Design and implementation for SQL parser based on ANTLR

To solve the close relationship between the data query and interface design of management information system, the paper implements a SQL parser based on ANTLR. The SQL parser is composed of lexical analysis, syntax analysis and semantic checking. The SQL parser is successfully integrated with management information system and the query is implemented by the SQL parser to search the data from database. It solves the problem that the relationship between the data query and interface design of management information system is very close, and improves the reliability and reusability of the software.
