MessageSource Expression Causes False Max Width Exception - Why?
Aug 31, 2007
Greetings,
I have a package that uses a complex expression for the MessageSource property in a Send Mail task. I receive the email that is composed based on the expression and it is formatted properly. However, the application also throws an exception complaining that the width of the expression may be too wide.
This is the error message (with the long expression represented by "...") from the exception:
Error Code: -2147192616
Error Description: The result string for expression " ... " may be truncated if it exceeds the maximum length of 4000 characters. The expression could have a result value that exceeds the maximum size of a DT_WSTR.
I tried wrapping the expression in SUBSTRING(expression, 1, 4000) to guarantee that the resolved expression could not cause an exception but that didn't help. Numbers lower than 4000 also do not solve the problem.
I am using Naive Bayes, Decision Trees, and Neural Net (SSAS 2005) to predict which of two states each record belongs to.
How can I enforce a different penalty for a false positive versus a false negative ? (I am assuming that in some sense the mining algorithms can then minimize the total penalty).
I am using sql reporting service 2005 with .NET 2.0. I have created a custom dll file for report and put this dll in appropriate folder. Report is running fine in designer project. but when I am trying to view this report after uploading to report manager it give me an error like
Failed to load expression host assembly. Details: The type initializer for 'CableReporting.Utilities' threw an exception. (rsErrorLoadingExprHostAssembly)Is there any solution for that?
I have a subreport on my main report, and the subreport contains a matrix. When I run the report, the subreport seems to expand beyond the width of the main report. The matrix itself does not expand beyond the width of the body of the main report, but for some reason it seems that the subreport does. The subreport does not contain any headers that might be messing up the width. If I cut and paste the matrix from the subreport directly onto the main report, and remove the subreport, it prints fine. But as soon as I include the subreport on the main report it prints with blank pages because the subreport expands beyond the width of the body of the main report. I have checked the width and margins on the subreport and compared to the width of the main report and all looks good. Can anyone help?
I'm trying to read in a flat file (which, admittedly, has one very wide column), and it keeps breaking because of truncation when it tries to read in the file.
I've a report projects where each report has a number of columns and the spec is to have all the columns print-out on the same page. Is there a setting that will auto-scale these columns to fit to the page or will I have to edit the font size and widths manually on each report to fit to the page?
Wondering if it is by design that when I select messagesource to be variable it only shows user variables or if there is some setting I'm missing to expose the system variables?
This email task is on the eventhandler tab. Thanks
I am trying to create a program that transfers tables to flat files. At this point in time, I have suceeded in created one that creates delimited files.
However, I am now trying to create fixed-width files as you can do with the SSIS designer, but programatically.
Is there a way to programatically determine the width of a column from the source table? I can not seem to find any kind of function or member that stores this information or allows me to retrieve it.
I know what I need to change in order to set a width for a column, but I just don't know how to find the width without just asking the user to provide one.
Greetings everyone, I am attempting to build my first application using Microsofts Sql databases. It is a Windows Mobile application so I am using Sql Server Compact 3.5 with Visual Studio 2008 Beta 2. When I try and insert a new row into one of my tables, the app throws the error message shown in the title of this topic. '((System.Exception)($exception)).Message' threw an exception of type 'System.NotSupportedException'
My table has 4 columns (i have since changed my FavoriteAccount datatype from bit to Integer) http://i85.photobucket.com/albums/k71/Scionwest/table.jpg
Account type will either be "Checking" or "Savings" when a new row is added, the user will select what they want from a combo box.
Next is a snap shot of my startup form. http://i85.photobucket.com/albums/k71/Scionwest/form.jpg
Where it says "Favorite Account: None" in the top panel, I am using a link label. When a user clicks "None" it will go to a account creation wizard, and set the first account as it's primary/favorite. As more accounts are added the user can select which will be his/her primary/favorite. For now I am just creating a sample account when the label is clicked in an attempt to get something working. Below is the code used.
account.FavoriteAccount = 1;//datatype is an integer, I have changed it since I took the screenshot.
financesDataSet.BankAccount.Rows.Add(account); //The next three lines where added while I was trying to get this to work. //I don't know if I really need them or not, I receive the error regardless if these are here or not.
catch (global:ystem.InvalidCastException e) { //Stops at the following line, this error was caused by 'if (this.financesDataSet.BankAccount[num].FavoriteAccount == 1)'
throw new global:ystem.Data.StrongTypingException("The value for column 'FavoriteAccount' in table 'BankAccount' is DBNull.", e);
I have no idea what I am doing wrong, all of the code I used I retreived from Microsofts help documentation included with VS2008. I have tried used my TableAdapter.Insert() method and it still failed when it got to
if (this.financesDataSet.BankAccount[num].FavoriteAccount == 1)
in my refreshDatabase() method it still failed.
When I look, the data has been added into the database, it's just when I try to retreive it now, it bails on me. Am I retreiving the information wrong?
There is a table t1 with two fields, such as, ID NAME １ Ｔｏｋｙｏ 2 Xian 3 America
For there are full-width and half-width strings in the values of the two fields, I can not select and get the right records. So I want to transform the two fields ID and NAME, I fail to find the function in the SQL Server 2005. Please give me some advice.
When running the package in VisualStudio it runs properly, but if I let this package run as part of an SQL-Server Agent job, I got the message "The script threw an exception: Exception of type 'System.OutOfMemoryException' was thrown." on my log and the package ends up with an error.
Both times it is exactly the same package on the same server, so I don't know how the debug or even if there is anything I need to debug?

I have created 1 report with 2 datasets. This report is attached to the 1st dataset.For example,1st one is "Smallappliances", 2nd is "Largeappliances".
I created a tablix and, the 1st column extracts Total sales per Sales person between 2 dates from 1st dataset (Small appliances). I used running values expression and it works fine.
Now, I would like to add another column that extracts Total sales per sales person between 2 dates from 2nd dataset (Large appliances). I am aware that I need to use Lookup expression and it is giving me the single sales value rather than the total sales values. So, I wanted to use RunningValue expression within lookup table to get total sales for large appliances.
This is the lookup expression that I added for the 2nd column.
I get this error when I preview the report.An error occurred during local report processing.The definition of the report is invalid.An unexpected error occurred in report processing.
I have a table by the name of Info, in this table I have columns with the following names FirstName, LastName, PhoneNumber, CustomerID. In the columns I have the following data FirstName = Beth LastName = Riddle PhoneNumber = 864-555-1212 CustomerID = 4 The problem is with the following statement in the .vb file. The statement keeps produceing a false value, when the desired value is Beth. TextBox1.Text = SqlDataSource1.SelectCommand = "SELECT 'FirstName' From 'Info' Where(PhoneNumber = '864-555-1212')" Please help Thanks for the information
I have a stored procedure that has a boolean (bit) field passed to it (@emailcontract). If a user checks the check box on the webform I would like my where to return only the records where the email_contract column is true. If they don't check the check box I would like it to return records where email_contracts is true or false. What would my where cluse look lile for this?
when ever i drop a ole db source or destination control on data flow, upon clicking to edit it complains about -- defaultcodepage is set to false. When i check in the properties and set it to true; i get no error. What is it all about?
Hi, I need to check the existence of a row in a table. So i am using an if condition like set ANSI_NULLS ON set QUOTED_IDENTIFIER ON go
ALTER PROCEDURE [dbo].[CheckNOAStages] @NOAID int, @StageCode nchar(20) AS BEGIN
SET NOCOUNT ON; Declare @Count int Select @Count =Count(NOAId) from NOAStages where NOAID=@NOAID and StageCode=@StageCode if (@Count>0) Begin return 1 end else begin return 0 end
END
The stored proc is executing but on the Data Access Layer I have this Boolean exists = Convert.ToBoolean (Execute.ExecuteReader(spCollection, dbSQL));
Some how I am always getting false . How can I fix this? Thanks
I am exporting an SQL Server table to a comma delimited text file. The values of Columns defined as Bit are exported as "True" or "False", but I would like that in the file appear 1 or 0 instead (with no surrounding double quotes). How can I acomplish that?
I tried using a Transformation and convert to single byte unsigned integer, but True values are exported as "255" and False values as "0". Why?
Hi there, I've tried googling this (and looking at the many questions on the forum :) but I've not managed to find a decent tutorial / guide that describes a method for using checkboxs to insert true/false flags in a MS SQL db. The db field i'm setting has type set to "bit", is this correct? And secondly (its been a long day!) I just cant figure out the code to assign the bit 1 or 0 / true or false. This is what I've got so far but it's not working........Function InsertProduct(ByVal prod_code As String, ByVal prod_name As String, ByVal prod_desc As String, ByVal prod_size As String, ByVal prod_price As String, ByVal prod_category As String, ByVal aspnet As Boolean) As Integer Dim connectionString As String = "server='server'; user id='sa'; password='msde'; Database='dbLD'" Dim sqlConnection As System.Data.SqlClient.SqlConnection = New System.Data.SqlClient.SqlConnection(connectionString) Dim queryString As String = "INSERT INTO [tbl_LdAllProduct] ([prod_code], [prod_name], [prod_desc], [prod_size], [prod_price], [prod_category],[aspnet]) VALUES (@prod_code, @prod_name, @prod_desc, @prod_size, @prod_price, @prod_category, @aspnet)" Dim sqlCommand As System.Data.SqlClient.SqlCommand = New System.Data.SqlClient.SqlCommand(queryString, sqlConnection) sqlCommand.Parameters.Add("@prod_code", System.Data.SqlDbType.VarChar).Value = prod_code sqlCommand.Parameters.Add("@prod_name", System.Data.SqlDbType.VarChar).Value = prod_name sqlCommand.Parameters.Add("@prod_desc", System.Data.SqlDbType.VarChar).Value = prod_desc sqlCommand.Parameters.Add("@prod_size", System.Data.SqlDbType.VarChar).Value = prod_size sqlCommand.Parameters.Add("@prod_price", System.Data.SqlDbType.VarChar).Value = prod_price sqlCommand.Parameters.Add("@prod_category", System.Data.SqlDbType.VarChar).Value = prod_category If chkAspnet.Checked = True Then sqlCommand.Parameters.Add("@aspnet","1") Else sqlCommand.Parameters.Add("@aspnet","0") End If Dim rowsAffected As Integer = 0 sqlConnection.Open Try rowsAffected = sqlCommand.ExecuteNonQuery Finally sqlConnection.Close End Try Return rowsAffected End Function Sub SubmitBtn_Click(sender As Object, e As EventArgs) If Page.IsValid then InsertProduct(txtCode.Text, txtName.Text, txtDesc.Text, ddSize.SelectedItem.value, ddPrice.SelectedItem.value, ddCategory.SelectedItem.value, aspnet.value) Response.Redirect("ListAllProducts.aspx") End If End SubAny help would be appreciated or links to tutorials.ThanksBen
i am use this query to select the primary field colums in a table "select Column_Name as PrimaryKeycolumn from INFORMATION_SCHEMA.KEY_COLUMN_USAGE WHERE TABLE_NAME = 'tbl_Activity' and Constraint_Name like 'PK_%'"
but i want to select the fields which have a nullable=false for that i want know the information schema for null
In a script task, I prompt the user for some parameters. I use the System::InteractiveMode variable to tell me if the package was launched via user interaction or from an automated process such as a file watcher. I display the prompts only if System::InteractiveMode is true. When I run from VS 2005 then I get the prompts, and when the package runs automated (dtexec) the prompts are not shown, so all is OK. However, when the package is run from dtexecui, I do not get the prompts because it seems the InteractiveMode value is false. Shouldn't the InteractiveMode value be true when the package is run from dtexecui since it is a user interface?
I want to pass a single char to a query and use that to set two flags.
(
@ID int,
@AssessedID int,
@CompetencyID int,
@Status char,
@Creator int
)
AS
UPDATE P4_Assessment
SET P4_Cancelled_f = (@Status = ('C')),
P4_Competent_f = (@Status = ('P')),
P4_Date = getdate(),
P4_Creator = @Creator
WHERE P4_ID = @ID
I want to set the P4_Cancelled_f to true (if @Status = 'C') or false if it doesn't. This sort of syntax is fine in C#, but fails in a query. I also tried using IN (@Status IN ('C'))
Is this sort of logic possible in TSQL or should I use two parameters and set them in my code as 1 or 0?
I've been pulling my hair out for the last couple of weeks trying to make my SSIS package more robust. I'm running SQL 05 SP1 on Windows XP SP2. Right now when there's a failure, the error propagates all the way up and my package stops running. Clearly not very robust. I have a heartbeat portion that makes a connection to the database every couple of minutes. Sometimes it loses the connection in the middle of the night, probably due to some maintenance going on. I have created an event handler to log the error, sleep a couple of minutes and set Propagate=False. This works great. When the connection is down, the error is logged, once the connection comes back, the package just keeps going. I also have an FTP component that receives a file and then needs to send back a handshake file. I tried the same method here, but the event keeps propagating up. I created an event handler for the Send FTP task itself, so that in case the remote FTP server isn't responding, it will error out. The Event Handler code is called and I verified that the value in Propagate is indeed False. And yet the event keeps propagating up and kills the whole package. FailPackageonFailure is set to False, FaileParentonFailure is set to False also. Any idea what I'm doing wrong? Or is this a bug? Is there a work around? Any help would be greatly appreciated.
If I use IRowsetFastLoad::Commit(FALSE) not IRowsetFastLoad::CommitCommit(TRUE), are there any limitation of IRowsetFastLoad::InsertRow(..) before Commit(FALSE)?
Now, I'm using everlastingly InsertRow(..) and Commit(FALSE) method repeatedly. A few days after, it seems not to work.
I need a way to test if a convert function will work before I process it. if it fails, I want to intercept the error and return my own error to the front end
I have two tables I am trying to compare as I have created a new procedure to replace an old one and want to check if the new procedure produces similar results.
The problem is that when I run my compare I get false matches. Example:
CREATE TABLE #ABC (Acct VARCHAR(10), Que INT); INSERT INTO #ABC VALUES ('2310947',110), ('2310947',245);
[Code] ....
Which gives me two records when I really do not want any as the tables are identical.
