Hi, today I want to share with you idea of batch processing aspect. It solves an issue with calling T-SQL Server procedures 1-by-1 request for example for inserts calls. And instead of calling 1-by-1 I prepared aspects that you call 1-by-1 but it do it in batches for example up to 100-by-100 like in my test example. Below you can find a code that includes aspect and a simple test of it. The most important quality factor Continue ReadingBatch Processing Aspect in C#
Hi, as a .NET/C# coder I found the issue that there is not Action<T> and Func<T, TResult> equivalents in Java environment. I am self-study this to prepare myself to the OCA certification and I had idea that I can use lambda expression and implement simple equivalents of C# delegates in the Java 8. Below you can find implementation with test cases. I found that the code can be very easy, because lambda expressions works as a anonymous Continue ReadingAction<T> and Func<T, TResult> in Java 8
So, I did it :P. p ;).
Hi, I am happy to announce, that my learn Java journey at the Hacker Rank is going very nice. Today I was very happy to solve the code puzzle named Java 1D Array (Part 2) and this puzzle has already 39.64% success rate. And it category Data Structure Challenges most of the code puzzles has more than 90% of success rate. So far, so good, I have in Java 313 points and 2067 rank :). I have Continue ReadingLearn Java so Far so Good Java 1D Array
Hi, some time ago I started learn Java language. I ma trying to self-study learn of the Java. And I have to say that the language is very nice and with deep knowledge of C# my progress is fast. I want to show you today here one of nice code puzzle solution named Tag Content Extractor. It take me some time. I started learn Java from very easy puzzles and every next one is more and more Continue ReadingLearn Java proof at Hacker Rank in Tag Content Extractor
Hi, today I would like to show you how you can use Extended Events Sessions on SQL Server 2008 or above. Extended Event Sessions are future of monitoring of the SQL Server. From many years solutions that used SQL Profiler Traces or DMV were not always accurate and fast. DMV queries could be very fast. However it is impossible to get statistics only per one sessions from DMV. And that is why I want to show you Continue ReadingTutorial of MS SQL Extended Events in 7 T-SQL Steps

Hi, today I would like to share with you idea of the Performance Counter Logger. This tool is for logging performance counters values and it solves issues with built-in PerfMon in Windows that collect data only for some time window and cannot auto pause when process not working. So I wrote Performance Counter Logger to solve that issue. it is very small almost trivial tool which has 60 lines of C# code. Tool was created by me Continue ReadingPerformance Counter Logger
Hi, today I want to show you simple technique which can be used when you need parameterised ORDER BY cause in T-SQL. Sometimes you may want to have elegant query. Example is from my today’s code review that I gave to colleague. On the Internet is very difficult to find such solution. So, I decided to show it to you here. There are many possible scenarios for this example usage. For example you may want to have Continue ReadingSQL Ninja uses ORDER BY with CASE
Hi, today I want to share with you very simple idea of using correctly TextWriter class. You can imagine that TextWriter is created on the network stream solution in SOA (WCF), REST (WebAPI) or Web (ASP.NET) application. When you write to that stream very often you could have a lot of unnecessary round-trips between clients and server. But there is nice technique with StringBuilder I want to share with you in below tests. I think nothing more Continue ReadingUsing of TextWriter by StringBuilder
