Expressions: Case When Substring CharIndex

[David__Garcia]

I am using the following sql query to remove some unwanted strings.

  select case when sSource like '%<%%' then SUBSTRING(sSource, 1,charindex('<' ,SSource)-1) else sSource end
  from [xx].[xx].NmsTrackingUrl

It will cleanse the record and remove the string (<%   }                                         %>)

Now I am trying to do the same on a worflow but I am having trouble converting the expression.

Case(When(@source LIKE '<%', Substring(@source,1 , Charindex('<', @source)-1), Else(@source)))

The error is the following.. anyone can give me a hand?

I can see that the case expression is being interpreted wrongly by Neolane and it should be 'Case When' not 'Case(When' so I used the following expression instead, it also performs a CASE but the error is different now.

Iif(@source LIKE '<%', Substring(@source,1,Charindex('<%', @source)-1), @source)

I am running on w3schools testing page and it works fine.

I am using the following resources (Adobe Campaign Help | List of functions and Adobe Campaign Help | Advanced expression editing )

Instead of

Case(When(@source LIKE '<%', Substring(@source,1 , Charindex('<', @source)-1), Else(@source))) 

Try

Case(When(@source LIKE '%<%%', Substring(@source,1 , Charindex('<', @source)-1), Else(@source)))

Hi David,

Did that help?

not at all, I resorted to fixing the record's data on a database label
