如何从C＃运行'alter user'命令

Question

我有一个oracle数据库，每当用户帐户被锁定时，我都会运行命令

ALTER USER xxxxx ACCOUNT UNLOCK;

有没有办法从C＃应用程序执行此操作？

Answer 1

与其他数据库相同。您将在打开的数据库连接上创建IDbCommand，为其分配要触发的查询并执行它。

static void Main()
{
    string constr = //Connection string         
    DbProviderFactory factory = DbProviderFactories.GetFactory("Oracle.DataAccess.Client");     

    try
    {
      using(DbConnection conn = factory.CreateConnection())
      {
          conn.ConnectionString = constr;
          conn.Open(); 
          using(DbCommand cmd = conn.CreateCommand())
          {
             cmd.CommandText = "ALTER USER xxxxx ACCOUNT UNLOCK;"; 
             cmd.ExecuteNonQuery();
          }
      }
    }
    catch (Exception ex)
    {
      Console.WriteLine(ex.Message);
      Console.WriteLine(ex.StackTrace);
    }
}
