How to add a column in a existing view in sql

Question

0.00/5 (No votes)

See more:

I already have a table (EMP_DETAILS), which is containing EMP_ID (Primary Key), FIRST_NAME, LAST_NAME, AGE, ADDRESS, SALARY, DEPT_ID (Foreign Key). I want to create a view of this table.

I already created a view for the table, but when I created that table I missed one column (FIRST_NAME).

I want to add that column in this existing view with out drop this. I already try to replace this but it had shown some nothing.

Can anybody please help me out from this.

I have another question:
How I join the above table view with the another table view
(DEP_DETAILS){DEPT_ID (Primary Key), DEPT_NAME}

Can you please help me to giving the actual syntax.

Use ALTER VIEW with the correct select query you want : http://msdn.microsoft.com/en-us/library/ms173846.aspx[^]

Use the query builder to create the select statement you want with the joins you need then create a view for that select statement.

Use the query designer to join your tables and views and select the data you want.

I tried the query

[ ALTER VIEW BISA1.EMPLOYEE_DETAILS_VIEW AS
SELECT EMP_ID, FIRST_NAME, LAST_NAME, AGE, ADDRESS, SALARY, DEPT_ID
FROM EMP_DETAILS;]

but it will give some error.

as per your comment you are working with sql server 2008 with oracle sql developer. there is a better microsoft product called sql server management studio express[^], it is free.
you can right click on view and design it directly
