How to Modify Database Tables

How This Workflow Works

This workflow connects to a database, demonstrates how to create new tables, and insert and process data. It also covers how to bring data from the database back into your analysis environment, and remove existing tables as needed.

Key Features:

  • Create and insert new database tables for data storage
  • Process and transform data directly within the database
  • Remove outdated or unnecessary tables to maintain database hygiene

Step-by-step:

1. Create Database Tables:

The workflow starts by establishing a connection to the target database and creating new tables with the required structure. This step ensures that the database is ready to store new or updated data according to business needs.

2. Insert Data in Tables:

Data is written into the newly created tables by direct insertion. This step returns information on the insertion status and possible errors that may have arisen during the operation.

3. Process Data In the Database:

The workflow applies in-database processing, such as filtering, sorting, and renaming columns, to prepare the data for analysis or reporting. These operations help refine the dataset without moving large volumes of data outside the database.

4. Read Data Back for Analysis or Remove Unnecessary Tables:

Finally, the workflow retrieves processed data from the database and imports it back into the analysis environment. Additionally, when tables are no longer needed, the workflow removes them from the database. This helps keep the database organized and prevents clutter from obsolete data structures.
