Abstract
A database system includes a parser that is capable of parsing database queries containing user-defined data type (UDT) methods. The database query is transformed by the parser into a statement according to a specified format. In performing the transformation, redundant instantiations of UDTs and invocations of methods are removed. In one implementation, the redundant instantiations and invocations are removed by grouping and combining clauses containing UDT methods.
