Union In-DB Tool
Use the Union In-DB tool to combine two or more In-DB data streams with similar data structures based on field names or field positions. In the output, each column contains the data from each input.
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.
