Named parameter not found in JPA/Hibernate native SQL queries

When using named parameters in native SQL queries with Hibernate implementation of the Java Persistence API (JPA), you may run into the following error

org.springframework.dao.InvalidDataAccessApiUsageException: Parameter with that name [orderId] did not exist; 
nested exception is java.lang.IllegalArgumentException: Parameter with that name [orderId] did not exist

This happens even if the named parameter was properly set, as in the following example :

For example :

void update(EntityManager em) {
    Query q = em.createNativeQuery("SELECT * FROM orders where id = :orderId;");
    q.setParameter("orderId", "1234");

The issue comes from Continue reading

Using Amazon Redshift with Hibernate

Amazon Redshift is not designed for ORMs like Hibernate. However, it sometimes may be useful to let Hibernate manage a couple of tables. For example, we were automatically generating some large tables for big-data analysis, and wanted to store metadata about the generated structures in the same database, to keep them in sync. Hibernate seemed convenient to manipulate these metadata.

First, that’s not a good idea. Hibernate tends to generate a lot of useless queries, unless you take the time to properly tweak it, you’ll feel the pain of letting Hibernate query a RedShift server on the other side of the planet (close to 0.5 second for a “SELECT 1” query sent to the database…).

Then, you’ll notice that Redshift SQL may be based on Postgres, still not everything is working as expected. Especially, postgres serial type (identity columns) are not supported.

Eventually, you’ll find out there’s no way to retrieve the value of the last identity generated for a inserted row. That’s a serious issue knowing that hibernate requires a primary key to identify inserted objects.

But if you still crave using Hibernate with RedShift, once you’ll have downloaded the JDBC driver, you may want to use this (unperfect) Hibernate Redshift dialect to get you started :

import org.hibernate.dialect.PostgreSQL82Dialect;
import org.hibernate.id.IdentityGenerator;

public class RedshiftDialect extends PostgreSQL82Dialect {

    public String getIdentitySelectString(String table, String column, int type) {
        // There's not method in the JDBC driver to retrieve the latest generated id.
        // So try to retrieve the largest id, and pray for no concurrent access.
        return "SELECT MAX("+column+") from "+table;

    public String getIdentitySelectString() {
        // Should never be called
        return "SELECT 1 FROM PG_TEST";

    public Class getNativeIdentifierGeneratorClass() {
        return IdentityGenerator.class;
    public String getIdentityColumnString( int type )
        // replace the Postgres "serial" type with RedShift Vertica one
        return "IDENTITY";
    public boolean hasDataTypeInIdentityColumn()
        return true;
