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.

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.
regards matthias

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");
}
...
...
}
