What is the impact of using ORDER BY clauses in a native SQL statement on SAP HANA?

Using ORDER BY clauses in a native SQL statement on SAP HANA is significant primarily due to its potential compatibility issues. In SAP HANA, when a query with an ORDER BY clause is executed, the database must ensure that the results are returned in the specified order. This can have an impact on how different database systems process SQL commands, especially if those systems have variations in implementation or do not support certain ordering mechanisms as effectively.

While the ORDER BY clause is essential for ensuring that results are presented in a user-defined sequence, its introduction can lead to inconsistencies or complications when attempting to share queries across multiple database environments. This is particularly true when porting SQL code from one system to another, where different databases may have different optimization strategies or interpretations of the SQL standard.

Also, using ORDER BY may affect performance in scenarios where large datasets are involved, as sorting the data requires additional processing time. This means that while it serves its purpose in presenting data, it comes with considerations that developers need to be aware of regarding compatibility across different systems.

In contrast, improvements in performance, guaranteed data consistency, and enhancements in query readability are not inherently tied to the use of ORDER BY. While it may make queries more readable by providing a structured output, this
