If you are still using the old Sybase DateTime datatype, it is a good idea to move your code to the more standard datatypes that were introduced in SQL Server 2008. Joe Celko explains why, and walks through some of the history of the TSQL way of storing and manipulating dates and times.

The PATINDEX function of SQL Server packs powerful magic, but it is easy to get it wrong. Phil Factor returns to the Workbench format to give a tutorial of examples, samples and cookbook ideas to demonstrate the ways that this underrated function can be of practical use. It is intended to be pasted into SSMS and used as a basis for experiment.

SQL Server 2008 introduced many new functional and performance improvements for data warehousing, and SQL Server 2008 R2 includes all these and more. This paper discusses how to use SQL Server 2008 R2 to get great performance as your data warehouse scales up. We present lessons learned during extensive internal data warehouse testing on a 64-core HP Integrity Superdome during the development of the SQL Server 2008 release, and via production experience with large-scale SQL Server customers. Our testing indicates that many customers can expect their performance to nearly double on the same hardware they are currently using, merely by upgrading to SQL Server 2008 R2 from SQL Server 2005 or earlier, and compressing their fact tables. We cover techniques to improve manageability and performance at high-scale, encompassing data loading (extract, transform, load), query processing, partitioning, index maintenance, indexed view (aggregate) management, and backup and restore.

With each revision, SharePoint becomes more a SQL Server Database application, with everything that implies for planning and deployment. There are advantages to this: SharePoint can make use of mirroring, data-compression and remote BLOB storage. It can employ advanced tools such as data file compression, and object-level restore. DBAs can employ familiar techniques to speed SharePoint applications. Bert explains the way that SharePoint and SQL Server interact.

This white paper describes how to use database mirroring to increase the availability of the replication stream in a transactional environment. The document covers setting up replication in a mirrored environment, the effect of mirroring partnership state changes, and the effect of mirroring failovers on replication. In addition, it describes how to use LSN-based initialization to recover from the failover of a mirrored Subscriber database.

I have noticed that available disk space on my SQL Server is getting low and I see a number of files getting generated in the replication snapshot folder. Because of these files there is a space issue on my server. Why are these files here and what can I do to resolve this problem?

When continuous data is displayed on a chart, such as a line chart, data is displayed very smoothly. But when non-continuous data is displayed on such a chart, the chart behavior is different. The continuous data is displayed correctly, but the non-continuous data is ignored on the chart. In such cases, handling of empty points in the dataset is required to make the data continuous and displayed correctly on the chart. In this tip we will look at how to implement a solution for this problem.
