Changes to System Behavior
SOURCEROWNUMBER function generates null values consistently
The SOURCEROWNUMBER function returns the row number of the row as it appears in the original dataset. After some operations, such as unions, joins, and aggregations, this row information is no longer available.
Previously, the results were confusing. When source row information was not available, the function was simply not available for use.
Now, the behavior of the SOURCEROWNUMBER function is more consistent:
- If the source row information is available, it is returned.
- If it is not available:
- The function can still be used.
- The function returns null values in all cases.
For more information, see SOURCEROWNUMBER Function.
New Functions
| Function Name | Description |
|---|---|
| UNIQUE Function | Generates a new column containing an array of the unique values from a source column. |
Key Bug Fixes
None.
