This->cursorSelectionComboBox->Size = System::Drawing::Size( 152, 21 ) I used raw input to draw My Cursors for each one of mice that connected to PC, although I Used Hooks for Reading mouse movement in another project.

When the user selects a mouse cursor in the ComboBox, the Control.Cursor property is set to the selected cursor, which updates the cursor for the Panel. The ComboBox contains all cursors provided by the Cursors class. The example creates a form that contains a ComboBox control, a Panel control, and a ListView control. The first one is l_budget whose initial value is 1,000,000.The following example demonstrates changing the mouse cursor using the Control.Cursor property, the Cursor class, and the Cursors class. In the declaration section, we declare three variables.
#Cursors code#
' Credit: ' || r_sales.credit || ' Remaining Budget: ' || l_budget ) ĮND Code language: SQL (Structured Query Language) ( sql )
#Cursors update#
update credit for the current customer UPDATEĭBMS_OUTPUT.PUT_LINE( 'Customer id: ' ||r_sales.customer_id || Declare a cursorīefore using an explicit cursor, you must declare it in the declaration section of a block or package as follows:īEGIN - reset credit limit of all customers UPDATE customers SET credit_limit = 0 The following illustration shows the execution cycle of an explicit cursor: Oracle defines an execution cycle that executes an SQL statement and associates a cursor with it. Explicit cursorsĪn explicit cursor is an SELECT statement declared explicitly in the declaration section of the current block or a package specification.įor an explicit cursor, you have control over its execution cycle from OPEN, FETCH, and CLOSE. The implicit cursor is not elegant when the query returns zero or multiple rows which cause NO_DATA_FOUND or TOO_MANY_ROWS exception respectively. Oracle internally manages the whole execution cycle of implicit cursors and reveals only the cursor’s information and statuses such as SQL%ROWCOUNT, SQL%ISOPEN, SQL%FOUND, and SQL%NOTFOUND. Whenever Oracle executes an SQL statement such as SELECT INTO, INSERT, UPDATE, and DELETE, it automatically creates an implicit cursor. PL/SQL has two types of cursors: implicit cursors and explicit cursors. Summary: in this tutorial, you will learn about PL/SQL cursor and its usage.Ī cursor is a pointer that points to a result of a query.
