Steps to Update a JSONB Field Value in PostgreSQL

Using the jsonb data type, we can store JSON data in an organized manner. We can use the UPDATE statement in conjunction with different PostgreSQL JSON functions in order to update the value of a particular field within JSON data in a table that has a jsonb column. Let’s see the steps to change the value of a JSONB column in PostgreSQL:

1. To change a JSONB field, we must first locate the row in the database that contains the field. To define the condition that matches the row or rows we need to update, we usually use a WHERE clause.

2. We can change the JSONB data within the UPDATE statement using PostgreSQL’s JSON functions. Among the frequently used functions are jsonb_set, jsonb_insert, and jsonb_delete.

3. To apply the changes to the database, we have to run the UPDATE statement after creating it with the necessary JSON functions.

An Example

To show how to edit a jsonb field value in PostgreSQL, consider the following example. Suppose we have a data column of type jsonb in a database named Fruits. We would want to change the cost field for a Fruit whose ID is equal to 1:

Within a JSONB document, the PostgreSQL function jsonb_set sets a JSONB value at a given path. The cost field’s value is being set to “750” in this case. The JSONB data’s id field’s value is extracted with the command data->>’id’. WHERE the condition to find the row where the id equals one is data->>’id’ = ‘1’. The cost field in the data column for the Fruit whose id is equal to 1 will update to 750 following the running of this SQL statement.
