LINQ To Sql - Getting a Command Object from a Query

Mon, 27 Aug 2007 05:46:02 GMT

LINQ to SQL is all about returning object from database queries, but sometimes it's actually useful to use good old DataReaders or DataTables - especially in ASP.NET applications that use DataBinding. Entities are objects and databinding requires Reflection which is very slow, compared to a DataReader. Luckily LINQ to SQL provides the abillity to retrieve a Sql Command object that can be used to return an alternate result set.

Converting between Win32 COLORREF and .NET Color

Thu, 23 Aug 2007 05:31:08 GMT

If you are ever rewriting an MFC/Win32 program in .NET, you need to be aware that you cannot convert directly between a COLORREF value and a .NET Color structure. The byte order is different and will need to be swapped.

SQL SERVER - 2005 - List All The Column With Specific Data Types

Tue, 14 Aug 2007 04:30:09 GMT

SQL Server 2005 has new datatype of VARCHAR(MAX), we decided to change all our TEXT datatype columns to VARCHAR(MAX). The reason to do that as TEXT datatype will be deprecated in future version of SQL Server and VARCHAR(MAX) is superior to TEXT datatype in features. We run following script to identify all the columns which are TEXT datatype and developer converts them to VARCHAR(MAX) ...see the script here

LINQ to SQL and Dynamic Queries and Expressions?

Mon, 13 Aug 2007 11:08:49 GMT

Continuing my experiments with LINQ in the middle tier I ran into another problem: Inability to make LINQ run any dynamic operations that are not defined explicitly in the LINQ to SQL import. For building a generic business framework that doesn't have concrete type references (to say a PK field) but dynamically needs to create SQL to query data. Even relatively simple things like retrieve a single record by primary key where primary key is dynamic not explicit is not easily accomplished without getting real low level into Lambda expression creation.

SQL SERVER - UDF - Validate Integer Function

Sun, 12 Aug 2007 23:32:07 GMT

I received quite a good feedback about my post about SQL SERVER - Validate Field For DATE datatype using function ISDATE() One of the most interesting comment I received from my reader from Canada. I was suggested just like ISDATE() to write about ISNUMERIC() which can be used to validate numeric values. As per BOL: ISNUMERIC returns 1 when the input expression evaluates to a valid numeric data type; otherwise it returns 0. ISNUMERIC returns 1 for some characters that are not numbers, such as plus (+), minus (-), and valid currency symbols such as the dollar sign ($). Now this is issue with ISNUMERIC() function. It even suggest variable as numeric when it is not. I use following function to validate instead of ISNUMERIC() to validate if number is numeric or not.

LINQ to SQL and attaching Entities

Sun, 12 Aug 2007 18:05:50 GMT

I have been experimenting with LINQ to SQL in the middle tier and have run into the apparently common issue of re-attaching entities to a DataContext in cross tier scenarios. Either the support re-attachment is not there or it is broken but either way it doesn't work which makes it pretty tough to use LINQ to SQL in the middle tier.

Use a CTE along with ROW_NUMBER() to Paginate Records in SQL 2005

You may be familiar with ROW_NUMBER(), but did you know you'll also need to combine that with a Common Table Expression (CTE) to paginate through your records?

Efficient data paging with SQL Server 2005 using ROW_NUMBER()

Thu, 09 Aug 2007 11:01:02 GMT

Paging large amounts of data in SQL Server 2000 used to be a real pain, creating temporary tables, suffering bad performance after the first few batches of data or using ROWCOUNT to ignore large numbers of rows. Luckily SQL Server 2005 delivers a couple of new functions to make efficient painless data paging a reality.

C# Principal Architect Matt Warren and Lead PM Luca Bolognese detail the pipeline that hastens your LINQ queries to execution. Matt did most of the design and implementation of this code. His explanations are vivid and useful. The drawings are well organized, well executed, and clearly explained. Matt and Luca have worked together for years, and they make an excellent team.

SQL SERVER - Stop SQL Server Immediately Using T-SQL

Mon, 06 Aug 2007 05:06:28 GMT

This question has came up many quite a few times with our development team as well as emails I have received about how to stop SQL Server immediately (due to accidentally ran t-sql, business logic or just need of to stop SQL Server using T-SQL). Answer is very simple, run following command in SQL Editor. If you want to shutdown the system without performing checkpoints in every database and without attempting to terminate all user processes use following command.
