HANA examples

These HANA examples show data modeling and SQL on the in-memory database, a calculation/CDS view and set-based SQL, illustrating the code-to-data approach.

Quick answer

The examples embody code-to-data: aggregate and filter in the database (via CDS or SQL) rather than pulling rows into ABAP and looping.

Key takeaways
  • Watch out: Row-by-row processing instead of set-based SQL.
  • Worked examples: a cds view (application modeling), set-based sql (push logic down), what it teaches.
  • How HANA examples fits into SAP development and the wider SAP landscape

A CDS view (application modeling)

define view entity Z_Sales_By_Cust as select from I_SalesOrderItem {
  key SoldToParty,
  sum( NetAmount ) as TotalNet
} group by SoldToParty

Set-based SQL (push logic down)

SELECT sold_to, SUM(net_amount) AS total
  FROM sales_items
 GROUP BY sold_to
 ORDER BY total DESC;

What it teaches

The examples embody code-to-data: aggregate and filter in the database (via CDS or SQL) rather than pulling rows into ABAP and looping. On HANA this is dramatically faster. Layer views for reuse, and push filtering/aggregation as low as possible.

Common pitfalls

  • Row-by-row processing instead of set-based SQL.
  • Pulling data out to aggregate in ABAP.
  • Monolithic views instead of layered/reusable.
