How do I return a set of jsonb objects

In order to return a set of JSONB objects from a PostgreSQL database, you can use the jsonb_agg() function, which is used to aggregate multiple JSONB objects into a single JSONB array.

Here’s an example of how you can use the jsonb_agg() function to return a set of JSONB objects from a table called “mytable”:

SELECT jsonb_agg(jsonb_column) FROM mytable;

In this example, the jsonb_agg() function is used to aggregate all the values in the jsonb_column column of the “mytable” table into a single JSONB array.

You can also use the GROUP BY clause to group the results by a certain column, and return a set of JSONB objects for each group. Here’s an example:

SELECT group_column, jsonb_agg(jsonb_column) FROM mytable GROUP BY group_column;

In this example, the jsonb_agg() function is used to aggregate all the values in the jsonb_column column of the “mytable” table into a single JSONB array for each group defined by group_column.

It’s important to note that the jsonb_agg() function is specific to PostgreSQL, and it may not be available in other database management systems.

It’s also important to keep in mind that PostgreSQL has a limit of 1GB for the jsonb data type, so you should be careful when using this function with large amounts of data.
