Hi all...


Can anyone explain create view statement in sql.


Thanks in advance...

Hi all...


A SQL view is a virtual table and the SQL CRERATE VIEW statement is the SQL command that adds a new view to a SQL database.

A view can be accessed using the SQL SELECT statement like a table. A view is built by selecting data from one or more tables.

Some views can also support the SQL INSERT, SQL UPDATE and SQL DELETE statements. In that case, the view must refer to a single table and include all NOT NULL columns of that table.

Hi all...


SQL views are used because they can provide the following benefits / functions:

Database queries are simplified
Database complexity is hidden
Flexibility is increased - queries of views may not change when underlying
tables change
Security is increased - sensitive information can be excluded from a view

Hi all...


The SQL CREATE VIEW command is used as follows.

SQL CREATE VIEW Statement Syntax


CREATE VIEW <view_name> (
<column_name1>,
<column_name2>
) AS
<sql_select_statement>


The number of characters that can make up SQL names for tables, columns and views varies by DBMS. In many cases the limit is 30 characters. The leading character of the name must be alphabetic - not a number or special character. The name of a new view can not duplicate the name of an existing view or table and should not be the same as a SQL reserved word. The underscore character can be used to improve readability. List elements are seperated by commas.


Thanks...

I am glad to read it here.
