问题


I have a SQLite Datatable with string value as id and a BLOB value for a picture.

I want to know if some entry with a specific id exists in the table.

Query query = entityManager
            .createNativeQuery("SELECT logo_id FROM logo WHERE logo_id = ?");
    query.setParameter(1, id);
    int count = query.getResultList().size();

But if I execute the query I get this error.

... 71 more

And if I use this code , there are no probs.

Query query = entityManager
            .createNativeQuery("SELECT COUNT(*) FROM logo WHERE logo_id = ?");
    query.setParameter(1, id);
    Object o = query.getResultList().get(0);
    int count = Integer.valueOf(o.toString());

Why I'am getting an error in the other code version, because the select statement must be valid!?

Thanks.

回答1:


JDBC type: 0 means Null in java.sql.Types. The resultSet must contains null value, but hibernate could not support this datatype for SQLite. So you should set this mapping in your customize at.beko.rainstar2.dialect.SQLiteDialect. 

public class SQLiteDialect extends Dialect {
    public SQLiteDialect() {
        super();
        ...
        ...
        ...
        registerColumnType(Types.NULL, "null");
        registerHibernateType(Types.NULL, "null");
    }
    ...
    ...
}

I had a similar issue, in where my SQL query was normalising multiple rows into one column, giving;

org.hibernate.MappingException: No Dialect mapping for JDBC type: -9

So I had to wrap the XML result in a converter to convert it to varchar.

e.g. changed from

STUFF((select '   ' + RFID as [text()] from InnerTable inner 
       where inner.id = outer.id for XML PATH ('')), 1, 1, '') 
as RFIDs

to

CONVERT(varchar(100), 
STUFF((select '   ' + RFID as [text()] from InnerTable inner 
       where inner.id = outer.id for XML PATH ('')), 1, 1, '')
) as RFIDs
