Beginner’s Guide to Using ADBC in ABAP to Connect with HANA – With Code

In today’s fast-paced digital economy, real-time data access is more crucial than ever. Businesses are transforming, and enterprise systems need to keep up. SAP HANA has emerged as a game-changer with its in-memory capabilities and lightning-fast processing speeds. But how do you harness this power from your ABAP code?

Enter ADBC (ABAP Database Connectivity) — the modern bridge between ABAP and HANA. Whether you’re an aspiring SAP developer, a business user curious about backend operations, or a professional exploring smarter integrations, this post will give you a solid starting point.

Let’s break it down in plain English — no fluff, just the essentials you need to start writing performant, HANA-optimized ABAP code using ADBC.

🌟 Why ADBC Matters in Today’s SAP Landscape

Before diving into code, let’s understand the “why”.

🚀 Market Trends

• SAP S/4HANA adoption is growing rapidly as enterprises upgrade from ECC to next-gen systems.
  
• There’s a massive demand for HANA-native ABAP skills in the job market.
  
• ADBC empowers developers to write flexible, dynamic SQL and tap into HANA features not accessible via Open SQL.
  

💡 In short: Learning ADBC isn’t just a skill boost — it’s a career investment.

🔍 What is ADBC?

ADBC (ABAP Database Connectivity) is a set of ABAP classes that allow you to execute native SQL directly on the database — in this case, HANA.

Unlike Open SQL, which abstracts away from the database, ADBC allows direct SQL execution, giving you access to advanced HANA features, better performance, and more control.

📘 Core Classes in ADBC

Class Name	Description
CL_SQL_CONNECTION	Manages the connection to the database
CL_SQL_STATEMENT	Executes SQL queries
CL_SQL_RESULT_SET	Processes results from SQL queries
CL_SQL_PREPARED_STATEMENT	Prepares parameterized SQL statements for reuse

💡 Real-World Use Case: Read Data from HANA with ADBC

Let’s say you’re working in a company using S/4HANA, and you want to retrieve sales order data in a more dynamic way than Open SQL allows. Here’s how you’d do it using ADBC.

✅ Sample Code

abap

CopyEdit

DATA: lo_sql_conn   TYPE REF TO cl_sql_connection,

      lo_sql_stmt   TYPE REF TO cl_sql_statement,

      lo_result_set TYPE REF TO cl_sql_result_set,

      lv_sql        TYPE string,

      lv_field1     TYPE string,

      lv_field2     TYPE string.

TRY.

    ” Establish database connection

    lo_sql_conn = cl_sql_connection=>get_connection( ).

    ” Create SQL statement object

    lo_sql_stmt = lo_sql_conn->create_statement( ).

    ” Define SQL query

    lv_sql = `SELECT vbeln, erdat FROM vbak WHERE erdat >= ‘20250101’`.

    ” Execute SQL query

    lo_result_set = lo_sql_stmt->execute_query( lv_sql ).

    ” Process result set

    WHILE lo_result_set->next( ) = abap_true.

      lo_result_set->get_string( EXPORTING column_index = 1 IMPORTING value = lv_field1 ).

      lo_result_set->get_string( EXPORTING column_index = 2 IMPORTING value = lv_field2 ).

      WRITE: / lv_field1, lv_field2.

    ENDWHILE.

    lo_result_set->close( ).

  CATCH cx_sql_exception INTO DATA(lx_sql).

    WRITE: / ‘SQL Exception:’, lx_sql->get_text( ).

ENDTRY.

🔎 Explanation

• We use cl_sql_connection to get a handle to the HANA DB.
  
• Then cl_sql_statement is created to define and execute raw SQL.
  
• cl_sql_result_set processes the result row by row.
  
• If any exception occurs, it’s caught and displayed.
  

🛠️ Practical Tips for Beginners

1. Validate Your SQL in HANA Studio or Eclipse before embedding it in ABAP.
   
2. Use parameterized queries via CL_SQL_PREPARED_STATEMENT to avoid SQL injection.
   
3. Keep performance in mind: avoid SELECT * and retrieve only necessary columns.
   
4. Use TRY…CATCH to handle runtime errors gracefully.
   
5. Comment your code so future developers (or you!) can understand it easily.
   

💬 Relatable Example

Imagine you’re part of the sales team, and your manager wants to see all orders from this year — but IT says it’ll take weeks to implement. With ADBC, a single ABAP report like the one above could be ready in a day — faster, leaner, and totally dynamic.

This kind of flexibility is what makes ADBC so powerful.

📈 Industry Insights: Why Companies Prefer ADBC

• Performance: Native SQL queries run faster than Open SQL in complex scenarios.
  
• Flexibility: Execute HANA-specific features like CE Functions, Calculation Views, etc.
  
• Modern Development: ADBC supports agile, test-driven development and dynamic querying.
  

Companies investing in digital transformation often expect SAP developers to be ADBC-proficient.
