I need to convert csv into postgres table. I using the query below:
copy public.itens_2019 from 'C:\itens.csv' delimiter ',' CSV HEADER;
108,62,'C','Falência de Empresários, Sociedades Empresáriais, Microempresas e Empresas de Pequeno Porte','A',,,,
it is possible to observe that the texts are enclosed in quotation marks, because the text has commas. This way I am not able to extract the columns correctly.
try with the below command
copy public.itens_2019 from 'C:\itens.csv' delimiter ',' CSV HEADER QUOTE '''';
You can try with below query for specific column.
copy table_name(column1,column2,column3,column4,column5) from 'C:\itens.csv' DELIMITERS ',' CSV;

Running into an issue with copying the following data into a DB
1, ab\"c
I receive an unterminated quote error when running the following SQL
copy table_name from sample.tsv CSV DELIMITER ',' QUOTE '"' ESCAPE E'\\'
Based on the postgresql documentation I expect the escape parameter to be used to escape the quotation character but it's not working. Would like to see if there's a solution to this issue without reformatting the data, or changing the quote character.
try this. Because if quote is ", then it will mix with double quote in (ab"c).
copy table_name from 'sample.tsv' (FORMAT CSV, QUOTE '''', DELIMITER ',',ESCAPE E'\\');
It is expecting to find escaped quotes only inside quotes, so the command you show would work for 1,"ab\"c" but not for what you have.
The command that would work for the data you show is:
copy table_name from sample.tsv DELIMITER ','
But it is not likely to work for the rest of your data.
I am trying to copy data from a csv file into my database table. But the problem is that a column named title has some values that contain a comma within.
How can I exclude it from being used as a delimiter while parsing?
Sample data:
"Hold On, I'm Coming", The Canettes Blues Band, On Tap & In the Can, 34, 100, 282
I don't want the comma after "Hold on" to be used as a delimiter.
If you are using copy or psql's \copy then use the options
format csv quote '"'
this will make the import ignore commas inside quoted values (which is what your sample data uses)
e.g. in psql
\copy target_table from the_input_file.txt with (format csv quote '"')
I'd like to copy from with csv file with Postgres.
That csv file has array literal whose delimiter is ;.
example: a,b,c,{1;2;3}
I did that with replacing delimiter of csv file , to | and set option delimiter | and replacing delimiter of array literal ; to ,.
example: a|b|c|{1,2,3}
I think there may be option to set delimiter of array literal.
If so, I don't have to replace delimiter of csv file.
Are there any smarter way?
There is no option to configure the separator between the elements of an array in its text representation.
But if you have any control over how the CSV file is generated, you can escape the array literal:
a,b,c,"{1,2,3}"
That would work fine with COPY.
I have the three statements below that all work until it hits a row with an extra tab at the end of the tab delimited text file that I am trying to import.
Any way to tell Postgres to ignore extra tabs?
copy mara FROM 'c:/Postgres MME/AG00_MARA.txt' DELIMITER E'\t' NULL '' CSV HEADER;
copy mara FROM 'c:/Postgres MME/AG00_MARA.txt' DELIMITER E'\t' CSV HEADER;
copy mara FROM 'c:/Postgres MME/AG00_MARA.txt' WITH (FORMAT csv, DELIMITER E'\t', NULL '', HEADER);
Image of Notepad++ Where I see the extra tab at the end of the row
Don't try to ignore it, just fix your data by removing all the trailing tabs with regex \t$. For example in Linux:
sed -i 's/\t$//g' AG00_MARA.txt
I was trying to import a CSV file into a PostgreSQL table using the COPY command. The delimiter of the CSV file is comma (,). However, there's also a text field with a comma in the value. For example:
COPY schema.table from '/folder/foo.csv' delimiter ',' CSV header
Here's the content of the foo.csv file:
Name,Description,Age
John,Male\,Tall,30
How to distinguish between the literal comma and the delimiter?
Thanks for your help.
To have the \ to be recognized as a escape character it is necessary to use the text format
COPY schema.table from '/folder/foo.csv' delimiter ',' TEXT
But then it is also necessary to delete the first line as the HEADER option is only valid for the CSV format.
