I've a non id (key) column, a regular column that I want to defined with identity.

1. For HSQL
@Column(name = "NUMBER", columnDefinition="INTEGER GENERATED BY DEFAULT AS IDENTITY (start with 1)")
is OK

2. When I switch to Microsoft SQL server


When JPA persist, I got below exception.

Caused by: com.microsoft.sqlserver.jdbc.SQLServerException: Cannot insert explicit value for identity column in table 'CUSTOMER' when IDENTITY_INSERT is set to OFF.

So at database level, I set

SET IDENTITY_INSERT CUSTOMER ON

When JPA persist again, I still got the same exception. What do I miss?
