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 SQL | Native 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.
