Same example is given below for explicit cursor but with For Loop, the For Loop cursors are more smart as there is no need to declare variables to fetch values in them and no need to open or close or to check w
I can't imagine using this feature in the context of a regular PL/SQL programming environment, but it will be extremely valuable in any migration projects. RETURN_RESULT Rather than defining explicit ref cursor out parameters, theRETURN_RESULTprocedure in theDBMS_SQLpackage allows you to pass th...

You can complete corresponding operations based on related attributes of an implicit cursor. The data stored in the workspace of an implicit cursor is irrelevant to a user-defined explicit cur...

PL/SQL employs an implicit cursor for each UPDATE, DELETE, or INSERT statement you execute in a program. You cannot, in other words, execute these statements within an explicit cursor, even if you want to. Explicit Cursors An explicit cursor is a SELECT statement that is explicitly defined ...
In a cursor-control task in which the motion of the cursor is rotated randomly relative to the movement of the hand, the sensed directions of hand and cursor are mutually biased. In our previous study, we used implicit and explicit measures of the bias of sensed hand direction toward the ...
