I have two tables, one of them has weeks of year, and the second table has categories. I need to create a table that contains each week and each category, but there's no fields/keys that intersect in two tables:
Table 1:
week1 week2 week3 week4 Table 2:
Cat1 Cat2 Resulting table:
week1 cat1 week1 cat2 week2 cat1 week2 cat2 ... week4 cat1 week4 cat2 I'd like to do this without using many cursors/looping.

A foreign key is not required either. You can construct a query joining two tables on any column you wish as long as the datatypes either match or are converted to match. No relationship needs to explicitly exist.
Yes, you can! The longer answer is yes, there are a few ways to combine two tables without a common column, including CROSS JOIN (Cartesian product) and UNION. The latter is technically not a join but can be handy for merging tables in SQL. In this article, I'll guide you through the different solutions with examples.
SELECT * FROM Table1 CROSS JOIN Table2 This will get you every combination of all columns from Table1 and Table2.
