Excel OData: Multiple Queries from Multiple Sources

Anonymous — Tue, 10 Jan 2023 02:11:52 GMT

Hello,

I was hoping someone might be able to tell me if it is possible to build a set of queries, loaded to tables in Excel, from a list of sources. I;'ve worked with single parameters before (like pasing a DATE into a query) but never iterating through a 'list' of parameters.

With my limited knowledge, I understand that a standard query has a source, formed somethign like this;

Source = OData.Feed("SOURCE_ENETERED_HERE", null, [Implementation="2.0"]), THIS_IS_MY_DATA_table = Source{[Name="THIS_IS_MY_DATA",Signature="table"]}[Data],

What I would like to do is load a 'list' of data source names into a table in Power Query and the generate the queries from these, I currently create these manually, somethign like;

Source = OData.Feed('SOURCE_ENETERED_HERE', null, [Implementation='2.0']), THIS_IS_MY_DATA_1_table = Source{[Name='THIS_IS_MY_DATA_1',Signature='table']}[Data], Source = OData.Feed('SOURCE_ENETERED_HERE', null, [Implementation='2.0']), THIS_IS_MY_DATA_2_table = Source{[Name='THIS_IS_MY_DATA_2',Signature='table']}[Data], Source = OData.Feed('SOURCE_ENETERED_HERE', null, [Implementation='2.0']), THIS_IS_MY_DATA_3_table = Source{[Name='THIS_IS_MY_DATA_3',Signature='table']}[Data], Source = OData.Feed('SOURCE_ENETERED_HERE', null, [Implementation='2.0']), THIS_IS_MY_DATA_4_table = Source{[Name='THIS_IS_MY_DATA_4',Signature='table']}[Data], Source = OData.Feed('SOURCE_ENETERED_HERE', null, [Implementation='2.0']), THIS_IS_MY_DATA_5_table = Source{[Name='THIS_IS_MY_DATA_5',Signature='table']}[Data], Source = OData.Feed('SOURCE_ENETERED_HERE', null, [Implementation='2.0']), THIS_IS_MY_DATA_6_table = Source{[Name='THIS_IS_MY_DATA_6',Signature='table']}[Data], Source = OData.Feed('SOURCE_ENETERED_HERE', null, [Implementation='2.0']), THIS_IS_MY_DATA_7_table = Source{[Name='THIS_IS_MY_DATA_7',Signature='table']}[Data], Source = OData.Feed('SOURCE_ENETERED_HERE', null, [Implementation='2.0']), THIS_IS_MY_DATA_8_table = Source{[Name='THIS_IS_MY_DATA_8',Signature='table']}[Data], Source = OData.Feed('SOURCE_ENETERED_HERE', null, [Implementation='2.0']), THIS_IS_MY_DATA_9_table = Source{[Name='THIS_IS_MY_DATA_9',Signature='table']}[Data], Source = OData.Feed('SOURCE_ENETERED_HERE', null, [Implementation='2.0']), THIS_IS_MY_DATA_10_table = Source{[Name='THIS_IS_MY_DATA_10',Signature='table']}[Data], Source = OData.Feed('SOURCE_ENETERED_HERE', null, [Implementation='2.0']), THIS_IS_MY_DATA_11_table = Source{[Name='THIS_IS_MY_DATA_11',Signature='table']}[Data], Source = OData.Feed('SOURCE_ENETERED_HERE', null, [Implementation='2.0']), THIS_IS_MY_DATA_12_table = Source{[Name='THIS_IS_MY_DATA_12',Signature='table']}[Data], Source = OData.Feed('SOURCE_ENETERED_HERE', null, [Implementation='2.0']), THIS_IS_MY_DATA_13_table = Source{[Name='THIS_IS_MY_DATA_13',Signature='table']}[Data], Source = OData.Feed('SOURCE_ENETERED_HERE', null, [Implementation='2.0']), THIS_IS_MY_DATA_14_table = Source{[Name='THIS_IS_MY_DATA_14',Signature='table']}[Data], Source = OData.Feed('SOURCE_ENETERED_HERE', null, [Implementation='2.0']), THIS_IS_MY_DATA_15_table = Source{[Name='THIS_IS_MY_DATA_15',Signature='table']}[Data], Source = OData.Feed('SOURCE_ENETERED_HERE', null, [Implementation='2.0']), THIS_IS_MY_DATA_16_table = Source{[Name='THIS_IS_MY_DATA_16',Signature='table']}[Data], Source = OData.Feed('SOURCE_ENETERED_HERE', null, [Implementation='2.0']), THIS_IS_MY_DATA_17_table = Source{[Name='THIS_IS_MY_DATA_17',Signature='table']}[Data], Source = OData.Feed('SOURCE_ENETERED_HERE', null, [Implementation='2.0']), THIS_IS_MY_DATA_18_table = Source{[Name='THIS_IS_MY_DATA_18',Signature='table']}[Data], Source = OData.Feed('SOURCE_ENETERED_HERE', null, [Implementation='2.0']), THIS_IS_MY_DATA_19_table = Source{[Name='THIS_IS_MY_DATA_19',Signature='table']}[Data], Source = OData.Feed('SOURCE_ENETERED_HERE', null, [Implementation='2.0']), THIS_IS_MY_DATA_20_table = Source{[Name='THIS_IS_MY_DATA_20',Signature='table']}[Data],

What would be great, would be to store the following in a table in power query and then have power query 'iterate' though the list and create the 20 queries (and tables) in excel for me, is this possible?

THIS_IS_MY_DATA_1

Hi Anonymous ,

Technically it's possible. You would essentially just replace the references in the Source/Navigation steps to a position in your list.

So, references to 'THIS_IS_MY_DATA_1' would become 'LIST OF DATA SOURCES'{0}.

There will be other intricacies to getting this to work exactly as required (for example, error handling queries that reference a list position beyond the length of your source list etc.), but this is the principle of the method.
