关于SQL Server链接

Question

con为System.Data.SqlClient.SqlConnection对象
con.ConnectionString="user id=sa;password=;initial catalog=chb;Server=Local";
为什么连不上SQL Server 数据库
而改成将上面的Local改成计算机名就可以。

Answer 1

="user id=sa;password=;initial catalog=chb;Server=(local)"; 

Answer 2

"uid=sa;pwd=;database=chb;server=(local)"或"uid=sa;pwd=;database=chb;server=localhost"或"uid=sa;pwd=;database=chb;server=127.0.0.1"或"uid=sa;pwd=;database=chb;server=计算机名"

Answer 3

uid=sa;password=;initial catalog=chb;Server=.;
