ERROR SchemaUpdate: 237 - рядом с "from": ошибка синтаксиса

Я новичок в Spring, и мне просто интересно, что означают эти ошибки?ERROR SchemaUpdate: 237 - рядом с "from": ошибка синтаксиса

ERROR SchemaUpdate:236 - HHH000388: Unsuccessful: create table FacebookPosts (id integer, created_time timestamp not null, from varchar not null, message varchar not null, picture_url varchar not null, post_id varchar not null, to varchar not null, updated_time timestamp not null, primary key (id)) 
ERROR SchemaUpdate:237 - near "from": syntax error

Я использую библиотеку Facebook Spring Social для получения последних сообщений и хранения их в базе данных SQLite.

Мой код выглядит следующим образом:

from является reserved word in SQLite. Вы можете либо использовать другое имя (если возможно), либо указать его, как указано в связанном URL:

Если вы хотите использовать ключевое слово в качестве имени, вам нужно процитировать его. Там четыре способа процитировать ключевые слова в SQLite:

«ключевого слово» - Ключевое слово в одинарных кавычках строкового литерала.

«keyword» - ключевое слово в двойных кавычках является идентификатором.

[keyword] - Ключевое слово, заключенное в квадратные скобки, является идентификатором. Это не стандартный SQL. Этот механизм цитирования используется MS Access и SQL Server и включен в SQLite для обеспечения совместимости.

`keyword` - ключевое слово, заключенное в глубокие акценты (код ASCII 96), является идентификатором. Это не стандартный SQL. Этот механизм цитирования - , используемый MySQL и включен в SQLite для обеспечения совместимости.

Согласно JPA spec (вы должны принять их лицензионное соглашение), кажется, предпочтительнее использовать двойные кавычки:

@Column(name = "\"from\"", nullable = false) 
private String from;

Cf. my related answer для более подробной информации (Hibernate и HSQL).
