已链接 Table 显示为只读

Question

我正在使用 C# 创建一个 SQL 服务器视图，然后打开一个 access 数据库并 link table 进入 access。创建视图语句、打开数据库语句和 link 语句工作得很好但是这里的问题是它总是 link table 为只读.我需要添加或更新哪一段代码才能使视图不总是 link 编辑为只读？

string MasterDatabase = "R:\Testing\MasterDatabase.mdb";
DAO.Database dd;
DAO.DBEngine db = new DAO.DBEngine();
DAO.TableDef tdf9;
bool found = false;
DAO.TableDef tdf1;
string Table = "ServiceEntranceLog";
string TableAccess = "Service_Entrance_Log";

using (var connection = new SqlConnection(ConnectionStringHere))
using (var command = connection.CreateCommand())
{   
            using (var command4 = connection.CreateCommand())
            {
                            command4.CommandText = "CREATE VIEW HelperView" AS SELECT * FROM monster.ServiceEntranceLog";
                            command4.ExecuteNonQuery();
            }
}
if (_combobox1.SelectedItems.Contains("MasterDatabase"))
{
            dd = db.OpenDatabase(CRDB);
            try
            {
                            string[] tableNames = new string[1] { TableAccess };
                            for (int q = tableNames.GetLowerBound(0); q <= tableNames.GetUpperBound(0); q++)
                            {
                                            foreach (DAO.TableDef tabledef in dd.TableDefs)
                                            {
                                                            string name = tableNames[q];
                                                            if (tabledef.Name == name) { found = true; }
                                                            try { if (found) { dd.TableDefs.Delete(name); } }
                                                            catch { }
                                            }
                            }
            }
            catch { }
            tdf1 = dd.CreateTableDef(TableAccess);
            tdf1.Connect = connectionString;
            tdf1.SourceTableName = Table;
            dd.TableDefs.Append(tdf1);
}

Alritey，看来问题是我需要在 table 中链接到访问时定义主键，以便 table 可以更新。使用这种语法就可以了

dd.Execute "CREATE UNIQUE INDEX SomeIndex ON SomeTable (PrimaryKeyColumn) WITH PRIMARY"
