ADO.Net对oracle数据库操作的实例代码


            首先要写连接字符串

可以在web.config里写上

复制代码 代码如下:<connectionStrings>     <add name="oracleson" connectionString="Data Source=dingsenorcl;Persist Security Info=True;User ID=ds;Password=ds;Unicode=True" providerName="System.Data.OracleClient"/>   </connectionStrings> 

<connectionStrings>    <add name="oracleson" connectionString="Data Source=dingsenorcl;Persist Security Info=True;User ID=ds;Password=ds;Unicode=True" providerName="System.Data.OracleClient"/>  </connectionStrings>然后再后台调用复制代码 代码如下:string orclcon = ConfigurationManager.ConnectionStrings["oracleson"].ConnectionString; 

  string orclcon = ConfigurationManager.ConnectionStrings["oracleson"].ConnectionString;然后要新建一个数据库连接对象

复制代码 代码如下:OracleConnection conn = new OracleConnection(orclcon) 

OracleConnection conn = new OracleConnection(orclcon)创建一个OracleCommand对象来对数据库进行操作复制代码 代码如下:OracleCommand cmd = conn.CreateCommand() 

OracleCommand cmd = conn.CreateCommand()打开连接

conn.Open();操作就行了

复制代码 代码如下:cmd.CommandText = "insert into T_12(AAAA)values(:a)";                     cmd.Parameters.AddWithValue(":a", TextBox1.Text);  //参数替换oracle数据库要用: sqlserver数据库是@                     cmd.ExecuteNonQuery(); 

cmd.CommandText = "insert into T_12(AAAA)values(:a)";                    cmd.Parameters.AddWithValue(":a", TextBox1.Text);  //参数替换oracle数据库要用: sqlserver数据库是@                    cmd.ExecuteNonQuery();
