Union In-DB Tool
The Union In-DB tool combines two or more In-DB data streams with similar data structures based on field names or field positions. In the output, each column will contain the data from each input.
This is an In-Database Tool.
In-Database enables blending and
analysis against large sets of data without moving the data out of a database
and can provide significant performance improvements over traditional
analysis methods. For more about the In-Database tool category, see In-Database Overview.
