tsql - How to make table dynamic in sql -

-

Does anybody know how to run a table based on the variable is to write the script in the stored proc (or it is possible Hence?)? For example: I have names of 3 tables named Customer, Supplier, and Support

When user input 1, then table customer, 2 table supplier and 3 support table support 

 < Input code> input input; If @input = 1 declares, then @Tale Vivarkar (50); Set @table = 'Client' end if declared @input = 2, then 'Taylor Wirt (50); Set @table = 'Supplier' end if @input = 3 is declared, table workers (50); Set @table = 'support' and select * INTO ## test from @table

< P> Yes, you can do this by using the dynamic SQL "EXEC" or "Sp_Executesql" command. Example: 

  Use Northwind make table #MyTemp (RowID int IDENTITY, LastName varchar (20)) DECLARE @SQL nvarchar (250) SET @sQL = '# Include in the Employee Choose the last name from the employee; ' Execute SP_executesql @SQL

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).
