In SAP, ADBC stands for ABAP Database Connectivity. It is a class-based API that allows ABAP programs to directly execute Native SQL statements on the underlying database.
🔎 What ADBC Is
- Definition: ABAP Database Connectivity (ADBC) is a modern interface in SAP that provides direct access from ABAP code to the database using SQL.
- Purpose: It bridges ABAP applications with databases like SAP HANA, enabling developers to run complex queries and leverage advanced database features.
- Type of API: Class-based, meaning it uses ABAP Objects (OO) rather than traditional procedural calls.
⚙️ Key Features
- Direct SQL Execution: Developers can run SQL statements (SELECT, INSERT, UPDATE, DELETE) directly from ABAP without going through Open SQL.
- Performance: Optimized for SAP HANA’s in-memory computing, allowing faster data retrieval and manipulation.
- Flexibility: Supports database-specific features that are not available in standard Open SQL.
- Integration: Useful when ABAP applications need to interact with external or advanced database functions.
📌 Example Usage
A typical ADBC workflow in ABAP involves:
- Creating a connection to the database using
CL_SQL_CONNECTION. - Preparing a statement with
CL_SQL_STATEMENT. - Executing the query and fetching results with
CL_SQL_RESULT_SET.
DATA: lo_con TYPE REF TO cl_sql_connection, lo_stmt TYPE REF TO cl_sql_statement, lo_res TYPE REF TO cl_sql_result_set. lo_con = cl_sql_connection=>get_connection( ). lo_stmt = lo_con->create_statement( ). lo_res = lo_stmt->execute_query( 'SELECT * FROM my_table' ).
🚀 Why It Matters
- For Developers: ADBC provides more control and efficiency when working with large datasets or advanced database features.
- For Businesses: It enables real-time analytics and faster application performance, especially critical in SAP HANA environments.
