我有这个包含大约 16.916 条记录的CSV 文件。当我将它加载到 MySQL 中时,它只检测到 15.945 条记录。这就是 MySQL 所说的:
Records: 15945 Deleted: 0 Skipped: 0 Warnings: 0
有人能告诉我为什么 MySQL 会忽略一些记录以及如何解决这个问题吗?
我使用 LOAD 函数加载文件,如下所示:
LOAD DATA LOCAL INFILE 'germany-filtered.csv'
INTO TABLE point_of_interest
FIELDS TERMINATED BY ','
ENCLOSED BY '"'
LINES TERMINATED BY '\n'
IGNORE 1 LINES
(osm_id,lat,lng,access,addr_housename,addr_housenumber,addr_interpolation,admin_level,aerialway,aeroway,amenity,area,barrier,bicycle,brand,bridge,boundary,building,capital,construction,covered,culvert,cutting,denomination,disused,ele,embankment,foot,generator_source,harbour,highway,historic,horse,intermittent,junction,landuse,layer,leisure,ship_lock,man_made,military,motorcar,name,osm_natural,office,oneway,operator,place,poi,population,power,power_source,public_transport,railway,ref,religion,route,service,shop,sport,surface,toll,tourism,tower_type,tunnel,water,waterway,wetland,width,wood);
这就是我使用的数据库模式:
CREATE TABLE point_of_interest (
`poi_id` int(10) unsigned NOT NULL auto_increment,
`lat` DECIMAL(10, 8) default NULL,
`lng` DECIMAL(11, 8) default NULL,

更新:
我已经检查了第一条和最后一条记录,但两者都存在。也确实存在具有很多这样的空值的记录:
1503898236,10.5271308,52.7468051,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,
更新 2:
这些是我发现的数据库中缺少的记录:

似乎几乎所有osm_id
以 a 开头的记录4
都丢失了。那很奇怪。
