How Can I Escape Reserved Words When Mapping JPA Entities?

Reserved Word Escaping in JPA Entity Mapping

When mapping entities in JPA, it's essential to consider reserved words in the database. For example, in SQL Server, the keyword "open" cannot be directly used as a field name.

In earlier versions of Hibernate (as a JPA 1.0 provider), reserved keywords could be escaped using backticks:

@Column(name="`open`")

This syntax forced Hibernate to quote the field name in the generated SQL, using the appropriate style for the underlying database dialect (e.g., double quotes for SQL Server).

In JPA 2.0, the escape syntax was standardized:

@Column(name="\"open\"")

By enclosing the reserved word in double quotes, JPA ensures that it's correctly escaped in the database.
