A union of two 1-row tables (two multiset relations each with one tuple) would have two rows (tuples) in the resulting relation. In relational algebra (which SQL isn't) the union result might be one row, though only if the two input relations contained an identical tuple, eg. self-union of a one-tuple relation. – Robert Monfera.There is a major difference between JOIN and UNION in SQL. Using the JOIN clause, we combine the attributes of two given relations and, as a result, form tuples. Whereas we use the UNION clause when we want to combine the results obtained from two queries. They both combine data differently. The format of the result that they obtain also varies.
