Returns the union of two input sets, optionally retaining duplicates.
Union ( set1, set2 [,ALL] )
set1 | A set to join with set2. |
set2 | A set to join with set1. |
ALL | If the optional ALL keyword is used, duplicates are retained. |
Duplicates are eliminated by default from the tail of the set. The optional ALL keyword retains duplicates. The two input sets must have identical dimension signatures. For example, if set1 consists of dimensions Product and Market, in that order, then set2 should also consist of Product followed by Market.
