These are my links for July 14th through July 15th:

  • Read Intermediate Python | Leanpub – This book is intended as a concise intermediate level treatise on the Python programming language. There is a need for this due to the lack of availability of materials for python programmers at this level. The material contained in this book is targeted at the programmer that has been through a beginner level introduction to the Python programming language or that has some experience in a different object oriented programming language such as Java and wants to gain a more in-depth understanding of the Python programming language in a holistic manner. It is not intended as an introductory tutorial for beginners although programmers with some experience in other languages may find the very short tutorial included instructive.

    The book covers only a handful of topics but tries to provide a holistic and in-depth coverage of these topics. It starts with a short tutorial introduction to get the reader up to speed with the basics of Python; experienced programmers from other object oriented languages such as Java may find that this is all the introduction to Python that they need. This is followed by a discussion of the Python object model then it moves on to discussing object oriented programming in Python. With a firm understanding of the Python object model, it goes ahead to discuss functions and functional programming. This is followed by a discussion of meta-progr

  • How does the SQL Server Query Optimizer Works – blog x – direction obsessed – At the core of the SQL Server Database Engine are two major components: the Storage Engine and the Query Processor, also called the Relational Engine.

    Storage Engine: takes care of reading data between the disk and memory in a manner that optimizes concurrency while maintaining data integrity
    Query Processor: 1. takes care of devising a query plan (what algorithms/operators to implement) by Query Optimizer 2. execute the query according to that plan by Execution Engine

  • Understanding how SQL Server executes a query – If you are a developer writing applications that use SQL Server and you are wondering what exactly happens when you ‘run’ a query from your application, I hope this article will help you write better database code and will help you get started when you have to investigate performance problems.
  • BI: Beer Intelligence? · The “Select ALL” parameter option [SSRS] – You all know that report parameters can be populated through a query, right?  And multi-value parameters get this magical (Select All) item as first one in the dropdown list.  I used the word magical in the previous sentence because this (Select All) item is not a real one.  It’s a bit like a fata morgana: you can click it but it doesn’t really get selected.  It only appears that way in the dropdown.  But you can’t write an expression that tests if the (Select All) item is selected because it doesn’t really exist in the array.  The only thing it does is it selects all items when it gets clicked.
  • Set Select All as Default for Multi-Value Report Parameters in SQL Server Reporting Services – Most SQL Server Reporting Services (SSRS) reports contain multi-value report parameters and sometimes there be a requirement to set "Select All" as the default. There is not a simple way to set "Select All" as the default for an SSRS report, but in this tip I will demonstrate how to set "Select All" as the default parameter value.

  • DECLARE @local_variable (Transact-SQL) | Microsoft Docs – Variables are declared in the body of a batch or procedure with the DECLARE statement and are assigned values by using either a SET or SELECT statement. Cursor variables can be declared with this statement and used with other cursor-related statements. After declaration, all variables are initialized as NULL, unless a value is provided as part of the declaration.
