I am upgrading from 3.5.2 to 4.1.9
I am using SQL Server 2000
The error i see is
[SQLServer JDBC Driver][SQLServer]Column or parameter #9: Cannot find data type boolean.

Upon some investigation, i found that SQL Server does not have a boolean type.
Hibernate 3.5.2 used to hardcode the type of boolean to Types.bit in org.hibernate.type.BooleanType.sqlType().
Hibernate 4.1.9 does not do that.

One related bug i found is
https://hibernate.onjira.com/browse/HHH-6420

The commit for this bug is
https://github.com/hibernate/hibernate-orm/commit/d9680adcba4625f6330be7adfebb6fbcd2fb422d

Now in that commit, i don't understand why the following line
registerColumnType( Types.BOOLEAN, "bit" );
was added in SQLServer2005Dialect.java
instead of SQLServerDialect.java

I am positive that this is a bug.
Can someone help confirm this ?

As I can remember the type bit was introduced with SQLServer2005, therefore it is declared in SQLServer2005Dialect.java.


If you are using SQL Server 2000 you must refer SQLServerDialect (and not SQLServer2005Dialect),
so you should not get affected by HHH-6420 at all.

Check this.

Bit type was there in SQL Server 2000 as well.
I have checked hibernat 3.5.2's code and they do use Types.Bit


Yes i am using SQL Server 2000 but i didn't set any dialect.
I am letting Hibernate determine the dialect using StandardDialectResolver.
It figures out that i am using SQL Server 2000, sets the dialect to SQLServerDialect and fails.

If i explicitly set the dialect to SQLServer2005Dialect then it works but that's just a work around.

Sorry, your are right!
