I have a select query which is below

private String buildQuery (){

String queryFileinfo = "select S.id , S.fileType" + " from FileInfoBean S where ";
queryFileinfo = queryFileinfo + " S.fileName = '" + fileName + "'";
eturn queryFileinfo;
}

when I try running this query as

String QueryfileInfo = buildQuery();
Query hql = session.createQuery(QueryfileInfo);
Iterator i = null;
try {
System.gc();
i = hql.iterate(); ----------->> The execution hangs at this point
} catch (JDBCConnectionException e) {
uUakjsdbkalk}

The code does not throw any exception, can this be a issue with Hibernate?

Please help , its urgent
