Which procedure can be used to load data directly into existing ADB tables?

The procedure that can be used to load data directly into existing ADB tables is DBMS_CLOUD.COPY_DATA. This procedure is specifically designed for copying data from an external data source into an existing table in Oracle's Autonomous Database (ADB). It's particularly useful when integrating data from external locations, such as cloud storage.

When using DBMS_CLOUD.COPY_DATA, you can specify the external cloud storage location (like an Amazon S3 bucket or Oracle Cloud Object Storage) from which you want to import data. The procedure facilitates the loading process by allowing you to define various options such as file format and mapping fields from the source to the destination table. This makes it an efficient and practical choice for data ingestion.

The other options serve different purposes:

• DBMS_CLOUD.LIST_FILES is used to list the files in an external file location, which doesn't involve loading data.

• DBMS_CLOUD.CREATE_EXTERNAL_TABLE is designed to create an external table that can reference data outside of ADB without loading it into the database.

• DBMS_CLOUD.PUT_OBJECT is for uploading files to Cloud Object Storage but does not directly load data into ADB tables.

Understanding each of these procedures and their specific roles can help in identifying the most appropriate
