错误如下:“Parameter name is unrecognized.”。失败的原因可能有:

SELECT Id, AnimalName FROM dbo.Farm WHERE Farm_id = ?

Assuming my Parameter is an integer Variable named User::Farm_id Choose the following values on the Parameter Mapping Screen

Variable Name  -   User::Farm_id
Direction      -   Input
Data Type      -   LONG
Parameter Name -   0
Parameter Size -   -1
