Inner Connection-INNER join The INNER JOIN creates a new result table based on the join predicate combining the column values of the two tables (table1 and table2). The query compares each row in table1 with each row in table2 to find matching pairs for all rows that satisfy the join predicate. When the join predicate is satisfied, the column values for each matching pair of rows A and B are merged into one result row. INNER JOIN is the most common type of connection and is the default connectio
