I have csv file that has contents like this:
10,53073,0,0,'Y','2008-05-30 21:46:55',0,'2008-05-30 21:48:04',0,53071,2
I want to load the csv data into 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]))
)
When I run this command in pgAdmin III tool:
COPY my_table FROM 'c:\downloads\file.csv' DELIMITERS ',' CSV;
I got error:
ERROR: value too long for type character(1)
CONTEXT: COPY my_table, line 1, column isactive: "'Y'"
Then I modified the command like this:
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 \;
All failed when tried.
So, anyone can show me the correct COPY command for this case?
Double single quotes (if standard_conforming_strings
is on, see the docs)
COPY my_table FROM 'c:\downloads\file.csv' DELIMITERS ',' CSV QUOTE '''';
or use the non-standard PostgreSQL-specific escape string:
COPY my_table FROM 'c:\downloads\file.csv' DELIMITERS ',' CSV QUOTE E'\'';
