Question

Hy，我知道已经有很多问题已经提出来，但这有点不同。我有包含数百万条记录的csv文件。我尝试了以下命令从csv复制到我的表，即

copy "client_data" from '/home/mike/Desktop/client_data.txt' with delimiter ',' CSV;

但问题是因为csv中的数据是不一致的状态，即

以下几行会有魅力

12/12/12 20:17:35,304000000,"123","1"
12/12/12 20:17:36,311000000,"123","2"
12/12/12 20:17:36,814000000,"123","2"
12/12/12 20:17:36,814000000,"123","2"
12/12/12 20:17:37,317000000,"123",".1"
12/12/12 20:17:38,863000000,"123","TS"
12/12/12 20:17:39,835000000,"123","2"
12/12/12 20:17:40,337000000,"123","1"

但数百行就像

12/12/12 20:20:03,790000000,"123","1
{'""}__{""'}        /""'\
(      $AMZA./)@FRIDI
{__}""'{__}     /)      (\. ,,DON,,"



12/12/12 20:20:30,501000000,"123","INAM NIKALTA NHE HE KITNE SAWALO K JAWB DAY 
 /G\A\,':/\,':/S\K,':\"


12/12/12 20:22:55,928000000,"123","PAKISTAN KI BUNYAAD 
2=QUAID-E-AZAM"
12/12/12 20:22:56,431000000,"123","QUIED E AZAM

由于换行符，逗号，无效字符等而无法解析有没有办法解析这些并以有效的方式加载postgres表中的数据？

下面是表格结构

create table "client_data" (

date_stamp text,
points bigint,
msisdn character varying(13),
data text
)
with (OIDS = false);
alter table "client_data" owner to postgres;
