To mix results from many tables, use the FROM clause to call more than one table. You can reference columns from each of these tables in your result set by using the AS keyword followed by the column name. For example, suppose you wanted to retrieve the names and email addresses for everyone in your database who was at least 18 years old.
You could write this as a single query, or you could break it up into two separate queries by age group. Using two separate queries makes it easier to avoid duplicating information across tables and simplifies reporting later. One way would be to create a new table called "merged" and copy all the user data into that table. Then you could use the merged table in future reports or applications. However, this is not the most efficient approach since it requires another table scan.

Values returned A method may or may not return a value, whereas a function always does. Conclusion In conclusion, a function is a piece of code that performs a task and returns a result while a procedure is a subroutine that can perform tasks associated with roles.
