I have created this query in repository with appropriate java class for projection. When query is executed, i am getting null in walmartYearWeek.
@Query("""
SELECT DISTINCT ON (com_yr_wk) com_yr_wk as walmart_year_week, com_start_date as walmart_week_start_date
FROM calendar_meta
WHERE calendar_date BETWEEN :startDate AND :endDate
ORDER BY com_yr_wk
""")
Flux<WalmartCalendarWeek> findWalmartYearWeekDistinctByDateBetween(LocalDate startDate, LocalDate endDate);
@Data
@AllArgsConstructor
@NoArgsConstructor
public class WalmartCalendarWeek {
Integer walmartYearWeek;
LocalDate walmartWeekStartDate;
}
Then, i tried following query and class and now the value is coming as expected in walmarYearWeek.

Flux<WalmarCalendarWeek> findWalmarYearWeekDistinctByDateBetween(LocalDate startDate, LocalDate endDate);
@Data

public class WalmarCalendarWeek {
Integer walmarYearWeek;
LocalDate walmartWeekStartDate;
}
To conclude, walmart_year_week alias is not working but walmar_year_week or any other alias works
NOTE: Above issue is not there with org.springframework.boot:spring-boot-starter-parent:3.2.0.
