Question

我正在使用具有多个＆＃34;代码的表中的列/字段＆＃34;或者＆＃34; ids＆＃34;与之相关。

表 afacctbal 有一个名为 afacbbalid 的列/字段，其中可能包括COST，PRN或COLL。

我遇到的问题是在账户上提取COST等于0的行。

我在where子句中尝试了一个子查询的SQL语句，但返回了一般错误。现在我正在尝试使用IN语句，但这似乎也不起作用。

以下是我所得到的：

select araccount.aracid as AccountID, arentity.arenst State, arentity.ARENNAME ClientName,
 afaccount.afaccurbal CurrentBal, afacctbal.afacbcurbal PrincipalBal,
  afacctbal.AFACBbalid
from araccount
 inner join arrelationship on araccount.aracid = arrelationship.arrelacid
 inner join arentity on arentity.arenid = arrelationship.ARRELENID
 inner join afaccount on afaccount.afacacctid = araccount.ARACID
 inner join afacctbal on afaccount.AFACKEY = afacctbal.AFACBACCTID
where afacctbal.afacbbalid in("COST",0)
    and afaccount.AFACRATEID = "MN100"
    and arentity.ARENST = "MN"
    and araccount.araclstdte > "2013-04-01"
order by afaccount.afaccurbal

麻烦在于我的where子句这里：

where afacctbal.afacbbalid in("COST",0)

我如何检查COST并检查它是否等于0？

AFACCTBAL TABLLE 使用价值： afacbbalid - balance id afacbcurbal - 每个余额的余额。 afaccount表使用价值： afaccurbal - 当前余额

Answer 1

您使用的是"COST"字符串，然后是0这是一个整数。因此，您需要在afacctbal.afacbbalid列中的数据类型中转换它们。

Answer 2

我认为以下查询将符合您的要求 -

select araccount.aracid as AccountID, arentity.arenst State, arentity.ARENNAME ClientName,
 afaccount.afaccurbal CurrentBal, afacctbal.afacbcurbal PrincipalBal,
  afacctbal.AFACBbalid
from araccount
 inner join arrelationship on araccount.aracid = arrelationship.arrelacid
 inner join arentity on arentity.arenid = arrelationship.ARRELENID
 inner join afaccount on afaccount.afacacctid = araccount.ARACID
 inner join afacctbal on afaccount.AFACKEY = afacctbal.AFACBACCTID
where ((afacctbal.afacbbalid ='COST'
    and afaccurbal.currentBal = 0) or 
     (afacctbal.afacbbalid ='PRN'
    and afaccurbal.currentBal > 0))
    and afaccount.AFACRATEID = "MN100"
    and arentity.ARENST = "MN"
    and araccount.araclstdte > "2013-04-01"
order by afaccount.afaccurbal

SQL IN语句没有正确检查？
