This method of uploading a csv file into a Postgres server is very simple and unique, the sqlalchemy toolkit takes care of many things in the backend. In the end we commit the whole transaction block and successfully loaded the class.csv into our table. However, it differs from the execute() method due to its parameters, here we have passed 'f' a file object as an argument along with the tablename in which we want to upload the csv file and "sep" is the specified delimiter of the fields (columns) of the csv file. Loading csv file : Here we use copy_from() method which like the execute() method is also attached to the Cursor object. (Till this time you probably would have encountered a couple of glitches but don't worry mention them in comments, we will sort it out.) (Hints rollback() and set_isolation_level() ) If you are familiar with the concept of sql-transactions then you would know that commit() method must be run in the end to create our table. conn = ps.connect(host='name_of_host_server',

In the end we have closed the connection. So, with the connect() method we created a connection object here using which we created a cursor object which we have to use to execute our commands.

In the next lines of code we will create a database. But, can you see that I have not passed a ' database' parameter, why? Because we will create one through this connection! I have just created an instance of the server for now. Then, we need to pass in the port number which by default is 5432 for Postgres server and a username .

It is necessary to specify a host describing where your Postgres server is running, usually the name 'localhost' is taken as a standard practice. Let us describe these parameters that we have passed into the nnect() method.

Using psycopg2: pip install psycopg2Ĭonnecting to Postgres server import psycopg2 as psĬonn = ps.connect(host='name_of_host_server', First let us start with psycopg2 library installation. Now, we will run through an example of creating a database and a table from scratch and then load a data set into a local running Postgres server. The resources we are using here are two Python libraries pandas and psycopg2 and a open-source SQL toolkit SQLAlchemy for Python programming language. ( link for Postgres installation guide wiki page ) 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. I used psql to push the CSV file to the table, as suggested by psql -h port -d db -U user -c "\copy products from 'products.csv' with delimiter as ',' csv header " It only took a couple of minutes to copy the table, compared to 10+ hours with the python script.In this article, we will discuss two different ways to populate a PostgresSQL database with a csv file.

It also makes it easy to issue queries, retrieve data, and download result sets to CSV, JSON, SQL, or other common data formats. Therefore, it must be accessible to the PostgreSQL server machine.ĭBeaver Community Edition (dbeaver.io) makes it trivial to connect to a database, then import a CSV file for upload to a PostgreSQL database. The file must be read directly by the PostgreSQL server and not by the client application. When importing data, PostgreSQL neglects the first line as they are the header line of the file. The HEADER keyword indicates that the CSV file comprises a header line with column names. However, even at a brisk 15 records per second, it would take a whopping 16 hours to complete. The following statement truncates the persons table so that you can re-import the data.įaced with importing a million-line, 750 MB CSV file into Postgres for a Rails app, Daniel Fone did what most Ruby developers would do in that situation and wrote a simple Rake task to parse the CSV file and import each row via ActiveRecord. In case you need to import a CSV file from your computer into a table on the PostgreSQL database server, you can use the pgAdmin. Import CSV file into a table using pgAdmin.
