Introduction :

- The Grammar Test Framework is the solution to assure Quality for the database vendors.

- You can test your DBMS with various other DBMS(s) for consistency in results.

- To test DBMS for their ANSI SQL 2003 compliance.


SQL Grammar (BNF)

BNF Grammar for ISO/IEC 9075-2:2003


Project Scope

Select Query

No Clause Description

1 Simple query SELECT columns FROM tables

2 WHERE WHERE columns op condition

3 GROUP BY GROUP BY columns

4 HAVING HAVING columns

5 Aggregate Function function (columns)

6 ORDER BY ORDER BY columns sort type

7 JOIN expression table join type table ON condition

8 Sub-Query

(1 level)

FROM (sub-query) alias

WHERE column op (sub-query)

Having column op (sub-query)

- Generating Select Query


Demo Step – 1.Select SQL BNF file


Demo Step – 2.Add DBMS to test

Model-view-control (MVC) is an architectural pattern used in software engineering. The pattern isolates business logic from input and presentation. Permitting independent development, testing and maintenance of each.

Limitation and Future work

1 Limitation

Presently only 77 production rules in the SQL BNF grammar file

Uses predefined Logical Data Model information

Difficulty in implementing classes for extendibility of SQL BNF grammar

2 Future work

Support for various SQL Query. (DML, DDL and DCL)

Generate query of all possible combination.

Extendibility to apply SQL Grammar file from DBMS vendors.

Use dynamic logical data model information define by user
