(Sorry for my bad English)
What was happen with this problem?
Becose I'm using 1.7 Provider, and I have a problem that seems to be
related:
Unhandled Exception: System.NullReferenceException: Referencia a objeto
no establecida como instancia de un objeto.
at FirebirdSql.Data.Firebird.FbDataAdapter.Update(DataRow[]
dataRows, DataTableMapping tableMapping)
at System.Data.Common.DbDataAdapter.Update(DataTable dataTable)
at PF.WinForms.Usuario.Form1..ctor(MmConnection conexion)
at sigeme.ContextoAplicacion..ctor(Boolean loginAutomatico)
at sigeme.ContextoAplicacion.Main(String[] args)
And my code is this:
dataadapter.SelectCommand = new FbCommand("Select NOMBRE, TIPO, VALOR
from SPESTADOSARTICULO(@IdArticulo)",connection);
FbParameter parameterTmp =
dataadapter.SelectCommand.Parameters.Add("@IdArticulo", FbDbType.Integer);
parameterTmp.Value = 1118;
dataadapter.UpdateCommand = new
FbCommand("CAMBIARESTADOARTICULO",connection);
dataadapter.UpdateCommand.CommandType = CommandType.StoredProcedure;
dataadapter.UpdateCommand.Parameters.Add("@IdArticulo",
dataadapter.SelectCommand.Parameters["@IdArticulo"].Value);
parameterTmp = dataadapter.UpdateCommand.Parameters.Add("@NombreEstado",
FbDbType.VarChar, 20);
parameterTmp.SourceColumn = "NOMBRE";
parameterTmp.SourceVersion = DataRowVersion.Original;
parameterTmp =
dataadapter.UpdateCommand.Parameters.Add("@Valor",FbDbType.VarChar,20);
parameterTmp.SourceVersion = DataRowVersion.Current;
parameterTmp.SourceColumn = "VALOR";
dataadapter.Fill(datatable);
datatable.PrimaryKey = new DataColumn[] {datatable.Columns["NOMBRE"]};
datatable.Rows[0]["VALOR"] = "0";
dataadapter.Update(datatable);
Well, maybe my code is bad, please correct me.
Thanks, and sorry for my English again.
