I am developing a query where I need that the result of a certain area of ​​"current area" of my current line Ho. My current row "+" The same area of ​​the previous row "(SQL Server 2008)

How do I do this by using the cursor?

Assign the previous line value in one variable: 

  declare @previosvalue varchar (100) = null; proclaim @ servbentvalue Announcement (100); Announce the crs cursor for the selected value from the table; Open CRS; Bring @ctitival ahead to CRC; While @@ fetch_status = 0 start - process here - In the first line, @previousvalue As it should be, since there is no 'back' of the first selection ... for some time where some sorting = @ currentvalueval and other conditions = @ previous price; set @previousvalue = @currentvalue; ahead of CRC @ CERTIFICATE CRAS; DLLL CRS;

I have been asked to use Base 64 but I'm not sure how. itemprop = "text"> It is limited only, first level ambiguous resolution, but has built-in: byte-code in Python Is a compiler for: dragon-o-m py_compile & lt; Your program.py & gt; creates a .pyo file with a byte-code, and where the docstrings are removed, etc. You can rename .pyo with the .py extension, and python & lt; Your program.py & gt; runs as your program, but it does not have your source code.

This will allow dragon to search your modules (otherwise, Python looks for the .py module).
