Question

请帮我解决此更新查询。我完全理解这是多余的，但我需要它。当用户创建一个仅包含ID，用户名，密码和客户ID的用户帐户时，我必须在客户创建自己的记录中创建一条记录，但是所有内容都为null，而User.User_Customer_ID必须更新为新创建的Customer.Customer_ID

我有一切正常但这个讨厌的更新查询。它需要做的唯一事情就是将User.User_Customer_ID更改为Customer.Customer_ID我设法将User.User_ID更改为一个名为UserID的整数，而Customer.Customer_ID就是一个名为CustomerID的整数，我尝试了一百万种不同的方法但没有成功

以下是我尝试过的众多查询之一。

1. UPDATE [User]
   SET User_Customer_ID = Customer.Customer_ID
   FROM Customer
   WHERE [User].User_ID = '16'
   AND Customer.CUstomer_ID = '19'
  ( ? would be the integer UserID and CustomerID )

以下是它在插入VB

中的SQL命令之前的样子

   UpdateUserCustomerID = "UPDATE [User] SET User_Customer_ID = Customer.Customer_ID FROM Customer WHERE ([User].User_ID ='" & UserID & "' AND Customer.Customer_ID = '" & CustomerID & "')"

Access Database / ASP.Net / VB

Table:

Customer:

Customer_ID
Customer_First_Name
Customer_Last_Name
Customer_Street_Address
Customer_City
Customer_State
Customer_Zip
Customer_Email

User:

User_ID
User_UserName
User_Password
User_Customer_ID

Answer 1

我似乎不太可能ID是文本字段（列），如果它们是数字字段，则引号是问题之一。

据我所知，这是：

"UPDATE [User] SET User_Customer_ID = Customer.Customer_ID FROM Customer WHERE ([User].User_ID ='" & UserID & "' AND Customer.Customer_ID = '" & CustomerID & "')"

应该是：

"UPDATE [User] SET User_Customer_ID = " & CustomerID _
& " WHERE ([User].User_ID = " & UserID

使用两个表asp.net vb更新查询
