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
Kumaran

I have never come across any published standard data structures to store SQL queries for execution purposes. Generally such structures are specific to a particular database and are not standardized as there simply is no reason to.

One more question.

I have the database server running in node 1 and processing requests from node2.

Suppose if node2 sends a select query for a big table, how do i transmit data from node1 to node2. Please suggest me.

Should i do in the generator form that is as and when the user navigates through the result set, i send more rows for further navigation. this would give me advantage that my response to node2 would be fast becuase i don't have to send all rows to node to complete the response.

But when i do so, i must keep the table in tact between the send() calls, otherwise i have to keep a copy of selected rows. Please advice me.

Any new ideas to do this.

Thanks
Kumaran
