Note
- For tabular formats (CSV, TSV, PSV), you can't map a column twice. To map to an existing column, first delete the new column.
- You can't change an existing column type. If you try to map to a column having a different format, you may end up with empty columns.
The changes you can make in a table depend on the following parameters:
- Table type is new or existing
- Mapping type is new or existing
| Table type | Mapping type | Available adjustments |
|---|---|---|
| New table | New mapping | Rename column, change data type, change data source, mapping transformation, add column, delete column |
| Existing table | New mapping | Add column (on which you can then change data type, rename, and update) |
| Existing table | Existing mapping | none |
