This fix modified the following tests launched from test_queries.py by removing references to database 'functional' whenever possible. The objective of the change is to allow more testing coverage with different databases than the single 'functional' database. In the fix, neither new tables were added nor expected results were altered. empty.test inline-view-limit.test inline-view.test limit.test misc.test sort.test subquery-single-node.test subquery.test top-n.test union.test with-clause.test It was determined that other tests in testdata/workloads/functional-query/queries/QueryTest do not refer to 'functional' or the references are a must for some reason. Testing Ran query_tests on these changed tests with exhaustive exploration strategy.
