连接到 SQL Server 数据库时,如果实例名称不正确,会出现以下错误提示:
"Cannot connect to <ServerName>"
"A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)"
或者
"Cannot connect to <ServerName>\<InstanceName>"
"A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)"
在这两种情况下,错误信息中都会提示实例名称不正确。您需要检查实例名称是否正确,如果实例名称正确,还需要检查 SQL Server 是否已经启动,以及是否已经配置允许远程连接。
