Cognos Report Studio 版本 10.2.1 中格式化日期提示的问题

Question

我遇到了以下错误： UDA-SQL-0144 检测到算术异常。[IBM][CLI 驱动程序][DB2/NT64] SQL20448N“1993”无法使用格式字符串“YYYY-MM-DD”进行解释" 用于 TIMESTAMP_FORMAT 函数。 SQLSTATE=22007
我不太确定出了什么问题……我尝试更改格式，但没有帮助。 我正在使用 to_date 表单，但我不确定它是否正确。 这是我正在使用的 SQL 选择：

select laborcode,
(select sum(workhours) from workperiod where calnum='KOPA'and workdate between to_date(#prompt('StartDate','date')#,'YYYY-MM-DD') and to_date(#prompt('EndDate','date')#,'YYYY-MM-DD')) -
(select count(calnum) from workperiod where calnum='KOPA'and workdate between to_date(#prompt('StartDate','date')#,'YYYY-MM-DD') and to_date(#prompt('EndDate','date')#,'YYYY-MM-DD') and shiftnum='HOLIDAY') * 8 as stevilo_praznikov_ure,
(select sum(lt.regularhrs) from labtrans lt where lt.laborcode = l.laborcode and lt.orgid = l.orgid and startdate between to_date(#prompt('StartDate','date')#,'YYYY-MM-DD') and to_date(#prompt('EndDate','date')#,'YYYY-MM-DD')) as delovne_ure,
(select sum(ass.laborhrs) from assignment ass where ass.laborcode = l.laborcode and ass.scheduledate between to_date(#prompt('StartDate','date')#,'YYYY-MM-DD') and to_date(#prompt('EndDate','date')#,'YYYY-MM-DD')) as assignment_ure 
from labor l

我已经根据提示解决了问题。 我需要做的就是删除我在提示中的数据类型“日期” ，并将格式模式设置为YYYY-MM-DD ，它就可以正常工作了。 感谢大家的帮助，非常感谢！ 现在选择：

select laborcode,
(select sum(workhours) from workperiod where calnum='KOPA'and workdate between to_date(#prompt('StartDate')#,'YYYY-MM-DD') and to_date(#prompt('EndDate')#,'YYYY-MM-DD')) -
(select count(calnum) from workperiod where calnum='KOPA'and workdate between to_date(#prompt('StartDate')#,'YYYY-MM-DD') and to_date(#prompt('EndDate')#,'YYYY-MM-DD') and shiftnum='HOLIDAY') * 8 as stevilo_praznikov_ure,
(select sum(lt.regularhrs) from labtrans lt where lt.laborcode = l.laborcode and lt.orgid = l.orgid and startdate between to_date(#prompt('StartDate')#,'YYYY-MM-DD') and to_date(#prompt('EndDate')#,'YYYY-MM-DD')) as delovne_ure,
(select sum(ass.laborhrs) from assignment ass where ass.laborcode = l.laborcode and ass.scheduledate between to_date(#prompt('StartDate')#,'YYYY-MM-DD') and to_date(#prompt('EndDate')#,'YYYY-MM-DD')) as assignment_ure 
from labor l
