postgresql – PG COPY错误：导入带有任何整数的引用CSV文件时,“整数输入语法无效”

在一个简单的示例数据库中尝试通过Postgres 9.5.1中的sql使用 COPY命令时…

我收到此错误：

ERROR:  invalid input Syntax for integer: "Sally"
CONTEXT:  copY customer_,line 2,column id_: "Sally"

********** Error **********

ERROR: invalid input Syntax for integer: "Sally"
sql state: 22P02
Context: copY customer_,column id_: "Sally"

…以CSV格式导入此数据时(逗号分隔值)：

"first_name_","last_name_","phone_","email_"
"Sally","Jones","425.555.1324","[e-mail]"
"Jarrod","Barkley","206.555.3454","[email protected]"
"Wendy","Melvin","415.555.2343","[email protected]"
"Lisa","Coleman","425.555.7282","[email protected]"
"Jesse","Johnson","507.555.7865","[e-mail]"
"Jean-Luc","Martin","212.555.2244","[email protected]"

…通过pgAdmin中执行的以下sql导入：

copY customer_
FROM '/home/parallels/Downloads/customer_.csv'
CSV 
HEADER
;

…进入此表：

-- Table: public.customer_

-- DROP TABLE public.customer_;

CREATE TABLE public.customer_
(
  id_ integer NOT NULL DEFAULT nextval('customer__id__seq'::regclass),first_name_ text NOT NULL,last_name_ text NOT NULL,phone_ text NOT NULL DEFAULT ''::text,email_ text NOT NULL DEFAULT ''::text,CONSTRAINT pkey_customer_ PRIMARY KEY (id_)
)
WITH (
  OIDS=FALSE
);
ALTER TABLE public.customer_
  OWNER TO postgres;
COMMENT ON TABLE public.customer_
  IS 'Represents a person  whose pets visit our clinic.';

因此,似乎包含列名称的第一行正在成功处理.失败点是CSV的第一个数据行中的第一个数据值.我导入的所有数据都不是整数类型,所以我对错误信息感到困惑.唯一的整数是id_主键,自动递增SERIAL.

我确实在PG COPY error: invalid input syntax for integer阅读了问题页面.但是这个问题确实涉及整数值,并且缺少空引用字符串被解释为NULL.就我而言,我们在数据中没有整数值;唯一的整数是具有DEFAULT生成值的主键SERIAL列(不在要导入的数据中).

我也找到了问题,PostgreSQL ERROR: invalid input syntax for integer.但似乎无关紧要.

尝试指定列. . .没有主键：

copY customer_ (first_name_ text,last_name_ text,phone_ text,email_ text)
FROM '/home/parallels/Downloads/customer_.csv'
CSV 
HEADER
;

没有列列表,它正在寻找id_的值.

导入数据文件的第一行列名不用于映射到表列. HEADER标志只是告诉Postgres跳过第一行as documented：

HEADER

Specifies that… on input,the first line is ignored. …
