Question

我有以下sql查询： -

select b.LOGTIME, b.beam_current, b.beam_energy,
  case when a.st1_vs1_bag1_onoff=0 and a.logtime=c.logtime then c.st1_vs1_bag1_rb ELSE 0 END as st1_vs1_bag1_rb ,
  CASE when a.st1_vs1_bag2_onoff='0' and a.logtime=c.logtime then c.st1_vs1_bag2_rb else '0' END as st1_vs1_bag2_rb ,
  CASE when a.st1_vs1_bag3_onoff='0' and a.logtime=c.logtime then c.st1_vs1_bag3_rb else '0' END as st1_vs1_bag3_rb ,
  CASE when a.st1_vs1_bag4_onoff='0' and a.logtime=c.logtime then c.st1_vs1_bag4_rb else '0' END as st1_vs1_bag4_rb ,
  CASE when a.st1_vs1_bag5_onoff='0' and a.logtime=c.logtime then c.st1_vs1_bag5_rb else '0' END as st1_vs1_bag5_rb ,
  CASE when a.st1_vs1_bag6_onoff='0' and a.logtime=c.logtime then c.st1_vs1_bag6_rb else '0' END as st1_vs1_bag6_rb ,
  CASE when a.st1_vs1_bag7_onoff='0' and a.logtime=c.logtime then c.st1_vs1_bag7_rb else '0' END as st1_vs1_bag7_rb ,
  CASE when a.st1_vs1_bag8_onoff='0' and a.logtime=c.logtime then c.st1_vs1_bag8_rb else '0' END as st1_vs1_bag8_rb 

from INDUS2_BDS.dbo.DCCT b  INNER JOIN (main_vacuum_analog c inner join main_vacuum_status a on c.logtime=a.logtime) ON a.LOGTIME = b.LOGTIME 
and  b.beam_current LIKE '%0' 
and (cast(b.beam_current as int) % 10.0 <= 0.01 OR b.beam_current % 10.0 >= 9.99)
and (cast(b.beam_current as int) >= 9.99) -- to set the lower limit of 9.99
and (cast(b.beam_current as int) <= 220.01)
and b.logtime between '2014-10-10 07:17:00' and '2014-10-10 08:46:00'

但是当我执行此查询时，我收到以下错误消息

The data types real and numeric are incompatible in the modulo operator.

我该如何解决？我想只显示附近的beam_current值，从10,20,30到220。

Answer 1

我得到了答案： -

  (cast(cast(b.beam_current as decimal) % 10.0 as real) <= 0.01) 
and (cast(cast(b.beam_current as decimal)as real) >= 9.99) -- to set the lower limit of 9.99
and (cast(cast(b.beam_current as decimal)as real) <= 220.10)
 and b.logtime between '2014-10-10 07:17:00' and '2014-10-10 08:46:00'

实数和数字的数据类型在模运算符中是不兼容的
