Providing the path and column count of your CSV file, you can use the following function to load your table to a temp table that will be named as target_table: This may not be practical in some cases (e.g., if you have a lot of columns in the destination table). Most other solutions here require that you create the table in advance/manually.

Here's a simple example: import pandas as pdĭf.columns = # PostgreSQL doesn't like capitals or spacesĪnd here's some code that shows you how to set various options: # Set it so the raw SQL output is logged If it doesn't quite do what you want you can always use the 'create table' code generated as a template. This will handle creating the columns for you - although obviously the choices it makes for data types might not be what you want. One quick way of doing this is with the Python Pandas library (version 0.15 or above works best). Thus, file accessibility and access rights depend on the client rather than the server when \copy is used.įor identity columns, the COPY FROM command will always write the column values provided in the input data, like the INSERT option OVERRIDING SYSTEM VALUE. \copy invokes COPY FROM STDIN or COPY TO STDOUT, and then fetches/stores the data in a file accessible to the psql client. You can also specify the columns to read: \copy zip_codes(ZIP,CITY,STATE) FROM '/path/to/csv/ZIP_CODES.txt' DELIMITER ',' CSVĭo not confuse COPY with the psql instruction \copy. must be written in one line and without a at the end!

(ZIP char(5), LATITUDE double precision, LONGITUDE double precision,ĬITY varchar, STATE char(2), COUNTY varchar, ZIP_CLASS varchar) Ĭopy data from your CSV file to the table: \copy zip_codes FROM '/path/to/csv/ZIP_CODES.txt' DELIMITER ',' CSV Using the same example as Bozhidar Batsov:Ĭreate your table: CREATE TABLE zip_codes If you don't have permission to use COPY (which work on the db server), you can use \copy instead (which works in the db client).
