Hi All,

I'm facing a NullPointerException in Hibernate 5.0.7 since I added the following line in a custom Dialect class overriding from SQLServerDialect.

Code:
registerHibernateType(Types.NCHAR, "char(1)");


Is there any alternative way to do this?

used query is

Code:
SELECT MULTI_GAME FROM ASSET.ASSET_CONFIGURATION_OPTION


Code:
null: java.lang.NullPointerException at org.hibernate.loader.custom.ScalarResultColumnProcessor.extract(ScalarResultColumnProcessor.java:54) at org.hibernate.loader.custom.ResultRowProcessor.buildResultRow(ResultRowProcessor.java:83) at org.hibernate.loader.custom.ResultRowProcessor.buildResultRow(ResultRowProcessor.java:60) at org.hibernate.loader.custom.CustomLoader.getResultColumnOrRow(CustomLoader.java:414) at org.hibernate.loader.Loader.getRowFromResultSet(Loader.java:756) at org.hibernate.loader.Loader.processResultSet(Loader.java:972) at org.hibernate.loader.Loader.doQuery(Loader.java:930) at org.hibernate.loader.Loader.doQueryAndInitializeNonLazyCollections(Loader.java:336) at org.hibernate.loader.Loader.doList(Loader.java:2611) at org.hibernate.loader.Loader.doList(Loader.java:2594) at org.hibernate.loader.Loader.listIgnoreQueryCache(Loader.java:2423) at org.hibernate.loader.Loader.list(Loader.java:2418) at org.hibernate.loader.custom.CustomLoader.list(CustomLoader.java:336) at org.hibernate.internal.SessionImpl.listCustomQuery(SessionImpl.java:1967) at org.hibernate.internal.AbstractSessionImpl.list(AbstractSessionImpl.java:322) at org.hibernate.internal.SQLQueryImpl.list(SQLQueryImpl.java:125)


Kindly help on the above issue and let us know in case of any alternative way is there. Thanks in advance.

If you debug it, it's the type variable that's null? Or is it something else?

Thanks for your earliest reply see below my comments.

Yes, when i debug type variable that's null and also observed basic(typeName) method had been searched for NCHAR class not available at run time hibernate framework it self doesn't have that StanderdBasicType constants.

let me know in case more details needed.

SqlServerDialect is a base class. What if you extend from SQLServer2012Dialect instead?

If you can provide a replicating test case, then you should open a Jira issue.
