将CSV文本数组导入PostgreSQL 9.2

Question

我有这样的数据:

Akhoond,1,Akhoond,"{""Akhund"",""Akhwan""}",0

pgAdmin的导入拒绝了.文本[]需要采用什么格式在CSV中？

我也试过这个:

Akhoond,1,Akhoond,"{Akhund,Akhwan}",0

这是表创建:

CREATE TABLE private."Titles"
(
  "Abbrev" text NOT NULL,
  "LangID" smallint NOT NULL REFERENCES private."Languages" ("LangID"),
  "Full" text NOT NULL,
  "Alt" text[],
  "Affix" bit
)
WITH (
  OIDS=FALSE
);

ALTER TABLE private."Titles" ADD PRIMARY KEY ("Abbrev", "LangID");

CREATE INDEX ix_titles_alt ON private."Titles" USING GIN ("Alt");

ALTER TABLE private."Titles"
  OWNER TO postgres;

找出最好的方法是创建一个包含所需值的表,并COPY ... TO STDOUT查看:

craig=> CREATE TABLE copyarray(a text, b integer, c text[], d integer);
CREATE TABLE
craig=> insert into copyarray(a,b,c,d) values ('Akhoond',1,ARRAY['Akhund','Akhwan'],0);
INSERT 0 1
craig=> insert into copyarray(a,b,c,d) values ('Akhoond',1,ARRAY['blah with spaces','blah,with,commas''and"quotes'],0);
INSERT 0 1
craig=> \copy copyarray TO stdout WITH (FORMAT CSV)
Akhoond,1,"{Akhund,Akhwan}",0
Akhoond,1,"{""blah with spaces"",""blah,with,commas'and\""quotes""}",0

所以它看起来"{Akhund,Akhwan}"很好.请注意我添加的第二个示例,显示如何处理逗号,引用数组文本中的空格.

这适用于psql \copy命令; 如果它不能与PgAdmin-III一起使用psql,那么我建议使用和\copy.
