PL/JSON is a generic JSON object written in PL/SQL. Using PL/SQL object syntax, users instantiate a JSON object and then add members, arrays and additional JSON objects. This object type can store JSON data, in Oracle, persistently.

What is JSON table?

JSON_TABLE is a powerful function that enables the easy decomposition of JavaScript Object Notation (JSON) data into relational format. Following these examples, database users can easily import JSON data into their relational database.

What is Oracle JSON?

Oracle Database supports JavaScript Object Notation (JSON) data natively with relational database features, including transactions, indexing, declarative querying, and views. This documentation covers the use of database languages and features to work with JSON data that is stored in Oracle Database.

Does Oracle 12c support JSON?

So for these reasons (and maybe a few more) Oracle Database 12c supports JSON natively with relational database features, including transactions, indexing, declarative querying, and views. Oracle Database queries are declarative, so you can join JSON data with relational data.

Is JSON strict Oracle?

5.2 About Strict and Lax JSON Syntax. The Oracle default syntax for JSON is lax. Oracle supports this strict JSON syntax, but it is not the default syntax. In JavaScript notation, a field used in an object literal can be, but need not be, enclosed in double quotation marks.

What is a JSON CLOB?

You can store JSON data in Oracle Database using columns whose data types are VARCHAR2 , CLOB , or BLOB . Use BLOB (binary large object) or CLOB (character large object) storage if you know that you have some JSON documents that are larger than 32767 bytes (or characters)Footref 1.

What is the structure of a JSON file?

JSON defines only two data structures: objects and arrays. An object is a set of name-value pairs, and an array is a list of values. JSON defines seven value types: string, number, object, array, true, false, and null. The following example shows JSON data for a sample object that contains name-value pairs.

How does a JSON file work?

JavaScript Object Notation (JSON) is a way of storing information in an organized and easy manner. The data must be in the form of a text when exchanging between a browser and a server. You can convert any JavaScript object into JSON and send JSON to the server.

Can we store JSON in CLOB?

JSON can be stored as VARCHAR2 (up to 32767 bytes), CLOB and BLOB. CLOB and BLOB have no length limitations.

How to parse a JSON table in SQL?

You can use JSON_TABLE () function within Oracle’s SQL containing a CROSS JOIN in order to parse individual column values for product and fcode, and use them in SELECT-list and WHERE condition, respectively as below :

How to use PL / SQL Object Types for JSON?

Some examples of using PL/SQL object types for JSON are presented. Example 21-1 Constructing and Serializing an In-Memory JSON Object This example uses function parse to parse a string of JSON data that represents a JSON object with one field, name, creating an instance je of object type JSON_ELEMENT_T.

How to transform JSON into rows in SQL Server?

After you transform a JSON collection into a rowset with OPENJSON, you can run any SQL query on the returned data or insert it into a SQL Server table. The OPENJSON function takes a single JSON object or a collection of JSON objects and transforms them into one or more rows. By default, the OPENJSON function returns the following data:

Where is JSON data stored in Oracle Database?

You can even query, right from within the database, JSON data that is stored outside Oracle Database in an external table. Oracle’s Live SQL provides developers a free and easy online way to test and share SQL and PL/SQL application development concepts.
