java.sql.SQLException: ORA-00932: inconsistent datatypes: expected NUMBER got BINARY

问题

I have a method in Dao Class that returns List<Object[]> back and I am using named Query

public List<Object[]> getListByCustomer(Session session, int customerId, List<Integer> strIds) {
  Query namedQuery = session.createSQLQuery(QueryConstants.EXPORT);
  namedQuery.setParameter("customer", customerId);
  namedQuery.setParameter("stringId", strIds);
  List<Object[]> objects = namedQuery.list();
  return objects;
}

I want to pass List<Integer> strIds in stringId into the named query as follows :

public class QueryConstants {
  public static final String EXPORT = 
    "SELECT sv.NAME, sv.TYPE, sv.CLIENT_ADDRESS, sv.NAME_REDUNDANT, sv.DEPARTURE_DATE, s1.CODE,sv.STATE, sv.CODE "
    + "FROM VIEW sv, PROCESS p1, SET s1 " 
    + "WHERE sv.R_ID = p1.R_ID and p1.ISSUER_ID = s1.USER_ID and sv.CUSTOMER_ID = :customer and sv.R_ID IN (:stringId)";
}

But I get ORA-00932: inconsistent datatypes: expected NUMBER got BINARY.

Also when I remove sv.R_ID IN (:stringId) from the query it works fine and when I pass Integer (strIds) instead of List<Integer> strIds into the query it works fine.

I'm using Oracle 10g.

回答1:

I think you just need to use

 IN :stringId

instead of

 IN (:stringId)

For JPA

namedQuery.setParameter("stringId", strIds);

is correct, but for Hibernate you should use

namedQuery.setParameterList("stringId", strIds);

回答2:

This is a very misleading error, and may root from different causes, for me I was setting a parameter that it was supposedly a number but at runtime it was setting null, hence it was binary. On a separate occasion got this error due to bean creation error in spring and was not setting the parameter correctly as well.

回答3:

I encountered this same exception and found the below reason for that -

In my entity, a field was mapped to a custom object (Parent child relationship - @ManyToOne). Later, the relationship annotation was removed by developer but the datatype was not changed.

After removing the @ManyToOne annotation, the @Column annotation should have been used with appropriate data type (Integer).
