问题描述

基于选择查询构建一个表单,其中包含一个组合框(3个选项)

表单标题,它将为查询提供一个值。在

查询的标准中,我添加了以下表达式 - [Forms]![Form_1]!

[Combo_1],这就像一个魅力。但是我的一个用户希望在选择三个

选项之一之前看到所有值。


我添加了选择全部到我的组合下拉列表,并尝试按照iif语句后的

作为标准:

iff([Forms]![Form_1]![Combo_1] =" All",喜欢*,[Forms]![Form_1]!

[Combo_1])


我原来的3个选择仍然有用,但不是我的所有的" ;.我曾尝试过Like

*",Is Not Null和*但似乎没什么用。


有什么建议吗?

Built a form based on a select query with a combo box (3 choices) in
the form header which will supply a value to the query. In the
query''s criteria I added the following expression - [Forms]![Form_1]!
[Combo_1] and this works like a charm. However one of my users wanted
to see all of the values before choosing one of the three
selections.

I added the choice "All" to my combo dropdown list and tried the
following iif statement as the criteria:
iff([Forms]![Form_1]![Combo_1]="All",Like "*",[Forms]![Form_1]!
[Combo_1])

My original 3 choices still work but not my "All". I have tried "Like
"*"", "Is Not Null" and "*" but nothing seems to work.

Any suggestions?

Rick,


我应该忘记IIF声明并使用

建议的下一个标准?

Rick,

Should I forget the IIF statement and use the next criteria as you
suggest?
