Over the years I’ve seen lot’s of views created similar to this one. If the view is a join view, all components of the view must be updatable (not materialized). You may need to modify the SELECT statement in the SQL pane to return the rows to be modified. MSDN continues: To report the dependencies on a table, use sys.dm_sql_referencing_entities. Any view or stored procedure that references the dropped table must be explicitly dropped by using DROP VIEW or DROP PROCEDURE. It cannot use the ORDER BY clause or name a host variable. The operation is then performed on the base table upon which the view is defined. If you update such a view, the underlying tables may not be updated properly. However, you cannot always manipulate data via views. A view is updatable if the statement against the view can be translated into the corresponding statement against the underlying table.

Some views may draw components from two or more tables. In MySQL, views are not only query-able but also updatable. It means that you can use the INSERT or UPDATE statement to insert or update rows of the base table through the updatable view. Summary: in this tutorial, you will learn about Oracle updatable view and how to insert or update data in the base tables through a view.. A view behaves like a table because you can query data from it. To switch views for an already open object, right-click the object tab, and then select the preferred view. In Object Explorer, expand the database that contains the view and then expand Views. To modify table data through a view. To switch views for an already open object, on the Home tab, in the Views group, click the View arrow, and then select your preferred view. For example: Generally the argument is that if I put "SELECT *" rather than an explicit field list, then when my table changes so… When I run the view, the added column is not appearing in my result set!

In other words, MSSQL doesn't automagically warn you, or drop the view for you. For a multiple-table updatable view, INSERT can work if it inserts into a single table. Problem: You’ve added columns to the base table of one of your views, but the view isn’t reflecting the change. As the underlying data changes, when that query gets accessed, it reflects the changes to the data. In SQL Server a standard view is nothing but a query. This statement is invalid because one component of the join view is nonupdatable: To open an object in design view, right-click it in the Navigation Pane, and select Design View. A view is not updatable if any of the following conditions are true: Right-click the view and select Edit Top 200 Rows. INSERT: The insert table of an INSERT statement may be a view reference that is merged. I recently added a column to one of my core system tables referenced by a reporting view. A view may include an expression in a SELECT list. To retrieve or access information from a view, you use views like you use base tables. Summary: in this tutorial, we will show you how to create an updatable view and update data in the underlying table through the view.. Introduction to MySQL updatable views. However, certain views may not be updated (for example a view containing DISTINCT values, where a single row in the view may represent several rows in the base table). An updatable view is a view that will accept insert, delete and update commands, propagating changes back to the underlying tables. Solution When a view is created in SQL Server, metadata for the referenced table columns (column name and ordinal position) is persisted in the database. The rules for updatable join views are shown in the following table.

In the Results pane, locate the row to be changed or deleted.

I believe that some SQL database engines (not SQLite) facilitate updatable views automatically, if the view uses just one table or is a simple join of tables, showing only some of their columns (no calculations). The SELECT statement can name other views and tables, and it can use the WHERE, GROUP BY, and HAVING clauses. An updatable join view (also referred to as a modifiable join view) is a view that contains more than one table in the top-level FROM clause of the SELECT statement, and is not restricted by the WITH READ ONLY clause.
