Remarks
There is no sort order guarantee for the results.
Columns being joined on must have the same data type in both tables.
Only columns from the same source table (have the same lineage) are joined on. For example, Products[ProductID], WebSales[ProductdID], StoreSales[ProductdID] with many-to-one relationships between WebSales and StoreSales and the Products table based on the ProductID column, WebSales and StoreSales tables are joined on [ProductID]
Strict comparison semantics are used during join. There is no type coercion; for example, 1 does not equal 1.0.
