No need for SYS_CONTEXT or cursor definitions. You do need a type so that, when the SQL is parsed, it can determine which columns are going to be returned. That said, you can easily write a script that will generate type and collection type definitions for one or more tables based on the data in … Read more
A View in Oracle and in other database systems is simply the representation of a SQL statement that is stored in memory so that it can easily be re-used. For example, if we frequently issue the following query SELECT customerid, customername FROM customers WHERE countryid=’US’; To create a view use the CREATE VIEW command as … Read more
Yes. By default, ASP.NET MVC checks first in \Views\[Controller_Dir]\, but after that, if it doesn’t find the view, it checks in \Views\Shared. The shared directory is there specifically to share Views across multiple controllers. Just add your View to the Shared subdirectory and you’re good to go. If you do return View(“~/Views/Wherever/SomeDir/MyView.aspx”) You can return … Read more
You can also remove the dim effect by code with the following: dialog.getWindow().clearFlags(WindowManager.LayoutParams.FLAG_DIM_BEHIND);
It Depends. It totally depends on what you are viewing through view. But most probably reducing your effort and giving higher performance. When SQL statement references a nonindexed view, the parser and query optimizer analyze the source of both the SQL statement and the view and then resolve them into a single execution plan. There … Read more
The context method is described here: http://docs.oracle.com/cd/B28359_01/network.111/b28531/app_context.htm e.g. (example adapted from the above link) CREATE CONTEXT dates_ctx USING set_dates_ctx_pkg; CREATE OR REPLACE PACKAGE set_dates_ctx_pkg IS PROCEDURE set(d1 in date, d2 in date); END; / CREATE OR REPLACE PACKAGE BODY set_dates_ctx_pkg IS PROCEDURE set(d1 in date, d2 in date) IS BEGIN DBMS_SESSION.SET_CONTEXT(‘dates_ctx’, ‘d1′, TO_CHAR(d1,’DD-MON-YYYY’)); DBMS_SESSION.SET_CONTEXT(‘dates_ctx’, ‘d2’, … Read more
As already stated you can’t. A possible solution would be to implement a stored function, like: CREATE FUNCTION v_emp (@pintEno INT) RETURNS TABLE AS RETURN SELECT * FROM emp WHERE emp_id=@pintEno; This allows you to use it as a normal view, with: SELECT * FROM v_emp(10)
sp_refreshview to fix the view, or use WITH SCHEMABINDING in the view definition If a view is not created with the SCHEMABINDING clause, sp_refreshview should be run when changes are made to the objects underlying the view that affect the definition of the view. Otherwise, the view might produce unexpected results when it is queried.
I don’t think MySQL supports materialized views which is what you would need, but it wouldn’t help you in this situation anyway. Whether the index is on the view or on the underlying table, it would need to be written and updated at some point during an update of the underlying table, so it would … Read more
The context processor you have written should work. The problem is in your view. Are you positive that your view is being rendered with RequestContext? For example: def test_view(request): return render_to_response(‘template.html’) The view above will not use the context processors listed in TEMPLATE_CONTEXT_PROCESSORS. Make sure you are supplying a RequestContext like so: def test_view(request): return … Read more
