SQL Server CE executes the same prepared statement no matter what

Question

I'm trying to insert some data read from XML files into my database. The problem is that it only executes one prepared statement (the first one i defined) and this causes errors.

This works:

conn = getConnection();
conn.Open();

SqlCeCommand cmd = conn.CreateCommand();
cmd.CommandText = "INSERT INTO ra_gestiuni ([denumire],[id_ra]) Values(@denumire,@id_ra)";

SqlCeParameter numeParam = new SqlCeParameter("@denumire", SqlDbType.NVarChar, 100);
numeParam.Value = denumire;
cmd.Parameters.Add(numeParam);

SqlCeParameter idRAParam = new SqlCeParameter("@id_ra", SqlDbType.Int);
idRAParam.Value = idRA;
cmd.Parameters.Add(idRAParam);

cmd.Prepare();
cmd.ExecuteNonQuery();
cmd.Dispose();
conn.Close();

This does not work anymore:

conn = getConnection();
conn.Open();

SqlCeCommand cmd = conn.CreateCommand();

cmd.CommandText = "INSERT INTO ra_active ([denumire],[gestiune],[utilizator],[tip_activ],[nr_invetar],[categorie_activ],[patrimoniu],[id_ra]) Values(@denumire,@gestiune,@utilizator,@tip_activ,@nr_invetar,@categorie_activ,@patrimoniu,@id_ra)";

SqlCeParameter numeParam = new SqlCeParameter("@denumire", SqlDbType.NVarChar, 100);
numeParam.Value = denumire;
cmd.Parameters.Add(numeParam);

SqlCeParameter gestiuneParam = new SqlCeParameter("@gestiune", SqlDbType.Int);
gestiuneParam.Value = gestiune;
cmd.Parameters.Add(gestiuneParam);

SqlCeParameter utilizatorParam = new SqlCeParameter("@utilizator", SqlDbType.Int);
utilizatorParam.Value = utilizator;
cmd.Parameters.Add(utilizatorParam);

SqlCeParameter nrInventarParam = new SqlCeParameter("@nr_inventar", SqlDbType.NVarChar);
nrInventarParam.Value = nrInventar;
cmd.Parameters.Add(nrInventarParam);

SqlCeParameter categorieActivParam = new SqlCeParameter("@categorie_activ", SqlDbType.NVarChar);
categorieActivParam.Value = categorieActiv;
cmd.Parameters.Add(categorieActivParam);

SqlCeParameter patrimoniuParam = new SqlCeParameter("@patrimoniu", SqlDbType.Int);
patrimoniuParam.Value = patrimoniu;
cmd.Parameters.Add(patrimoniuParam);

SqlCeParameter tipActivParam = new SqlCeParameter("@tip_activ", SqlDbType.Int);
tipActivParam.Value = tipActiv;
cmd.Parameters.Add(tipActivParam);

SqlCeParameter idRAParam = new SqlCeParameter("@id_ra", SqlDbType.Int);
idRAParam.Value = idRA;
cmd.Parameters.Add(idRAParam);

cmd.Prepare();
cmd.ExecuteNonQuery();
cmd.Dispose();
conn.Close();

I get this exception:

The column name is not valid [ Node name (if any) = ,Column name = gestiune ]

This happens because it tries to insert in the previous table (from the previous prepared statement). This is insane, I haven't found any solution to this.

Answer 1

What I see is the parameter @nr_inventar does not exists in your command text (you have @nr_invetar there). Also if you really need to prepare the command before executing, you should set a size for all nvarchar parameters, like you did for @denumire.
