.net SqlBulkCopy With Unicode Chars
Nov 29, 2010
i have a csv file that needs to be imported to sql server the file includes Unicode characters, so i saved it in notepad as Unicode now when i run this in sql it works excellent BULK INSERT personimps FROM 'C:MyImp.csv' WITH (FIELDTERMINATOR = ',',datafiletype='widechar')but when using the following in my code-behind in asp.net, i get gibberish where the Unicode chars should be. [code] it seems like the oledbconnection is ignoring the extended properties, or maybe i didn't set up the connection-string correctly? the ASCII chars come out OK, the Unicode fields are just gibberish.

I was wondering if it was possible, in a console application, to write characters like "℃" using .NET? When I try to write this character, the console outputs a question mark.

In VB.net I've got the following line that removes all non-alphanumeric chars from a string:
return Regex.Replace(build, "[W]", "")
I now need to extend this to remove non-alphanumeric chars that aren't [] or _. I've changed the line to:
return Regex.Replace(build, "[W[]_]", "")
However I'm pretty sure that this says
replace non-word or [ or ] or _
how do I negate the tests for the [] and _ chars so that it says
replace non-word and not [ and not ] and not _
Some examples:
"[Foo Bar_123456]" => "[FooBar_123456]"
"[Foo Bar_123-456*]" => "[FooBar_123456]"

I'm using SQL Server 2005, VB.NET 2005. I want to be able to import a very large excel file into a SQL table called "XYZ"
I've done this by doing the following:
1. Save the excel file as csv.(Using SaveAs XLCSV option)
2. Build a datatable "ABC" From CSV.(using ODBC Connection and Select * from '*'.csv command)
3. copy the datatable"ABC" into database table "xyz" (using sqlBulkCopy.WriteToServer())
It works fine without any error but when i checked my database i found that data type for some columns has been changed and hence it didn't copy some of the records.

We are getting the following error (only on the staging server) when we use SqlBulkCopy. The stored procedure has execute permissions. And they are working properly in our test environment. So what is the setting to be corrected in stage environment to work it properly?

We have a legacy application that is dumping large volumes of data to tab delimited files.Each file contains a single record type and all fields are fixed length.These files can readily be imported into corresponding tables in our SQL server database using the BCP utility from the command line.We have a VB.Net program written in VS 2003 that imports these files using the SQLDMO.BulkCopy routine. We are updating the system to use VS 2010 with SQL Server 2008 and according to the Microsoft documentation SQLDMO is no longer available.I have searched on the internet and have rewritten the import routine to import the tab delimited files into a DataTable using the Microsoft.Jet.OLEDB.4.0 provider. The SqlClient.BulkCopy object is then used to import this DataTable. This issue I am having is that fields in the tab delimited file that are set to spaces are being treating as NULLs when imported into the DataTable. When the DataTable is processed by the SqlClient.BulkCopy the copy fails because the null values are rejected by the SQL table fields that are defined as NOT NULL.Code being tested is shown below
Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
Dim data As DataTable = RetrieveSourceData()

I have a .csv file that is selected using the OpenFileDialog that then populates a ataGridView. The .csv file is then visible for the user to check a number of things. This part works fine.What I then need is once it is checked the user then needs to click a button to import this into my SQL Server table (CSV_Import). I have looked at SQLBulkCopy but am failing to get the data imported.Here is some code I have picked up and I am guessing that it is the bc.WriteToServer(dt) needs correcting within the brackets but I am at a loss at this point.
bc.BatchSize = dt.Rows.Count
bc.DestinationTableName = "CSV_Import"
bc.WriteToServer(dt)

I am trying to sqlbulkcopy. I have a dataset defined (.xsd). It seems that I cannot use it with sqlbulkcopy. All the information I can find on sqlbulkcopy shows that it can only take a connection string or a variable that contains the connection string.

In a VB.NET, I code to exec a store procedre (sp_truncate) to truncate 10 tables and using sqlBulkCopy to download a huge data. Both them are working fine. Now I want to use transaction with vb.net (not in store procedure?) to rollback truncate tables if download is failed. Is it possible to use transaction to work with these two steps?

I used sqlbulkcopy to upload huge data from local to remote. It works great.The only problem is that there is a table tClaim in which there are 50 columns. One clumn "IsUpload" do not need to upload. How to upload all columns except for this column? If I use columnmappings, do I have to code add column one by one?

I was wondering if the following is possible. In a particular operation I want to create a dataset, bulk copy it to another SQL Server, then update a flag column in the copied rows.I'll have a system that will be regularly inserting new rows of data, then at regular intervals want to copy that data to another SQL Server. Once the rows have copied I need to change a flag column so that they won't get copied again.Whilst this is going on there is a strong possibility new rows of data will be being inserted into the source table. These new rows will be copied at another interval.

Well my question is simple and straightforward. Is there any way we can use hex values like in c++?
I am going to write binary files, but for that i will have to define certain characters like this for example.
x00x00x11x22x33x00x00. I would first need to convert stuff like this to a byte array, and then write it to a binary text file.

I am using a masked text box to format phone numbers. However, I do not want the extra formatting that gets insterted from the masked text box: (800)-555-1212
All I want is: 8005551212
But I still want the user to type it in like this (to make it easier for user):
(800)-555-1212
I am thinking I can run a replace function on it, but I am not sure what event to use. I found a number of tutorials, but not that useful for what I am doing. [URL]
