Question

我正试图运行此更新语句（至少对我而言）。它应该非常简单，但我无法克服这个障碍。每次我尝试运行它时，都会抛出错误

第15行，第1行，第1行，第1行关键字＆＃39;其中＆＃39;。
附近的语法不正确

我已经检查了所有的字段名称并且它们是有效的，并且我已经尽我所能来克服这个障碍，但是我被击败了。

update #holdingdata
set 1e2a3m = (select count(*) 
                 from subtodom.blaize.dbo.sassafras 
                 where employeename in (select ename 
                                       from subtodom.hr.dbo.employees 
                                       where status in ('Active') 
                 and CAST(hiredate As Date) between 'Jan 13 2015 12:00AM' and 'Jan 115 2015 12:00AM') 
where manager = 'Jeff'

Answer 1

update #holdingdata
set 1e2a3m = (select count(*) 
                 from subtodom.blaize.dbo.sassafras 
                 where employeename in (select ename 
                                       from subtodom.hr.dbo.employees 
                                       where status in ('Active') )
                 and CAST(hiredate As Date) between 'Jan 13 2015 12:00AM' and 'Jan 115 2015 12:00AM') 
where manager = 'Jeff'

Answer 2

这会更容易被读作连接而不是两个子查询（希望仍能产生相同的结果吗？）

update #holdingdata
set 1e2a3m = (
  select count(*) 
  from subtodom.blaize.dbo.sassafras blaize 
  INNER JOIN subtodom.hr.dbo.employees hr 
    ON( blaize.employeename = hr.ename )
  WHERE hr.status = 'Active' AND
  CAST(blaize.hiredate As Date) between 'Jan 13 2015 12:00AM' 
    and 'Jan 115 2015 12:00AM'
)
WHERE manager = 'Jeff'

也许还将count（*）替换为count（distinct blaize.employeename）

每次更新语句错误
