Simple method to constrain stored procedures by a collection

Wed, 25 Apr 2012 22:30:42 GMT

Passing a collection of ID's to filter a SQL query within a stored procedure is not natively supported. Consider this article which discusses methods for passing arrays into a stored procedure. Constraining a stored procedure's query has a simple work around, however. Passing the ID collection as a comma deliminated string allows the query to use LIKE to constrain the results. Note that the preceding and trailing commas are necessary. An example demonstrates how to do this easily.

Sometimes there is a need to search for a fragment in multiple columns. Which options does OpenAccess and LINQ provide to perform string matching? Into which SQL is the LINQ expression translated?

This post discuss about new T-SQL features in SQL Server 2012. The features which I am going to discuss here are Window Functions.

Entity framework and nhibernate too complex? Say hello to FluentData.

Tue, 21 Feb 2012 20:27:51 GMT

Are you tired of fighting with overly complex ORMs such as Entity Framework and NHibernate? Are you tired of poorly generated SQL or having to change your business objects to work with your ORM? Do you miss the power and performance of ADO.NET and SQL, but not the manual tedious work? If so FluentData might be the framework for you. FluentData is a Micro ORM that makes it simple to select, insert, update and delete data in a database. It gives the developer the power of ADO.NET but with the convenience of an ORM. It has a simple to use fluent API that uses SQL - the best and most suitable language to query data, and SQL or fluent builders to insert, update and delete data.

Making unit tests in SQL Server a first class citizen with Red Gate's

Mon, 13 Feb 2012 08:10:42 GMT

One area of unit testing that's always been a little tricky is testing anything with a database dependency. In part, this is because those tests often end up being dependent on the data itself which, of course, can be highly volatile. But it's also philosophically challenged in that if a unit test is to assess a discrete unit of code on the application tier then it probably shouldn't have dependencies on the data tier. This is where Red Gate's SQL Test comes in. It's entirely self-contained within SSMS and all it does is tests business logic in the database, just like those first class cousins in Visual Studio.
