I marked Der Golem's answer as correct as it was the right answer for the specific problem I said I was having.

Setting a DataRelation would work if it was. I'm still new to VB.NET, so please bear with me. I have two data tables, each filled from different database servers. They both have three columns (for ease of testing, final program will have 50+). They both have a common data column that

A common (i assume?) type of query: I have two tables ('products', 'productsales'). Each record in 'productsales' represents a sale (so it has 'date', 'quantity', 'product_id').
