Explore Open SQL subqueries and exists in ABAP, using outer and inner selects, aliases, and conditional filtering to retrieve purchase order headers by org values and plant.

Explore open SQL intermediate techniques: insert from a subquery with a 7.5x index, inner join purchase order and org tables, and aggregate net price by plant and currency.

Explore the theory of three join types—inner, left outer, and right outer—using a paired table example to show how matches determine results, blanks when no match, and join priorities.

Demonstrates open sql advanced joins using left outer and right outer joins between Z head and Z org, contrasts inner joins, and shows handling of missing purchase document values.

Use cross joins to generate the cross product of table rows; beware of large data sets, filter with where, limit results, and note order by restrictions and table buffer behavior.

Master open sql union with select in sap abap, merge results from multiple selects with union or union all, ensure column names and types, and use hyphen for missing values.

Learn how sql expressions enable arithmetic, string, and case expressions on the database to optimize ABAP applications, transforming internal tables and improving performance through database-level calculations including scale.
