Inserting data using COPY and a CSV file

Inserting data with the cqlsh command COPY from a CSV file is common for testing queries.

In a production database, inserting columns and column values programmatically is more practical than using cqlsh, but often, testing queries using this SQL-like shell is very convenient. A comma-delimited file, or CSV file, is useful if several records need inserting. While not strictly an INSERT command, it is a common method for inserting data.

Procedure

  1. Locate your CSV file and check options to use. 
    category|point|id|lastname
GC|1269|2003|TIRALONGO
One-day-races|367|2003|TIRALONGO
GC|1324|2004|KRUIJSWIJK
  2. To insert the data, using the COPY command with CSV data. 
    $ COPY cycling.cyclist_catgory FROM 'cyclist_category.csv' WITH DELIMITER='|' AND HEADER=TRUE
