Hello,

I am using Hibernate 3.3.1 GA and Oracle 9. I have many functions written in Oracle.
now I want to use that function in HQL but hibernate give following error


SQL : select getClientRank(?,?,?) from client_m where clientid=?
if I execute above query in SQl it will work fine. but I want to execute
same query in HQL

HQL : select getClientRank(?,?,?) from clientMaster where clientid=?
clientMaster is class for client_m table
but when I try to execut above HQL Query.

Hibernate give me following error

Hello All,
To solve my above problem, I tried to Register Sql Function. but it's also not working

I extends Oracle9Dialect as following

public class MyOracle9Dialect
extends net.sf.hibernate.dialect.Oracle9Dialect {
public Oracle9Dialect() {
super();
registerFunction("getClientRank", new StandardSQLFunction(Hibernate.INTEGER));
}
}


As per discussion in below link, oracle function with one argument will work.
So, I modify my getClientRank function and pass only one argument.
but then also it not working, It give me same error
