01 Practicing with Traditional Databases

L4-BD SELF-PACED COURSE exercise:
- Remove, structure, create, and manipulate database tables







Exercise 1: Practicing with Traditional DatabasesIn this exercise you'll create a database table, and load and manipulate airline data (US domestic flights in January 2007) in the database.1) Read the AirlineDataset.table file and connect to the H2 database by executing the nodes below2) Create a new table "airline" on the database based on the table specs of the local data table. Replace the existing table. Use dynamic settings.3) Insert the data into the airline database tablePerform the following tasks directly on the database using the DB nodes:4) Filter the data to flights that were not cancelled AND had Austin-Bergstrom International Airport ("AUS") as destination5) Write the filtered data into a new database table called "airline_Austin" 6) Read the airline_Austin table into KNIME7) Optional: Delete the cancelled flights directly on the database with the following statement in the DB SQL Executor node:DELETE from "PUBLIC"."airline" where "Cancelled" = 1; database.mv.dbAirlineDataset.tableNode 59Node 60Node 61Node 62Node 63H2 Connector Table Reader DB Table Creator DB Insert StringConfiguration StringConfiguration DB Row Filter Exercise 1: Practicing with Traditional DatabasesIn this exercise you'll create a database table, and load and manipulate airline data (US domestic flights in January 2007) in the database.1) Read the AirlineDataset.table file and connect to the H2 database by executing the nodes below2) Create a new table "airline" on the database based on the table specs of the local data table.
