HQL：转换为 SIGNED 是未知符号

Question

我需要将此查询转换为 HQL 语法：

SELECT * FROM my_table 
GROUP BY `name`
HAVING MIN(ABS(CAST(202000 AS SIGNED) -  CAST(step_id AS SIGNED))) = ABS(CAST(202000 AS 
SIGNED) -  CAST(step_id AS SIGNED));

我写了这个：

"SELECT DISTINCT t FROM myTable t GROUP BY t.name 
  HAVING MIN(ABS(CAST(202000 as signed) - CAST(t.step.id as signed))) = ABS(CAST(202000 as signed)- CAST(t.step.id as signed))"

但是我收到编译错误 - 红线位于关键字“signed”下：“无法解析符号“Signed””

我找不到正确将此查询转换为 HQL 的方法。

Answer 1

你能试试这个吗？只是用 int 替换了signed..

选择不同的t 来自 myTable t 按名称分组 HAVING MIN(ABS(CAST(202000 AS 整数) - CAST(t.stepId AS 整数))) = ABS(CAST(202000 AS 整数) - CAST(t.stepId AS 整数))
