Importing Data Using SQLBulkCopy?
May 25, 2012
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'm looking to pull data off of a webpage that gives the data in comma delimited values.
I want to pull that data off, and I'm sure I'll have to store it in an array.

I am importing data from Excel to a datagrid in VB, I can get the data on there no problems and also save this back to a SQL database without any problems.
However I have a new spreadsheet which has the same product listed again and again with the same description but different totals, what I want to do is to upload this to the datagrid just once for each description, with a grand total of all the seperate totals

I am trying to import data from a server and put it into an excel sheet. I have included (imported) the Microsfot.Office.Interop package into my program. I have been looking through the Object Browser to find the correct commands to add this imported data. Should the ListColumns.Add and Listrows.Add functions be used in this spot? I have started a code however, it was initially going to be used with human interaction. The new direction is to make it automated. The section of code I have written follows:
#Region " (Import Data) This function will import the PI Tag Names and desired Attributes into an Excel worksheet "
Private Sub Import()
[Code]...
After the nvs.Add("changer", 1) there are many more attributes that are going to be added to the excel file but I did not feel they needed to be shown here.

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.

I have been trying for several months (in my spare time) to write a vb.net (version 2010) program that connects to Excel (version 14) and imports numerical data.This data will be used later for engineering calculations.I have tried the Interop code which I have found on the internet with limited success and now I am trying the connection string method.I have found some examples of code, on the internet,that I have pieced together and can't get it to run.Below is that code.
Imports System.Data.OleDb
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click[code].......
This is a screen image of the error I get when trying to run the program.

I need to import data from Excel worksheet into the VB.Net program. First, I need to get the data to some array or arraylist and secondly to show the data to user through datagridview or similar.So far, I have this
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim myDataset As New DataSet()
Dim strConn As String = "Provider=Microsoft.Jet.OLEDB.4.0;" & "Data Source=C:TempTest.xls ;" & "Extended Properties=Excel 8.0;"[code].....
How can I adjust the code to manage that? And how can I import the same range to variables (the range contains approx. 200 rows and 30 columns of data points) and I need the flexibility to add or delete items (rows) from the data in memory later.

How can I read data from a .csv file I have opened into a variable for later use (i.e. plotting with zedgraph)? My csv file contains 100+ columns and 12000+ rows of data, with each column a different variable.
I've searched around a ton on this subject, and combined many methods I found on the net to my project but none actually do what I am required to do.

I'm sure this is a common problem but I have been unable to find a good solution anywhere.I am using line.Split to read a CSV file.Unfortunately the data contains strings that have comma's in them like so:
"Singer","Hasselhoff, David",21,15
This results in 5 strings:
Singer

I have an xls file that needs to be imported into SQL Server directly from .net. I figured out how to do this, but now my problem is the data. The following data is in the xls file: Name, Address, City, State, Zip, Phone. The phone number can come in in various values(with dashes and without). I have no way of controlling this data because it is an export out of some third party application. My problem is that the numbers with the dashes are being ignored by the Excel import. I am using the OPENROWSET to import.

I start with a text file containing information such as this: Monday, Tuesday, Wednesday, Thursday, Friday 12:00:00.1, 12:00:00.1, 12:00:00.1, 12:00:00.1, 12:00:00.1 I made up the values of course but the idea is exactly the same. I need to have an if statement that if the text document has a record of Monday, then it is to put something like an X in the corresponding column in a data table. I'm sure I confused this way more than need be but I hope you get the most of it and I can elaborate if need be.

I have a table in my database. I have an import routine which reads rows from and XML file. It first loops through my existing table to see if the row exists using a date and store code column as a unique id. It all works fine until this senario occurs.First file is read in and a new row is added for 01/03/2011, store code 100. The second file is read in which also has a row with 01/03/2011, store code 100. But when I loop through it does not find the row I just added so it adds it again.The only solution I can think of is to re-populate the local table everytime I add a new row but this will have a massive amount of over heads.If I add a row to an existing dataset surely if I loop through that dataset I should come across it.

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 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)
