![]() In SQL Server 2017 (14.x) and in Azure SQL Database, you can provide a variable as the value of path. I quote Andrew Dunstan on the pgsql-hackers list: At some stage there will possibly be some json-processing (as opposed to json-producing). Then, you can filter on column locale in the generated records, and finally recompose a new json object with your expected result: select jsonbuildobject ('description', d.content) hoteldatadescrfr from mytable, jsontorecordset (hoteldata. 1 I would like to get the output of a particular Query from the postgresql server having joins of a multiple Tables with one to many relations in the json format to a particular file. A JSON path that specifies the object or the array to extract. When you use the JSONB format, the data is. The recommended type is JSONB for almost all cases. Use the -> operator and the SQL WHERE clause. You can use a lateral join and jsontorecordset to expand the json array as a set of records. PostgreSQL supports two types of JSON columns: JSON and JSONB. Jsonb_path_query(payload, '$.**. Query the PostgreSQL JSON Columns Use the -> operator to get a specific JSON object field. Postgres has two data types for this purpose. Because the -> operator returns an object, you can chain it to inspect deep into a JSON document. These operators work on both JSON as well as JSONB columns. The first operator -> returns a JSON object, while the operator -> returns text. PostgreSQL JSON Data Types As I mentioned previously Postgres has built-in support for JSON so we wont be storing the data as raw text. PostgreSQL has two native operators -> and -> to query JSON documents. This is what I was trying, but doesn't work to remove quotes from Text value and gives an error on numeric Select Finally, Postgres has built-in support for querying and processing JSON data natively. ![]() ![]() Is it possible to do it this way or must I use the -> and -> for each node in the path ? This will make the query look complicated as I have to select about 35+ attributes in the select with quite deep paths.Īlso, how do we remove quotes from the selected value? In PostgreSQL using jsonb column, is there a way to select / convert an attribute with actual datatype the datatype instead of getting it as a string object when using jsonpath? I would like to try to avoid cast as well as -> and -> type of construct since I have to select many attributes with very deep paths, I am trying to do it using jsonpath and * or ** in the path
