Using UTL_XML.PARSEQUERY for SQL Dependency Analysis

Last week I had a talk at Oracle’s OpenWorld 2011 titled Modern PL/SQL Code Checking and Dependency Analysis. The problem I described in chapter 4 was to find all view columns using the column UNIT_COST of the table COSTS in the SH schema. Other usages of this column (e.g. in where or […]
