Question

我正在尝试将以下数据库（位于txt文件中）导入到我的SQL Server数据库中：

我已经定义了一个合适的表，然后尝试了以下查询来导入：

BULK INSERT Cities FROM 'C:\Users\***************\worldcitiespop.txt'
WITH (FIRSTROW = 2, FIELDTERMINATOR = ',', ROWTERMINATOR = '\n')

但是出现了以下错误：

Msg 4866，Level 16，State 8，Line 1批量加载失败。专栏在第1行第7列的数据文件中太长。验证是否字段终止符和行终止符是正确指定的。消息7301， 16级，状态2，行1无法获得所需的接口（“IID_IColumnsInfo”）来自OLE DB提供程序“BULK”，用于链接服务器 “（空）”。

似乎认为没有新的行行终止符。如何正确导入数据库？

Answer 1

首先使用此内容创建worldcitiespop.fmt文件（文件最后需要一个空行）：

10.0
7
1  SQLCHAR  0  10 ","        1  Country                SQL_Latin1_General_Cp437_BIN
2  SQLCHAR  0  100 ","        2  City                SQL_Latin1_General_Cp437_BIN
3  SQLCHAR  0  100 ","        3  AccentCity                SQL_Latin1_General_Cp437_BIN
4  SQLCHAR  0  100 ","        4  Region                SQL_Latin1_General_Cp437_BIN
5  SQLCHAR  0  10 ","        5  Population                SQL_Latin1_General_Cp437_BIN
6  SQLCHAR  0  20 ","        6  Latitude                SQL_Latin1_General_Cp437_BIN
7  SQLCHAR  0  20 "\n"      7  Longitude        SQL_Latin1_General_Cp437_BIN

然后像这样加载：

INSERT INTO Cities
SELECT  a.Country, 
        a.City, 
        a.AccentCity, 
        a.Region, 
        CAST(a.[Population] as int) as [Population],
        CAST(a.Latitude as decimal(10,7)) as Latitude, 
        CAST(a.Longitude as decimal(10,7)) as Longitude
FROM OPENROWSET( 
    BULK 'D:\worldcitiespop.txt', FORMATFILE = 'D:\worldcitiespop.fmt', FIRSTROW = 2
    ) AS a;

在我的旧笔记本上，此插页持续约5分钟

从txt文件导入到SQL服务器的数据库不起作用
