Understanding DBCC SHOWCONTIG

Image
DBCC SHOWCONTIG is a wonderful tool which helps you to understand quite a bit more about your system than is obvious at first glance. And, frankly, the documentation doesn't use terminology that makes it very obvious either. So, this article will focus on a few of the big ideas behind the tool using SQL Server, and how you can use it to better understand what is going on inside your SQL Server box. Probably one of the most significant performance problems found in databases is centered around table data fragmentation. One situation that may be analogous to table fragmentation might be an index at the end of a large book. A single index entry in such a book might point to several pages scattered throughout the book. You must then scan each page for the specific information you require. This differs significantly from the index of the phone book which stores its data in sorted order. A typical query for the name "Jones" might span multiple consecutive pages, but are always ...

ARRAY In SQL Server 2000

Image
On a number of occasions that I have regretted the fact that there is no such thing as Array in Microsoft SQL Server's Transact-SQL. Lots of other SQL programmers would mention the same thing. The array is one of the most common and highly used programming structures. Indeed, T-SQL does not provide for the fully functional array structure. However, SQL 2000 introduced the new feature called a variable of type table, which allows for mimicking an array and/or using it instead of SQL Server cursor. It can be a challenge to pass such a list of values to a stored procedure. In earlier times I had been using so called composite queries, or dynamic SQL. It includes putting together a string to be compiled and executed using EXECUTE statement. For example: CREATE PROCEDURE CustomerByRegion @List varchar(100) AS declare @sql varchar(1000) set @sql = 'select * from Customers where Region IN (' + @List + ')' execute (@sql) -- call procedure declare @List varchar(100) set ...
