Which three data file formats can be loaded using oracle database actions?
Oracle Database Actions provides a web-based interface with development tools, data tool, administration, and monitoring features and lets you load or access data from local files, from cloud storage, or from remote databases. Show
On the Database Actions Data Load page you can choose to load data from a file on your local device, from cloud storage, or from a database. You can also choose to explore the data in your Oracle Autonomous Database. See The Data Load Page for detailed information and the steps for loading data using Database Actions. Description of the illustration database_actions_load_data.png See Connect with Built-in Oracle Database Actions for information on accessing Oracle Database Actions. The values you provide for CREATE TABLE CHANNELS (channel_id CHAR(1), channel_desc VARCHAR2(20), channel_class VARCHAR2(20) ); /6 and CREATE TABLE CHANNELS (channel_id CHAR(1), channel_desc VARCHAR2(20), channel_class VARCHAR2(20) ); /7 depend on the Cloud Object Storage service you are using:
This operation stores the credentials in the database in an encrypted format. You can use any name for the credential name. Note that this step is required only once unless your object store credentials change. Once you store the credentials you can then use the same credential name for all data loads.

Each value, each line, is loaded into a collection on your Autonomous Database as a single document. Here is an example of such a file. It has three lines, with one object per line. Each of those objects gets loaded as a separate JSON document. { "name" : "apple", "count": 20 } { "name" : "orange", "count": 42 } { "name" : "pear", "count": 10 } Procedure:

Query these tables to see information about ongoing and completed data loads. For example, using a 4 statement with a 5 clause predicate on the 6 column, shows load operations with the type 7:
The 8 column shows the name of the table you can query to look at the log of a load operation. For example, the following query shows the log of the load operation:select * from COPY$21_LOG; The 9 column shows the name of the table you can query to look at the rows that got errors during loading. For example, the following query shows the rejected records for the load operation:
