Когда я использовал:` 

EXECUTE SP_EXECUTESQL @SQL, 
        N'@UtilityID varchar(6)',       -- this is an argument #1 with 1 parameter
        N'@SearchText VARCHAR(MAX)',    -- this is an argument #2 with 1 parameter
                                        -- that's why we get an error saying too 
                                        -- many arguments
        @UtilityID = @UtilityID,
        @SearchText = @SearchText

`
`
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
