Sql server 注释行出错

您好，我已经创建了一个存储过程，该存储过程链接到一个具有三个外键的表地址：

-材料地址 -HomeAddressID -后腹腔镜

这是我创建的存储过程：

-- =============================================
-- Author:  *******************
-- Create date: 11.07.2013
-- Description: Gets User Personal Details
-- =============================================
    ALTER PROCEDURE [eConnect].[GetUserPersonalDetails]
        @personId int
    AS
    BEGIN
        SELECT Persons.PersonalID,
               Persons.FirstName ,
               Persons.MiddleName , 
               Persons.LastName ,
               Persons.DateOfBirth,
               Persons.CityOfBirth ,
               Persons.BSN ,
               Persons.SecondaryEmail ,
               Persons.HomePhone ,
               Persons.WorkPhone ,
               Persons.MobilePhone,
               MaterialAddress.StreetName ,
               MaterialAddress.PostCode ,
               MaterialAddress.City ,
               HomeAddress.StreetName ,
               HomeAddress.PostCode ,
               HomeAddress.City ,
               PostalAddress.StreetName ,
               PostalAddress.PostCode ,
               PostalAddress.City
        FROM Sync_Persons as Persons
        JOIN Sync_Addresses as MaterialAddress ON Persons.MaterialAddressID = MaterialAddress.AddressID
        JOIN Sync_Addresses as HomeAddress ON Persons.HomeAddressID = HomeAddress.AddressID
        JOIN Sync_Addresses as PostalAddress ON Persons.PostalAddressId = PostalAddress.AddressID
        WHERE Persons.PersonalID = @personId
    END

当我尝试执行此操作时，会出现以下错误：

Msg 245，16级，状态1，过程GetUserPersonalDetails，第11行将varchar值“I-024800”转换为时失败 数据类型int

本例中的第11行是：--Description:获取用户个人详细信息

---

为什么我在评论中出现错误？我如何更正它？

尝试更改这一行-

WHERE CAST(SUBSTRING(
     Persons.PersonalID, 
     CHARINDEX('-', Persons.PersonalID) + 1, 
     LEN(Persons.PersonalID)
) AS INT) = @personId

或者试试这个-

WHERE Persons.PersonalID = 'I-' + CAST(@personId AS VARCHAR(10))

---

看起来Persons中的PersonalID列可能是某个序列或身份的计算列。因为@personId已经是一个int，这意味着PeronalID是'I-024800'的值，所以添加'I-'将不起任何作用。如果正确的表达式应该更改为'I-'+CAST（@personId AS varchar（10））是的，这很好，但我仍然认为更改正确的表达式会更好，因为左侧保留搜索表达式。现在，您强制它比较必须首先通过强制转换获得的非索引值。
