How to update jsonb string with postgresql?

@ryleigh 

To update a JSONB column in PostgreSQL, you can use the jsonb_set function. Here's an example of how to update a JSONB column called data in a table called my_table:

1
2
3

UPDATE my_table
SET data = jsonb_set(data, '{key1}', '"new_value"', true)
WHERE condition;

In this example:

• data is the name of the JSONB column you want to update
• {key1} is the path to the key you want to update within the JSONB column
• "new_value" is the new value you want to set
• true indicates that the function should create any missing keys along the path

Make sure to replace my_table with the actual name of your table, and adjust the WHERE condition as needed to specify which rows you want to update.
