Sql server 我得到一个错误，说Msg 137，级别15，状态2，第8行必须声明标量变量@实用ID“；

`

当我使用： `

---

看第64行。动态sql字符串中包含@UtilityID。但您不会将该参数传递给动态sql。老实说，这东西看起来需要大修。到处都是动态sql，这表明设计有问题。我认为这里不需要任何动态sql。谢谢！我能修好那部分。我已经有一段时间没有这样做了，我可能需要做更多的阅读。现在，我得到的过程或函数必须指定许多参数。为什么要为此使用动态sql？这看起来只不过是一个带有几个where谓词的查询。

I get the message saying:

Msg 137, Level 15, State 2, Line 8
Must declare the scalar variable "@UtilityID".
Msg 8144, Level 16, State 2, Line 2
Procedure or function  has too many arguments specified.



It took me awhile to figure out but this is the correct syntax:
`
`
`
EXECUTE SP_EXECUTESQL @SQL, 
        N'@UtilityID varchar(6), 
          @SearchText VARCHAR(MAX)', 
`

          @UtilityID = @UtilityID, 
          @SearchText = @SearchText
