I tried your solution but I got many errors.

First of all you must know that there's no direct way to execute an SQL script file directly through JDBC
You can't load a SQL file into one statement and excute it.

You will have to write your own (very little) parser to split the script in individual statements and execute them one by one.
Splitting in Statements is the biggest challenge here ; so here is my solution :


DatabaseReseter.java


That's my solution, so try and tell me about it !!



Thanks for the great solution first!
I tried using it, but the problem is that my .sql file has INSERT queries for multiple tables. And so I am setting the values for each table's primary keys
however it gives an error. Could you please suggest something here?

Please see the stack trace below:
"*** Driver loaded
*** Error : com.mysql.jdbc.exceptions.jdbc4.MySQLIntegrityConstraintViolationException: Duplicate entry '1' for key 'PRIMARY'
***
*** Error :
com.mysql.jdbc.exceptions.jdbc4.MySQLIntegrityConstraintViolationException: Duplicate entry '1' for key 'PRIMARY'################################################
