Hibernate：获取错误“嵌套异常是org.Hibernate.MappingException：JDBC类型没有方言映射：-15”

Question

使用本机查询时出现异常嵌套异常为org . hibernate . mapping异常:没有JDBC类型的方言映射:-15

我的代码是

String sqlQuery = "select emp_id, name, address, dept from employee  where dept in ( Select dept  from department  where status=:status)";
Map<String, Object> queryParams = new HashMap<>();
queryParams.put("status", "Active");
Query sqlQuery = entityManager.createNativeQuery(query.toString());
queryParams.forEach(sqlQuery::setParameter);
List queryResults = (List) sqlQuery.getResultList(); // This line is throwing exception

我正在使用的数据库是 ： SQL服务器 2012.数据库配置是：

spring.datasource.username=testUser
spring.datasource.password=******
spring.datasource.url=jdbc:sqlserver://server:port;databaseName=testDB;
spring.datasource.driverClassName=com.microsoft.sqlserver.jdbc.SQLServerDriver
spring.datasource.hikari.maximum-pool-size=75
spring.datasource.hikari.idle-timeout=30000
spring.datasource.hikari.minimum-idle=10

spring.jpa.properties.hibernate.show_sql=true
spring.jpa.properties.hibernate.id.new_generator_mappings=false
spring.jpa.hibernate.ddl-auto=none
spring.jpa.properties.hibernate.generate_statistics=false

我真的不知道JPA对于员工和部门来说是什么样子，但是我看到你从两个不同的表中选择部门，你需要一些区分这些列的方法。

String sqlQuery = "select emp_id as emp_id  , name as name , address address, dept as dept  from employee  where dept in ( Select dept as dept_department  from department  where status=:status)";

参见下面的问题..Spring Data JPA将本地查询结果映射到非实体POJO
