Now before moving further make sure you have the necessary tools installed on your system, you should have a local version of Postgres server installed on your computer or an access to a remote Postgres server. Relational databases are commonly used as data storage for web contents, big businesses and other data platforms. The PostgreSQL is a type of data storage called a relational database.It is one of the biggest open source relational databases. In the below example, we have import CSV file into the table by using shell prompt.In this article, we will discuss two different ways to populate a PostgresSQL database with a csv file. Import CSV file into a table from shell prompt We have used the stud_test table to import the data from the CSV file.ģ. In the below example we have import CSV file into the table without using header. Import CSV file into a table without using header We have used the stud_test table to import the data from the CSV file.Ģ. In the below example, we have import CSV file into the table by using header. Import CSV file into table by using header

We have using stud_test table to describe example of import CSV file into PostgreSQL table.īelow is the structure of stud_test table.ĬREATE TABLE stud_test( id serial NOT NULL, f_name character varying(10), l_name character varying(10), dob date, email character varying(20)) ġ. There is no need to define header when the header is not present in the CSV file.īelow example shows that we need to define header when CSV file contains the header.ĬOPY stud_test FROM '' DELIMITER ',' CSV HEADER Įxamples to Implement Import CSV in PostgreSQL.

If the CSV file contains the header then we need to define the header in copy command.

The header is defined in the first line of the CSV file.

The header is nothing but the column name which was we have defined in table.

Some CSV file contains the header or some file is not contains the header.

The delimiter is very important while importing data from CSV file into the table. Tab-separated values in PostgreSQL is also known as the TSV file. We can also separate the values using ‘|’, tabs ‘\t’ or newline ‘\n’. Below is the example that we required same name of column and data while importing data into the table.Ĭopy import_test (id) from '' DELIMITER ',' CSV /]# cat /Test.csvīasically we have separate the values using a comma, but in some file, we have used another delimiter to separate the values. If column name and data is mismatch then it will issue error as “ERROR: extra data after last expected column”. Number and data type of column need to be same and which was present into the CSV file.Mismatch of column is not allowed while importing data from CSV file. To import the data from CSV file into the table, same table is created with same name and same structure. Create table with same structure of CSV file To import the data from CSV file into the table we need to follow below things or same table is present on database. We have using copy command in PostgreSQL to import the file. Data have their header to defined or import the data from file.īelow is the working of import CSV file into the table in PostgreSQL.

Header of CSV file: This is defined as the column name of the table on which we have imported data from the CSV file.

We can use any delimiter to separate the value of a column in PostgreSQL.

Delimiter: This is defined as the value which was separated by a semicolon.

It is defined as the path of the file, we need to define the absolute path with copy command in PostgreSQL.

Filename or path of file: This is specify that name of file from which we have imported data into the table.

From: This keyword is used to specify the CSV file name from which we have importing the data into the table.The column name specifies that we have to insert or load the data from the CSV file on which column that we have specify in copy command. Column name1 to column names: We have to define column name with the copy command.Table name: The table name specifies the name of table on which we have imported the data from CSV file.The copy command is very useful to import the data into the PostgreSQL table. Copy: This is a command in PostgreSQL used to import the data from the CSV file into the table.Hadoop, Data Science, Statistics & othersĬOPY table_name (Column_name1, column_name2, …, column_nameN) from file_name (Path of file) Delimiter CSV ĬOPY name_of_table from name_of_file Delimiter īelow is the parameter description syntax of import CSV into the PostgreSQL table.
