Spring 数据 JPA/Flyway 转义双引号

Question

我有一个使用 Spring Data JPA、Flyway 和 H2 的 spring 引导项目，它正在尝试处理包含以下 SQL 语句的迁移脚本：

ALTER ROLE current_user SET search_path TO "$user", public, my_schema;

当 Flyway 尝试运行此迁移时，出现以下错误：

---------------------------------
SQL State  : 42001
Error Code : 42001
Message    : Syntax error in SQL statement "ALTER ROLE[*] CURRENT_USER SET SEARCH_PATH TO ""$user"", PUBLIC, MY_SCHEMA"; expected "TABLE, USER, INDEX, SCHEMA, SEQUENCE, VIEW"; SQL statement:
ALTER ROLE current_user SET search_path TO "$user", public, my_schema [42001-200]

看起来好像在这个过程的某个地方，"$user" 周围的双引号被另外一组引号转义了。

我该如何解决这个问题？

Answer 1

ALTER ROLE 无效 h2 Command. (and that is also, how the error message sounds like.) I think you mean rather GRANT ROLE!(?)
如果需要转义"，参考quoted names:

"anything"
| U&"anything" [ UESCAPE 'anything' ]
Case of characters in quoted names is preserved as is. Such names can contain spaces. The maximum name length is 256 characters. Two double quotes can be used to create a single double quote inside an identifier. With default settings identifiers in H2 are case sensitive.

所以"$user"应该没问题.
