--------------------编程问答-------------------- 什么问题
--------------------编程问答-------------------- SqlConnection myConnection = New SqlConnection(@"server=PC-201101031142\SQLEXPRESS;uid=sa;pwd=aaa;database=test"); --------------------编程问答-------------------- 这段代码提示错误。 SqlConnection myConnection = New SqlConnection("server=PC-201101031142\SQLEXPRESS;uid=sa;pwd=aaa;database=test");
--------------------编程问答-------------------- 谢谢二楼的朋友，我按照你的改了一下，还是提示这行有错误。 --------------------编程问答-------------------- Data Source=myServerAddress;Initial Catalog=myDataBase;User Id=myUsername;Password=myPassword;
connectionString = "Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\NORTHWND.MDF;Integrated Security=True;Connect Timeout=30;User Instance=True;Provider=SQLOLEDB"
详细信息 --------------------编程问答--------------------
兄弟，帮人帮到底，我是初学者，有些地方看的不太明白。能不能按照我的程序再结合你的这段代码，帮我写一下正确的，给您添麻烦了。 --------------------编程问答--------------------
string con= "Data Source=.\\SQLEXPRESS;AttachDbFilename=|DataDirectory|\\test.mdf;uid=sa;pwd=aaa;";
SqlConnection conn = new SqlConnection(con);

谢谢楼上的朋友，改成这样了，又提示 SqlCommand myCommand = New SqlCommand( "select * from [testtable]", con );
这行有错误。朋友们，再帮忙看看吧。谢谢了。 --------------------编程问答-------------------- 顶一下，再线等。 --------------------编程问答-------------------- 等什么
初学者 ADO.net的东西学好了再操作数据库
否则就先把 HTML 练熟 --------------------编程问答--------------------
