Adding Lookup Function within a collection record

Posted on by Swagato

I am trying to add a new column as a look up column and store it in a local collection. I plan to use the new column as a column for the data table control.

I have noticed that normally without lookup, i.e. just some formatting added like formatting new column to add date format or currency format works. But whenever I use the lookup formula within add columns, the collection does not show any columns within it.

I am using the below expression to create the collection:

ClearCollect(tempCollection,
AddColumns(
'[dbo].[Category]',
"Observers",LookUp('[dbo].[Observers]',LOGIN_ID = OBS_LOGIN_ID,Concatenate(LAST_NAME,", ",FIRST_NAME))))

Hi @Swagato,

Check if there is anything wrong with the Concatenate(LAST_NAME,", ",FIRST_NAME) part. Make sure that only [dbo].[Observers] contain the LAST_NAME and FIRST_NAME column.

Hello,

The Observer table is the master table and only has information on FIRST_NAME and LAST_NAME. Also, this issue is not just with the expression I have mentioned. It has occurred for me for any lookup function on any table I use within the add columns and then creating a local collection out of it.

P.S. I am using an on-premise SQL Server database. Not sure whether it has anything to do with it.

i think your going to need to collect the observers table first with an addcolumns to do your concatenate, then do the lookup.
If you use addcolumns though you don't need concatenate anyway, just do: FirstName & " " & SurName (you could try this directly in your lookup but I don't think it works this way from memory).
