如何修复SQL语句中的H2语法错误？

mis*_*o89 5 sql h2

今天早些时候我询问了有关替换窗口函数的问题，因为 H2 不支持它。

我重写了 SQL 查询，但每次在 SQL 查询中出现语法错误（下面发布）

预期为“UNION、MINUS、EXCEPT、INTERSECT、ORDER、OFFSET、FETCH、LIMIT、FOR、）。

您能告诉我这个查询的错误在哪里吗？

@Query(value = "

（已编辑）由于最新版本的 H2 (2.x) 即使在基本查询中也不理解 SQLLIMIT关键字，因此您需要使用以下mode.limit = true;指令显式启用它：

Mode这可以通过以编程方式定义数据源并添加 2 行来定义 H2Oracle并将其limit选项设置为来完成true：

@Configuration
@EnableJpaRepositories
@EnableTransactionManagement
public class ServiceConfiguration {

  @Bean
  @Profile("test")
  public DataSource dataSource() {
    DriverManagerDataSource dataSource = new DriverManagerDataSource();
    dataSource.setDriverClassName("org.h2.Driver");
    dataSource.setUrl("jdbc:h2:mem:mydb;DB_CLOSE_DELAY=-1");
    dataSource.setUsername("sa");
    dataSource.setPassword("sa");

    // Ref https://groups.google.com/g/h2-database/c/yxnv64Ak-u8/m/n-kqYV_yBQAJ
    org.h2.engine.Mode mode = org.h2.engine.Mode.getInstance("ORACLE");
    mode.limit = true;

    return dataSource;
  }

}

或者，如果您的数据源是通过测试属性文件定义的（即不是以编程方式），您也可以mode.limit在其他地方设置该属性。例如，在集成测试文件中的所有测试之前执行的设置方法中，例如：

@SpringBootTest
public class MyIntegrationTest {

...

  @BeforeAll
  public static void setUpH2() {
    // Hack to fix H2 version 2.x not understanding the LIMIT keyword
    org.h2.engine.Mode mode = org.h2.engine.Mode.getInstance("Oracle");
    mode.limit = true;
  }

...

有了对象的句柄，org.h2.engine.Mode您还可以通过查看GitHub 上的类中的 H2 枚举Mode来设置其其他属性。

这个解决方案是由H2 的 Google 小组的 Evgenij Ryazanov 向我提供的，正如他所说，它涉及使用可能会在没有警告的情况下更改的内部代码。

至于使用profile进行测试，请参考Baeldung。

H2 从 1.4.198 开始支持窗口函数。如果您可以将 H2 升级到最新版本 (1.4.199)，最好这样做，而不是使用过于复杂的查询的解决方法，它们会比使用窗口函数的简单查询慢。

请注意，该FROM table)部分在 H2 的最新版本中无效，因为TABLE是一个关键字，如果您有一个具有该名称的表，则需要引用它（"TABLE"或"table"取决于您的设置）。

如果您确实需要使用一些不受支持的旧版 H2（例如 1.4.197 或更早版本），则需要在此处发布完整的错误消息。它包括带有标记的 SQL 命令，[*]该标记指示存在语法问题的位置。
