Internal ConnectionThe INNER JOIN query operation lists the data rows that match the join criteria, and it uses comparison operators to compare the column values of the concatenated columns. Direct examples to illustrate: vendors and products are two tables in the database, which are joined by the vend_id column,vend_id as the primary key in Vendors , and it is a foreign key in the products, and the results are two tables respectively.3.2.2 Outer couplingThe outer coupling is
