From within [TRANSACTION], I need to, in the most efficient method possible, count the rows (there may be none) in [PERSON], via the field [PersonID]. I've searched, but, all the functions I've found seem to relate to the table I am working on, unless I'm completely misreading the articles.
TABLEs:
[TRANSACTION] > TransactionID, PersonID
[PERSON] > PersonID
You could use Table.Rowcount(Table.SelectRows(TRANSACTION, each List.Contains(PERSON[PersonID], [PersonID])))
Hello @BarrySmithCONSL
try some merging and transforming like this
let
Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMlTSAeJYnWglIzjLGMgyArNMgCxjMMsUyDIBs8yALFMwyxzOsgCyzJRiYwE=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type text) meta [Serialized.Text = true]) in type table [TransactionID = _t, PersonID = _t]),
PERSON =
let
Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMlSK1cFGGuEgjTFIE6XYWAA=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type text) meta [Serialized.Text = true]) in type table [PersonID = _t])
in
Source,
#"Merged Queries" = Table.NestedJoin
(
Source,
{"PersonID"},
PERSON,
{"PersonID"},
"PERSON",
JoinKind.LeftOuter
),
Transform = Table.TransformColumns
(
#"Merged Queries",
{{"PERSON", each if Table.IsEmpty(_) then 0 else Table.RowCount(_)}}
)
in
Transform
