How to configure sources

The sources files must be inside the queries/ folder.

To know how the source hierarchy works, please, visit How to configure sources.

​
Configuration

To use CSV files directly within a Latitude project, we use the DuckDB adapter. Make sure to configure the connection through DuckDB by following these steps:

1

Create the source `.yaml` file within the `queries` folder if you haven't already

/queries/source.yml

2

Add the following code for your DuckDB connection

type: duckdb
3

Done, now you can test your connection

​
Add your files

Simply add your CSV files anywhere in the queries directory. You can also create subdirectories to organize your files.

​
Test connection

To test the connection you can:

  1. Create a query .sql in the queries directory that points to the CSV file in the FROM clause using the read_csv_auto() DuckDB function. Here’s an example:
SELECT *
FROM read_csv_auto('queries/file.csv')
  1. Use the command line to run latitude run query_file_name where query_file_name is the name of your .sql file. This will display the results in your terminal. See the section Running queries to learn more about how to query your data.
