Browse and Explore Catalog Objects with the Database Objects App

1. Ensure that your database instance is running before attempting to open the Database Objects app.

   The application can be opened from the actions menu of an instance or directly from the list of applications on the left side bar of SAP HANA Cloud Central.

   

   You can also open the database objects app through the SQL Console as shown below.

   

2. Upon opening database objects, click Select an Instance at the top of the page to choose the database you want to work with. You can browse the list or use the search field to quickly find your instance.

   

   

   Once selected, the Search and Schema filters are both available to use. Select the Schema filter and search for the HOTELS schema.

   

   You can also search for the schema or any other objects directly in the Search filter. In this case after searching navigate to the Schemas tab directly to view the metadata for the HOTELS schema. This data includes ownership, privileges and create time.

   

Information for tables includes columns, indexes, properties, runtime information and SQL CREATE Statements.

1. Select the Tables tab to view all associated tables of the HOTELS schema.

   The page now displays all tables in the schema HOTELS and their table type.

   

2. Select the RESERVATION table to explore it further.

   Click the full screen icon on the top right of the screen to maximize the page and view all tabs.

   

   By default you should see the column details for the table.

   

3. Explore the Runtime Information tab, where further information about the table can be found. This information includes the total number of rows, disk size, partitions and memory consumption for the table, as well as individual columns.

   

4. Examine the other tabs, such as CREATE Statements, where SQL code to generate the table can be found.

   

5. Select the Generate SQL Statement dropdown to see the three ways to have SQL generated for the table.

   

1. To display functions in the Database Objects app, click on Select Object Types and turn on the functions object type. The visibility and order of the database objects can be customized by selecting the checkbox and dragging objects by the drag handle icon.

   

2. Open the Functions tab and select AVERAGE_PRICE to examine it further.

   

   Select the Generate SQL Statement dropdown and click SELECT Statement to navigate to the SQL Console.

   

   Input suite in the single quotes of the SELECT statement to get the average price for suites.

   

3. Navigate back to the Database Objects app and open the Procedure tab. Select RESERVATION_GENERATOR to examine it further.

   

4. Click Generate SQL and select CALL Statement to get SQL that runs the stored procedure.

   

   The following SQL will be generated:

   SQL Copy

   CALL "HOTELS"."RESERVATION_GENERATOR"(NUMTOGENERATE => /*<INTEGER>*/)

   The parameter NUMTOGENERATE expects an integer value, which specifies how many reservations to generate. Replace ** with the desired number of reservations you want the procedure to create.

1. Select the Recent tab to view all the recent objects you opened.

   

2. Navigate to an object and click the star icon on the top right of the screen to favorite it.

   

   Once selected as a favorite, navigate to the Favorites tab to see it.

   

3. Click All/Selected Instance toggle to filter between favorites for the current instance or to show all favorites.

   

4. The SAP HANA database explorer extension for Microsoft Visual Studio Code and the SAP Business Application Studio provide a few additional features that developers may find helpful which include the ability to view and download SAP HANA Cloud trace files, the ability to debug SQL Script, and the ability to maintain a custom list of instances.
