Use the INSERT statement to add rows to the database. Because the import data for your destination table is included in the INSERT statement, it is considered interactive input. You can also use the INSERT statement with remote data access to import data from another database rather than a file.
Use the INSERT statement to import data when you:
want to import small amounts of data into a single table
are flexible with your file formats
want to import remote data from an external database rather than from a file
The INSERT statement provides an ON EXISTING clause to specify the action to take if a row you are inserting is already found in the destination table. However, if you anticipate many rows qualifying for the ON EXISTING condition, consider using the MERGE statement instead. The MERGE statement provides more control over the actions you can take for matching rows. It also provides a more sophisticated syntax for defining what constitutes a match.
