boolean type is not identified while creating tables with hibernate using Microsoft Sql Server 2008. Its not identified and binded automatically with respctive data type of Sql server.
Sql server data type for boolean is "BIT" which I need to specifically need to mention in column definition described as follow:

@Column(name = "is_treat_expired", columnDefinition = "BIT")
private Boolean isTreatExpiry;

I believe this could be a problem of the sql server dialect.

I faced this problem while using envers. I want to use a property of "@Audited" annotation naming "withModifiedFlag" which is a boolean flag. This actually adds a boolean specific column in the respected audit table . But as boolean is not identified directly and we don't have access to entity generated for audit tables, hibernate fails to generate audit table for that entity.
