Understanding JPQL and SQL Queries JPQL (Java Persistence Query Language) is a query language used to retrieve data from a database in Java-based applications. It’s similar to SQL (Structured Query Language), but with some key differences. SQL queries typically operate on specific tables or views, using keywords like SELECT, FROM, and WHERE. JPQL, on the other hand, allows for more dynamic querying, enabling developers to fetch data based on various criteria, such as relationships between entities or values within arrays.
