MS-Access查詢語法

Question

我有mysql的背景。 現在，我正在使用C＃進行MS-Access。 我試過以下SQL查詢，但會引發異常

查詢1：

String strSql = "Select * from Employees orderby EmployeeID desc limit 1;";
OleDbDataAdapter adapter = new OleDbDataAdapter(strSql, conn);
adapter.Fill(dt);

String strSql = "Select * from Employees orderby EmployeeID asc limit 1;";
OleDbDataAdapter adapter = new OleDbDataAdapter(strSql, conn);
adapter.Fill(dt);

常見例外1：

Additional information: Syntax error in FROM clause.

查詢2：

String strSql = "select * from Employees where EmployeeID = (select min(EmployeeID) from Employees where EmployeeID < '" + Int64.Parse(this.txtBoxID.Text) + "');";
OleDbDataAdapter adapter = new OleDbDataAdapter(strSql, conn);
adapter.Fill(dt);

String strSql = "select * from Employees where EmployeeID = (select min(EmployeeID) from Employees where EmployeeID > '" + Int64.Parse(this.txtBoxID.Text) + "');";
OleDbDataAdapter adapter = new OleDbDataAdapter(strSql, conn);
adapter.Fill(dt);

常見例外2：

Additional information: Data type mismatch in criteria expression.

Answer 1

為什么不使用查詢設計器在訪問中創建查詢，更改為sql視圖，然后將sql復制回代碼中？

此外，我認為您必須具有訪問權限，

SELECT TOP 1 * from Employees;

而不是

Select * from Employees limit 1;

Answer 2

並查詢1：

Select * from Employees order by EmployeeID ...
