我有了这样的内容CSV文件:
10,53073,0,0,'Y','2008-05-30 21:46:55',0,'2008-05-30 21:48:04',0,53071,2
我想CSV数据加载到MY_TABLE。
CREATE TABLE my_table
(
ad_tree_id numeric(10,0) NOT NULL,
node_id numeric(10,0) NOT NULL,
ad_client_id numeric(10,0) NOT NULL,
ad_org_id numeric(10,0) NOT NULL,
isactive character(1) NOT NULL DEFAULT 'Y'::bpchar,
created timestamp without time zone NOT NULL DEFAULT now(),
createdby numeric(10,0) NOT NULL,
updated timestamp without time zone NOT NULL DEFAULT now(),
updatedby numeric(10,0) NOT NULL,
parent_id numeric(10,0),
seqno numeric(10,0),
CONSTRAINT ad_treenodemm_pkey PRIMARY KEY (ad_tree_id , node_id ),
CONSTRAINT adtree_adtreenodemm FOREIGN KEY (ad_tree_id)
REFERENCES ad_tree (ad_tree_id) MATCH SIMPLE
ON UPDATE NO ACTION ON DELETE CASCADE DEFERRABLE INITIALLY DEFERRED,
CONSTRAINT ad_treenodemm_isactive_check CHECK (isactive = ANY (ARRAY['Y'::bpchar, 'N'::bpchar]))
)
当我运行中的pgAdmin III工具下面的命令:
COPY my_table FROM 'c:\downloads\file.csv' DELIMITERS ',' CSV;
我得到的错误:
ERROR: value too long for type character(1)
CONTEXT: COPY my_table, line 1, column isactive: "'Y'"
然后我修改的命令是这样的:
COPY my_table FROM 'c:\downloads\file.csv' DELIMITERS ',' CSV QUOTE ''';
COPY my_table FROM 'c:\downloads\file.csv' DELIMITERS ',' CSV QUOTE '\'';
COPY my_table FROM 'c:\downloads\file.csv' DELIMITERS ',' CSV QUOTE '\'' ESCAPE '\';
COPY my_table FROM 'c:\downloads\file.csv' DELIMITERS ',' CSV QUOTE '\'' ESCAPE \;
当尝试都失败。
所以,任何人都可以告诉我这种情况的正确COPY命令?
