我正在尝试编写动态 SQL 查询 - 尝试在参数中传递列名。我面临的问题是，当我尝试Convert在字符串参数中传递 SQL 函数时，SQL Server 会引发语法错误。没有函数，Query 执行得非常好。错误是：

Msg 102, Level 15, State 1, Line 1
Incorrect syntax near '.'.

没有点“。” 我可以在我的查询中看到。但是，是的，作为参数传递给的数值Convert是浮点值。有人可以告诉我我做错了什么吗？

非常感谢。

declare

@orderBy nvarchar(200),
@sortOrder nvarchar(40), 
@fieldlist nvarchar(max),
@STMT nvarchar(max)

set @orderBy = 'Symbol'
set @sortOrder = 'Asc'
SET @fieldlist = 'Symbol, [Net Qty], [Total BUY], [Avg. BUY RATE], [Trans. Amount], [MTM Price], [MTM Amount], [Total SELL], [Avg. SELL RATE], [PENDING BUY], [PENDING SELL],  Convert(numeric(10,2),[SETTLED P/L]) as [SETTLED P/L],
 Convert(numeric(10,2),[UNSETTLED P/L]) as [UNSETTLED P/L] '


SET @STMT =  'SELECT  ' + @fieldlist + 
                  'FROM    (
                            SELECT  ROW_NUMBER() OVER(ORDER BY ' + @orderBy + ' '+@sortOrder+' '+') AS row, *
                            FROM    ' + '[Cats(Main)].[dbo].SESSION_HOLDING' + '
                            WHERE   ' + 'AccountNo = '''+'00'+'''' + '
                          ) AS tbl
WHERE
                          row > ' + CONVERT(varchar(9), @lbound) + ' AND
                          row < ' + CONVERT(varchar(9), @ubound)'
