This means that developers can use JSON data as input and output parameters in their database programs. Oracle PL/SQL also provides support for JSON in stored procedures, triggers, and functions. ![]() ![]() This code creates a JSON object with the keys “name” and “age” and their corresponding values and then prints the resulting JSON string to the console. Here is an example of using the JSON_OBJECT function to generate a JSON object from a set of key-value pairs: DECLAREĭBMS_OUTPUT.PUT_LINE(l_json_object.TO_STRING()) JSONQUERYARRAY, Extracts an array of JSON values, such as arrays or objects, and JSON scalar. This example iterates through the fields returned by getkeys (), adding them to an instance. Returns a SQL NULL if a non-scalar value is selected. The varray contains all of the field names for the given JSONOBJECTT instance. It returns an instance of PL/SQL object type JSONKEYLIST, which is a varray of VARCHAR2 (4000). For example, you can retrieve JSON data from a web service, parse it using the JSON functions, and then insert it into an Oracle database table. PL/SQL method getkeys () is defined for PL/SQL object type JSONOBJECTT. Using these functions, you can easily work with JSON data in your PL/SQL applications. JSON_ARRAY: This function generates a JSON array from a set of values. JSON_OBJECT: This function generates a JSON object from a set of key-value pairs. JSON_TABLE: This function converts a JSON document into a relational table. JSON (JavaScript Object Notation) is a lightweight data format that is. JSON_QUERY: This function extracts a JSON object or array from a JSON document. One of the many features of Oracle PL/SQL is its support for working with JSON data. JSON_VALUE: This function extracts a scalar value from a JSON document. The JSON functions in PL/SQL include functions for parsing JSON data into PL/SQL data structures and for generating JSON data from PL/SQL data structures. In Oracle PL/SQL, you can use the built-in JSON functions to parse and generate JSON data. It has become a popular format for exchanging data between web applications and is often used for storing and retrieving data in NoSQL databases. JSON (JavaScript Object Notation) is a lightweight data format that is easy for developers to read and write and easy for machines to parse and generate. One of the many features of Oracle PL/SQL is its support for working with JSON data. Function jsonmergepatch can accept as input, and return as output, any SQL data type that supports JSON data: JSON, VARCHAR2, CLOB, or BLOB. ![]()
