sql server - Malfunction of data copy from excel to Sql using BulkCopy (vb.net) -


i'm searching reason why importation excel sql table not working (via vb.net)

the excel file in input contains 1300 rows , 12 columns. 5 last columns contains prices. after importation, table if filled excel data except 2 last "price" columns data 'null'. strange thing "price" columns in sql destination table formatted same type (decimal(18,2)), in excel file. copy, use sqlbulkcopy , wonder if function not limited.

here's code:

        dim excelconnection new system.data.oledb.oledbconnection("provider=microsoft.ace.oledb.12.0;data source=" & ftransp & ";extended properties=""excel 12.0 xml;hdr=yes""")          excelconnection.open()          dim requeteexceltransp string = "select * [excelcetup$]"          dim objcmdselect oledbcommand = new oledbcommand(requeteexceltransp, excelconnection)          dim objdr oledbdatareader          using bulkcopy sqlbulkcopy = new sqlbulkcopy(connexionlinkystat)             bulkcopy.destinationtablename = "dbo." & tabletransp & ""              try                 objdr = objcmdselect.executereader                 bulkcopy.writetoserver(objdr)                 objdr.close()                 connexionlinkystat.close()              catch ex exception                 msgbox(ex.tostring)             end try         end using          excelconnection.close()

i trying 1 code, hope code helpful project

private sub button1_click(byval sender system.object, byval e system.eventargs) handles button1.click

     dim myconnection system.data.oledb.oledbconnection     dim dtset system.data.dataset     dim mycommand system.data.oledb.oledbdataadapter      dim fbrowse new openfiledialog     fbrowse         .filter = "excel files(*.xlsx)|*.xlsx|all files (*.*)|*.*"         .filterindex = 1         .title = "import data excel file"     end     if fbrowse.showdialog() = windows.forms.dialogresult.ok         dim fname string         fname = fbrowse.filename         myconnection = new system.data.oledb.oledbconnection("provider=microsoft.ace.oledb.12.0; data source='" & fname & " '; " & "extended properties=excel 8.0;")         mycommand = new system.data.oledb.oledbdataadapter("select * [sheet1$]", myconnection)         mycommand.tablemappings.add("table", "test")         dtset = new system.data.dataset         mycommand.fill(dtset)          myconnection.close()         each drr datarow in dtset.tables(0).rows             execute_local("insert excel(name, designation, salary) values ('" & drr(0).tostring & "','" & drr(1).tostring & "','" & drr(2).tostring & "')")         next         msgbox("successfully saved")      end if    end sub`
