wi fi host port

Using Windows' Command Prompt, you can create a virtual network and share it to provide internet access to other devices:
Launch a Command Prompt with Administrator privileges and enter the following command:

netsh wlan set hostednetwork mode=allow ssid=sanjay key=7359977215

Change the SSID value to choose a different name if you want, and use "key" to set a password. This will create a virtual network adapter.
Start the new virtual adapter by running the following command:

netsh wlan start hostednetwork

Go to the Control Panel and open up the Network and Sharing Center. You should see your new virtual adapter listed there (as shown in the screenshot above). Click the "Local Area Connection" link (or whatever shows up next to "Connections").
Click the Properties button in the window that appears.
Head to the Sharing tab and then check the "Allow other network users to connect through this computer's Internet connection" box.
Use the drop down menu to select the virtual network adaptor you've created.
Click OK followed by Close.

What are Cursors?

What are Cursors?

A cursor is a temporary work area created in the system memory when a SQL statement is executed. A cursor contains information on a select statement and the rows of data accessed by it. This temporary work area is used to store the data retrieved from the database, and manipulate this data. A cursor can hold more than one row, but can process only one row at a time. The set of rows the cursor holds is called the active set.

There are two types of cursors in PL/SQL:

Implicit cursors:

These are created by default when DML statements like, INSERT, UPDATE, and DELETE statements are executed. They are also created when a SELECT statement that returns just one row is executed.

Explicit cursors:

They must be created when you are executing a SELECT statement that returns more than one row. Even though the cursor stores multiple records, only one record can be processed at a time, which is called as current row. When you fetch a row the current row position moves to next row.
