Oracle Series: REF CursorIn the Oracle series above: Cursor (see:http://blog.csdn.net/qfs_v/archive/2008/05/06/2404794.aspx)Mention a thought: how do I get cursors to be passed as parameters? To solve this problem, you need to use the REF Cursor.1,

Today, we will briefly summarize the usage of cursor in PL/SQL. Cursor category: -- Explicit cursor-- Static cursor | | -- Implicit cursorCursor |-- Strong type (Restriction), specifying the return type-- Dynamic Cursor -- ref cursor |-- Weak type

C # basics: differences between ref and out The difference between ref and out is that in C #, you can pass parameters either by value or by reference. You can pass a parameter through reference to allow function members to change the parameter

Using system; using system. collections. generic; using system. in text; namespace CSHARP, the ref and out keywords use {class program {/* parameter to describe the difference between * ref and out in C #. You can either pass parameters through

No.1 Params A keyword that allows a method (function) to have a variable parameter. Principle: No other arguments are allowed after the params keyword in the method declaration, and only one params keyword is allowed in the method

C # has three keywords-Ref, out, And Params. Although I do not like these three keywords, they are suspected to damage the object-oriented feature. But since M $ is integrated into the C # system, let's take a look at the parameter modifiers ref,
