ADO.Net对oracle数据库的操作

首先要写连接字符串

可以在web.config里写上

[html]
<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

[html]
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

[html]
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

[html]
OracleCommand cmd = conn.CreateCommand() 

OracleCommand cmd = conn.CreateCommand()打开连接

[html] view plaincopyprint?conn.Open(); 

conn.Open();操作就行了

[html]
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();
