Your SQL Server Needs Spring Cleaning, Too.

First things first: pick up that filthy keyboard, take it over to the trash can, turn it upside down, and give it a good, vigorous shake.

Evaluating the Randomness of SQL Server Random Number Functions

Microsoft provides T-SQL developers with three functions (rand, newid, and crypt_gen_random) for generating random numbers. Each of these functions is effective at returning random values, but feature sets associated with each function make them best suited to different use cases. This tip’s Solution section presents an overview of common use cases for random numbers in SQL Server along with references to learn more about random numbers in SQL Server.

Exploring the SQL Server CHOOSE Function

I preface a lot of what I write with whether or not it is for a “practical” use. One of the Simple Talk authors used this function in a forthcoming article. and I realized I hadn’t heard of it before (or I forgot about it… which is not completely unlikely.) The practical use was to generate some data and have at least a little variety to the values.

SQL Server Cursor Example

I know SQL cursors exist, but I am not sure how or why to use them. Can you provide a SQL cursor example? Can you give any guidance on when to use a SQL Server cursor?

Building AI Calls into the First Responder Kit

Using try catch in SQL Server stored procedures

A great new option that has been around since SQL Server 2005 is the ability to use the Try..Catch paradigm that exists in other development languages. Doing error handling in SQL Server has not always been the easiest thing, so this option definitely makes it much easier to code for and handle errors.
