DbUnit HSQLDB-无效的架构名称：C

如何解决DbUnit HSQLDB-无效的架构名称：C

| 使用以下查询运行测试时，HsqlDB会将表别名误认为是架构。

SELECT c.country_ml2country as CTRY_PK,c.name as CTRY_NAME,l.name as LANGUAGE_NAME,l.code as LANGUAGE_CODE
FROM country_ml as c,language as l
WHERE c.language(+) = l.id and c.country_ml2country(+) = ?
ORDER BY l.name ASC;

有谁之前经历过这个吗？如果“是”，那么解决方法是什么？ 请注意，如果我将“ 1”更改为“ 2”，则错误消息将相应地更改为“ 3”。     

解决方法

问题是非标准的Oracle风格的OUTER JOIN语法，该语法特定于Oracle，其他SQL方言不支持。

WHERE c.language(+) = l.id and c.country_ml2country(+) = ?

您应该改用Oracle也支持的以下标准语法：

SELECT c.country_ml2country as CTRY_PK,c.name as CTRY_NAME,l.name as LANGUAGE_NAME,l.code as LANGUAGE_CODE
FROM country_ml as c RIGHT OUTER JOIN language as l
ON c.language = l.id and c.country_ml2country = ?
ORDER BY l.name ASC
