Hibernate No Dialect mapping for JDBC type: -1

[Abiodun Adisa]

I keep getting this error whenever i run the code below

public List getAllEmployerUsername(String username){
try {
String queryString = "select * from employer  where username=?";
SQLQuery queryObject = getSession().createSQLQuery(queryString);
queryObject.setParameter(0, username);
return queryObject.list();
} catch (RuntimeException re) {
throw re;
}

Any suggestion would be appreciated

There is a three-argument setParameter where you can specify the Hibernate type.

solved it by changing

select * from employer where username=?

to

select username from employer where username=?";
