The CSV file contains lines of rows in the result set. The statement created a CSV file named cancelled_orders.csv in the C:\tmp folder that contains the result set.
#Psql export table to csv code
WHERE status = 'Cancelled' INTO OUTFILE 'C:/tmp/cancelled_orders.csv' FIELDS ENCLOSED BY '"' TERMINATED BY ' ' ESCAPED BY '"' LINES TERMINATED BY '\r\n' Code language: SQL (Structured Query Language) ( sql ) To export this result set into a CSV file, you add some clauses to the query above as follows: SELECT WHERE status = 'Cancelled' Code language: SQL (Structured Query Language) ( sql ) OrderNumber, status, orderDate, requiredDate, comments The following query selects cancelled orders from the orders table: SELECT The MySQL server’s process has the write access to the target folder that contains the target CSV file.MySQL provides an easy way to export the query’s result into a CSV file that resides in the database server.īefore exporting data, you must ensure that: It will be useful to have data from MySQL database in CSV file format because you can analyze and format the data in the way you want. The CSV stands for comma separated values. You often use the CSV file format to exchange data between applications such as Microsoft Excel, Open Office, Google Docs, etc.
#Psql export table to csv how to
This post demonstrated stepwise instructions for importing CSV to Postgres or exporting Postgres tables to CSV files using SQL Shell(psql).Summary: in this tutorial, you will learn various techniques of how to export a MySQL table to a CSV file. In Postgres, the “ \COPY” command is used with the collaboration of the “ TO” clause to export a Postgres table to a CSV file using psql. The “ \COPY” command is used with the collaboration of the “ FROM” clause to import a CSV file to a Postgres table. PostgreSQL allows us to import CSV files to Postgres tables or export Postgres tables to CSV files using SQL Shell (psql). The above snippet clarifies that the content from the “employee_info” table has been successfully exported to a CSV file named “employee_data”. To do that, navigate to the directory/location where you exported the selected table:Ī CSV file named “employee_data” has been exported to the specified location. Let’s verify whether the data from the selected table has been exported to a CSV file.
The “COPY 6” message in the output demonstrates that six records have been exported to a CSV file named “employee_data.csv”. Step 2: Export the Table’s Data to CSV FileĮxecute the “\COPY” command with the “TO” clause to export a Postgres table to a CSV file: \COPY employee_info(e_id, e_name, e_email) The following snippet shows the table’s data that we want to export to the CSV file: This way, you can import data from a CSV file to a PostgreSQL table via SQL SHELL.
You can verify it via the following command: SELECT * FROM employees_details Step 4: Verify the Working of \COPY Command The “COPY 14” message in the output demonstrates that 14 records have been imported to the “employees_details” table from the CSV file. The following snippet shows the table’s structure in which we will import the CSV file:Įxecute the “\COPY” command from SQL Shell to import a CSV file into a Postgres table: \COPY employee_details(e_id, e_name, e_experience)įROM 'C:\Users\DELL\Downloads\employee_data.csv' The below snippet shows the CSV file to be imported into a Postgres table: The COPY command will copy all the data from the targeted file to a Postgres table. This post will demonstrate how to import or export CSV files to PostgreSQL via SQL Shell or psql. The primary use case of CSV files is transferring data from one platform to another, such as exporting data to CSV files or importing data from CSV files. The CSV format is used to save data in text files. CSV(acronym of Comma Separated Values) is a format/standard supported by various apps, such as google sheets, MS Office, etc.
