Abstract: Embodiments of the present invention provide methods and systems for increasing the flexibility and reusability of parameterized queries. A user may be allowed to select and run a predefined query. If the query is a parameterized query, the user may be prompted to input one or more parameters. Embodiments of the invention allow the user to recommend a parameter that retrieves maximum or minimum results for the query instead of specifying a parameter. In response to such a user selection, a predefined parameter may be inserted as a parameter for the query. Alternatively, the query may be modified by changing or removing one or more query conditions to achieve the desired results.

Abstract: A method, system and article of manufacture for managing presentation of query results. One embodiment comprises receiving, from a requesting entity, a query having at least (i) one result field for which data from one or more databases is to be returned, (ii) one or more conditions for filtering which of the data contained in the one or more databases is returned for each result field, and (iii) a conditions object defining at least one expression for at least one of the conditions. The query is executed against the one or more databases to obtain a query result having one or more data records. The query result is returned in a format relating the data records to respective expressions on the basis of which conditions the data records satisfy. Thereby, it is exposed which of the data records satisfy respective conditions having defined expressions in the conditions object.

Abstract: A method, system and article of manufacture for protecting sensitive data in databases and, more particularly, for managing access to sensitive data in a database. One embodiment comprises receiving a query against the data in the database comprising at least (i) a result field specification, and (ii) a sorting instruction. The method further comprises retrieving a result set from the database, and filtering the retrieved result set on the basis of predefined filtering rules to remove selected data from a selected result field of at least one data record included with the retrieved result set. The filtered result set is sorted according to the sorting instruction to produce the sorted result set, whereby the sorting is done independently of the removed selected data so that the sorted result set places the at least one data record at a position which is non-indicative of a value of the removed selected data.

Abstract: A method, system and article of manufacture for managing execution of queries against databases and more particularly for restricting access to sensitive data in underlying databases. One embodiment provides a method for managing access to sensitive data in a database. The method comprises receiving, from a requesting entity, a query against the data in the database. The query is executed against the database to obtain a result set. The method further comprises determining whether the result set includes sensitive data based on predefined sensitivity attributes associated with data in the result set. If so, a sensitivity rating is determined for the result set, and a predefined security action is preformed with respect to the result set on the basis of the determined sensitivity rating.
