Chris Holland SEC Solutions Ltd. ![]() | The RS RecordSet is a "SELECT" statement.
To change the data in the table you will need to use either an "INSERT" or and "UPDATE" command. As this code is in Visual Basic, something that I know nothing about I cannot give you an example. If you search the internet you should find plenty of examples of how to change data in VB using ODBC drivers Chris Holland Deneys wrote: > Hi to all > > Please could some one help ? > > I have the 425b2 dbisam odbc std version using Vb6 > > I can retrieve data from the database but have a problem updating or inserting a new record > > --------------------------------------------------------------------------------- > > > Private RS As Recordset > Private DB As Database > Private WS As Workspace > > > Public Sub UpdateNote(Symbol As String) > > Caption = "User notes - " & Symbol > > Set WS = CreateWorkspace("", "", "", dbUseODBC) > Set DB = WS.OpenDatabase("Database", False, True, "ODBC;dsn=Smart > Charts;TablePassword1=Pass;") > Set RS = DB.OpenRecordset("SELECT * FROM UserNotes WHERE sName = '" & Symbol & "'", > dbOpenDynaset, dbExecDirect, dbOptimisticValue) > > 'This works perfect and I add the data to a text box > If RS.RecordCount <> 0 Then > txtNotes.Text = RS("sNote") > End If > > 'This below does nada nothing at all > > With RS > .Edit > .Fields(0) = "New" > .Fields(1) = "Record" > .Fields(2) = "BLA BLA BLA" > .Update > End With > > End Sub > > > Ta > |

Deneys | Hi Chris Holland
Thanks for your input I can now insert a new record and update that record as well, using the INSERT TO and UPDATE SQL statements this all works fine But..... I'm trying to update a memo field and if the input has a new line break for example it is a users notes then I get an error -------------------------------------------------------------------------- Chris Holland <mail@chrisholland.me.uk> wrote: The RS RecordSet is a "SELECT" statement.

Chris Holland SEC Solutions Ltd. ![]() | Hi Deneys,
I would recommend that you do the UPDATE and INSERT using parameters: Here is an example in C# MyCommand.SQL = "INSERT INTO MyTable (Title,Group,Description) VALUES (?,?,?)"; MyCommand.Parameters.Clear(); MyCommand.Parameters.Add("Title", OdbcType.VarChar, 50); // 50 char string length MyCommand.Parameters.Add("Description", OdbcType.Text); // Memo field MyCommand.Parameters["Title"].Value = "MyTitle"; MyCommand.Parameters["Description"].Value = Description.Text; // Data from memo edit MyCommand.ExecuteNonQuery(); Hope this helps Chris Holland Deneys wrote: > Hi Chris Holland > > Thanks for your input I can now insert a new record and update that record as well, using the > INSERT TO and UPDATE SQL statements this all works fine But..... > > > I'm trying to update a memo field and if the input has a new line break for example it > is a users notes then I get an error > > > > > > -------------------------------------------------------------------------- > > Chris Holland <mail@chrisholland.me.uk> wrote: > > The RS RecordSet is a "SELECT" statement. > To change the data in the table you will need to use either an "INSERT" or and "UPDATE" > command. > > As this code is in Visual Basic, something that I know nothing about I cannot give you an > example. > If you search the internet you should find plenty of examples of how to change data in VB > using ODBC drivers > > Chris Holland > > > Deneys wrote: >> Hi to all >> >> Please could some one help ? >> >> I have the 425b2 dbisam odbc std version using Vb6 >> >> I can retrieve data from the database but have a problem updating or inserting a new record >> >> --------------------------------------------------------------------------------- >> >> >> Private RS As Recordset >> Private DB As Database >> Private WS As Workspace >> >> >> Public Sub UpdateNote(Symbol As String) >> >> Caption = "User notes - " & Symbol >> >> Set WS = CreateWorkspace("", "", "", dbUseODBC) >> Set DB = WS.OpenDatabase("Database", False, True, "ODBC;dsn=Smart >> Charts;TablePassword1=Pass;") >> Set RS = DB.OpenRecordset("SELECT * FROM UserNotes WHERE sName = '" & Symbol & "'", >> dbOpenDynaset, dbExecDirect, dbOptimisticValue) >> >> 'This works perfect and I add the data to a text box >> If RS.RecordCount <> 0 Then >> txtNotes.Text = RS("sNote") >> End If >> >> 'This below does nada nothing at all >> >> With RS >> .Edit >> .Fields(0) = "New" >> .Fields(1) = "Record" >> .Fields(2) = "BLA BLA BLA" >> .Update >> End With >> >> End Sub >> >> >> Ta >> > |
