Table.Join
Table.Join(table1 as table, key1 as any, table2 as table, key2 as any, optional joinKind as nullable number, optional joinAlgorithm as nullable number, optional keyEqualityComparers as nullable list) as table
Joins the rows of table1 with the rows of table2 based on the equality of the values of the key columns selected by key1 (for table1) and key2 (for table2).
By default, an inner join is performed, however an optional joinKind may be included to specify the type of join. Options include:
JoinKind.InnerJoinKind.LeftOuterJoinKind.RightOuterJoinKind.FullOuterJoinKind.LeftAntiJoinKind.RightAnti
An optional set of keyEqualityComparers may be included to specify how to compare the key columns.
Inner join the two tables on [CustomerID]
Table.Join(Table.FromRecords({[CustomerID = 1, Name = "Bob", Phone = "123-4567"], [CustomerID = 2, Name = "Jim", Phone = "987-6543"], [CustomerID = 3, Name = "Paul", Phone = "543-7890"], [CustomerID = 4, Name = "Ringo", Phone = "232-1550"]}), "CustomerID", Table.FromRecords({ [OrderID = 1, CustomerID = 1, Item = "Fishing rod", Price = 100.0], [OrderID = 2, CustomerID = 1, Item = "1 lb. worms", Price = 5.0], [OrderID = 3, CustomerID = 2, Item = "Fishing net", Price = 25.0], [OrderID = 4, CustomerID = 3, Item = "Fish tazer", Price = 200.0], [OrderID = 5, CustomerID = 3, Item = "Bandaids", Price = 2.0], [OrderID = 6, CustomerID = 1, Item = "Tackle box", Price = 20.0], [OrderID = 7, CustomerID = 5, Item = "Bait", Price = 3.25], [OrderID = 8, CustomerID = 5, Item = "Fishing Rod", Price = 100.0], [OrderID = 9, CustomerID = 6, Item = "Bait", Price = 3.25]}), "CustomerID")
