SSIS：通过表达式向SQL查询添加int变量

我在SSIS中添加了一个变量，我正在尝试在表达式查询中添加该变量。但是它说，

表达式不能计算

下面是我的表达式查询。如果你知道我在哪里犯错，请帮我

SQL查询

SELECT c.CustomerName, o.OrderID from  Customers c
INNER JOIN Orders o ON c.CustomerID=o.CustomerID
Inner Join OrderDetails od ON od.OrderId = o.OrderID
Inner Join Products p on p.ProductID = od.ProductID 
where ISNULL(c.IsResult,0) = 0 and o.CompanyID = @CompanyID

表达式格式

"SELECT c.CustomerName, o.OrderID from  Customers c
    INNER JOIN Orders o ON c.CustomerID=o.CustomerID
    Inner Join OrderDetails od ON od.OrderId = o.OrderID
    Inner Join Products p on p.ProductID = od.ProductID 
    where ISNULL(c.IsResult,0) = 0 and o.CompanyID ="+ @[User::intCompanyID]

让我知道我是否做对了。

您是否尝试过以下方法

"SELECT c.CustomerName, o.OrderID from  Customers c
INNER JOIN Orders o ON c.CustomerID=o.CustomerID
Inner Join OrderDetails od ON od.OrderId = o.OrderID
Inner Join Products p on p.ProductID = od.ProductID 
where ISNULL(c.IsResult,0) = 0 and o.CompanyID = ?"

单击“参数”按钮，然后可以从中选择参数

希望这能有所帮助。

我发现将数值转换为字符串或Unicode是可行的。所以也许可以试试

ISNULL（c.IsResult，0）=0和o.CompanyID=“+（DT_WSTR，20）@[User:：intCompanyID]
