and falls within the cateogory of simple view. Any change /
modification on the records will be reflected in the base
table.

Hi
Not only on a single based table, changes made on a view
which created on multiple tables also will update on base
tables,if the relation ship between primary key and Foreign
key relationships are proper and if the Integrity
constraints are mentioned.
Cheers!

What is raw datatype in sql?
SELECT emp_num, years, SUM(salary) FROM sales UNION ALL SELECT emp_id, SUM(takehomepay) FROM marketing What error is present in the sample code above? 1. Queries being combined with the UNION ALL statement are not allowed to have SELECT lists with a different number of expressions. 2. You are not allowed to use aggregate functions within two queries joined by a UNION ALL statement. 3. The UNION ALL statement incorrectly combines the "years" result from the first query with the "SUM (takehomepay)" result from the second query. 4. Unless the UNION ALL statement is replaced with a UNION statement, the queries will return duplicates. 5. The "emp_id" column from the second query must be renamed (or aliased) as "emp_num" so that it corresponds to the column name from the first query. Otherwise, the queries will not execute.
