爲什麼我得到的二進制或字符串數​​據將被截斷

Question

我有下面的查詢，其中我插入到臨時表中，當我嘗試運行查詢sql是拋出二進制或字符串數​​據將被截斷。但實際上，我的數據在列PhoneModel的定義nvarchar(400)的範圍內。

CREATE TABLE #orders 
(
    quoteHeaderId INT, 
    PhoneModel nvarchar(400) 
) 

INSERT INTO #orders(quoteHeaderId, PhoneModel) 
SELECT qh.QuoteHeaderId, 
    (Select ph.ModelName + ',' 
    FROM t_handsetQuote h2 
     INNER JOIN t_PhoneAudit t1 on t1.PhoneAuditId = h2.QuotePhoneAuditId 
     INNER JOIN t_phoneModel ph on t1.phoneModelid = ph.phoneModelid             
    where qh.QuoteHeaderId = h2.QuoteHeaderId 
    FOR XML PATH('') 
    ) AS PhoneModel 
FROM t_QuoteHeader qh 
INNER JOIN t_handsetQuote h on qh.QuoteHeaderId = h.QuoteHeaderId 
INNER JOIN t_CustomerAdditionalInformation ch on qh.CustomerId = ch.CustomerId 
and keyName ='SendUpdatesByEmail' AND ch.value = 'yes' 

Answer 1

我認爲nvarchar(400)無法處理您插入到它的字符串的長度。

如何更改，恕不insert語句您PhoneModel nvarchar(400)到PhoneModel varchar(MAX)

Answer 2

運行你的選擇查詢，並檢查ph.ModelName + ','的len。它可以通過記錄來記錄不同。

運行您的查詢並提供反饋。看到發生了什麼導致了問題

最簡單的辦法是使用SELECT ... INTO：

SELECT qh.QuoteHeaderId, 
    (Select ph.ModelName + ',' 
    FROM t_handsetQuote h2 
     INNER JOIN t_PhoneAudit t1 on t1.PhoneAuditId = h2.QuotePhoneAuditId 
     INNER JOIN t_phoneModel ph on t1.phoneModelid = ph.phoneModelid             
    where qh.QuoteHeaderId = h2.QuoteHeaderId 
    FOR XML PATH('') 
    ) AS PhoneModel 
into #orders 
FROM t_QuoteHeader qh 
INNER JOIN t_handsetQuote h on qh.QuoteHeaderId = h.QuoteHeaderId 
INNER JOIN t_CustomerAdditionalInformation ch on qh.CustomerId = ch.CustomerId 
and keyName ='SendUpdatesByEmail' AND ch.value = 'yes' 

，然後通過訂購LEN（PhoneModel）遞減檢查所創建的表
