Which tools can provide input data for the SQL performance tuning work list (Transaction SWLT)?

ABAP test cockpit (transaction ATC)

Code inspector (transaction SCI)

SQL Trace (transaction ST05)

All of the above

The SQL performance tuning work list in transaction SWLT is designed to help developers optimize their SQL statements in SAP HANA. This tool consolidates various analyses and improvements that can be made to enhance the performance of SQL queries.

Each of the mentioned tools plays a significant role in identifying potential performance issues and providing useful data for SQL tuning:

1. **ABAP test cockpit (transaction ATC)**: This tool is used to perform static code checks in ABAP programs. It helps identify potential performance issues in ABAP code that may impact database operations, thus providing valuable insights into how the SQL generated from ABAP can be optimized.

2. **Code inspector (transaction SCI)**: Similar to the ATC, the Code Inspector assesses the quality of ABAP code, including performance checks. By analyzing the ABAP source code for best practices and optimization opportunities, it can highlight specific areas that may generate inefficient SQL statements.

3. **SQL Trace (transaction ST05)**: This trace tool is specifically designed to monitor and analyze the performance of SQL statements. By tracking database requests and execution times, it delivers detailed performance metrics, making it an essential input for the SWLT when identifying slow-running queries or those consuming excessive resources.

Since all three tools provide critical
