Using XML as a common parser architecture to separate parser from compiler

摘要

A method and apparatus for compiling queries is provided. A first query in a first syntax of a query language is received. Based on the first query, a second query in a second syntax of the query language is generated. The first syntax and the second syntax are each among a plurality of syntaxes that are defined for the query language. The second query is parsed to generate parsed information. Based on the parsed information, the second query is compiled by a compiler that does not support compiling of queries in the first syntax.
