Question 8

When using a Union tool with the 'Auto Config by Position' setting, what happens if the incoming stream has an extra column that the other streams do not have?

Accepted Answer

The column is created, and missing values are populated with nulls. In 'Auto Config by Position' mode, Alteryx aligns columns based on their index (1st column, 2nd column, etc.). If one input contains an extra column at the end, the tool will include that column in the final output and fill the rows from other input streams with null values. This ensures all data is preserved, which is critical when dealing with multiple sources that have slight variations in structure.

Answer

The extra column is automatically dropped

Answer

The tool throws an error and stops

Answer

It forces the extra column to merge with the first column

Question 9
