It is important for developers and DBAs to be able to determine the interdependencies of any database object. Perhaps you need to work out what process is accessing that view you want to alter, or maybe find out whether that table-type you wish to change is being used. What are all these dependencies? How do you work out which are relevant? Phil Factor explains.
As data professionals, we might carry lots of information with us that relates to our organization. Will we get caught up in government issues as we cross borders?
Oracle offers a results cache in the database (from 11.2 onwards) and in PL/SQL (again, from 11.2 onwards) which can greatly reduce execution time of repeated statements when insert/update/delete activity is not heavy. The mechanism in PL/SQL, however, may not work as expected with global temporary tables. Using a slightly modified example, Jonathan Lewis looks at what you might see when using this option.
The CAP Theorem talks about the properties of distributed systems, and how you can really only have two of them in any system.
A quick tip to help you set your object names to your preferred case in T-SQL code.
When you build applications that store records in SQL Server you will most likely have to store date and time values as part of the data. To manage all the different date related tasks you might need to perform Microsoft has introduced a number of date functions. In this stairway I will be exploring those date and time functions.
If you're on SQL Server 2012 or greater, you definitely want to become familiar with all of the extensions to the windowing functions first introduced in SQL Server 2005 – they may give you some pretty serious performance boosts when revisiting code that is still running "the old way." Aaron Bertrand explains.
SQLXML isn't exactly new technology, and parts of it aren't pretty, but if you need to heave vast quantities of XML data into a SQL Server database then you may come to appreciate the raw speed of which it's capable. Adam Aspin shows how to configure the SQL XML Bulk Loader tool for optimal data loading performance.
