![]() I tend to query JSON from our API_STAGING table. Go pull data from there with your browser, cURL, Postman or something. You can fetch some JSON data at the following links:Īnd if you are reading this article, then you likely have an API target selected. Sometimes even the process of pasting to a text-based note pad then copying won’t avoid these problems. Most of us that attend “Internet University” have experienced copying text from a website only to find unprintable (hidden) ASCII characters that waste an hour of troubleshooting. Additionally, creating JSON data from a blog post may introduce an error that will be impossible to find. Finding interesting JSON data on the web is easier than creating JSON data. Nearly all of the Oracle documentation, guidance, and related blog posts start with the awkward premise of populating the data. APEX Debug Messages – standardizing error collection, debugging, and trace. ![]() This article is part of a series of articles about developing an API with Oracle PL/SQL and Oracle APEX. In an effort to provide a single point of reference, I’ll touch on resources that permit hosting your own data in a RESTful format for others to perform a GET. I write with a slight bias that involves fetching data via a RESTful GET. RESTful API development and rapid parsing of JSON data must travel hand-in-hand. Instead, I indent to increase parity between the JSON datatype support with the increasing support of RESTful API. Publishing a blog about this in 2021 does not push the envelop on early adoption of technology. With Oracle 12c, the support for native JSON improved. One can observe a trend at Oracle that continues to include JSON as an important and ongoing source of data. Reducing code with the select statement reduces the risk of errors and reduces the cost of developing API. When I compare an older API I wrote in PLSQL using these apex_json functions to the current technique involving the select statement, we reduce the amount of code needed by 75%. Years ago, we relied on parsing the data with APEX functions such as apex_json.parse and apex_json.get_varchar2. Parsing JSON data may be accomplished within an Oracle select statement. ![]() Oracle Native JSON, Oracle JSON_TABLE, Oracle apex_json, plsql, plsql api, Restful API Introduction and History This is part of a series of articles on developing and supporting API written with Oracle PL/SQL and Oracle APEX. You’ll need to utilize these skills while developing Application Programming Interfaces (API). We will explore SQL select statements to parse JSON data including arrays. Querying JSON successfully relies on more than knowing syntax, but also understanding how the data structures differ. JSON often contains arrays of data within elements. ![]() For nearly 50 years, Oracle has been a relational database relying on linking data between tables. Querying JSON data within Oracle improves year by year. ![]()
