Can we design our own JDBC driver?

Question

I am thinking of desigining a JDBC driver which will be working bit like a bridge between the original drivers and users programs. My driver will give user an independence from syntax binding with the Database SQL and PL/SQL language. That is it will support (and convert) any SQL/PLSQL syntax and convert it according to the database user is using. I don't know whether it is possible or not. Please help me to check the feasibility of this.

I don't know if there are drivers that do what you want to do. However, there are a lot of open source drivers out there. If they don't do exactly what you want, by looking at their code you may get a better understanding of what it takes to code a jdbc driver.
Here are some links of other jdbc drivers (googled: open source jdbc)
the db engines provide jdbc drivers, so most all in the first link should have implementations.

I have my own performance tuning/monitoring api called JAMon. Currently it has the ability to track SQL performance, Exceptions and more by adding the following simple line of code to your program. The code below is db independent.
My next release will provide a jdbc proxy driver, so even the following code won't be needed.
import com.jamonapi.proxy.*;
Connection conn=...
Connection monConn=MonProxyFactory.monitor(conn);
