ODBC方式操作oracle数据库

ODBC方式操作oracle数据库

一.查询语句：

 var strConn = System.Configuration.ConfigurationManager.ConnectionStrings["local_Orcl"].ConnectionString;
            using (OdbcConnection odbcconn = new OdbcConnection(strConn))
            {
                odbcconn.Open();
                string strComm = "select * from HLB_HIS_REQUISITION";
                OdbcDataAdapter odbcda = new OdbcDataAdapter(strComm, odbcconn);
                DataSet ds = new DataSet();
                odbcda.Fill(ds);
                DataTable dt = new DataTable();
                dt = ds.Tables[0];
                odbcconn.Close();
                odbcconn.Dispose();
                dataGridView1.DataSource = dt;
            }

二.插入语句：

using (OdbcConnection conn = new OdbcConnection(System.Configuration.ConfigurationManager.ConnectionStrings["local_Orcl"].ConnectionString))
            {
                conn.Open();
                using (OdbcCommand cmd = conn.CreateCommand())
                {
                    try
                    {
                        cmd.CommandText = "insert into hlb_his_requisition(requisition_id, patient_name, patient_sex, patient_age, patient_bed, charge_name, sample_class, requisition_state)values(3,'王五', 1, 1, 1, 1, 1, 1)";
                        cmd.ExecuteNonQuery();
                    }
                    catch (Exception ee)
                    {
                        MessageBox.Show(ee.Message.ToString() + "
" + ee.StackTrace.ToString());
                        cmd.Dispose();
                        conn.Close();
                        conn.Dispose();
                    }
                }
            }

三.连接字符串：

<add name="local_Orcl" connectionString="provider=MSDAORA.1;Dsn=zlpTest;uid=scott;pwd=123;database=orcl"/>

四.是否乱码：

五.是否需要安装客户端：
