I want to bulk insert a csv file into sql database (asp.net with vb.net) with the code below but it gives me this error (Incorrect syntax near 'C:'.)

VB

Using con1 As New  SqlConnection(ConfigurationManager.ConnectionStrings("connection").ConnectionString)
           Dim csvPath As String = Server.MapPath("~/excel/") + Path.GetFileName(FileUpload1.PostedFile.FileName)
           FileUpload1.SaveAs(csvPath)
           con1.Open()
           Dim queryimg As String = "BULK INSERT trycsv FROM " + csvPath + ""
           Dim cmdimg As New SqlCommand(queryimg, con1)
           cmdimg.ExecuteNonQuery()
           con1.Close()
       End Using

Please save my day.

Solution 1

try below

VB

Using con1 As New  SqlConnection(ConfigurationManager.ConnectionStrings("connection").ConnectionString)
           Dim csvPath As String = Path.Combine(Server.MapPath("~/excel/") , Path.GetFileName(FileUpload1.PostedFile.FileName))
           FileUpload1.SaveAs(csvPath)
           con1.Open()
           Dim queryimg As String = "BULK INSERT trycsv FROM '"+ csvPath + "'"
           Dim cmdimg As New SqlCommand(queryimg, con1)
           cmdimg.ExecuteNonQuery()
           con1.Close()
       End Using

I have include single quotes for file path
UPDATE:
As below Kornfeld Eliyahu Peter pointed out about path,
above will work if your web server and the sql server both run on same sever/PC
check Handling BULK Data insert from CSV to SQL Server[^]
you can find sample code which you can bulk insert using csv reader and that will solve your issue.

You probably right about the quotes as the source of the syntax error, however the main problem is that OP saves the files on the WEB SERVER's disk where BULK INSERT will look for it on the DB SERVER's disk...

is it? then how does windows form applications do the bulk insert?

"data_file must specify a valid path from the server on which SQL Server is running. If data_file is a remote file, specify the Universal Naming Convention (UNC) name. A UNC name has the form \\Systemname\ShareName\Path\FileName. For example, \\SystemX\DiskZ\Sales\update.txt."
Quoted from here: http://msdn.microsoft.com/en-us/library/ms188365.aspx
It means you have to save the file in a shared place to BULK INSERT to work...
