c# - Execute multiple aggregates at once (SQL, LINQ).. or with better performance? -

-

I have a table with the record that contains a datetime column "CreationDate".

I need to get the following information for every for the last 90 days:

  • How many records were in total existence
  • How many records were added that day

I can definitely do this through a loop of counting, but this database will be killed 90 times ...

I am using C #, LINQ, SQL Server 2008.

are you looking for something like this? As with CTE (SELECT COUNT (*) over) (), Total Cost, CAST (Convert DateTime as VARCHAR, CreationDate, 101) as DateValue, * MyTable to WHERE CreationDate & gt; = DATEADD (DD, -90, GETDATE ())) DateValue, TotalCount, Order by date, as the line count from the CTE group by TotalCount;

Obfuscating Python code? -

I'm looking for a way to hide my Python source code. print "Hello World!" How can I encode this example so that it is not human-readable? 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. PS : If your program blur modules like this, you need to rename them with the .pyc suffix (I Not sure it will not break a day), or you can work with .pyo and run them with python -o ... .pyo ( Import should work). This will allow dragon to search your modules (otherwise, Python looks for the .py module).
