  • sql server连接字符串与tcp/ip开启

    连接字符串1:Data Source=localhost,1433;User ID=sa;Password=123;Initial Catalog=test;Min Pool Size=1;Max Pool Size = 512;

    连接字符串2:Data Source=localhost;User ID=sa;Password=123;Initial Catalog=test;

    SQL SERVER数据库中的TCP/IP如果没有开启,只能用第二句连接字符串,开启都可用。字符串1是通过走网络的。

    如果你应用了第一句字符串,必须在SQL server配置器中开启tcp/ip,然后重启sql server服务。就OK

    否则报错
