Question

以下查询存在一些问题。我在这里使用的子查询在单独运行时运行时没有任何错误。但是，如果我在下面运行整个查询，则会以错误结束。 “编译语句时出错：FAILED：ParseException行13:30无法识别'select''max''附近的输入（''在表达式规范中”

select acct_num from table1
where ind = 'Y'
      and b = (select max(yr_mth_num) from table2)
      and st_dt = (select cast(max(st_dt) as date) from table2)

Answer 1

试试这个：

SELECT T1.acct_num 
FROM table1 T1 
LEFT SEMI JOIN 
    (SELECT 
        max(yr_mth_num) as max_yr_mth_num,
        cast(max(st_dt) as date) as max_st_dt
     FROM table2) T2
ON T1.b = T2.max_yr_mth_num
AND T1.st_dt = T2.max_st_dt
AND T1.ind = 'Y'

在HQL中使用MAX函数
