sql-server - Spring Data 和 SQL Server 在关键字“as”错误附近出现语法错误
问题描述
我正在尝试使用 Spring Data 从 SQL Server 表中读取数据。我有可以正常工作的本机查询，但我想改用 Spring Repository 和 find() 方法。
我定义了一个实体：
@Entity
@Table(name = "my table")
// This native query works when I try and use it.
@NamedNativeQuery(name = "Associate.getDistinctBusinessUnits",
query = "SELECT DISTINCT bus_unit_name FROM \"my table\" ORDER BY bus_unit_name"
)
public class Associate {
@Id
@Column(name = "assoc_oper_id", columnDefinition = "VARCHAR(50)")
public String assocOperId;
...
}
和一个存储库
@Repository
public interface AssociateRepository extends PagingAndSortingRepository<Associate, String> {
List<String> getDistinctBusinessUnits();
}
我的控制器正在调用存储库
// This query fails.
final Optional<Associate> result = associateRepository.findById(associateId);
但是当我得到
12147 [http-nio-8080-exec-1] ERROR o.h.e.jdbc.spi.SqlExceptionHelper - Incorrect syntax near the keyword 'as'.
12181 [http-nio-8080-exec-1] ERROR o.a.c.c.C.[.[.[.[dispatcherServlet] - Servlet.service() for servlet [dispatcherServlet] in context with path [/roster-service] threw exception [Request processing failed; nested exception is org.springframework.dao.InvalidDataAccessResourceUsageException: could not extract ResultSet; SQL [n/a]; nested exception is org.hibernate.exception.SQLGrammarException: could not extract ResultSet] with root cause

我知道我的数据库连接工作正常，因为我的本机查询存储库方法按预期工作。我已经尝试了几种不同风格的现有 Repository 方法以及我定义的方法来尝试得到相同的错误。
我的弹簧配置是
# ===============================
# DATABASE
# ===============================
spring.datasource.driver-class-name=com.microsoft.sqlserver.jdbc.SQLServerDriver
spring.datasource.url=jdbc:sqlserver://grddwmrtwhqipdw.northamerica.cerner.net:1433;databaseName=IPDW_PROD02
spring.datasource.username=ablab
spring.datasource.password=ablab
# ===============================
# JPA / HIBERNATE
# ===============================
spring.jpa.show-sql=true
spring.jpa.hibernate.ddl-auto=none
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.SQLServerDialect
我将 Spring Boot 2.1.3 与 Spring Data 2.1.5 一起使用（我确实尝试了 Spring Data 2.1.3，以防它们需要同步），我相信这是当前可用的最新版本。
我不拥有数据库服务器，也不知道如何从 SQL 明确检查版本，但我尝试了几种不同的方言。我也不知道哪里有一个司机所有可用方言的明确列表，所以我不知道我是否都试过了。
我对 Spring 和 Spring Data 的经验并不丰富。我已经以类似的方式针对 Oracle 使用了存储库，没有问题，所以我的猜测是 SqlServer 的一个特性。
任何人都有一些想法从这里去哪里？
谢谢！！
解决方案
@Table(name = "my table") 应该是 @Table(name = "`my table`")
