Sep 10, 2023 at 18:38 | comment | added | philipxy | Inner join does not return an intersection. It returns some of the rows of a cross join. It is not clear what you mean by "intersection" or by putting quotes around "intersection" or by "multiple inner joins give the intersection of all tables", or by "hence" or by an "intersection" of tables by a condition. It is not clear how to read that pseudo-Venn diagram, especially since SQL tables are bags of rows not sets of rows & result rows from JOIN have different columns from input tables & input tables don't have to have the same columns. (What are the sets & what are the elements?) PS minimal reproducible example | |
