Can you show us the code you are using?

[vamshidhar nimbagiri]

public void insert(String filePath, String state) throws IOException
{
List stateInfo = parseFile(filePath);

deleteRecords(state);

insertRecords(stateInfo);
}

public void deleteRecords(String state)
{
Session hs = getCurrentSQLServer2000Session();
int noOfRowsDeleted = hs.createQuery(DELETE_RECORDS_BY_STATE_HQL).setString(0,state).executeUpdate();
}


public void insertRecords(List recordsToInsert)
{
Session hs = getCurrentSQLServer2000Session();

for(int i=0;i<recordsToInsert.size();i++)
{
hs.save(recordsToInsert.get(i));
}
}
