Table

Input Table (required) |
The name of the input table you want to load to the database. |
| DB Table Name (required) | The name of the table that will be created in the database. |
| Export (optional) | True if you want this table to be loaded or not. By default, it is true. |

|
| Column (required) |
Can be defined for table either when using incremental load, or not.
Primary key constraint can be defined on multiple columns or one, but cannot contain NULL values. If incremental load is enabled, then only rows with new or updated records are inserted.
