20150220597 | DECORRELATION OF USER-DEFINED FUNCTION INVOCATIONS IN QUERIES - Systems, methods, and computer-readable medium, are disclosed for transforming user-defined-function invocations in a query-based environment. A user-defined-function (UDF) and a query invoking the UDF are received. The UDF is parsed into a plurality of statements. A first expression tree corresponding to the UDF and a second expression tree corresponding the query are constructed, and merged using an operator to generate a transformed expression. The transformed expression is simplified, using transformation rules, if it is determined that is can be simplified. | 08-06-2015 |
