SQL Server 2005：幫助連接Nvarchar和Int

Question

由於我在Nvarchar內部使用了Int變量，因此我有這段代碼出錯。如果我使用

CAST(CAST(COALESCE(@FattAnnoCorrente) as int) as varchar(255)) 

我，而不是讓這些錯誤

Conversion failed when converting the nvarchar value 'ANNO 2016 -' to data type int.

：

Msg 102, Level 15, State 1, Line 154
Incorrect syntax near ')'.
Msg 156, Level 15, State 1, Line 173
Incorrect syntax near the keyword 'FOR'.

你能幫我解決這個問題

DECLARE @FattAnnoCorrente INT; 
DECLARE @Tabscontianno1 NVARCHAR(MAX); 

SET @Tabscontianno1 = 
N'<p align="left"><b>ANNO ' + @Anno1 + ' - </b><b>' + @FattAnnoCorrente + '<br> 
    </b></p> 
<table height="62" border="1" cellpadding="2" cellspacing="2" 
    width="501"> 
    <tbody> 
    <tr> 
     <td valign="top">FATTURATO<br> 
     </td> 
     <td valign="top">SCONTO<br> 
     </td> 
    </tr>' + CAST ((
        SELECT 
        td = SUM(TOTNETTORIGA), '', 
        td = SCONTIESTESI 
        FROM .dbo.TESTEDOCUMENTI 
        INNER JOIN .dbo.RIGHEDOCUMENTI 
        ON PROGRESSIVO=IDTESTA AND TOTNETTORIGA <>'0' 
        WHERE CODCLIFOR = @CodiceCliente AND .dbo.TESTEDOCUMENTI.DOCCHIUSO = '0' AND .dbo.TESTEDOCUMENTI.BLOCCATO = '0' AND .dbo.TESTEDOCUMENTI.TIPODOC = 'FVC' AND .dbo.TESTEDOCUMENTI.ESERCIZIO = YEAR(GETDATE()) 
        GROUP BY TESTEDOCUMENTI.ESERCIZIO,SCONTIESTESI 
    FOR XML PATH('tr'), TYPE) 
    AS NVARCHAR(MAX)) + 
    N' </tbody> 
</table>'+ 
    N'<BR/>' ; 

我得到這個錯誤。

插入後，它在nvarchar可變我需要把它格式化爲錢這樣的：

'€ ' + REPLACE(CONVERT(varchar, CAST(@FattAnnoCorrente AS money), 105),',','.') 

謝謝你們！

你需要轉換所有INT類型VARCHAR ..

你的情況，你是第一投射他們INT ..下面的語句

變化

CAST(CAST(COALESCE(@FattAnnoCorrente) as int) as varchar(255)) 

到

cast(COALESCE(@FattAnnoCorrente,'somevalue') as varchar(255))
