Designing a table can be a little complicated if you don’t have the correct knowledge of data types, relationships, and even column properties. In this tip, Brady Upton goes over the column properties and provides examples.
Today Steve Jones talks about those great DBAs, the Exceptional ones that do more than just respond to issues or set up monitoring on their systems.
XML Indexes make a huge difference to the speed of XML queries, as Seth Delconte explains; and demonstrates by running queries against half a million XML employee records. The execution time of a query is reduced from two seconds to being too quick to measure, purely by creating the right type of secondary index for the query.
There's a hole in the SQL Server platform. No log reader comes with the product and Steve Jones thinks Microsoft should build one and include it.
Sometimes it is necessary to search for specific content inside documents stored in a SQL Server database. Is it possible to do this in SQL Server? Can I run T-SQL queries and find content inside Microsoft Word files? Yes, now with SQL Server 2012 you can do a semantic search.
Today Steve Jones talks about the differences between development and production and how it can be good to spend a little doing the other type of work.
SQL Server Indexes need to be effective. It is wrong to have too few or too many. The ones you create must ensure that the workload reads the data quickly with a minimum of I/O. As well as a sound knowledge of the way that relational databases work, it helps to be familiar with the Dynamic Management Objects that are there to assist with your indexing strategy.
Many companies now have a requirement to keep data for long periods of time. While this data does have to be available if requested, it usually does not need to be accessible by the application for any current transactions. Data that falls into this category are a good candidate for archival.
This is the method that Geoff Albin has used for years to monitor the CPU on his SQL Servers.
