SAP / SAP Beginner (0 to 2 yrs) Interview questions

What is the difference between Open SQL and Native SQL?

Open SQL is ABAP's portable, database-independent SQL subset, processed through ABAP's own database interface. Native SQL (accessed via EXEC SQL ... ENDEXEC, or ADBC for object-oriented access) passes SQL statements directly to the underlying database in its own native dialect, bypassing ABAP's abstraction layer entirely.

Open SQLNative SQL
Database-independent; same code works across supported databases. Tied to the specific database's own SQL dialect and features.
Integrates with SAP authorization checks and buffering. Bypasses SAP's abstraction layer entirely.
Recommended default for almost all ABAP development. Reserved for rare cases needing a database-specific feature Open SQL doesn't expose.

Because Native SQL locks a program to one specific database, it's used sparingly and only when a genuine need for a database-specific capability outweighs the portability Open SQL provides.

What does Native SQL bypass that Open SQL does not?
Why is Native SQL used sparingly in ABAP development?
