摘要：
A query generation using cardinality constraints process including choosing a first set of parameters for a query, calculating an additional set of parameters based on the first set of parameters, executing the query using additional set of parameters, evaluating the cardinality error the additional set of parameters, and refining the additional set of parameters to meet the desired cardinality constraint. Creating a query and selecting parameters for the query to meet a desired cardinality constraint or set of cardinality constraints when the query is executed against a database may be difficult. A query generation using cardinality constraints process may create a set of parameters for a query which satisfies a desired cardinality constraint or set of cardinality constraints. An application of such a query generation using cardinality constraints process may be database component and code testing.
