導入具有管道字符的CSV文件。錯誤稱截斷

Question

我不是棚屋裏最鋒利的工具，請耐心等待。我正在嘗試將csv文件導入Microsoft SQL Server 2016.但是，每當我嘗試執行此操作時，都會遇到錯誤。我認爲這可能與管道角色有關。我從網站上得到的文件有這樣的說法：

文本字段被管道字符（ascii 124）包圍。日期和數字字段不是。逗號分隔所有字段。

這裏是我的查詢看起來是這樣的：

CREATE TABLE cands16 (
    [Cycle] [char](4) NOT NULL, 
    [FECCandID] [char] (9) NOT NULL, 
    [CID] [char] (9) NULL, 
    [FirstLastP] [varchar] (50) NULL, 
    [Party] [char] (1) NULL, 
    [DistIDRunFor] [char] (4) NULL, 
    [DistIDCurr] [char] (4) NULL, 
    [CurrCand] [char] (1) NULL, 
    [CRPICO] [char] (1) NULL, 
    [RecipCode] [char] (2) NULL, 
    [NoPacs] [char] (1) NULL 
) ON [PRIMARY] 


BULK 
INSERT cands16 
FROM 'C:\aaa open secrets\CampaignFin16\Cands16.txt' 
WITH 
(
FIELDTERMINATOR = ',', 
ROWTERMINATOR = '\n' 
) 
GO 

這是我的錯誤：

Msg 4863, Level 16, State 1, Line 19 
Bulk load data conversion error (truncation) for row 1, column 1 (Cycle). 
Msg 4863, Level 16, State 1, Line 19

Answer 1

該porblem關於列的大小。導入功能警告在導入過程中必須進行截斷，導致數據丟失。

增加表格列的大小或刪除管道字符。

Answer 2

在下一個版本的SQL Server，您也可以使用FIELDQUOTE字符。這是好心documented描述，因爲SQL Server 2008的版本在頁面上，可能混淆普通讀者：

BULK INSERT cands16 
    FROM 'C:\aaa open secrets\CampaignFin16\Cands16.txt' 
WITH (FIELDTERMINATOR = ',', 
     ROWTERMINATOR = '\n', 
     FIELDQUOTE = '|' 
    ); 

在平均時間，我最好的建議是將數據加載到一個臨時表，然後解析通過刪除第一個和最後一個字符將列分成單獨的列。

您可以通過使用'|,|'作爲字段分隔符並僅更改第一列和最後一列中的值來簡化此操作。
