Nesting Json Functions Inside Json Arrayagg And Json Objectagg In Ben nadel demonstrates that json functions can be nested inside json arrayagg () and json objectagg () aggregation functions in mysql 5.7.38. I use json extract to convert the string to json. so we have several conversions: json to string to json. select json arrayagg( json object( 'uuid', uuidfrombin(staff.uuid), 'username', staff.username, 'name', staff.name, 'surname', staff.surname, 'skills', json extract( (select json arrayagg( json object( 'uuid', uuidfrombin(s.uuid), 'name', s.

Sql Server Json Functions Json Objectagg And Json Arrayagg Mssqltips I'm struggling trying to aggregate results in a table into a nested json. this is the table: | id | area | userid | game | st. Two new t sql functions have been introduced to create json artifacts from your data: json objectagg and json arrayagg. both are aggregation functions and help you create json statements from data that is stored in multiple rows. in this tip, we’ll give you an introduction to both functions. Nested json arrayagg is not allowed instead you have to use nested query. i have modified your query following should work. jrt.threadid, json arrayagg( json object( 'roundid',jrr.roundid, 'bets',( select json arrayagg( json object( 'betid', bets.betid, 'amount', bets.amount. ) from threads jrt. left join rounds jrr on jrt.threadid = jrr.threadid. Consider following two tables in mysql database. and a pivot table. i can extract a single role in json format using the following query. 'id', r.role uuid, 'tasks', (select json arrayagg( json object( 'id', t.task id. )) from role r. inner join role task rt on r.role id = rt.role id. inner join task t on rt.task id = t.task id.

F1: the window functions should have the similar semantics as the grouped aggregates json arrayagg and json objectagg, that is to combine json documents in multiple rows into a json array or a json object respectively. The json arrayagg () and json objectagg () then take those results and roll them up into a single value per grouping (as an array literal or object literal, respectively). The json arrayagg() function gathers all the values in a given column and returns then in a single, aggregated json array. the json objectagg() function allows us to gather data from two columns and returns them in a single, aggregated json object. Select json object( key 'foo' value json arrayagg((select * from dual)), key 'nested' value (select json object(key 'bar' value 2) from dual) ) from dual; try to comment out either foo or nested and see that running either alone will work, but as written above running it gives:.
