爲什麼有試圖從SQL表中選擇時錯誤

我在C＃下面的代碼來檢索表中的列：爲什麼有試圖從SQL表中選擇時錯誤

protected void Page_Load(object sender, EventArgs e) 
    { 

using (OleDbConnection connection = new OleDbConnection("Provider=MSDataShape;Data Provider=SQLOLEDB;" + 
    "Data Source=wmg-erp-db;Initial Catalog=DP;User ID=zh;Password=zhas")) 
{ 
OleDbDataAdapter adapter = new OleDbDataAdapter("SHAPE {SELECT FROM [DP].[dbo].[BT]} ", connection); 

DataSet customers = new DataSet(); 
adapter.Fill(customers, "Customers"); 
} 
    }

我收到以下錯誤：

Exception Details: System.Data.OleDb.OleDbException: Incorrect syntax near the keyword 'FROM'. 

Source Error: 


Line 35: 
Line 36: DataSet customers = new DataSet(); 
Line 37: adapter.Fill(customers, "Customers"); 
Line 38: } 
Line 39: } 


Source File: c:\Webserver\WEXEC\Booking\booking.aspx.cs Line: 37

如何我可以解決這個問題嗎？

你忘了你的'SELECT'部分後指定列。像'SHAPE * {SELECT FROM [DP]。[dbo]。[BT]}' –

DUH !!!我完全忽略了那一個。謝謝。 – SearchForKnowledge

您錯過了在查詢語句中提及字段/列名稱。無論是在您的查詢提一些具體列名（OR）*這裏

new OleDbDataAdapter("SHAPE {SELECT FROM [DP].[dbo].[BT]} "

線應該是

new OleDbDataAdapter("SHAPE {SELECT somecolumn FROM [DP].[dbo].[BT]} "

您需要指定要選擇的內容。正確的查詢將是 SELECT * FROM [DP].[dbo].[BT] 該查詢將返回所有記錄。

完全忽略。謝謝：） – SearchForKnowledge

SELECT * FROM，*失蹤。

要麼指定列名，或*所有列
