默认参数无法按预期工作

Question

我有一个使用3个参数显示的报告。我希望在打开报告时自动填充值。

但它显示如下：

Dataset1:

SELECT DISTINCT 
LectCode, LectName, AgeBand, RegYear, PRPH_ML1, 
[Curriculum Area], PRPH_Title, Section, Section_Name, 
Class_Register COLLATE DATABASE_DEFAULT + ' - ' + Register_Title 
COLLATE DATABASE_DEFAULT + ' - ' + Register_Day 
COLLATE DATABASE_DEFAULT + '  ' + CONVERT(char(5),
StartTime, 108) + ' - ' + CONVERT(char(5), EndTime, 108) AS Register, 
CourseType, Mins_Poss, Mins_Att, Mins_Late, TermTimeWeekNo, 
WeekStart, Class_Register, 
Register_Title, Register_Day, StartTime, EndTime, 
PrimaryProgramme, LectSection, LectDepartment
FROM            CurrentAttendance_New
WHERE        (RegYear = @Year) AND (CourseType IN (@CourseType)) 
AND (LectName IN (@Lecturer))
GROUP BY LectCode, LectName, AgeBand, RegYear, PRPH_ML1, 
[Curriculum Area], PRPH_Title, Section, Section_Name, 
CourseType, Mins_Poss, Mins_Att, Mins_Late, 
TermTimeWeekNo, WeekStart, Class_Register, Register_Title,
 Register_Day, StartTime, EndTime, 
 PrimaryProgramme, LectSection, LectDepartment
ORDER BY LectName, CourseType

Dataset2:
SELECT DISTINCT CourseType
FROM CurrentAttendance_New


Dataset3:

SELECT DISTINCT LectName
FROM            CurrentAttendance_New
WHERE        (CourseType IN (@CourseType))

我确保使用上述数据集中的值并设置默认值。

让我知道我哪里出错了。

在WHERE子句中，您是否拥有所有参数集？

WHERE @PLUMBING_VACANCY_3= "YES"等

此外，如果应在加载时选择这些值，则应在参数属性下的默认值中更改它们，并将Parameters =设置为您的值。
