向 SQL select 添加参数并在 Cognos Report Studio 版本 10.2.1 中使用它们

Question

我正在尝试将选择的日期参数放入我的选择中。 我不确定如何真正做到这一点。 现在我有固定的日期值，现在我想要一个参数，如：StartDate 和 EndDate。 我会非常感激任何帮助。 我的选择：

select laborcode,
(select sum(workhours) from workperiod where calnum='KOPA'and workdate between to_date('01.02.2020','DD.MM.YYYY') and to_date('01.03.2020','DD.MM.YYYY')) -  
(select count(calnum) from workperiod where calnum='KOPA'and workdate between to_date('01.02.2020','DD.MM.YYYY') and to_date('01.03.2020','DD.MM.YYYY') 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('01.02.2020','DD.MM.YYYY') and to_date('01.03.2020','DD.MM.YYYY')) as delovne_ure,
(select sum(ass.laborhrs) from assignment ass where ass.laborcode = l.laborcode and ass.scheduledate between to_date('01.02.2020','DD.MM.YYYY') and to_date('01.03.2020','DD.MM.YYYY')) as assignment_ure
from labor l

宏提示语法是 #prompt('StartDate','date')# 这会将您的 SQL 更改为：

选择劳动代码，（选择 sum(workhours) from workperiod where calnum='KOPA'and workdate between to_date(#prompt('StartDate','date')#,'DD.MM.YYYY') 和 to_date(#prompt(' EndDate','date')#,'DD.MM.YYYY')) -
(select count(calnum) from workperiod where calnum='KOPA'and workdate between to_date(#prompt('StartDate','date')#,'DD.MM.YYYY') 和 to_date(#prompt('EndDate', 'date')#,'DD.MM.YYYY') 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 和开始日期介于 to_date(#prompt('StartDate','date')#,'DD.MM.YYYY') 和 to_date(#prompt('EndDate','date')#,'DD.MM 之间。 YYYY')) 作为 delovne_ure, (select sum(ass.laborhrs) from assignment ass where ass.laborcode = l.laborcode and ass.scheduledate between to_date(#prompt('StartDate','date')#,'DD.MM .YYYY') 和 to_date(#prompt('EndDate','date')#,'DD.MM.YYYY')) 作为 assignment_ure from labour l
