What reasons might hinder the use of native SQL queries within the current project?

Reasons that may prevent the use of native SQL queries in a Java project include:

• Use of ORM (e.g., Hibernate), which abstracts database interactions and allows writing queries in object-oriented language.
• Security requirements: native SQL queries can be vulnerable to SQL injection if prepared statements are not used.
• Support for different DBMS: ORM and other abstractions make it easier to switch databases without rewriting queries.
• Complexity and scale of the project: in large projects, native queries can complicate maintenance and testing.

Therefore, the choice to avoid native SQL queries is often related to increasing security, ease of maintenance, and portability of the code.
