Here are functions to serialize/unserialize a table or object (usually, not. Style of table construction?), binary I/O, XML, JSON, YAML, HTML,. Have you googled how to build a table from json using jQuery?

Oracle SQL function
json_serialize
takes JSON data (of any SQL data type, VARCHAR2
, CLOB
, or BLOB
) as input and returns a textual representation of it. You typically use
json_serialize
to transform the result of a query. It supports an error clause and a returning clause. You can specify pretty-printing for the result, and you can truncate the result to fit the return type. Function
json_serialize
always produces JSON data that conforms to the JSON standard (RFC 4627). The returned data uses only the standard data types of the JSON language: object, array, and the scalar types string, number, Boolean, and null. You can use
json_serialize
to convert binary JSON data to textual form (CLOB
or VARCHAR2
), or to transform textual JSON data by pretty-printing it or escaping non-ASCII Unicode characters in it. An important use case is serializing JSON data that is stored in a BLOB
column. A BLOB
result is in the AL32UTF8 character set. But whatever the data type returned by json_serialize
, the returned data represents textual JSON data. See Also:

json_serialize
Example 19-1 Using JSON_SERIALIZE To Convert BLOB Data To Pretty-Printed Text
This example serializes and pretty-prints the JSON purchase order that has
1600
as the value of field PONumber
data, which is selected from column po_document
of table j_purchaseorder
The return-value data type is VARCHAR2(4000)
(the default return type). Example 4-2 shows the insertion of such purchase-order data into a
VARCHAR2
table. But json_serialize
is especially useful for serializing BLOB
data. See Example 9-1 for how to create a table with a BLOB
column of JSON data. Related Topics

This article is about DataContractJsonSerializer. For most scenarios that involve serializing and deserializing JSON, we recommend the APIs in the System.Text.Json namespace.
JSON (JavaScript Object Notation) is an efficient data encoding format that enables fast exchanges of small amounts of data between client browsers and AJAX-enabled Web services.
This article demonstrates how to serialize .NET type objects into JSON-encoded data and then deserialize data in the JSON format back into instances of .NET types. This example uses a data contract to demonstrate serialization and deserialization of a user-defined
Person
type and uses DataContractJsonSerializer.Normally, JSON serialization and deserialization are handled automatically by Windows Communication Foundation (WCF) when you use data contract types in service operations that are exposed over AJAX-enabled endpoints. However, in some cases you may need to work with JSON data directly.
This article is based on the DataContractJsonSerializer sample.
To define the data contract for a Person type
- Define the data contract for
Person
by attaching the DataContractAttribute to the class and DataMemberAttribute attribute to the members you want to serialize. For more information about data contracts, see Designing service contracts.
To serialize an instance of type Person to JSON
Note
If an error occurs during serialization of an outgoing reply on the server or for some other reason, it may not get returned to the client as a fault.
- Create an instance of the
Person
type. - Serialize the
Person
object to a memory stream by using the DataContractJsonSerializer. - Use the WriteObject method to write JSON data to the stream.
- Show the JSON output.
To deserialize an instance of type Person from JSON
- Deserialize the JSON-encoded data into a new instance of
Person
by using the ReadObject method of the DataContractJsonSerializer. - Show the results.
Example
Note
The JSON serializer throws a serialization exception for data contracts that have multiple members with the same name, as shown in the following sample code.
