mysql - 通过命令行将某些列从 csv 导入到 mysql

Question

我有一个 csv 文件，想将其中的一部分导入我的 Mysql 数据库。来自 this question , 我在我的 Mysql 命令行中试过这个命令

 load data local infile 'mycsv.csv’ into table mytable fields terminated by ',' enclosed by '"' lines terminated by '\n' (entity_ticker,harvested_at, entity_sector,entity_competitors,story_type,story_source,event,entity_sentiment,event_sentiment,event_relevance,entity_relevance,entity_industry)

括号中的是我要放入表格中的列。顺序与我的表格相同，但与 csv 文件不同。

而 mysql 并没有做这样的事情:

mysql>  load data local infile '2013first1000.csv’ into table news_dataset fields terminated by ',' enclosed by '"' lines terminated by '\n' (entity_ticker,harvested_at, entity_sector,entity_competitors,story_type,story_source,event,entity_sentiment,event_sentiment,event_relevance,entity_relevance,entity_industry)
    "> 
    "> 
    "> 
    "> 

这是我在 txt 中打开的文件的前两行:

signal_id,story_id,story_group_id,new_story_group,story_group_count,source_id,author_id,story_type,story_source,templated_story_score,story_traffic,story_group_traffic_sum,story_group_exposure,entity_sentiment,event_sentiment,story_sentiment,story_group_sentiment_avg,story_group_sentiment_stdev,entity_name,entity_ticker,entity_exchange,entity_relevance,entity_country,entity_indices,entity_industry,entity_region,entity_sector,entity_competitors,entity_type,entity_composite_figi,entity_exch_code,entity_figi,entity_market_sector,entity_security_description,entity_security_type,entity_share_class_figi,entity_unique_id,entity_unique_id_fut_opt,entity_author_republish_score,entity_author_timeliness_score,entity_source_republish_score,entity_source_timeliness_score,event,event_group,event_relevance,event_author_republish_score,event_author_timeliness_score,event_source_republish_score,event_source_timeliness_score,event_impact_pct_change_avg,event_impact_pct_change_stdev,event_impact_pos,event_impact_neg,event_impact_gt_mu_add_sigma,event_impact_lt_mu_sub_sigma,event_impact_gt_mu_pos_add_sigma_pos,event_impact_lt_mu_neg_sub_sigma_neg,event_impact_gt_mu_pos_add_2sigma_pos,event_impact_lt_mu_neg_sub_2sigma_neg,event_impact_gt_1pct_pos,event_impact_lt_1pct_neg,overall_source_timeliness_score,overall_source_republish_score,overall_author_republish_score,overall_author_timeliness_score,harvested_at 5a431613914455535dd2f7e3,59a8c0cb631131661f7cca72,629355b4-5ef4-45ab-872a-9fd1809ca49d,f,552,hW9kPL6pMO0suREcwfIObD7SjwY=,A/mu8VqEc7agwge3hbjXgdFfDeA=,news,broadcastengineering.com,,11548,308325207322,high,31.2,33.35,31.2,36.9,38.9,Sony Corp Ord,SNE,NYSE,100,N/A,[],Consumer Electronics/Appliances,N/A,Consumer Non-Durables,"[""MSFT"",""IBM"",""INTC"",""4331"",""NOKIA"",""HPQ"",""DIS"",""MSI"",""AAPL"",""PHG""]",US_EQUITY,BBG000BT7ZK6,UN,BBG000BT81N7,Equity,SNE,ADR,BBG001S5W6H8,EQ0010136500009000,,0,70.2,0.9566,40.4852,Employment Actions - General,Employment Actions,50.8,,,0,32.5118,,,,,,,,,,,,,53.7511,0.53,0,64.2908,2013-08-01T00:00:03.000Z

你能告诉我怎么做吗？

Answer 1

1) '顺序与我的表相同，但与 csv 文件不同。'- 使顺序相同那么使用 csv 导入的目的是什么？ 用这个-

load data local infile 'mycsv.csv' into table mytable fields terminated by ',' enclosed by ' ' lines terminated by '\n' 

2) 仍然想忽略列-来自 Mysql 文档:

您还可以通过将输入值分配给用户变量而不是将变量分配给表列来丢弃输入值:

LOAD DATA INFILE 'file.txt'  
INTO TABLE t1 (column1, @dummy, column2, @dummy, column3);

3) 跳过第一行 - 使用忽略 1 行
