The illustration of MYSQLJOINON and SQLJOIN is detailed. SQL Join statements in databases may be messy during learning. We know that the Join syntax of SQL has many inner, outer, and left clauses. sometimes, it is not clear about the result set of Select statements. In an article on Coding Horror (it is not clear why Coding Horror is also walled), Venn diagrams explains SQL Join. I think it's easy to understand. Suppose we have two tables. TableIs
