Solved MySQL SELECT

I am trying to check the availability of records in the table. Querying the database is correct. But i can't write the code... I saw the Extensions.

Code:

void OnPlayerInit(BasePlayer player)
  {
  string name = player.displayName;
  string steamid = player.UserIDString;
  var sql = Sql.Builder.Append(SelectData, steamid);
  Puts("sql1");
  _mySql.Query(sql, _mySqlConnection, list =>
  {
  Puts("bif");
  foreach (var entry in list)
  {
  if (entry["steamid"] == steamid) return;
  Puts("sql2");
  sql = Sql.Builder.Append(InsertData, name, steamid, 0, 0, 0, 0, 0, 0, 0, 0);
  Puts("ins");
  _mySql.Insert(sql, _mySqlConnection);
  }
  });  }

Request:

Code:

private const string InsertData = "INSERT INTO `rank` (`name`, `steamid`, `pvpkill`, `resources`, `pvpdistans`, `kd`, `death`, `hellidestr`, `explosives`, `suicide`)" + " VALUES (@0, @1, @2, @3, @4, @5, @6, @7, @8, @9);";
        private const string SelectData = "SELECT * FROM `rank` WHERE steamid=@0";

I'm sorry for bad english.

 

Solved.
