Correct JPA Annotation for PostgreSQL's text type without Hibernate Annotations

Question

I\'m developing an application using:

• Java 1.7
• JPA (included in javaee-api 7.0)
• Hibernate 4.3.8.Final
• PostgreSQL-JDBC 9.4-1200-jdbc4

Answer 1

Since the text type is not a part of the SQL standard there is no official JPA way I guess.

However, the text type is quite similar to varchar, but without the length limit. You can hint the JPA implementation with the length property of @Column:

@Column(length=10485760)
private String description;

Update: 10 MiB seems to be the maximum length for varchar in postgresql. The text is almost unlimited, according the documentation:

In any case, the longest possible character string that can be stored is about 1 GB.
