- v. Simple past tense and past participle of upsert.
Sorry, no etymologies found.
When both operands are keyed tables having the same key and value columns, the result is a keyed table in which the records of the left operand are upserted with those of the right operand.
For two tables with the same count of records, join-each results in a column join (Column Join), in which columns with non-common names are juxtaposed and overlapping columns are upserted.
