sql - Update all column values in a table with a column value of another table (related by a foreign key) -

-

I'm trying to populate a new column in the table with data in columns of another table. 

  UPDATE dbo.PackageSessionNodes SET Created_By = (dbo.PackageSessions, select dbo.PackageSessionNodes, where dbo.PackageSessions.PackageSessionId = dbo.PackageSessionNodes.PackageSessionId)
< p> the update puts fails because re-created more than one value of the subkey I obviously am a SQL Nob, so would appreciate any help.

Thx!

I think you are looking for this syntax: 

 < code> update dbo.PackageSessionNodes Set_B_B = left dbo.PackageSessionNodes pn from p.userid dbo.PackageSessions p on p.PackageSessionId = pn PackageSessionId

I believe that only a PackageSessionNode the Packejaseshn be?

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).
