OLEDB方式操作oracle資料庫

一.查詢語句：

using (OleDbConnection conn = new OleDbConnection(System.Configuration.ConfigurationManager.ConnectionStrings["local_Orcl"].ConnectionString))            {                conn.Open();                using (OleDbCommand cmd = conn.CreateCommand())                {                    try                    {                        cmd.CommandText = "select * from HLB_HIS_REQUISITION";                        DataTable dt = null;                        OleDbDataAdapter adapter = new OleDbDataAdapter();                        adapter.SelectCommand = cmd;                        dt = new DataTable();                        adapter.Fill(dt);                        cmd.Parameters.Clear();                        dataGridView1.DataSource = dt;                    }                    catch (Exception ee)                    {                        MessageBox.Show(ee.Message.ToString() + "\r\n" + ee.StackTrace.ToString());                        cmd.Dispose();                        conn.Close();                        conn.Dispose();                    }                }            }

 

二.插入語句：

 using (OleDbConnection conn = new OleDbConnection(System.Configuration.ConfigurationManager.ConnectionStrings["local_Orcl"].ConnectionString))            {                conn.Open();                using (OleDbCommand 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(1,‘張三‘, 1, 1, 1, 1, 1, 1)";                        cmd.ExecuteNonQuery();                    }                    catch (Exception ee)                    {                        MessageBox.Show(ee.Message.ToString() + "\r\n" + ee.StackTrace.ToString());                        cmd.Dispose();                        conn.Close();                        conn.Dispose();                    }                }            }

 

三.連接字串：

 <add name="local_Orcl" connectionString="Provider=OraOLEDB.Oracle.1;Data Source=(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=192.168.31.11)(PORT=1521))(CONNECT_DATA=(SERVICE_NAME=ORCL)));User ID=scott;Password=123;Unicode=True"/>

四.是否亂碼：

 

五.是否安裝用戶端：
