Importing data from a CSV file

In a production database, inserting columns and column values programmatically is more practical than using cqlsh, but often, testing queries using the cqlsh 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.

  1. Locate your CSV file and check options to use.

    category|points|id|lastname
    GC|1269|220844bf-4860-49d6-9a4b-6b5d3a79cbae|SMITH
    One-day-races|367|220844bf-4860-49d6-9a4b-6b5d3a79cbbd|ALBERT
    GC|1324|220844bf-4860-49d6-9a4b-6b5d3a79cbab|DOE
  2. To insert the data in the CSV file, use the COPY command:

    COPY cycling.cyclist_category
    FROM 'cyclist_category.csv'
    WITH DELIMITER = '|'
      AND HEADER = TRUE;
