Question

我不是棚里最锋利的工具，所以请耐心等待。我正在尝试将csv文件导入Microsoft SQL Server 2016.但是，每当我尝试这样做时，我都会遇到错误。我认为它可能与管道角色有关。我收到文件的网站有这样说：

文本字段由管道符（ascii 124）包围。日期和数字字段不是。逗号分隔所有字段。

以下是我的查询：

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

这是我的错误：

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

问题涉及列的大小。导入功能警告在导入过程中必须进行截断，结果是丢失数据。

增加表格列的大小或删除竖线字符。

Answer 2

在下一版本的SQL Server中，您也可以使用FIELDQUOTE字符。这是介绍自SQL Server 2008以来版本的页面上的documented，可能会让休闲读者感到困惑：

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

与此同时，我最好的建议是将数据加载到临时表中，然后通过删除第一个和最后一个字符将列解析为单独的列。

您可以使用'|,|'作为字段分隔符，只更改第一列和最后一列中的值，从而简化此操作。

导入具有管道字符的CSV文件。错误说截断
