Choose Your Favorite Food and Create View (SAP TechEd)


Choose your favorite foods in the database and create a database view.

You will learn

  • How to create a database view
  • How to use fuzzy search on a text column

This mission can only be completed at SAP TechEd.

Step 1: Explore the data

The project you have just cloned is using tables in a shared HDI container, which you can access through synonyms.

Right-click on the db folder and choose Open HDI Container.

Explore data

You should see your own HDI container. Click Synonyms. Choose the table COMM_FOODS and then click Generate SELECT Statement.

Explore data

Scroll all the way down to the FROM statement to answer the validation below.

What does the name of the schema look like?
Step 2: Choose your favorite food

Press F8 or click run to execute the statement. You will see some of the foods included in the table.

Think of your favorite food, replace the placeholder below and introduce the following into fuzzy search as a where clause to look for it.

where contains(product_name, '<<YOUR FAVORITE FOOD HERE>>', fuzzy(0.8,'textsearch=compare'))
AND to_nvarchar("PURCHASE_PLACES") <> 'NULL';

Run run the statement and make sure you get results.

Explore data

If you do not get any results, try a different food item or use the same example. Leave this SQL tab and results open.

Note how the ingredients are a long text separated by commas.

		TO_INT("ID") as "ID",
