[Ge Song, Kewei Wei, Xin Ying Yang] US NY Armonk In an approach for query processing, a computer receives a query. The computer determines the received query does not correspond to a previously executed query. The computer parses the received query to identify input literals that include one or more of: data values, tables, fields, records, and a parameter included in the received query. The computer determines whether a pattern is associated with the input literals included in the received query. Responsive to determining a pattern is associated with the input literals, the computer determines a future parameter based on the pattern associated with the input literals, wherein the future parameter is a subsequent instance of a parameter of the received query that corresponds to the pattern. The computer creates a future query by incorporating the determined future parameter into the received query.
