The column values returned by the subquery are assigned to the columns in the column list in order. WHERE search_condition Chooses which rows to update in the database table.
The first value is assigned to the first column in the list, the second value is assigned to the second column in the list, and so on. Only rows that meet the search condition are updated.

These paths are used frequently in a variety of front-end development and QA automation tasks.

You will need to tell DBD that you are inserting a LOB, similar to this: While this seems trivial, if you ever put something like a frozen data structure (via the Freeze Thaw module) in a CLOB, you'll end up getting errors all over the place when you later try to thaw it if the frozen structure happens to have whitespace at the end.It lets you create and store collections of documents of any kind (not just JSON), retrieve them, and query them, without needing to know how the documents are stored in the database.SODA also provides query features that are specific for JSON documents.Each file can be exposed to Oracle Database as a row in an external table.
