我正在显示学生记录的成绩。他们坐在低年级(AS ...),然后选择继续某些课程到高年级(A ...)。这意味着我对每个学生都有以下数据集:
+----------------------+-------+-----------+-----+
| Name | Grade | End | Code|
+----------------------+-------+-----------+-----+
| A Business | C | 06-Jul-12 | BUS |
| A English | B | 06-Jul-12 | ELL |
| A History | C | 06-Jul-12 | HIS |
| AS Business Studies | E | 08-Jul-11 | BUS |
| AS Critical Thinking | B | 08-Jul-11 | CRT | <-- lower year only
| AS English | D | 08-Jul-11 | ELL |
| AS History | F | 08-Jul-11 | HIS |
+----------------------+-------+-----------+-----+
对于每个学生记录,我只想显示 A 和 AS 级别的成绩。在上面的例子中,这将抑制 AS 批判性思维:
A Business | C
A English | B
A History | C
AS Business Studies | E
AS English | D
AS History | F
在不编辑基础数据集的情况下,Crystal Reports 是否可以抑制那些仅显示为 AS 成绩的记录?例如:
If Code not present in records AND Name starts with AS
Suppress
Else
