Determine Tables Sizes in SQL Server

Everyone is worried about their database size. Even though storage is relatively cheap, if your database is growing linearly or exponentially, you’re going to run into issues down the road. One quick way to check things out is to look at your table sizes. I looked all over the web and found Mitch Sellers’ blog with several great SQL Table Size scripts. Here are 2 of the good ones from the comments: EXEC sp_MSforeachtable @command1=”EXEC sp_spaceused ‘?'” This method is quick, but not very clean.

Great Circles in SQL Server 2005 and SQL Server 2000

Recently, I had a request to calculate the distance between 2 GPS coordinates. Now, the system I am working with is SQL Server 2005. SQL Server 2008 gives us the geography data type, which is great and has a lot of powerful features. But, if you’re using SQL Server 2000 or 2005, you won’t have access to any spatial data types. Now, the table i was working with had the city name along with the Latitude and Longitude information. So, I went over to wikipedia and got the formula for calculating distance using great circles. I won’t go into the … Continue reading Great Circles in SQL Server 2005 and SQL Server 2000
