SQL for flat file database
I have a B+ tree flat file database which is used by the application we use.
I would like to implement a SQL kind of access for that DB.
I have implemented my data structures to parse and store the user written query for execution.
But i would like to know, do we have any standard data structures to store that SQL value, for execution purpose.
Please let me know about interfaces available in C.
Thanks
