Performing scan queries

You can run a query using Scan Queries via the YDB CLI by adding the -t scan flag to the ydb table query execute command.

Run the data query:

1. ydb table query execute -t scan \
2. --query "SELECT season_id, episode_id, title \
3. FROM episodes \
4. WHERE series_id = 1 AND season_id > 1 \
5. ORDER BY season_id, episode_id \
6. LIMIT 3"
