Get one string from multiple options

bhaskarsharma03 — Mon, 19 May 2014 06:28:11 GMT

Hi,

I have a scenario where one ID may have multiple descriptions. I need to create a straight table to aggregate the Amount based on the ID's; however, only one description should appear in the straight table. I am OK to have any of the multiple descriptions, with no preference as such.

Please look at the attached image for more details.

Thanks in advance for your help.

Regards,

Bhaskar

If you dont care which description, then I would use an ApplyMap() to get the description. This functions much like a vlookup in Excel, so it will return the first match.

Create a mapping table:

Map_Names: Mapping Load Distinct

ID,

Description

Resident Data;

Now do an apply map:

Join(Data)

LOAD <some key field>,

ApplyMap('Map_Names', ID) As Description,

...

Use MaxString()/MinString() like in attached qvw.

=MaxString(Description)

Hi,

Thanks Tresesco and Ashfaq; this is exactly what I was looking for. Wonder why it didn't appear to me at the first place .

Thanks Jonathan for your response. I didn't want to use it at the script level, as in the actual implementation, I have around 15 fields where I need this solution; and all of them come from different tables . Since I will be using it in just couple of tables, I would rather do it at design level
