Recently, I wrote a post about inserting pandas DataFrame values into a PostgreSQL table, using SQLAlchemy data types to type cast them to the desired data type. In this post, I’ll explore – and leverage – pandas.concat() and get a two for one by merging 2 pandas DataFrames into 1, prior to uploading.
[Head this way for great PostgresSQL blogging >>>]My goal with this post is to cover what I have learned while inserting pandas DataFrame values into a PostgreSQL table using SQLAlchemy. Interested in learning about this yourself? Want to see a simple example? You are in the right place so keep reading and learn with me…
[Head this way for great PostgresSQL blogging >>>]Having previously covered a couple of different ways to upload a CSV’s worth of data into a PostgreSQL table, this post will be quite similar to the second one, with a slight change in the psycopg2 method used. Visit COPY and CAST() – Bulk uploads in PostgreSQL, and Python and psycopg2 for CSV bulk uploads in PostgreSQL – with examples to get up to speed. Aside from that, read on to see the differences between the methods used…
[Head this way for great PostgresSQL blogging >>>]In a previous post, I explored using both the COPY command and the CAST() function together in order to upload an entire CSV file’s data into a PostgreSQL database table. This post is a continuation, of sorts. However, I will use Python and the psycopg2 library, in a simple script, to handle these uploads instead of SQL. While I am still a novice with operations such as these, I feel that writing about it is a fantastic way to learn and obtain valuable feedback…
Loading data into database tables is pretty much a necessity. Without data, what do we have? Not much at all. The CSV format is super common, used far and wide. I keep a CSV file of my daily walking/hiking stats and am looking to store them in a PostgreSQL database on my local learning/development machine. How can I load a CSV – with several rows of data – at one go in Postgres? What about data types? Any concerns there? Continue reading to see a simple, yet effective solution…
