Spring-Data-JPA native query on jsonb field - postgresql

Question

Given the following JSON which is stored as jsonb in a postgres table:
{
"object" : {
"array" [
{
"uuid" : "34ad3558-a3e7-43d0-826f-afddce255b20"
}
]
}
}
I have a working query to search if a field value is present within the JSON document:
select * from my_table
where my_json#>'{"object": {"array" : [{"field": "34ad3558-a3e7-43d0-
826f-afddce255b20"}]}}';
However when I try to replicate this query in Spring-Data-JPA using a native query on a JPARepository I keep getting the following exception:
org.springframework.dao.InvalidDataAccessApiUsageException: Parameter with that position [1] did not exist
I initally tried:
#Query(value = "Select * From my_table"
+ "and my_json#>'{\"object\": {\"array\" : [{\"uuid\": \"?1\"}]}}'",
nativeQuery = true)
Set<MyEntity> myQuery(UUID uuid);
Following this I tried binding the parameter with #Param :
#Query(value = "Select * From my_table"
+ "and my_json#>'{\"object\"\\: {\"array\" \\: [{\"uuid\"\\: \":uuid\"}]}}'",
nativeQuery = true)
Set<MyEntity> myQuery(#Param("uuid") UUID uuid);
After that I tried converting the UUID to a String:
#Query(value = "Select * From my_table"
+ "and my_json#>'{\"object\"\\: {\"array\" \\: [{\"uuid\"\\: \":uuid\"}]}}'",
nativeQuery = true)
Set<MyEntity> myQuery(#Param("uuid") String uuid);
Still nothing works. The JPA entity looks like this :
#Entity
public class MyEntity {
#Id
private long id;
#Column("my_json")
private MyJson myJson
}
Other queries that invole the entity work fine with the jsonb field binding to MyJson entity. Is there a way to make this work?

Answer 1

You have to cast the value in your native query.
cast(:uuid as UUID)
So your query becomes.
#Query(value = "Select * From my_table"
+ "and my_json#>'{\"object\"\\: {\"array\" \\: [{\"uuid\"\\: cast(:uuid as UUID)}]}}'",
nativeQuery = true)
