Different representation of UUID in Java Hibernate and SQL Server

Question

I am trying to map a UUID column in POJO to SQL Server table column using Hibernate.

The annotations are applied as follows:

@Id
@Genera         


        

Answer 1

You need to specify the @Type(type = "uuid-char") in addition to @Column(name="...", columnDefinition = "uniqueidentifier"), see also Problems mapping UUID in JPA/hibernate .

Alternatively you can use a String field for the id in Java and still keep uniqueidentifier in SQL Server.
