How to concatenate values from multiple rows

(0) ShareShare
ReportReport
Posted on by Carlik 55

Hello Experts

I'm working with report. I have a situation similar to classic

ID - EXTID - VALUE

1 - 1 - Val1

2 - 1 - Val2

I need to concatenate values

( Final result : 1 - Val1, Val2 )

using SQL 2 CDS tool (then I will traslate it in FetchXML);

I tried WITH CTE, FOR XML PATH, with no luck

How can I complete this task?

Thanks

    Hi,

    Thank you for your query.

    In SQL Server you can use STRING_AGG() for this purpose.

    For example:

    SELECT [IDColumn], STRING_AGG([ValueColumn], ',') [ContactVal]

FROM Table1

GROUP BY [IDColumn]

    However, as far as I know, this will not work in SQL 4 CDS (it does not support STRING_AGG).

    Also, the fetch xml has limited aggregation options (Sum, Count, Avg etc.):

    Use FetchXML aggregation (Microsoft Dataverse) - Power Apps | Microsoft Docs

    I guess, your only option is to user grouping in SSRS report (not in the query) or use Join operation in SSRS expressions to concatenate values form rows:

    reporting services - How to convert multiple rows into one row in SSRS? - Stack Overflow

    SSRS concatenate field in one string delimited by comma - without SQL (microsoft.com)
