HQL (Hibernate Query Language) does not provide a built-in function called `to_date` like SQL does. However, you can still achieve the same functionality using other HQL functions and expressions.
If you want to convert a string to a date in HQL, you can use the `cast` function to explicitly cast the string to a date type. Here's an example:
```java
String hqlQuery = "SELECT e FROM Employee e WHERE e.hireDate >= cast(:startDate as date)";
Query query = session.createQuery(hqlQuery);
query.setParameter("startDate", "2022-01-01");
List<Employee> result = query.getResultList();
```
In this example, we are casting the `startDate` parameter from a string to a date type using the `cast` function. Then, we can use this date value in the HQL query to filter employees based on their hire dates.
Keep in mind that the syntax and available functions may vary depending on the specific version of Hibernate you are using.
