Caused exception message is: Sql1 execute exception : UPDATE t_gl_acctcussent act SET fvchassistrecordid = (SELECT tem.FnewID from VTSDGOTT1O3BI7H8VVHAC2P18QAWI04SE9 tem where tem.FoldId = act.fvchassistrecordid and tem.FnewId is not null )  where fsourcebillid='11111111' and fcompanyid='D9gAAAAAJNDM567U' and fperiodid='D9gAAADpDRWCOIxM'Caused exception message is: 子查询返回的值不止一个。当子查询跟随在 =、!=、<、<=、>、>= 之后，或子查询用作表达式时，这种情况是不允许的。

select FOldAcctID from T_BD_AcctRefContrastentry where FACCTREFCONTRASTID  ='替换科目对照表ID' group by FOldAcctID having count(*)>1

处理方案：修改对照表，把查询出来的旧科目对
