PostgreSQL provides two native operators -> and -> to help you query JSON data. For more examples and JSON functions and operators refer to the official PostgreSQL documentation. PostgreSQL returns a result set in the form of JSON. All this brings us advantages when combining it with the practicality of a NoSQL document-oriented solution, but still using the powerfull features of a RDBMS. I mean, if jsonb extends the capabilities of json, then would it be safe to make an alert and have the field type from json to jsonb postgresql. ![]() I checked json and jsonb operators, and saw that jsonb doesnt have any operators that json doesnt have. The features jsonb column type brings are so powerful that afford you to handle any document-oriented data structures very well and on the other side with a very significant gain in performance. 2 days ago &0183 &32 I found a solution where they say to replace json fields with jsonb to solve this problem. Yes, jsonb operators are powerful combined with SQL. This query renames FirstName to Name, by removing FirstName and adding Name with preset value from FirstName. SET data = data - 'FirstName' || jsonb_build_object( 'Name', data-> 'FirstName') This query deletes the third element from Items array. This query removes City field from Address nested object. PRODUCTS: inserting some data INSERT INTO products (DATA) VALUES ( Next, let's add sample data with which we will work with. In these examples we use the familiar model with users, orders and products tables. Introductionīefore we get started, let's get familiar with the sample structure we'll use in this example series. To fully understand the design of jsonb data type and what you can do with it, check the official documentation on JSON Types and JSON Functions and Operators. This article demonstrates usage of jsonb operations and storage mechanics. ![]() On the other hand it is significantly faster to process, since no reparsing is needed and supports indexing, which can be of a serious advantage. This makes it slightly slower to input due to added conversion overhead and might take more disk space to store. PostgreSQL in version 9.4 introduced jsonb, a new column type for storing documents in binary JSON format.
