To see the difference between those operators, please check the Postgres documentation linked earlier. The jsonb_extract_path and jsonb_extract_path_text are wrappers for #> and #> operators. Why Use the posjsonhelper Library When Hibernate Has Some Support for JSON Attributes Queryīesides those two operators that support the array types mentioned above, the library has two additional useful operators.
POSTGRES JSONB QUERY HOW TO
Jsonb_any_array_strings_exist(jsonb_extract_path(i1_0.jsonb_content,?),array)įor more examples of how to use numeric operators please check the demo dao object and dao tests. For the default setting these functions will have the implementation below. Posjsonhelper the library requires two custom SQL functions that will wrap those operators. That is why we need to wrap them, for example, in a custom SQL function. The operator above can not be used in HQL because of special characters. So generally if we have a JSON property that contains an array, then you can check if it contains the least of the elements that you are searching by.īesides executing native SQL queries, Hibernate 6 does not have support for the above operations. ?| - This checks if any of the strings in the text array exist as top-level keys or array elements.So generally if we have a JSON property that contains an array, then you can check if it contains all elements that you are searching by. ?&- This checks if all of the strings in the text array exist as top-level keys or array elements.The library supports a few Postgres JSON function operators, such as: The jsonb_extract_path_text is a Postgres function that is equivalent to the #> operator (please check the Postgres documentation linked earlier for more details). Jsonb_extract_path_text(i1_0.jsonb_content,?) like ? escape '' Public List findAllByStringValueAndLikeOperatorWithHQLQuery(String expression) ') īelow is an example of the same query presented at the beginning, but created with SQM components and criteria builder:
