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();
