我尝试将GroceryCRUD与SQL Server（2008 R2）一起使用来管理一些表。
好吧，我发现以下线程在StackOverflow上非常有用： How can I run grocery with sql server?
但是，当我使用$this->grocery_crud->set_relation时，它会返回错误＆＃34;未找到PrimaryKey＆＃34;在方法set_primary_key上。
该表显然已正确设置主键。
有人可以帮我找出问题所在吗？

确定。这就是我破解代码的方式：
ref.version：
第1步
档案： driver = new FirefoxDriver();
string baseurl = "http://localhost:53532";
String ourPath = "~/visual studio 2015";
String testTitle = ourPath + "test.txt";
String testScreenshotTitle = ourPath + "test.jpg";
driver.Navigate().GoToUrl(baseurl);
ITakesScreenshot screenshotDriver = driver as ITakesScreenshot;
Screenshot screenCapture = screenshotDriver.GetScreenshot();
screenCapture.SaveAsFile(testScreenshotTitle, System.Drawing.Imaging.ImageFormat.Jpeg);
更新方法 field_data（$ table）

档案：public function field_data($table)

更新方法 field_data（）
\system\database\drivers\mssql\mssql_result.php这就是全部。我希望它可以帮助其他人。
