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:
