I'm getting this error:
java.lang.ClassCastException: java.math.BigInteger cannot be cast to java.lang.Integer
My idea is to check the count value of a select, but I'm having trouble to convert it.
attaching the code below.
Any ideas?
public List<Map<String, Object>> contaQuery(String sqlCount) throws MensagemException {
Session session = HibernateUtil.getSession();
try {
String sql = sqlCount;
int query = ((Integer) session.createSQLQuery("select count(*) from (" + sqlCount + ") as subquery")
.uniqueResult());
if (query <= 50000) {
return rodarQuery(sql);
} else {
throw new MensagemException("Too many Registers");
}
} finally {
session.close();
}
}
As stated in the Farlan comment, convert the BigInteger return value from the uniqueResult to an Integer by calling intValue()
final Query query;
final BigInteger bigResult;
final int result;
query = session.createSQLQuery("select count(*) from (" + sqlCount + ") as subquery");
bigResult = (BigInteger)query.uniqueResult();
if (bigResult != null)
{
result = bigResult.intValue();
}
else
{
result = ...some value of your choosing, perhaps 0.
)
if (result < 50000)
... stuff
