SSRS 2008 R2 如果为空则删除空格
我有一个简单的 SQL Server 2008 R2 报告，其中包含一个包含几个字段的文本框。如果字段的值为空，我想抑制该行。该表达式的语法是什么？
所以我的字段是...
Name
AddressLine1
AddressLine2
AddressLine3
CityStateZip
并且我有这样的表达式...
=First(Fields!AddressLine2.Value, "dsPersonData")
我正在尝试下面的表达式但出现错误
=IIF(Fields!AddressLine2.Value, "",True,False)
换句话说，如果该值是空字符串，我试图将可见性设置为 false 但我不确定语法是什么。
I have a simple SQL Server 2008 R2 report with a textbox containing a few fields. I want to suppress the line if the value of a field is null. What would be the syntax for the expression?
So my fields are...
Name
AddressLine1
AddressLine2
AddressLine3
CityStateZip
and I have expressions like this...
=First(Fields!AddressLine2.Value, "dsPersonData")
I was trying the expression below but getting errors
=IIF(Fields!AddressLine2.Value, "",True,False)
In other words I was trying to set the visibility to false if the value was an empty string but I'm not sure what the syntax would be.

你可以尝试
you can try
在 sql 查询中很容易做到这一点，例如：
在 SQL Server 中：
ISNULL(Name, '') as Name
ISNULL(AdressLine1, '') 作为 AdressLine1
ISNULL(AdressLine2, '') 作为 AdressLine2
ISNULL(AdressLine3, '') 作为 AdressLine3
ISNULL(CityStateZip, '') as CityStateZip
如果要将可见性设置为 false：
=IIF(First(Fields!AddressLine2.Value, "dsPersonData") = "",False,True)
Is easy to do this in the sql query, For example:
in SQL Server:
ISNULL(Name, '') as Name
ISNULL(AdressLine1, '') as AdressLine1
ISNULL(AdressLine2, '') as AdressLine2
ISNULL(AdressLine3, '') as AdressLine3
ISNULL(CityStateZip, '') as CityStateZip
and if you want to set the visibility to false:
=IIF(First(Fields!AddressLine2.Value, "dsPersonData") = "",False,True)
