A method, system and article of manufacture for query building and, more particularly, for building query conditions for queries against data in a database. One embodiment comprises receiving user input for constructing a first query condition of a query. Then, user-selectable elements to display for constructing a second query condition of the query are identified. Which user-selectable elements are identified is dependent on the first query condition. The identified user-selectable elements for constructing the second query condition are displayed. Then, user selection of one or more of the displayed user-selectable elements for constructing the second query condition is received. The first and second query conditions define selection criteria for selection of a specific set of the data from the database. The selection criteria are programmatically modified in response to construction of the second query condition on the basis of one or more predefined modification rules, whereby the specific set of the data is altered.
