Cursors pl sql updating 100 women looking for man dating site in kuwait 2016
As you have seen, PL/SQL makes it very easy to populate a record from a row in a table.
But what if you want to change the contents of a row in a table by using a record?
Here’s an example: (Note that I usually add a “_cur” suffix to the names of my explicitly declared cursors.) Whenever you are fetching data from a cursor into PL/SQL variables, you should declare a record based on that cursor with %ROWTYPE and fetch into that record.
You can also, however, assign values directly to individual fields or even to the record as a whole by using the PL/SQL assignment operator (:=).
Let’s look at examples of the ways to populate a record.
Tables are made up of rows of data, each consisting of one or more columns, so it stands to reason that Oracle Database would make it as easy as possible to work with those rows of data inside a PL/SQL program.
And it does precisely that through its implementation of the datatype, such as a number or string.
