I have a variable list of IDs. I want to update the "Status" column for each of those IDs in an Oracle database. I've searched and have come across the following options:

  • OracleDataAdapte开发者_开发百科r - Don't have a DataTable, only IDs
  • for loop which contains UPDATE statement (could be thousands of UPDATEs)
  • Stored Procedure - Hoping not to have to do this

Any help would be greatly appreciated. Thanks


If you already know the Ids you can build an in clause and do an ExecuteScalar:

update sometable set status = 'Shipped' where sometableid in (10,17,19,20,89)

It talks about using parameter arrays which may be perfect for what you are trying to do.


Thanksk for the replies. I had in mind to do it like the following, I was just concerned with keeping the connection open for so many iterations.

using (OracleConnection oracleConnection = new OracleConnection(connection))
                {
                    oracleConnection.Open();

                    OracleCommand Command = new OracleCommand();
                    Command.Connection = oracleConnection;
                    Command.CommandType = CommandType.Text;
                    status = "A";
                    foreach (var memberID in MemberIDs)
                    {
                        sqlStatement = " UPDATE " + " ourdbtable" + " Set userstatus = '" + status + "' WHERE " + "memberid= " + memberID;
                        // command
                        Command.CommandText = sqlStatement;
                        Command.ExecuteNonQuery();
                    }
                }
