Getting "Ordinal binding and Named binding cannot be combined" error

Question

Hello,
I am getting following exception while calling stored produre:
*"Ordinal binding and Named binding cannot be combined"*
I am calling stored procedure with JDBC with 1 input parameter and 1 output parameters as mentioned below:
CallableStatement collableStat = connection.prepareCall("{ call sp_clnt_intermed_validation(?,?) };
// Registering In parameters          
collableStat.setString("p_user_name", "SampleUser");                              
// Registering Out parameters
for(String paramKey : paramKeysSet) {                                   
collableStat.registerOutParameter("p_success_flag", Types.VARCHAR);
// execute stored procedure
collableStat.execute();
Please guide.
Regards,
Akshay.

Answer 1

Why is the registerOutParameter in a loop?
You don't state your DB version but as of 10g there is no support for named parameters for a PL/SQL function because there is no 'name' of the returned parameter. So use ordinal indexes for both parameters.
Instead of
collableStat.setString("p_user_name", "SampleUser");
collableStat.registerOutParameter("p_success_flag", Types.VARCHAR);use
collableStat.setString(1, "SampleUser");
collableStat.registerOutParameter(2, Types.VARCHAR);Next time post this in the JDBC forum.
