问题

你们的大学课程正在进行一个项目，之前已经建立了多次而没有错误。然而，最近的一些更改导致了这个错误的发生：

我并不确定问题出在哪里。以下是我们的连接字符串：

"ConnectionStrings": {
	"DefaultConnectionString": "server=localhost;User Id=root;password=password;database=ourproject;",
	"DefaultConnectionString_Select": "server=localhost;User Id=root;password=password;database=ourproject_application;",
	"SqliteMain": "Data Source=main.db",
	"SqliteProvider": "Data Source=provider.db",
	"OurprojectDB": "Data Source=SQL8005.site4now.net;Initial Catalog=db_a96e9a_ourproject001;User Id=db_a96e9a_ourproject001_admin;Password=mihighschool"
}

有人知道可能出了什么问题吗？

I don't really know where the issue is. Here's our connection strings:

&quot;ConnectionStrings&quot;: {
	&quot;DefaultConnectionString&quot;: &quot;server=localhost;User Id=root;password=password;database=ourproject;&quot;,
	&quot;DefaultConnectionString_Select&quot;: &quot;server=localhost;User Id=root;password=password;database=ourproject_application;&quot;,
	&quot;SqliteMain&quot;: &quot;Data Source=main.db&quot;,
	&quot;SqliteProvider&quot;: &quot;Data Source=provider.db&quot;,
	&quot;OurprojectDB&quot;: &quot;Data Source=SQL8005.site4now.net;Initial Catalog=db_a96e9a_ourproject001;User Id=db_a96e9a_ourproject001_admin;Password=mihighschool&quot;
}

Does anyone have an idea what might have gone wrong?

得分: 1

根据引用文件SQLite连接字符串

您必须使用Data Source而不是Server。

英文:

According to referenced document SQLite Connection strings

you have to use Data Source instead of Server.

答案2

得分: 0

如果您正在尝试连接到 SQL Server，请将 Server 替换为 Data Source。

英文:

If you're trying to connect to SQL Server, then replace Server with Data Source
