I’m using JPA 2.2 and Hibernate 5.

Now I have an entity with a column like follows:

@Column(name = "a_name", columnDefinition = "TEXT")
private String text;

In my SqlServer DB I added the column this way:

ALTER TABLE [dbo].[mydb] ADD a_name text;

Now I retrieve a String, in JSON format, with Jackson ObjectMapper from a DTO.

When I try to persist the db I always obtain:

com.microsoft.sqlserver.jdbc.SQLServerException: Invalid column name 'a_name'. 

and this happens with any name I call the column..

I’m going mad.. please help!
