Doubling a child's height at age 2 can provide an estimate of how tall that child will be in adulthood. (Boys are usually a little taller than that number and girls a little shorter.) That's because by 2 most children have reached the growth chart percentile they will stay on as they grow.nswer: A child's height at age 2 may be predictive of final adult height. But many factors can affect height. As they grow, children should be monitored regularly by a doctor to ensure they are growing properly and to detect any growth problems as soon as possible.
1.9 Cursors in PL/SQL. 1  Every SQL statement executed by the RDBMS has a private SQL area that contains information about the SQL statement and the set of data returned. In PL/SQL, a cursor is a name assigned to a specific private SQL area for a specific SQL statement.
This section describes how to use the system cursors. For more advanced tasks, such as creating custom cursors, see Cursors. You can associate a cursor with a window class by setting the hCursor member of the WNDCLASS or WNDCLASSEX structure. Otherwise, the default cursor is the arrow.When the mouse moves over a window, the window receives a WM_SETCURSOR message (unless another window has captured the mouse).therwise, if the application passes WM_SETCURSOR to DefWindowProc, the DefWindowProc function uses the following algorithm to set the cursor image: 1  If the window has a parent, forward the WM_SETCURSOR message to the parent to handle. 2  Otherwise, if the window has a class cursor, set the cursor to the class cursor.
