Insert Unicode Data Into The Database With Typed DataSet
Dec 11, 2006
Hi all,
I am using a Strongly Typed DataSet (ASP.NET 2.0) to insert new data into a SQL Server 2000 database, types of some fields in db are nvarchar.
All thing work fine except I can not insert unicode data(Vietnamese language) into db.
I can't find where to put prefix N.
Please help me!!!
I am trying to upload a file in ASP.net 2.0 to a SQL database using the FileUpload control. I am doing this by way of a typed dataset.Here is my code.Dim rta As New ResponseTableAdapterDim rdt As ResponseDataTable = rta.GetResponseByID(1)Dim rr As ResponseRow = rdt(0)Dim fs As New FileStream(fu.PostedFile.FileName, FileMode.Open, FileAccess.Read)Dim br As New BinaryReader(fs)Dim image() As Byte = br.ReadBytes(fs.Length)br.Close()fs.Close()rr.UploadFile = imagerr.NameFile = fs.Namerta.Update(rdt)The code runs without an error but afterwards I find that nothing has been stored in the UploadFile cell in the database but the file name has been stored in the NameFile cell in the database. Any ideas?Your help is much appreciated. James
Hi, Is there any work around to passing a set of strings to a parameter in a Typed Dataset for example I am pasing '4226222172004','4212012182004' which I build on my code the number of items will vary passed on the user selection but since the Typed Dataset uses sp_executesql and the parameters are change to '''4226222172004'',''4212012182004''' Any ideas how I can format the Parameter I am passing.so that it will end like where in ( '4226222172004','4212012182004') instead of where in ('''4226222172004'',''4212012182004''') I again the number of parameters will very. Thanks Julio D
When I insert the fields using parameters, the params look like this: paramValues(10) = New SqlParameter("@RegHrs", SqlDbType.Decimal) paramValues(11) = New SqlParameter("@OTHrs", SqlDbType.Decimal) paramValues(12) = New SqlParameter("@TotHrs", SqlDbType.Decimal)
The fields in the SQL table are defined as: RegHrs - decimal (9,2) OTHrs - decimal (9,2) TotHrs - decimal (9,2)
Before I insert the row (from w/in the VB code), I stop the code and verify that the values being placed into the params are: 5.85 0 5.85
After the SQL insertion, the values w/in the SQL Table contain: 6 0 6
Hi, I am trying to use a typed dataset created using the Query builder which returns the data correctly when I use 'Execute Query' in query builder but as soon as I attempt to return a dataset using the GetData method created I get the following error: Failed to enable constraints. One or more rows contain values violating non-null, unique, or foreign-key constraints. Which is not very helpful, any ideas where the problem may be? I have tried switching off enforce constraints and setting the NullValue property of all strings to 'Emtpy' bu that has no effect. Thanks in advance
Hello,I'm using a typed dataset to access my database (SQL Express); I have a table that returns data, which two fields are null; I'm getting this error:{"Failed to enable constraints. One or more rows contain values violating non-null, unique, or foreign-key constraints."}There are no foreign-key or unique key constraints, so it has to be a non-null issue; I changed the two fields in the table to have a null value of Empty instead of Throw Exception, but I don't understand what the problem is coming from... I'm at a loss.Thanks.
I'm need to use typed Dataset with CLR UDT, but when I'm trying to create TableAdapter in Dataset designer, I'm gettng error message: User-defined data types are not supported in DataSet designer
Hi, I have a little question. I searched google, and could not find good answer for this one. I have a stored procedure that returns two tables. Usually I generate a dataset out of a stored procedure by dragging it to the dataset. When I drag this one it creates a DS with only one table, the first one. How can I make it use both tables?
Using VS 2008 Beta 2, SQL CE 3.5, on desktop, and Typed Datasets: The INSERT command of dataset table adapter does not return the updated identity of inserted row. Why?
also every time I want to modify the insert command to return the updated identity of inserted row, i get the error: "Unable to parse query text."
I'm at loss how I'm supposed to work with typed datasets and Sql Server Compact 3.5, when inserting records and I need to update my datatables with the primary key of newly inserted rows.
I've tried adding a RowUpdated handler to all tableadapters that look like this:
I've previously used this type of approach when working with an OleDbDatabase, which works just fine. But it doesn't work with Sql Server CE 3.5, and since it doesn't support stored procedures I can't fix it that way either. And it doesn't support commands in a batch (i.e appending the Insert command of the adapter with ";SELECT @@IDENTITY") so that doesn't work either...
So how are we supposed to use Sql Server CE 3.5? It's impossible together with datasets? Or am I missing something obvious?
Like the subject says, I'm using strongly typed datasets. I'm using to designer to create the datasets and the methods. I can select and insert, but I can't update or delete. I right click on the adapter bar and select Add Query. I sleect 'Use SQL Statements'I select 'Update' (or 'Delete')I get a sql statement pane containing the word 'Update' ('Delete') and asking 'What data should the table load?'I can click on next, but anything else gives me errors. I'd list them, but I'm clearly doing something wrong and it's probably obvious. Diane
I am following the SSIS overview video- URL...I have a flat file that i want to import the contents onto a SQL database.I created a Dataflow task, source file and oledb destination.I am getting the folliwung error -"column "A" cannot convert between unicode and non-unicode string data types".in the origin file the data type is coming as string[DT_STR] and in the destination object it is coming as "Unicode string [DT_WSTR]"I used a data conversion object in between, dosent works very well
I have an SSIS package that pulls data from a MYSQL DB (Using RSSBus for Salesforce in SSIS to accomplish this). Most of the columns are loading properly, but I have many columns that I need to convert.
I have been using the Data Conversion dataflow task in SSIS to convert the rows.
I have 2 data conversions that work on most of the columns, but the DESCRIPTION column continues to return an error saying "Cannot convert between unicode and non-unicode types", regardless of what I choose on the Data Conversion task. So, basically I want to dump this column data into a SQL table with NVARCHAR datatypes. Here is what I am doing in my SSIS package...
1) Grab subset of data from SOURCE 2) Converts to TEXTSTREAM. (Data Conversion) 3) Converts to STRING. (Data Conversion) 4) Load Destination table. (OLE DB Destination)
I have also tried to simply convert the values to STRING, but that doesn't work either.
So, I have 2 Data Conversions working here that process most of the data correctly. What I can do to load the DESCRIPTION column?
I've had some great headaches with SSIS this morning, which I have managed to get a workarounds for, but I'm not happy with them so I've come to ask for advice.
Basically, I am exporting data from an SQL Server database into an Excel spreadsheet and hitting issues with unicode and non-unicode data types.
For example, I have a column that is char(6) and have added a data conversion step to the data flow, which converts it to type DT_WSTR and then everything works!
However, this seems like a completely un-neccessary step as I should be able to do the conversion in T-SQL - but no matter what I try I keep getting the same problem.
SELECT Cast(employee_number As nvarchar(255)) As [employee_number] FROM employee WHERE forename = 'george'
ErrorValidation error. details: 1 [1123]: Column "employee_number" cannot convert between unicode and non-unicode string data types.
I know I have a solution (read: workaround) but I really don't want to do this everytime!
I have an Excel Source component hooked to an OLE DB Destination component in my SSIS 2005 Data Flow Task. After I mapped the excel columns to the OLE DB table columns i get these errors below. I noticed that for the first error, the Excel Field format (when you mouse over the column name in the mappings section in OLE DB component) is of type [DTWSTR] and the corresponding SQL field from my SQL table that it's mapping to is of type [DT_STR] when mousing over that field in the mappings in the properties of my OLE DB component. All table fields in SQL Server for the table I'm inserting into are of type varchar.

I use Visual Studio's, integration project to load XML file into SQL Server. In the XML file, i have defined collumns as string. When i try to load XML file with parts defined in scheme as string, i get an error "cannot convert between unicode and non-unicode string data type.
Destinated collumns in SQL are defined as varchar and char.
I have spent countless number of hours trying to solve the issue, but to no vail. My problem is SSIS throws "cannot convert between unicode and non-unicode string data types" when i am try to transform data from DB2 to SQL Server 2005. And please note, i tried all possibilities like changing the destination field which is in SQL Server 2005 to nvarchar and also text. But so far no help. And i also looked at previous posts which did not help me either.
I have a code to update an access database from one of my dataset tables, but i want to insert columns manually
currently i am using this code to update my db
Dim cb As OleDb.OleDbCommandBuilder = New OleDb.OleDbCommandBuilder(dtadpt)
AccessConn.Open()
dtadpt.Update(DataSet, "recordsforupdate")
AccessConn.Close()
this code automatically inserts all the columns of dataset table to the access database table.
what i want is to inset the values for eg. in col4 of my dataset table into col5 of my access table, for that i want to manually use "inset into" statement to update the db table, but i am having problem with the syntax for using dataset..can anyone help please
Hi all, we are now planning to upgrade our application from anon-unicode version to a unicode version. The application's backend isa SQL Server 2000 SP3.The concern is, existing business data are stored using collation"Chinese_PRC_CI_AS", i.e. Simplified Chinese. So I thought we need toextract these data out to the new SQL Server which is using Unicode (Iassume it means converting them to nchar, nvarchar type of fields for Idon't enough information from the application side, or is there ageneral unicode collation that will make even char and varchar types tostore data as Unicode?).The problem is what's the best and most efficient way to do this dataconversion?bcp? DTS? or others?thanks a lot
I am using typed data sets. When a certain line of C# code is reached, I get the following error message: Failed to enable constraints. One or more rows contain values violating non-null, unique, or foreign-key constraints. Here is my source code. I altered the table to remove all contraints and primary keys, but I still get the error message. The erroroccurs when the last line of code is reached. (_DeltaTable = myAdaptor.GetData();) The code is listed below. Does anyone know whatis going on? calculateValuesAndAveragesTableAdapters.FundamentalsTableAdapter myAdaptor = new calculateValuesAndAveragesTableAdapters.FundamentalsTableAdapter(); calculateValuesAndAverages.FundamentalsDataTable _DeltaTable; _DeltaTable = myAdaptor.GetData(); // Error occurs on this line
I would like to extact data from a source system even if it has errors. Then I can transform it and handle the errors in the appropriate manner. Are there any loosely-typed Data Flow Destinations?
Hi there.We have an application that can run on a non-unicode or a unicode sqlserverdatabase.Currently the application is running in a unicode database, as anon-unicode database is less than half the size, I would prefer tohave a non-unicode database for demo purposes to be on my laptop, etcetcIs it possible to change a unicode sql server 2000 database into anon-unicode database?And if so, how would I go about doing this?Any help would be greatly appreciated.ThanksRodger
I'm new at this so I apologize in advance for my ignorance.
I'm creating a website that collects dates in a calendar control (from Peter Blum). When the page containing the control loads it populates the calendar with dates from the database (that have previously been selected by the user). The user then can delete existing dates and/or add new dates.
I create a dataset when the page loads and use it to populate the calendar. When the user finishes adding and deleting dates in the calendar control I delete the original dates from the dataset and then write the new dates to the dataset. I then give execute the data adapter update command to load the contents of the dataset back into the database. This command involves using parameterized queries. For example the Insert command is:
Dim cmdInsert As SqlCommand = New SqlCommand("INSERT INTO Requests VALUES(@fkPlayerIDNumber, @RequestDate, @PostDate, @fkGroupID)", conn)
nsert and Update Unicode Below I write some line of my SP But I does not write Unicode data to table, it writes like ???????? How can avoid this problem
SP header:
CREATE PROCEDURE ltrsp_AddEditUnit @UnitID char(4), @UnitName nvarchar(20), @UtrID int
Insert:
INSERT INTO ltrtb_Unit (UnitID,UnitName,UtrID) VALUES (@UnitID,@UnitName,@UtrID)
Update: --- UPDATE ltrtb_Unit SET UnitName=@UnitName,UtrID=@UtrID
Here is the situation, please let me know if you have any tips:..TXT files in a share at \fooSPROCS run daily parses of many things, including data on that share. Theother day, we encountered rows in the TXT files which looked like:column1Row1data,column2Row1datacolumn1Row2data,column2Row2data...etc..However, column2 was about 6000 bytes of unicode. We are bulk insertinginto a table specifying nvarchar(4000). When it encounters high unicoderows, it throws a truncation error (16).We really need information contained in the first 200 bytes of the string incolumn2. However, the errors are causing the calling SPROC to abort.Please let me know if you have any suggestions on workarounds for thissituation. Ideally, we would only Bulk Insert a sub-section of column2 ifpossible.Thanks!/Ty
I have been racking my brain over this hopefully someone has run into a similar issue. I am attempting to Bulk insert several Unicode (UCS-16BE) data files that are missing their Unicode Signature. If I add a Big-Endian signature (FE FF) I can get the files to load into a table without using a format file, but if I attempt to use a format file I get the following error ( I need to use a format file due to more columns in the actual table than in the file):
Msg 4832, Level 16, State 1, Line 1 Bulk load: An unexpected end of file was encountered in the data file. Msg 7399, Level 16, State 1, Line 1 The OLE DB provider "BULK" for linked server "(null)" reported an error. The provider did not give any information about the error. Msg 7330, Level 16, State 2, Line 1 Cannot fetch a row from OLE DB provider "BULK" for linked server "(null)".
If I attempt to load without the Unicode signature, with a format file the correct number of characters load into the fields, but the data is all €˜€™s. I have tried various codepages (including 1201 & 1200) and codepage settings and none have any effect on the data that is loaded or not loaded.
Code Using Format File: BULK INSERT [ARE_Test_Stage].[dbo].LFBK FROM 'U:ProjectsTempUnicodeTest2 est-w.TXT' WITH ( DATAFILETYPE = 'widechar', CODEPAGE = '1201', MAXERRORS = 2147000000, FORMATFILE = 'U:ProjectsTempUnicodeTest2FormatFiles est-w_METADATA.fmt', KEEPNULLS )
