Question

当我运行以下代码＆＃34; ORA-01008时：并非所有变量都绑定了＃34;正在显示。 Wile调试我可以在这个语句中看到@Number的值 - ＆gt; ＆＃34; ParameterDirection.Input，@ NUMBER＆＃34; 。但正在显示执行错误。

     DB_Common _dbCommon = new DB_Common();
                DbConnection conn2 = _dataFactory.CreateConnection();
                DbCommand cmd1 = _dataFactory.CreateCommand();
                conn2.ConnectionString = ABC.AppSettings ["ORACnnStr_HOSPITAL"];
                conn2.Open();

        cmd1.Connection = conn2;
                cmd1.Transaction = trans;
                cmd1.CommandText = OracleHelper.FixCommandText("INSERT INTO NBTABLE(NUMBER) VALUES(@NUMBER) ");

   cmd1.CommandType = CommandType.Text;
                DbParameter param2 = null;
                foreach (DataRow dr2 in _DTF_SPE.Rows)
                {
                    cmd1.Parameters.Clear();

                    OracleHelper.CreateParameter(ref cmd, ref param, "@NUMBER", DbType.String, ParameterDirection.Input, @NUMBER);

                 cmd1.ExecuteNonQuery();
                    cmd1.Dispose();
    }
            }

            trans.Commit();
        }

修改

更新了如下代码。在开始使用conn2之前，@ doctor的值取自conn1.conn1。 ORA-01008：并非所有变量绑定都在执行时显示。

        DB_Common _dbCommon = new DB_Common();
            DbConnection conn2 = _dataFactory.CreateConnection();
            DbCommand cmd1 = _dataFactory.CreateCommand();
            conn2.ConnectionString = SCC.AppSettings["ORACnnStr_abc"];
            conn2.Open();
            cmd1.Connection = conn2;
            cmd1.Transaction = trans;
            cmd1.CommandText = OracleHelper.FixCommandText("INSERT INTO numbertable(Doctor,PART,CODE) VALUES(@doctor,'K','G') ");

            cmd1.CommandType = CommandType.Text;
            DbParameter param2 = null;

            cmd1.Parameters.Clear();
            cmd1.ExecuteNonQuery();
            cmd1.Dispose();

Answer 1

使用分号:格式代替@格式 "INSERT INTO NBTABLE(NUMBER) VALUES(:NUMBER_) "您最好提供NUMBER_（关键字）以外的名称（如NUMBER）。

再次致电@： OracleHelper.CreateParameter(ref cmd, ref param, "NUMBER_",....

insering时出错 - 并非所有变量都绑定
