QUOTE: Specify the character used to quote the data values.Some of the important ones are listed below:
The COPY command has many optional parameters that you can use to customize its behavior.
#PGADMIN 4 EXPORT QUERY TO CSV SERIAL#
COPY customer(first_name,last_name,email) FROM '/home/data/customers1.csv' DELIMITER ',' CSV HEADER Skipping the serial column If you want to skip loading the serial column and want to load only first_name, last_name, and emailYou can use the command below instead. COPY customer FROM '/home/data/customer.csv' DELIMITER ',' CSV HEADER The COPY command We can now use the COPY command to insert the data into the customer table. You can do this in Excel or any other spreadsheet-type program.
Now, create a CSV file in the below format. The above command results in a customer table with four columns. The first step is to use the CREATE TABLE command to create a table. Want to see the COPY command in action? Follow along with the steps below. By contrast, the TEXT format follows Postgres-specific escaping rules. But if your input is CSV, it is better to use the CSV format with the DELIMITER option rather than the TEXT format since CSV format adheres with commonly accepted CSV escaping mechanism. On successful completion, the COPY command outputs result in the format COPY count, denoting the number of rows inserted by the command.īoth the text and the CSV file formats allow you to specify a delimiter. It also allows you to specify a list of columns to insert the data into instead of the whole table. The command can also use a SELECT query to load data to a table. The file mentioned in the COPY command must be accessible by the Postgres user and should be specified from the perspective of the Postgres server. You can also use the COPY FROM command to load the data from a file to the table. For example, the COPY TO command outputs the content of a table to a file. The COPY command can import data to Postgres if access to text, CSV, or binary format data. Method 1: Using the COPY command for Postgres Which method is fastest and easiest will depend on your setup and how the data exists right now. You can use the COPY command, restore from a backup, or load in a CSV with a SQL GUI tool. What is a database without data? Postgres provides multiple options to import data from files.
