Vb.Net SQlConnection 字符串之间的区别

Question

大家好，我有一个简单的问题，关于这些 SQlConnection 字符串之间的区别

1.

Dim Con As New SqlConnection("Server = Z\SQL; Database = Project; id = zzz; pwd = zzz integrated Security = true")

Dim Con As New SqlConnection("Driver = {SQL SERVER}; Server = Z\SQL; Database = Project; id = zzz; pwd = zzz integrated Security = true")

    Dim Con As New SqlConnection("@Server = Z\SQL; Database = Project; id = zzz; pwd = zzz integrated Security = true")

还有哪个是最优化的程序？

先致谢

Answer 1

1 和 2 代码相同，如果您不想通过 Windows 身份验证访问您的 SQL，则将集成安全设置为 False，然后添加 UID（Sql Login Id) & PWD (Password) 到字符串中。

谢谢大家。
