Convert JSON string to JSONB

问题

I have a table with jsonb field. Some of the rows are an array of objects, but some of the others are string.

I want to convert red rows to array of objects.

My table structure:

How I can do this in PostgreSQL?

回答1:

Following SQL should do the trick:

update your_table_name 
set content =  (content#>>'{}')::jsonb 
where jsonb_typeof(content)='string';
