Retrieving Data from SQLite Database using Cursor in Android

This code block retrieves data from a SQLite database using a cursor. If the cursor can move to the next record, meaning there is data available, it enters the if statement.

Inside the if statement, it retrieves the value of the first column ('COL1') using the 'getColumnIndex' method. This value is assigned to the '_id' variable.

An instance of the 'UserInfo' class is created and assigned to the 'utem' variable. The 'id', 'username', and 'userpass' properties of the 'utem' object are then set using the values obtained from the cursor.

Finally, the 'utem' object is returned, containing the retrieved data. If there is no data available, the 'utem' object remains null.
