sagivo / bulk-upsert-from-temporary-table.sql

Created April 18, 2016 19:05 — forked from seanbehan/bulk-upsert-from-temporary-table.sql

Perform an "upsert" from CSV file using Postgres copy command #sql #psql

	create temporary table temp (symbol varchar(255), open decimal, high decimal, low decimal, close decimal, volume varchar(255), date date );

	create table if not exists stocks (id serial primary key, symbol varchar(255), open decimal, high decimal, low decimal, close decimal, volume varchar(255), date date, created_at timestamp, updated_at timestamp);

	copy temp (symbol, date, open, high, low, close, volume) from '/path/to/file.csv' with delimiter ',' csv header;

	delete from stocks using temp where stocks.date = temp.date and stocks.symbol = temp.symbol;

	insert into stocks (symbol, open, high, low, close, volume, date) select symbol, open, high, low, close, volume, date from temp;
