both applications the Server explorer shows the new column. The column name is not valid. [ Node name (if any) = ,Column name = GUID ] As long as I remove the GUID column from the tableadapter.fill sql the program runs the same as before.( even though the sql executes in the query designer with the GUID column in the sql statement.) How do I add the column so that the Dataset.designer.cs gets updated and can load the new column?
Hi thereI have the following two tablesmainprofile (profile varchar(20), description)accprofile (profile varchar(20), acct_type int)Sample data could bemainprofile----------------prof1 | profile oneprof2 | profile twoprof3 | profile threeaccprofile--------------prof1 | 0prof1 | 1prof1 | 2prof2 | 0Now doing a join between these two tables would return multiple rows,but I would like to know whether it would be possible to returnacct_type horizontally in a column of the result set, e.g.prof1 | profile one | [0,1,2]prof2 | profile two | [0]I could probably manage this with cursors, but it would be veryresource intensive. Is there a better way?Regards,Louis
I have a strange problem. I have some code that executes a sql query. If I run the query in SQL server query analyzer, I get a set of data returned for me as expected. This is the query listed on lines 3 and 4. I just manually type it into query analyzer. Yet when I run the same query in my code, the result set is slightly different because it is missing some data. I am confused as to what is going on here. Basically to examine the sql result set returned, I write it out to an XML file. (See line 16). Why the data returned is different, I have no idea. Also writing it out to an XML file is the only way I can look at the data. Otherwise looking at it in the debugger is impossible, with the hundreds of tree nodes returned. If someone is able to help me figure this out, I would appreciate it. 1. public DataSet GetMarketList(string region, string marketRegion)2. {3. string sql = @"SELECT a.RealEstMarket FROM MarketMap a, RegionMap b " + 4."WHERE a.RegionCode = b.RegionCode"; 5. DataSet dsMarketList = new DataSet();6. SqlConnection sqlConn = new SqlConnection(intranetConnStr); 7. SqlCommand cmd = new SqlCommand(sql,sqlConn);8. sqlConn.Open();9. SqlDataAdapter adapter = new SqlDataAdapter(cmd); 10. try11. {12. adapter.Fill(dsMarketList); 13. String bling = adapter.SelectCommand.CommandText;//BRG 14. dsMarketList.DataSetName="RegionMarket"; 15. dsMarketList.Tables[0].TableName = "MarketList"; 16. dsMarketList.WriteXml(Server.MapPath ("myXMLFile.xml" )); // The data written to 17. myXMLFile.xml is not the same data that is returned when I run the query on line 3&4 18. // from the SQL query 19. } 20. catch(Exception e) 21. { 22. // Handle the exception (Code not shown)
Hi all, I'm trying to update various rows in my DB with a new value once an action occurs. I am using the following code which does not throw any exceptions, but also does not change the values. Can someone steer me in the right direction? public static void ChangeRefCode() { SqlConnection dbConn = new SqlConnection(ConnectDB.getConnectString()); SqlDataAdapter dataAdapt = new SqlDataAdapter("Select * from Posting",dbConn);
So I setup a flat file csv connection with comma as column delim, CR/LF as row delim, etc. Everything works as planned and the package executes.
Now lets say the file comes in wrong and has two columns instead of three. It looks like this. R1C1, R1C2 R2C1, R2C2 R3C1, R3C2
The SSIS file manager reads the file as two rows vs failing. So it reads the above as this... R1C1, R1C2, {LF/CR}R2C1 R2C2, {LF/CR}R3C1, R3C2
This is obviously not right. You get similar issues if they send an extra column where data is just added to the last column. How do you get SSIS to fail or error out if the column count is wrong?
My report's data source is a stored procedure which takes 4 parameters. If I execute the sp from the data tab it returns the correct data and columns; but if I right click the Report Datasets from the Datasets view and click on refresh I'm always missing one column. Is this related to the way the sp was written? Anybody had same expericence before? Thanks!

I have a form that loads a dataset. This dataset is composed from SQL statements using alias and unions. Basically it takes uses data from 3 tables. This dataset also has a alias column called ClientName that consists of either people's name or business name.In addition, the form also consist of a search field that allows user to enter the 'ClientName' to be searched (i.e. to search the alias column). So, my question is how can the alias column be searched (user can also enter % in the search field)Function QueryByService(ByVal searchClientNameText As String) As System.Data.DataSet If InStr(Trim(searchClientNameText), "%")>0 Then searchStatement = "WHERE ClientName LIKE '" & searchClientNameText & "'"Else searchStatement = "WHERE ClientName = @searchClientNameText"End If Dim queryString As String = "SELECT RTrim([People].[Given_Name])"& _"+ ' ' + RTrim([People].[Family_Name]) AS ClientName, [Event].[NumEvents],"& _"[Event].[Event_Ref]"& _"FROM [Event] INNER JOIN [People] ON [Event].[APP_Person_ID] = [People].[APP_Person_ID]"& _searchStatement + " "& _"UNION SELECT [Bus].[Organisation_Name],"& _"[Event].[NumEvents], [Event].[Event_Ref]"& _"FROM [Bus] INNER JOIN [Event] ON [Bus].[APP_Organisation_ID] = [Event].[APP_Organisation_ID] "& _searchStatement ..........End Function
I am trying to eliminate the extra space in columns that have been returned from a DB query...the tables have character lengths of 40, I would like to return just the necessary characters.
I'm bothered by an issue of updating a column in input dataset from a update query. It looks like SSIS has a very poor function on this.
Example, I have an input dataset of name, salary, dept_no, and I have another table called departments which has fields of dept_no, Dept_name, basic_salary
now I want to update salary column in input dataset with basic_salary if it's salary is smaller than the basic_salary.
update #tmp set salary = basic_salary where #tmp.salary <departments.basic_salary and #tmp.dept_no = departments.dept_no
how could I impletement this in SSIS package?
I tried with lookup, modify scripts by enabling memory restriction. It doesn't say any error when I save the package, but I never get pass debug.
I am mapping an entity from SQL 2005 to another entity in another system on SQL 2000. Since the destination system has its own ID generator, I want to keep the generated ID for each row of my table in a column of my table in SQL 2005. The new column is in the dataset now , but I don't know how to update my table to have that column values (The OleDbDestination just insert new items.)
