用unified 跟SQL Server连接，语句是unified自带的，改了一下连接的语句，但是一直连不通，用traceviewer 抓到的信息，没有什么意义：下面是编写的语句，放在一个按钮触发：

export function 按钮_6_OnTapped(item, x, y, modifiers, trigger) {

(async function() {

 try{

  HMIRuntime.Trace("1");

  //let connectionstring = "data source=SK-20200905CGAE\SQLEXPRESS;initial catalog=test;integrated security=sspi;";

  //let connectionstring = "Driver=ODBC Driver 11 for SQL Server; Server=localhost; Database=test;trusted_connection=yes;";

//let connectionstring1 = "Driver={sql server};server=SK-20200905CGAE\SQLEXPRESS;database=test;uid=sa;pwd=123456;" ;

 let connectionstring = "Driver={SQL Server}; Server=SK-20200905CGAE\SQLEXPRESS; Database=test;uid=sa;pwd=123456;";

  HMIRuntime.Trace("2");

  let conn = await HMIRuntime.Database.CreateConnection(connectionstring);

  HMIRuntime.Trace("333");

  let query = "Select * from test;";

  let results = await conn.Execute(query);

  HMIRuntime.Trace("4");

   if(results !== undefined && results !== null)

  {

    let statements = results.Results;

    for(let statement in statements)

    {

      let rows = statements[statement].Rows;

      for (let i in rows)

      {

        let row = rows[i];

        for(let key in row)

        {

           HMIRuntime.Trace(key+":"+row[key]);

        }

      }

    }

  }

  conn.Close();

}

catch(e)

{

  let res = e.Results;

  for(let statement in res)

  {

    let errors = res[statement].Errors;

    for (let i in errors)

      {

        let detailed = errors[i];

        HMIRuntime.Trace("Errors state : "+detailed.State);

        HMIRuntime.Trace("Errors Message : "+detailed.Message);

      }

    }

  }

})();

}

下面是抓到的信息

数据库的服务器名称，数据库，用户名，密码用sql server management studio测试过是没问题的

哪位大神做过的，请指教一下
