setting "Allowed Values" for parameters with an SQL query
Hi,
Is there a way to define the list of allowed values for a parameter using an sql statement, rather than manually curating a list?
Many thanks,
George
Hi Eric
Thanks for getting back to me on this, but I don't think I explained clearly what I was trying to do, so unfortunately it doesn't really help.
Having done some digging it looks like what I'm trying to do will be in a future release (taken from here):
Parameter Accepted Values: In addition to Data Type restrictions, users can apply further restrictions to the allowed values for a given parameter. For instance, users could specify that the Data Type for a parameter is Text and restrict the acceptable values to a static list of Text values. Users will then be able to pick one of these values when specifying the parameter value to use. Currently, only a static list of Accepted Values (or any value of the expected type) are accepted. In future updates, we will enable users to bind the list of Accepted Values for a parameter to the output of another query.

Not 100% sure what is your point. Please check if this trick helps.
And in the advanced editor.
let Source = Sql.Database("servername", "testdb", [Query="select * from t1"&" where id in (" &valuelist& " )"]) in SourceHi Eric
