vb.net data : Addnew in VB.NET ?
In VB6 to add a new record in a recorset, you can use the Addnew method,
then set each column's value, then call the Update method. How can I do this in VB.NET ? Thank you. VB6: Private m_rs As new ADODB.Recordset m_rs.Open "SELECT * FROM myTable", adoCon, adOpenKeyset, adLockOptimistic with m_rs .AddNew .Fields("ip") = AccountIP & " " ' x.Address .Fields("account") = Account & " " 'Left$(x.Key, 5) .Fields("DATEtime") = Now & " " .Fields("name") = userver & " " .Update end with

fniles,
Almost the same as I have answered this 4 hours ago to JNTP. To add a newrow to a table you can use in your case the newrow method. http://msdn2.microsoft.com/en-us/library/system.data.datatable.newrow.aspx (a sample how to do it is at this page at the bottom of the VB.Net part). Beside that exist too the dataview.newrow. http://msdn2.microsoft.com/en-us/library/system.data.dataview.addnew.aspx Cor "fniles" <fniles@pfmail.com> schreef in bericht news:%23g$ppwu0HHA.3916@TK2MSFTNGP02.phx.gbl...

Thank you.
When I tried it, when trying to update the database, it gave me the error "Update requires a valid InsertCommand when passed DataRow collection with new rows." This is what I do: Dim m_daSQL As SqlClient.SqlDataAdapter Dim m_cmdSQL As SqlClient.SqlCommand Dim m_dsSQL As DataSet Dim m_row As System.Data.DataRow m_cmdSQL = New SqlClient.SqlCommand With m_cmdSQL .Connection = adoCon .CommandText = "select * from myTable" End With m_daSQL = New SqlClient.SqlDataAdapter m_dsSQL = New DataSet m_daSQL.SelectCommand = m_cmdSQL m_daSQL.Fill(m_dsSQL) m_row = m_dsSQL.Tables(0).NewRow m_row("colA") = sValue m_dsSQL.Tables(0).Rows.Add(m_row) m_daSQL.Update(m_dsSQL) --> error "Update requires a valid InsertCommand when passed DataRow collection with new rows." Do I have to create an Insert Command in the SQLDataAdapter like so : m_daSQL.InsertCommand = New SqlClient.SqlCommand("INSERT INTO myTable (ColA) VALUES(?)", adoCon) myParm = m_daSQL.InsertCommand.Parameters.Add("@colA", SqlDbType.VarChar, 15, "ColA") ?

Thank you, that works.
This is what I do: Dim m_daSQL As SqlClient.SqlDataAdapter Dim m_cmdSQL As SqlClient.SqlCommand Dim m_dsSQL As DataSet Dim m_row As System.Data.DataRow Dim m_cmdBuilderSQL As SqlClient.SqlCommandBuilder m_cmdSQL = New SqlClient.SqlCommand With m_cmdSQL .Connection = adoCon .CommandText = "select * from myTable" End With m_daSQL = New SqlClient.SqlDataAdapter m_dsSQL = New DataSet m_daSQL.SelectCommand = m_cmdSQL m_cmdBuilderSQL = New SqlClient.SqlCommandBuilder(m_daSQL) m_daSQL.Fill(m_dsSQL) m_row = m_dsSQL.Tables(0).NewRow m_row("colA") = sValue m_dsSQL.Tables(0).Rows.Add(m_row) m_cmdBuilderSQL.GetInsertCommand() m_daSQL.Update(m_dsSQL) I am wondering which one is faster, using the code above (with sqlcommandbuilder) or use ExecuteNonQuery method of the SQLCommand like the following: Dim m_cmdSQL As SqlClient.SqlCommand sSQL = "insert into myTable (colA) values (sValue)" m_cmdSQL = New SqlClient.SqlCommand With m_cmdSQL .Connection = adoCon .CommandText = sSQL End With m_cmdSQL.ExecuteNonQuery() [quoted text, click to view] "Cor Ligthert[MVP]" <notmyfirstname@planet.nl> wrote in message news:0958E0AE-C135-407C-8B67-8ADE8EDF72A2@microsoft.com... > fniles, > > In my idea it is for this kind of simple updates the easiest and best to > use the commandbuilder. > > http://msdn2.microsoft.com/en-us/library/system.data.sqlclient.sqlcommandbuilder.aspx > > Cor > > "fniles" <fniles@pfmail.com> schreef in bericht > news:%23lqQEU40HHA.4184@TK2MSFTNGP06.phx.gbl... >> Thank you. >> When I tried it, when trying to update the database, it gave me the error >> "Update requires a valid InsertCommand when passed DataRow collection >> with new rows." >> This is what I do: >> Dim m_daSQL As SqlClient.SqlDataAdapter >> Dim m_cmdSQL As SqlClient.SqlCommand >> Dim m_dsSQL As DataSet >> Dim m_row As System.Data.DataRow >> >> m_cmdSQL = New SqlClient.SqlCommand >> With m_cmdSQL >> .Connection = adoCon >> .CommandText = "select * from myTable" >> End With >> m_daSQL = New SqlClient.SqlDataAdapter >> m_dsSQL = New DataSet >> m_daSQL.SelectCommand = m_cmdSQL >> m_daSQL.Fill(m_dsSQL) >> m_row = m_dsSQL.Tables(0).NewRow >> m_row("colA") = sValue >> m_dsSQL.Tables(0).Rows.Add(m_row) >> m_daSQL.Update(m_dsSQL) --> error "Update requires a valid InsertCommand >> when passed DataRow collection with new rows." >> >> Do I have to create an Insert Command in the SQLDataAdapter like so : >> m_daSQL.InsertCommand = New SqlClient.SqlCommand("INSERT INTO myTable >> (ColA) VALUES(?)", adoCon) >> myParm = m_daSQL.InsertCommand.Parameters.Add("@colA", SqlDbType.VarChar, >> 15, "ColA") >> ? >> >> Thanks. >> >> "Cor Ligthert[MVP]" <notmyfirstname@planet.nl> wrote in message >> news:D308C651-8B6C-4624-B32D-CA4FCC4B399A@microsoft.com... >>> fniles, >>> >>> Almost the same as I have answered this 4 hours ago to JNTP. >>> >>> To add a newrow to a table you can use in your case the newrow method. >>> http://msdn2.microsoft.com/en-us/library/system.data.datatable.newrow.aspx >>> >>> (a sample how to do it is at this page at the bottom of the VB.Net >>> part). >>> >>> Beside that exist too the dataview.newrow. >>> http://msdn2.microsoft.com/en-us/library/system.data.dataview.addnew.aspx >>> >>> >>> Cor >>> >>> >>> "fniles" <fniles@pfmail.com> schreef in bericht >>> news:%23g$ppwu0HHA.3916@TK2MSFTNGP02.phx.gbl... >>>> In VB6 to add a new record in a recorset, you can use the Addnew >>>> method, then set each column's value, then call the Update method. >>>> How can I do this in VB.NET ? >>>> Thank you. >>>> >>>> VB6: >>>> Private m_rs As new ADODB.Recordset >>>> >>>> m_rs.Open "SELECT * FROM myTable", adoCon, adOpenKeyset, >>>> adLockOptimistic >>>> with m_rs >>>> .AddNew >>>> .Fields("ip") = AccountIP & " " ' x.Address >>>> .Fields("account") = Account & " " 'Left$(x.Key, 5) >>>> .Fields("DATEtime") = Now & " " >>>> .Fields("name") = userver & " " >>>> .Update >>>> end with >>>> >>> >> >> >
fniles,
In my idea it is for this kind of simple updates the easiest and best to use the commandbuilder. http://msdn2.microsoft.com/en-us/library/system.data.sqlclient.sqlcommandbuilder.aspx Cor "fniles" <fniles@pfmail.com> schreef in bericht news:%23lqQEU40HHA.4184@TK2MSFTNGP06.phx.gbl...

But, with the sqlcommandbuilder, you need to select the table first, add the
row then update it, instead of just executing an "INSERT INTO" command using ExecuteNonQuery. You don't think the ExecuteNonQuery is faster ?

This part of the job in the updating takes on the client versus the netwerk aand server let's say 1:100 of the time, if you want speed, than look at the hardware how you can improve it. Just my opinion, Cor
