+/**
+ * The {@code SQL} annotation is a custom annotation used to associate SQL query strings
+ * with methods or elements in your code.
+ * <p>
+ * When applied to a method, field, or other element, this annotation provides a convenient
+ * way to specify an SQL query that should be associated with that element.
+ * </p>
+ * <p>
+ * For example, you can use this annotation to specify a SQL query for a method as follows:
+ * </p>
+ * <pre>
+ * {@code
+ * @SQL("SELECT * FROM users WHERE status = 'active'")
+ * public void getUserData() {
+ *     // Method implementation
+ * }
+ * }
+ * </pre>
+ * <p>
+ * In the context of an {@code OracleRepository}, you can use the {@code @SQL} annotation
+ * to define custom SQL queries for repository methods. Here's an example:
+ * </p>
+ * <pre>
+ * {@code
+ * public interface UserRepository extends OracleRepository<User, Long> {
+ *     // Find all active users using a custom SQL query
+ *     @SQL("SELECT * FROM users WHERE status = 'active'")
+ *     List<User> findActiveUsers();
+ * }
+ * }
+ * </pre>
+ * <p>
+ * In this example, the {@code @SQL} annotation is used to define a custom SQL query for the
+ * {@code findActiveUsers} method in an {@code OracleRepository} interface, allowing you
+ * to execute the specified SQL query when calling the repository method.
+ * </p>
