I have an application where I'm trying to store xml data in a db field defined as ntext. I have a dataset and table adapter setup in VSNet 2005 and SqlCe 3.1. When I look at the table adapter in the VS designer it shows the field with a type of String and a size of 2147483647 which appears to be correct. Also, if I look at the code generated by the MSDataSetGenerator tool it shows the parameter defined in the same way as in the following
param = new System.Data.SqlServerCe.SqlCeParameter();
param.ParameterName = "@Questions";
param.Size = 2147483647;
param.IsNullable = true;
param.SourceColumn = "Questions";
this._commandCollection[2].Parameters.Add(param);
My problem is that when I run the application and try to insert an item into this column the application throws an exception related to corrupted memory. Trying to debug the problem I found at run time, the param.Size value for the ntext parameter had been set to 255. Since the specific xml I was trying to insert was 410 characters in length I'm guessing that this is what is causing the crash.
Is the expected behavior (the setting of the size to 255 that is)?
If not, am I missing some trick here?
Hi, I am having the following problem AFTER converting to VS2008 from VS2005 and SQLCE 3.5 from 3.01: SQL CE 3.5 db file has a table called Court0 with various columns of type float. I populate the values by copying floats from another table/tables. I do this via ado.net using this code snippet:
if (columnName.Remove(1) == "T" && !string.IsNullOrEmpty(columnValue)) { // Add the value to the Court0 table. DataRow[] bRow = this.mycourtsDataSet1.Tables["Court0"].Select("BookingPeriod = '" + columnName + "'"); if (bRow.Length > 0) { double colValue = Convert.ToDouble(cValue); //bRow[0][tableName] = Convert.ToInt32(columnValue); ========> bRow[0][tableName] = colValue; <==== colValue is '1055.01' } } } } This works fine in VS2005/CE3.01 BUT not in VS2008/CE3.5 In CE3.5, the value entered into the cell looses it's decimal value. For example, '1055.01' becomes '1055.0' in CE3.5 . Can someone explain to me why the conversion stuffs up in CE3.5 and what do I do to fix it. Thanks,
I am running a Access97 front end with a SQL Server 7 backend. On records with an ntext datatype, you are only allowed to update records if the ntext field is null. The tables are linked from access. You get a "cannot update linked table" and "ODBC error #306." Any suggestions??
i have created asp.net page, one feild of this page text area. when i insert some text through this page in "text feild" of SQL server on few words of this feild cut and inserted to text feild of SQL server but all text that i have written in text area feild.
can u please help me how to handle so that i can all text in text feild of SQL server data type text/next.
I have to run a dynamic sql that i save in the database as a TEXT data type(due to a large size of the sql.) from a .NET app. Now i have to run this sql from the stored proc that returns the results back to .net app. I am running this dynamic sql with sp_executesql like this.. EXEC sp_executesql @Statement,N'@param1 varchar(3),@param2 varchar(1)',@param1,@param2,GO As i can't declare text,ntext etc variables in T-Sql(stored proc), so i am using this method in pulling the text type field "Statement". DECLARE @Statement varbinary(16)SELECT @Statement = TEXTPTR(Statement)FROM table1 READTEXT table1.statement @Statement 0 16566 So far so good, the issue is how to convert @Statment varbinary to nText to get it passed in sp_executesql. Note:- i can't use Exec to run the dynamic sql becuase i need to pass the params from the .net app and Exec proc doesn't take param from the stored proc from where it is called. I would appreciate if any body respond to this.
Hi, If I make a select query on my table, this error appears: "The data types text and varchar are incompatible in the equal to operator"
In my table , I have 4 fields with "text" datatype. My query is like : "Select * from table where field1='test'" It's seems to be simple, but it doesn't work!!!
Neither the SQLManagement Studio nor Visual Studio 2005 will open a 3.5 database. I understand that it's a "Orcas" technology but it works fine with vs2005 and Framework 2.0. I'm currently using VS2005 with CE 3.5 and using Rafik's Sync services, support for 3,5 would be a great help for the XSD and query creation.
Does anyone know when broader support for 3.5 will be available?
I´m exporting an ms-excel file, then I use a lookup transformation to get a field from a SQL Server 2005 table. The Lookup transformation editor, after selecting the table, shows a warning that says:
at least one mapping between a column from available input columns ans a column from available lookup columns must be defined on the columns page.
So I try to make a relationship in the Lookup transformation editor's column tab where I find the Available input columns and the available lookup columns but I get the following error:
The following columns cannot be mapped: [Department, DEP_CLEGALCODE] One or more columns do not have supported data types, or their data types do not match.
The field in SLQ Server is varchar(10) and the input field is a derived column transformation; I have tried different Data Types but I always have the same error.
The DataFlow is: ExcelSource --> Derived Column --> Lookup --> Flat file destination
I am currently upgrading our ppc app (written in .net 2003) to .net 2005 and from sqlce 2.0 to 3.0. The new application runs out memory(storage) when handling lots of data transactions (both in case of using sqlcedatareader, and dataset ). There is no memory leak issue here, sqlce 3.0 simply uses a lot more (3 times more) memory than sqlce 2.0.
Our applicaton runs fine using sqlce 2.0 and .net 2003, but fail due to memory shortage
with the upgrades(which has the same code). Anyone can shed some lights on this issue?
I am running this query to an sql server 2000 database from my aspcode:"select * from MyTable whereMySqlServerRemoveStressFunction(MyNtextColumn) = '" &MyAdoRemoveStressFunction(MyString) & "'"The problem is that the replace function doesn't work with the ntextdatatype (so as to replace the stresses with an empty string). I hadto implement the MySqlServerRemoveStressFunction, i.e. a function thattakes a column name as a parameter and returns the text contained inthis column having replaced some letters of the text (the letters withstress). Unfortunately, I could not do that because user-definedfunctions cannot return a value of ntext.So I have the following idea:"select * from MyTable whereCheckIfTheyAreEqualIngoringTheStesses(MyNtextColum n, '" & MyString &"')"How can I implement the CheckIfTheyAreEqualIngoringTheStessesfunction? (I don't know how to combine these functions to do what Iwant: TEXTPTR, UPDATETEXT, WRITETEXT, READTEXT)
When I enter over 4000 chars in any ntext field in my SQL Server 2005 database (directly in the database and through the application) I get an error saying that the data could not be updated because string or binary data would be truncated.Has anyone ever seen this? I cannot figure out what is causing it, ntext should be able to hold a lot more data that this...
I have a column in SQL server which is of type ntext. Selecting the specific column to view it in report builder, an error message appears with the following description:
- Cannot run this report. The grouping expression 'nameofcolumn' returns the datatype binary. The Grouping Expression cannot return binary data.
Report Builder recognises this as if it was an image...
Hi All, I have just installed SQL Server Compact Edition (including the SDK) for use with Borland Developer Studio 2006. I have an ADOConnection component on my form, but the Provider I want (Microsoft.SQLSERVER.MOBILE.OLEDB.3.0) is not available. Typing in the connection string: "Provider=Microsoft.SQLSERVER.MOBILE.OLEDB.3.0;Data Source=C:Program FilesMicrosoft SQL Server Compact Editionv3.1SDKSamplesNorthwind.sdf..." results in an "Unspecified Error". I have checked the HKEY_CLASSES_ROOTCLSID and the provider associated with SQLCE is not there. I've read a couple of posts indicating that it should have been registered during install. Is this the case or do I have to do something more to register this provider? I've checked the assembly (system.data.sqlserverCe - it seems OK) and re-registered sqlceolebd30.dll. I'm not sure what else needs to be done. TIA, Luke
We are building a near real time application in Windows Forms, that stores data in SQL Compact Edition. The client receives messages via UDP socket and performs insert / update operations to the db accordingly, and the requirement is to update a data grid with the changes.
We tried querying the db and receive a ResultsSet which is sensitive and scrollable, and bind a ResultSetView to the Grid. But, since the updates are made from another thread, the grid is not being refreshed.
What is the best approach for achieving this?
Thanks in advance,

My organization have a web-based application and needs it to support multilingual so we will be adapting our app to use unicode. However, one of our problems is to convert existing data from text to ntext. I couldn't find anything that document this. What is the best way to do that? I would like to be able to migrate the data from an existing text column to another ntext column in the table.
I brief you about my system, I used List manager system to store the messages and distribute to all members. Right now,by design the Lyris system keep the message in the text field which mean it 's not support multilanguage directly because of unicode field. We needs to create new Db which has the data structure as same as Lyris but just one difference is keep the message in unicode format (ntext) which we need the sql script to automatically update the new record get from Lyris to new DB.
If I can't do that, what are the options? If it's possible, I would like to be able to do this in sql script.
Why System.Data.SqlserverCe.Dll doesn't appear in VS2005. In VS2003 System.Data.SqlserverCe.Dll appear to write winCE application. But it won't appear in VS2005 while am selecting PocketPc application. any body gimme the solution.
The sql database has an ntext (16) field which contains "information" and is used as a free form turnover log. When I bring this data into an ASP page the "information" gets truncated.
I have tried getchunk, however all formatting on the field is lost. I have tried putting the field at the end of my query - no change. I have tried querying the data as a separate sqlrs connection - no change. I have tried using substring to break it down, the first substring works, however I get errors on the second (Expression result length exceeds the maximum. 8000 max, 12000 found).
I also tried to use substring in sql query anaylzer - and only get the first ~4180 characters.
Is there a way to split this field into multiple nvarchar fields in my temporary table in sql and then concatenate back together in asp report???
Hello . Because of my graduation project , I interested in data mining application , Adventureworks DW on MS VS 2005 . I opened File->Open->project/solution ->Enterprise -> AdventureworksDW .then I successfully deployed the algorithms decision tree and Clustering . Then I opened tab Mining Accuracy Chart then selected input table "testing" , which I had created before , from vTargetMail . After that , mining structure table and target mail table has automaticaly linked each other .Next , I selected predictive input as 1 , of the predictable row "BikeBuyer" . But , when I clicked "Lift Chart ", I only got a 45 degree line , everytime .. How can I fix it ?
I have some text in an NText column that could be quite long.
for the web page that displays it, i want to show the first 200 characters and then have a "more..." link to bring up the full text.
i'd like to create a stored procedure that takes the left 200 characters and copies them to a ShortText column (NVarChar) for initial display and then id like to set a bit column to indicate if the length of the NText column is greater than 200.
Len and Left cant be used against NText so how can i work with the NText data ??

Have a table storing nText data tied into a Cold Fusion front end. The Cold Fusion returns the values fine, but when querying in Query analyzer the messages are being truncated. In Enterprize Manager I get a <Long Text> message.
I ran OBJECTPROPERTY and found that TableTextInRowLimit was set to 0, but even after i set it to 1 on our test system with a value of 2000, it still truncated.
Also, the field is set to ntext with a length of 16. I havent worked much with nText, anyone with advise would be much appricated.
We have a Compact Framework 1.1 application that uses Sql Server CE 2.0. In VS2003, a reference to System.Data.SqlServerCe causes the Sql Server CE dlls and Query Analyzer to install to the Emulator or PDA.
I am currently converting the application to Compact Framework 2.0, but we are not upgrading to Sql Server Mobile (yet). However, the reference to System.Data.SqlServerCe, in VS 2005, no longer causes Sql Server CE to install to the PDA/Emulator.
There is a difference in the build outputs between VS2003 & VS2005. In 2003, System_SR_enu.cab, sqlce.wce4.x86.cab & sqlce.dev.wce4.x86.cab are copied & lanuched. In 2005, only System_SR_enu.cab is copied... no launch.
I am trying to find a reference for a client that lists the fields available to be substituted into a data driven subscription from the query, along with the expected data types.  For example, the field on whether or not to include a link to the report seems to be expecting a bit data type.I have searched and can't seem to find anything.  I guess I could walk through the interface and try different data types, but if  a list exists, that would be better.Â
While run time these values are lets suppose @SSN = '999-000-000' & @State='ABC'
Now the Result is displayed with the state data Like 'AB' only.
Output: 1 999-000-000 AB
instead it should give system generated error.
Here I have 2 Questions: 1. Why it is taking 1st 2 Charecters? 2. Why it does not have any system generated for length?
I can do validation with Length function for these 2 variables however if have 100 variables then it should not feasible case. So, what is the reason behind?Â
I am having a problem writing a large amount of ntext data to a field within an ADO recordset. I am using the append chunk method but it does not seem to work. The SQL 7 field will hold the data its only about 60K.
