Abstract
Provided are a method, system, and article of manufacture for a query predicate generator to construct a database query predicate from received query conditions. A plurality of query conditions are received, wherein each query condition includes a comparison operator and a comparison value for a database attribute, and wherein the comparison operator is capable of comprising matching and non-matching operators. The query conditions are processed to determine at least one logical operator to include between the query conditions. A database query predicate is generated to use in a database query to apply against the database comprising the received query conditions chained using the determined logical operators.
