Most modern computer applications include an “advanced search” screen that allows users to enter multiple criteria and parameters. Unfortunately, behind the scenes, this functionality can cause major implementation headaches on the back end because the resulting queries may reference an unknown number of tables and/or columns and may return unknown numbers of rows. In addition, the results may mutate depending upon the parameters. There are multiple ways of solving this problem with various levels of efficiency. This presentation will demonstrate how to handle generic search functionality within an Oracle database by utilizing Dynamic SQL, object collections, and a bit of creativity.
