Abstract
Query content-based data generation includes obtaining a query having an outer query and one or more subqueries, performing subquery transformation on each subquery, which converts predicates of the subqueries to be predicates of the outer query, and thereby obtain a transformed query, generate from the transformed query block(s) each having a list of predicates selected from the transformed query, processing each query block for column information, including column range information and column relationship information, and generating data and populating a dataset having table(s) and respective column(s) for each of the table(s). Generating the data uses the column range information and the column relationship information to select data for the dataset such that data records from the dataset are produced as results to executing the obtained query against the dataset.
