Grammer for basic arithmetic with variables

[Ralph Jocham]

Hi,
I am looking for a basic grammar which supports +,-,/,* and variables.

Assuming a=5, b=10

a+(3*b)/2 results in 20

I checked out the grammar site but could not find anything useful.

Thanks,
Ralph

If I recall correctly, there's a basic arithmetic "calculator" grammar
that comes shipped with javacc in the examples section.

Hi all,

has anyone written a grammar file for SQL queries? Specifically, we want to port mysql queries to db2 queries. Has anyone done that before?

Appreciate any help.

Hi Harshad,

Ain't sure if such a public tool exists.

However, there are available grammars at the javacc site for PL/SQL:
https://javacc.dev.java.net/servlets/ProjectDocumentList?folderID=110&expandFolder=110&folderID=0

Also you may find useful the following links:

Hope that helps something.
