We are living in a time where businesses and the people running them often change their mind. I won’t be going into details of why is that so, let’s just say it is a given, and let’s say they are right. It gives them the competitive edge when they are flexible. It is on us […]
There are several ways to find a stored procedure in the server by name: we can query sys.procedures, syscomments, or information_scema.routines. Respective examples would be: or or
Software Developer, a “Programmer” even an “Engineer” or a “Craftsman“, although there are substantial differences between these according to some people, when we say any of them we mean one thing….an organism that transforms coffee into code 🙂 so I will continue with the term “Developer” and I wouldn’t like to go into that discussion […]
The MSDN documentation for datetime recommends using datetime2. datetime2 has larger date range, a larger default fractional precision, and optional user-specified precision. Also depending on the user-specified precision it may use less storage. Furthermore, datetime2 has a date range of “0001 / 01 / 01” through “9999 / 12 / 31” while the datetime type […]
To get all stored procedures related to a table: Option 1: SELECT DISTINCT so.name FROM syscomments sc INNER JOIN sysobjects so ON sc.id=so.id WHERE sc.TEXT LIKE ‘%tablename%’ Option2: SELECT DISTINCT o.name, o.xtype FROM syscomments c INNER JOIN sysobjects o ON c.id=o.id WHERE c.TEXT LIKE ‘%tablename%’
Here’s a code snippet to remove duplicate rows in a table: WITH CTE (Column1, Column2, DuplicateCount) AS ( SELECT Column1,Column2, ROW_NUMBER() OVER(PARTITION BY Column1,Column2 ORDER BY Column1) AS DuplicateCount FROM TheTable ) DELETE FROM CTE WHERE DuplicateCount > 1 GO More on Common Table Expressions(CTE) can be found here: http://msdn.microsoft.com/en-us/library/ms190766(v=sql.105).aspx
A little helper query I came accross, very useful if you want to find all the tables that contain a specific column: SELECT c.name AS ColName, t.name AS TableName FROM sys.columns c JOIN sys.tables t ON c.object_id = t.object_id WHERE c.name LIKE ‘%ColumnName%’ What it basically does is that it will do a join on […]
It is pretty hard writing an article on something that so many super cool authors have written books about. But, as I said it is my own experience learning and embracing TDD that I want to share here so that maybe I can help someone out there that can relate to this. And also I […]
There have been many questions I encountered lately of what are the best practices / guidances that you can take up on when designing an application. Wheather that’s an ASP.NET application or any other type of application that uses object oriented principles. First and upmost, let me begin with probably one of the most important principles […]
