Hi devs, In this guide we are going to see how to import millions of rows of data into database from csv file. This might take some time but for doing this we are going to process data using chunk method. So mainly we will process chunk of data and insert it into database and same process repeating again and again.
On we will follow these steps to import data
- Breaking large csv to smaller csv’s.
- reading smaller csv’s and store in database table.
- Each query will insert 1000 rows of data. (Max allowed in single query so).
Download the code zip if you wan it also check the video guide for practical usage.
In video guide we are also verifying if the all data inserted correctly or not.
